OpenStack-Train 部署指南

OpenStack 简介

OpenStack 是一个社区,也是一个项目。它提供了一个部署云的操作平台或工具集,为组织提供可扩展的、灵活的云计算。

作为一个开源的云计算管理平台,OpenStack 由nova、cinder、neutron、glance、keystone、horizon等几个主要的组件组合起来完成具体工作。OpenStack 支持几乎所有类型的云环境,项目目标是提供实施简单、可大规模扩展、丰富、标准统一的云计算管理平台。OpenStack 通过各种互补的服务提供了基础设施即服务(IaaS)的解决方案,每个服务提供 API 进行集成。

openEuler 22.03-LTS版本官方源已经支持 OpenStack-Train 版本,用户可以配置好 yum 源后根据此文档进行 OpenStack 部署。

约定

OpenStack 支持多种形态部署,此文档支持ALL in One以及Distributed两种部署方式,按照如下方式约定:

ALL in One模式:

忽略所有可能的后缀

Distributed模式:

以 `(CTL)` 为后缀表示此条配置或者命令仅适用`控制节点`
以 `(CPT)` 为后缀表示此条配置或者命令仅适用`计算节点`
以 `(STG)` 为后缀表示此条配置或者命令仅适用`存储节点`
除此之外表示此条配置或者命令同时适用`控制节点`和`计算节点`

注意

涉及到以上约定的服务如下:

  • Cinder
  • Nova
  • Neutron

准备环境

环境配置

  1. 安装和启用OpenStack Train yum源

    yum update
    yum install openstack-release-train
    yum clean all && yum makecache
    

    注意:如果你的环境的YUM源没有启用EPOL,需要同时配置EPOL

    vi /etc/yum.repos.d/openEuler.repo
    
    [EPOL]
    name=EPOL
    baseurl=http://repo.openeuler.org/openEuler-22.03-LTS/EPOL/main/$basearch/
    enabled=1
    gpgcheck=1
    gpgkey=http://repo.openeuler.org/openEuler-22.03-LTS/OS/$basearch/RPM-GPG-KEY-openEuler
    EOF
    
  2. 修改主机名以及映射

    设置各个节点的主机名

    hostnamectl set-hostname controller                                                            (CTL)
    hostnamectl set-hostname compute                                                               (CPT)
    

    假设controller节点的IP是10.0.0.11,compute节点的IP是10.0.0.12(如果存在的话),则于/etc/hosts新增如下:

    10.0.0.11   controller
    10.0.0.12   compute
    

安装 SQL DataBase

  1. 执行如下命令,安装软件包。

    yum install mariadb mariadb-server python3-PyMySQL
    
  2. 执行如下命令,创建并编辑 /etc/my.cnf.d/openstack.cnf 文件。

    vim /etc/my.cnf.d/openstack.cnf
    
    [mysqld]
    bind-address = 10.0.0.11
    default-storage-engine = innodb
    innodb_file_per_table = on
    max_connections = 4096
    collation-server = utf8_general_ci
    character-set-server = utf8
    

    注意

    其中 bind-address 设置为控制节点的管理IP地址。

  3. 启动 DataBase 服务,并为其配置开机自启动:

    systemctl enable mariadb.service
    systemctl start mariadb.service
    
  4. 配置DataBase的默认密码(可选)

    mysql_secure_installation
    

    注意

    根据提示进行即可

安装 RabbitMQ

  1. 执行如下命令,安装软件包。

    yum install rabbitmq-server
    
  2. 启动 RabbitMQ 服务,并为其配置开机自启动。

    systemctl enable rabbitmq-server.service
    systemctl start rabbitmq-server.service
    
  3. 添加 OpenStack用户。

    rabbitmqctl add_user openstack RABBIT_PASS
    

    注意

    替换 RABBIT_PASS,为 OpenStack 用户设置密码

  4. 设置openstack用户权限,允许进行配置、写、读。

    rabbitmqctl set_permissions openstack ".*" ".*" ".*"
    

安装 Memcached

  1. 执行如下命令,安装依赖软件包。

    yum install memcached python3-memcached
    
  2. 编辑 /etc/sysconfig/memcached 文件。

    vim /etc/sysconfig/memcached
    
    OPTIONS="-l 127.0.0.1,::1,controller"
    
  3. 执行如下命令,启动 Memcached 服务,并为其配置开机启动。

    systemctl enable memcached.service
    systemctl start memcached.service
    

    注意

    服务启动后,可以通过命令memcached-tool controller stats确保启动正常,服务可用,其中可以将controller替换为控制节点的管理IP地址。

安装 OpenStack

Keystone 安装

  1. 创建 keystone 数据库并授权。

    mysql -u root -p
    
    MariaDB [(none)]> CREATE DATABASE keystone;
    MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
    IDENTIFIED BY 'KEYSTONE_DBPASS';
    MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
    IDENTIFIED BY 'KEYSTONE_DBPASS';

    解释

    [default]部分,启用计算和元数据的API,配置RabbitMQ消息队列入口,配置my_ip,启用网络服务neutron;

    [api_database] [database]部分,配置数据库入口;

    [api] [keystone_authtoken]部分,配置身份认证服务入口;

    [vnc]部分,启用并配置远程控制台入口;

    [glance]部分,配置镜像服务API的地址;

    [oslo_concurrency]部分,配置lock path;

    [placement]部分,配置placement服务的入口。

    注意

    替换 RABBIT_PASS 为 RabbitMQ 中 openstack 账户的密码;

    配置 my_ip 为控制节点的管理IP地址;

    替换 NOVA_DBPASS 为nova数据库的密码;

    替换 NOVA_PASS 为nova用户的密码;

    替换 PLACEMENT_PASS 为placement用户的密码;

    替换 NEUTRON_PASS 为neutron用户的密码;

    替换METADATA_SECRET为合适的元数据代理secret。

    额外

    确定是否支持虚拟机硬件加速(x86架构):

    egrep -c '(vmx|svm)' /proc/cpuinfo                                                             (CPT)
    

    如果返回值为0则不支持硬件加速,需要配置libvirt使用QEMU而不是KVM:

    vim /etc/nova/nova.conf                                                                        (CPT)
    
    [libvirt]
    virt_type = qemu
    

    如果返回值为1或更大的值,则支持硬件加速,则virt_type可以配置为kvm

    注意

    如果为arm64结构,还需要在计算节点执行以下命令

    
    mkdir -p /usr/share/AAVMF
    chown nova:nova /usr/share/AAVMF
    
    ln -s /usr/share/edk2/aarch64/QEMU_EFI-pflash.raw \
          /usr/share/AAVMF/AAVMF_CODE.fd
    ln -s /usr/share/edk2/aarch64/vars-template-pflash.raw \

    su -s /bin/sh -c "cinder-manage db sync" cinder                                                (CTL)
    
  7. 配置nova:

    vim /etc/nova/nova.conf                                                                        (CTL)
    
    [cinder]
    os_region_name = RegionOne
    
  8. 重启计算API服务

    systemctl restart openstack-nova-api.service
    
  9. 启动cinder服务

    systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service               (CTL)
    systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service                (CTL)
    
    systemctl enable rpcbind.service nfs-server.service tgtd.service iscsid.service \              (STG)
                     openstack-cinder-volume.service \
                     openstack-cinder-backup.service
    systemctl start rpcbind.service nfs-server.service tgtd.service iscsid.service \               (STG)
                    openstack-cinder-volume.service \
                    openstack-cinder-backup.service
    

    注意

    当cinder使用tgtadm的方式挂卷的时候,要修改/etc/tgt/tgtd.conf,内容如下,保证tgtd可以发现cinder-volume的iscsi target。

    include /var/lib/cinder/volumes/*
    
  10. 验证

    source ~/.admin-openrc
    openstack volume service list
    

horizon 安装

  1. 安装软件包

    yum install openstack-dashboard
    
  2. 修改文件

    修改变量

    vim /etc/openstack-dashboard/local_settings
    
    OPENSTACK_HOST = "controller"
    ALLOWED_HOSTS = ['*', ]
    
    SESSION_ENGINE = 'django.contrib.sessions.backends.cache'
    
    CACHES = {
    'default': {
         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
         'LOCATION': 'controller:11211',
        }
    }
    
    OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST
    OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
    OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"
    OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"
    
    OPENSTACK_API_VERSIONS = {
        "identity": 3,
        "image": 2,
        "volume": 3,
    }
    
  3. 重启 httpd 服务

    systemctl restart httpd.service memcached.service
    
  4. 验证 打开浏览器,输入网址http://HOSTIP/dashboard/,登录 horizon。

    注意

    替换HOSTIP为控制节点管理平面IP地址

Tempest 安装

Tempest是OpenStack的集成测试服务,如果用户需要全面自动化测试已安装的OpenStack环境的功能,则推荐使用该组件。否则,可以不用安装。

  1. 安装Tempest

    yum install openstack-tempest
    
  2. 初始化目录

    tempest init mytest
    
  3. 修改配置文件。

    cd mytest
    vi etc/tempest.conf
    

    tempest.conf中需要配置当前OpenStack环境的信息,具体内容可以参考官方示例

  4. 执行测试

    tempest run
    
  5. 安装tempest扩展(可选) OpenStack各个服务本身也提供了一些tempest测试包,用户可以安装这些包来丰富tempest的测试内容。在Train中,我们提供了Cinder、Glance、Keystone、Ironic、Trove的扩展测试,用户可以执行如下命令进行安装使用:

    yum install python3-cinder-tempest-plugin python3-glance-tempest-plugin python3-ironic-tempest-plugin python3-keystone-tempest-plugin python3-trove-tempest-plugin
    

Ironic 安装

Ironic是OpenStack的裸金属服务,如果用户需要进行裸机部署则推荐使用该组件。否则,可以不用安装。

  1. 设置数据库

    裸金属服务在数据库中存储信息,创建一个ironic用户可以访问的ironic数据库,替换IRONIC_DBPASSWORD为合适的密码

    mysql -u root -p
    
    MariaDB [(none)]> CREATE DATABASE ironic CHARACTER SET utf8;
    MariaDB [(none)]> GRANT ALL PRIVILEGES ON ironic.* TO 'ironic'@'localhost' \
    IDENTIFIED BY 'IRONIC_DBPASSWORD';
    MariaDB [(none)]> GRANT ALL PRIVILEGES ON ironic.* TO 'ironic'@'%' \
    IDENTIFIED BY 'IRONIC_DBPASSWORD';
    
  2. 安装软件包

    yum install openstack-ironic-api openstack-ironic-conductor python3-ironicclient
    

    启动服务

    systemctl enable openstack-ironic-api openstack-ironic-conductor
    systemctl start openstack-ironic-api openstack-ironic-conductor
    
  3. 创建服务用户认证

    1、创建Bare Metal服务用户

    openstack user create --password IRONIC_PASSWORD \
                          --email ironic@example.com ironic
    openstack role add --project service --user ironic admin
    openstack service create --name ironic \
                             --description "Ironic baremetal provisioning service" baremetal
    

    2、创建Bare Metal服务访问入口

    openstack endpoint create --region RegionOne baremetal admin http://$IRONIC_NODE:6385
    openstack endpoint create --region RegionOne baremetal public http://$IRONIC_NODE:6385
    openstack endpoint create --region RegionOne baremetal internal http://$IRONIC_NODE:6385
    
  4. 配置ironic-api服务

    配置文件路径/etc/ironic/ironic.conf

    1、通过connection选项配置数据库的位置,如下所示,替换IRONIC_DBPASSWORDironic用户的密码,替换DB_IP为DB服务器所在的IP地址:

    [database]
    
    # The SQLAlchemy connection string used to connect to the
    # database (string value)
    
    connection = mysql+pymysql://ironic:IRONIC_DBPASSWORD@DB_IP/ironic
    

    2、通过以下选项配置ironic-api服务使用RabbitMQ消息代理,替换**RPC_***为RabbitMQ的详细地址和凭证

    [DEFAULT]
    
    # A URL representing the messaging driver to use and its full
    # configuration. (string value)
    
    transport_url = rabbit://RPC_USER:RPC_PASSWORD@RPC_HOST:RPC_PORT/
    

    用户也可自行使用json-rpc方式替换rabbitmq

    3、配置ironic-api服务使用身份认证服务的凭证,替换PUBLIC_IDENTITY_IP为身份认证服务器的公共IP,替换PRIVATE_IDENTITY_IP为身份认证服务器的私有IP,替换IRONIC_PASSWORD为身份认证服务中ironic用户的密码:

    [DEFAULT]
    
    # Authentication strategy used by ironic-api: one of
    # "keystone" or "noauth". "noauth" should not be used in a
    # production environment because all authentication will be
    # disabled. (string value)
    
    auth_strategy=keystone
    
    [keystone_authtoken]
    # Authentication type to load (string value)
    auth_type=password
    # Complete public Identity API endpoint (string value)
    www_authenticate_uri=http://PUBLIC_IDENTITY_IP:5000
    # Complete admin Identity API endpoint. (string value)
    auth_url=http://PRIVATE_IDENTITY_IP:5000
    # Service username. (string value)
    username=ironic
    # Service account password. (string value)
    password=IRONIC_PASSWORD
    # Service tenant name. (string value)
    project_name=service
    # Domain name containing project (string value)
    project_domain_name=Default
    # User's domain name (string value)
    user_domain_name=Default
    

    4、创建裸金属服务数据库表

    ironic-dbsync --config-file /etc/ironic/ironic.conf create_schema
    

    5、重启ironic-api服务

    sudo systemctl restart openstack-ironic-api
    
  5. 配置ironic-conductor服务

    1、替换HOST_IP为conductor host的IP

    [DEFAULT]
    
    # IP address of this host. If unset, will determine the IP
    # programmatically. If unable to do so, will use "127.0.0.1".
    # (string value)
    
    my_ip=HOST_IP
    

    2、配置数据库的位置,ironic-conductor应该使用和ironic-api相同的配置。替换IRONIC_DBPASSWORDironic用户的密码,替换DB_IP为DB服务器所在的IP地址:

    [database]
    
    # The SQLAlchemy connection string to use to connect to the
    # database. (string value)
    
    connection = mysql+pymysql://ironic:IRONIC_DBPASSWORD@DB_IP/ironic
    

    3、通过以下选项配置ironic-api服务使用RabbitMQ消息代理,ironic-conductor应该使用和ironic-api相同的配置,替换**RPC_***为RabbitMQ的详细地址和凭证

    [DEFAULT]
    
    # A URL representing the messaging driver to use and its full
    # configuration. (string value)
    
    transport_url = rabbit://RPC_USER:RPC_PASSWORD@RPC_HOST:RPC_PORT/
    

    用户也可自行使用json-rpc方式替换rabbitmq

    4、配置凭证访问其他OpenStack服务

    为了与其他OpenStack服务进行通信,裸金属服务在请求其他服务时需要使用服务用户与OpenStack Identity服务进行认证。这些用户的凭据必须在与相应服务相关的每个配置文件中进行配置。

    [neutron] - 访问OpenStack网络服务
    [glance] - 访问OpenStack镜像服务
    [swift] - 访问OpenStack对象存储服务
    [cinder] - 访问OpenStack块存储服务
    [inspector] - 访问OpenStack裸金属introspection服务
    [service_catalog] - 一个特殊项用于保存裸金属服务使用的凭证,该凭证用于发现注册在OpenStack身份认证服务目录中的自己的API URL端点
    

    简单起见,可以对所有服务使用同一个服务用户。为了向后兼容,该用户应该和ironic-api服务的[keystone_authtoken]所配置的为同一个用户。但这不是必须的,也可以为每个服务创建并配置不同的服务用户。

    在下面的示例中,用户访问OpenStack网络服务的身份验证信息配置为:

    网络服务部署在名为RegionOne的身份认证服务域中,仅在服务目录中注册公共端点接口
    
    请求时使用特定的CA SSL证书进行HTTPS连接
    
    与ironic-api服务配置相同的服务用户
    
    动态密码认证插件基于其他选项发现合适的身份认证服务API版本
    
    [neutron]
    
    # Authentication type to load (string value)
    auth_type = password
    # Authentication URL (string value)
    auth_url=https://IDENTITY_IP:5000/
    # Username (string value)
    username=ironic
    # User's password (string value)
    password=IRONIC_PASSWORD
    # Project name to scope to (string value)
    project_name=service
    # Domain ID containing project (string value)
    project_domain_id=default
    # User's domain id (string value)
    user_domain_id=default
    # PEM encoded Certificate Authority to use when verifying
    # HTTPs connections. (string value)
    cafile=/opt/stack/data/ca-bundle.pem
    # The default region_name for endpoint URL discovery. (string
    # value)
    region_name = RegionOne
    # List of interfaces, in order of preference, for endpoint
    # URL. (list value)
    valid_interfaces=public
    

    默认情况下,为了与其他服务进行通信,裸金属服务会尝试通过身份认证服务的服务目录发现该服务合适的端点。如果希望对一个特定服务使用一个不同的端点,则在裸金属服务的配置文件中通过endpoint_override选项进行指定:

    [neutron] ... endpoint_override = <NEUTRON_API_ADDRESS>
    

    5、配置允许的驱动程序和硬件类型

    通过设置enabled_hardware_types设置ironic-conductor服务允许使用的硬件类型:

    [DEFAULT] enabled_hardware_types = ipmi
    

    配置硬件接口:

    enabled_boot_interfaces = pxe enabled_deploy_interfaces = direct,iscsi enabled_inspect_interfaces = inspector enabled_management_interfaces = ipmitool enabled_power_interfaces = ipmitool
    

    配置接口默认值:

    [DEFAULT] default_deploy_interface = direct default_network_interface = neutron
    

    如果启用了任何使用Direct deploy的驱动,必须安装和配置镜像服务的Swift后端。Ceph对象网关(RADOS网关)也支持作为镜像服务的后端。

    6、重启ironic-conductor服务

    sudo systemctl restart openstack-ironic-conductor
    
  6. 配置httpd服务

    1. 创建ironic要使用的httpd的root目录并设置属主属组,目录路径要和/etc/ironic/ironic.conf中[deploy]组中http_root 配置项指定的路径要一致。

      mkdir -p /var/lib/ironic/httproot ``chown ironic.ironic /var/lib/ironic/httproot
      
    2. 安装和配置httpd服务

      1. 安装httpd服务,已有请忽略

        yum install httpd -y
        
      2. 创建/etc/httpd/conf.d/openstack-ironic-httpd.conf文件,内容如下:

        Listen 8080
        
        <VirtualHost *:8080>
            ServerName ironic.openeuler.com
        
            ErrorLog "/var/log/httpd/openstack-ironic-httpd-error_log"
            CustomLog "/var/log/httpd/openstack-ironic-httpd-access_log" "%h %l %u %t \"%r\" %>s %b"
        
            DocumentRoot "/var/lib/ironic/httproot"
            <Directory "/var/lib/ironic/httproot">
                Options Indexes FollowSymLinks
                Require all granted
            </Directory>
            LogLevel warn
            AddDefaultCharset UTF-8
            EnableSendfile on
        </VirtualHost>
        

        注意监听的端口要和/etc/ironic/ironic.conf里[deploy]选项中http_url配置项中指定的端口一致。

      3. 重启httpd服务。

        systemctl restart httpd
        
  7. deploy ramdisk镜像制作

    T版的ramdisk镜像支持通过ironic-python-agent服务或disk-image-builder工具制作,也可以使用社区最新的ironic-python-agent-builder。用户也可以自行选择其他工具制作。 若使用T版原生工具,则需要安装对应的软件包。

    yum install openstack-ironic-python-agent
    或者
    yum install diskimage-builder
    

    具体的使用方法可以参考官方文档

    这里介绍下使用ironic-python-agent-builder构建ironic使用的deploy镜像的完整过程。

    1. 安装 ironic-python-agent-builder

      1. 安装工具:

        pip install ironic-python-agent-builder
        
      2. 修改以下文件中的python解释器:

        /usr/bin/yum /usr/libexec/urlgrabber-ext-down
        
      3. 安装其它必须的工具:

        yum install git
        

        由于DIB依赖semanage命令,所以在制作镜像之前确定该命令是否可用:semanage --help,如果提示无此命令,安装即可:

        # 先查询需要安装哪个包
        [root@localhost ~]# yum provides /usr/sbin/semanage
        已加载插件:fastestmirror
        Loading mirror speeds from cached hostfile
        * base: mirror.vcu.edu
        * extras: mirror.vcu.edu
        * updates: mirror.math.princeton.edu
        policycoreutils-python-2.5-34.el7.aarch64 : SELinux policy core python utilities
        源    :base
        匹配来源:
        文件名    :/usr/sbin/semanage
        # 安装
        [root@localhost ~]# yum install policycoreutils-python
        
    2. 制作镜像

      如果是arm架构,需要添加:

      export ARCH=aarch64
      

      基本用法:

      usage: ironic-python-agent-builder [-h] [-r RELEASE] [-o OUTPUT] [-e ELEMENT]
                                          [-b BRANCH] [-v] [--extra-args EXTRA_ARGS]
                                          distribution
      
      positional arguments:
          distribution          Distribution to use
      
      optional arguments:
          -h, --help            show this help message and exit
          -r RELEASE, --release RELEASE
                              Distribution release to use
          -o OUTPUT, --output OUTPUT
                              Output base file name
          -e ELEMENT, --element ELEMENT
                              Additional DIB element to use
          -b BRANCH, --branch BRANCH
                              If set, override the branch that is used for ironic-
                              python-agent and requirements
          -v, --verbose         Enable verbose logging in diskimage-builder
          --extra-args EXTRA_ARGS
                              Extra arguments to pass to diskimage-builder
      

      举例说明:

      ironic-python-agent-builder centos -o /mnt/ironic-agent-ssh -b origin/stable/rocky
      
    3. 允许ssh登陆

      初始化环境变量,然后制作镜像:

      export DIB_DEV_USER_USERNAME=ipa \
      export DIB_DEV_USER_PWDLESS_SUDO=yes \
      export DIB_DEV_USER_PASSWORD='123'
      ironic-python-agent-builder centos -o /mnt/ironic-agent-ssh -b origin/stable/rocky -e selinux-permissive -e devuser
      
    4. 指定代码仓库

      初始化对应的环境变量,然后制作镜像:

      # 指定仓库地址以及版本
      DIB_REPOLOCATION_ironic_python_agent=git@172.20.2.149:liuzz/ironic-python-agent.git
      DIB_REPOREF_ironic_python_agent=origin/develop
      
      # 直接从gerrit上clone代码
      DIB_REPOLOCATION_ironic_python_agent=https://review.opendev.org/openstack/ironic-python-agent
      DIB_REPOREF_ironic_python_agent=refs/changes/43/701043/1
      

      参考:source-repositories

      指定仓库地址及版本验证成功。

    5. 注意 原生的openstack里的pxe配置文件的模版不支持arm64架构,需要自己对原生openstack代码进行修改:

    在T版中,社区的ironic仍然不支持arm64位的uefi pxe启动,表现为生成的grub.cfg文件(一般位于/tftpboot/下)格式不对而导致pxe启动失败

    需要用户对生成grub.cfg的代码逻辑自行修改。

    ironic向ipa发送查询命令执行状态请求的tls报错:

    T版的ipa和ironic默认都会开启tls认证的方式向对方发送请求,跟据官网的说明进行关闭即可。

    1. 修改ironic配置文件(/etc/ironic/ironic.conf)下面的配置中添加ipa-insecure=1:
    [agent]
    verify_ca = False
    
    [pxe]
    pxe_append_params = nofb nomodeset vga=normal coreos.autologin ipa-insecure=1
    
    1. ramdisk镜像中添加ipa配置文件/etc/ironic_python_agent/ironic_python_agent.conf并配置tls的配置如下:

    /etc/ironic_python_agent/ironic_python_agent.conf (需要提前创建/etc/ironic_python_agent目录)

    [DEFAULT]
    enable_auto_tls = False
    

    设置权限:

    chown -R ipa.ipa /etc/ironic_python_agent/
    
    1. 修改ipa服务的服务启动文件,添加配置文件选项

    vim usr/lib/systemd/system/ironic-python-agent.service

    ```
    [Unit]
    Description=Ironic Python Agent
    After=network-online.target
    
    [Service]
    ExecStartPre=/sbin/modprobe vfat
    ExecStart=/usr/local/bin/ironic-python-agent --config-file /etc/ironic_python_agent/ironic_python_agent.conf
    Restart=always
    RestartSec=30s
    
    [Install]
    WantedBy=multi-user.target
    ```
    

在Train中,我们还提供了ironic-inspector等服务,用户可根据自身需求安装。

Kolla 安装

Kolla为OpenStack服务提供生产环境可用的容器化部署的功能。

Kolla的安装十分简单,只需要安装对应的RPM包即可

yum install openstack-kolla openstack-kolla-ansible

安装完后,就可以使用kolla-ansible, kolla-build, kolla-genpwd, kolla-mergepwd等命令进行相关的镜像制作和容器环境部署了。

Trove 安装

Trove是OpenStack的数据库服务,如果用户使用OpenStack提供的数据库服务则推荐使用该组件。否则,可以不用安装。

  1. 设置数据库

    数据库服务在数据库中存储信息,创建一个trove用户可以访问的trove数据库,替换TROVE_DBPASSWORD为合适的密码

    mysql -u root -p
    
    MariaDB [(none)]> CREATE DATABASE trove CHARACTER SET utf8;
    MariaDB [(none)]> GRANT ALL PRIVILEGES ON trove.* TO 'trove'@'localhost' \
    IDENTIFIED BY 'TROVE_DBPASSWORD';
    MariaDB [(none)]> GRANT ALL PRIVILEGES ON trove.* TO 'trove'@'%' \
    IDENTIFIED BY 'TROVE_DBPASSWORD';
    
  2. 创建服务用户认证

    1、创建Trove服务用户

    openstack user create --domain default --password-prompt trove
    openstack role add --project service --user trove admin
    openstack service create --name trove --description "Database" database
    

    解释: TROVE_PASSWORD 替换为trove用户的密码

    2、创建Database服务访问入口

    openstack endpoint create --region RegionOne database public http://controller:8779/v1.0/%\(tenant_id\)s
    openstack endpoint create --region RegionOne database internal http://controller:8779/v1.0/%\(tenant_id\)s
    openstack endpoint create --region RegionOne database admin http://controller:8779/v1.0/%\(tenant_id\)s
    
  3. 安装和配置Trove各组件

    1、安装Trove

    yum install openstack-trove python3-troveclient
    
    1. 配置trove.conf
    vim /etc/trove/trove.conf
    
     [DEFAULT]
     log_dir = /var/log/trove
     trove_auth_url = http://controller:5000/
     nova_compute_url = http://controller:8774/v2
     cinder_url = http://controller:8776/v1
     swift_url = http://controller:8080/v1/AUTH_
     rpc_backend = rabbit
     transport_url = rabbit://openstack:RABBIT_PASS@controller:5672
     auth_strategy = keystone
     add_addresses = True
     api_paste_config = /etc/trove/api-paste.ini
     nova_proxy_admin_user = admin
     nova_proxy_admin_pass = ADMIN_PASSWORD
     nova_proxy_admin_tenant_name = service
     taskmanager_manager = trove.taskmanager.manager.Manager
     use_nova_server_config_drive = True
     # Set these if using Neutron Networking
     network_driver = trove.network.neutron.NeutronDriver
     network_label_regex = .*
    
     [database]
     connection = mysql+pymysql://trove:TROVE_DBPASSWORD@controller/trove
    
     [keystone_authtoken]
     www_authenticate_uri = http://controller:5000/
     auth_url = http://controller:5000/
     auth_type = password
     project_domain_name = default
     user_domain_name = default
     project_name = service
     username = trove
     password = TROVE_PASSWORD
    

    解释:

    • [Default]分组中nova_compute_urlcinder_url 为Nova和Cinder在Keystone中创建的endpoint
    • nova_proxy_XXX 为一个能访问Nova服务的用户信息,上例中使用admin用户为例
    • transport_urlRabbitMQ连接信息,RABBIT_PASS替换为RabbitMQ的密码
    • [database]分组中的connection 为前面在mysql中为Trove创建的数据库信息
    • Trove的用户信息中TROVE_PASSWORD替换为实际trove用户的密码
    1. 配置trove-guestagent.conf
    vim /etc/trove/trove-guestagent.conf
    
    rabbit_host = controller
    rabbit_password = RABBIT_PASS
    trove_auth_url = http://controller:5000/
    

    解释: guestagent是trove中一个独立组件,需要预先内置到Trove通过Nova创建的虚拟 机镜像中,在创建好数据库实例后,会起guestagent进程,负责通过消息队列(RabbitMQ)向Trove上 报心跳,因此需要配置RabbitMQ的用户和密码信息。 从Victoria版开始,Trove使用一个统一的镜像来跑不同类型的数据库,数据库服务运行在Guest虚拟机的Docker容器中。

    • RABBIT_PASS替换为RabbitMQ的密码
    1. 生成数据Trove数据库表
    su -s /bin/sh -c "trove-manage db_sync" trove
    
  4. 完成安装配置

    1. 配置Trove服务自启动
    systemctl enable openstack-trove-api.service \
    openstack-trove-taskmanager.service \
    openstack-trove-conductor.service 
    
    1. 启动服务
    systemctl start openstack-trove-api.service \
    openstack-trove-taskmanager.service \
    openstack-trove-conductor.service
    

Swift 安装

Swift 提供了弹性可伸缩、高可用的分布式对象存储服务,适合存储大规模非结构化数据。

  1. 创建服务凭证、API端点。

    创建服务凭证

    #创建swift用户:
    openstack user create --domain default --password-prompt swift                 
    #为swift用户添加admin角色:
    openstack role add --project service --user swift admin                        
    #创建swift服务实体:
    openstack service create --name swift --description "OpenStack Object Storage" object-store        															  
    

    创建swift API 端点:

    openstack endpoint create --region RegionOne object-store public http://controller:8080/v1/AUTH_%\(project_id\)s                            
    openstack endpoint create --region RegionOne object-store internal http://controller:8080/v1/AUTH_%\(project_id\)s                            
    openstack endpoint create --region RegionOne object-store admin http://controller:8080/v1                                                  
    
  2. 安装软件包:

    yum install openstack-swift-proxy python3-swiftclient python3-keystoneclient python3-keystonemiddleware memcached (CTL)
    
  3. 配置proxy-server相关配置

    Swift RPM包里已经包含了一个基本可用的proxy-server.conf,只需要手动修改其中的ip和swift password即可。

    注意

    注意替换password为您在身份服务中为swift用户选择的密码

  4. 安装和配置存储节点 (STG)

    安装支持的程序包:

    yum install xfsprogs rsync
    

    将/dev/vdb和/dev/vdc设备格式化为 XFS

    mkfs.xfs /dev/vdb
    mkfs.xfs /dev/vdc
    

    创建挂载点目录结构:

    mkdir -p /srv/node/vdb
    mkdir -p /srv/node/vdc
    

    找到新分区的 UUID:

    blkid
    

    编辑/etc/fstab文件并将以下内容添加到其中:

    UUID="<UUID-from-output-above>" /srv/node/vdb xfs noatime 0 2
    UUID="<UUID-from-output-above>" /srv/node/vdc xfs noatime 0 2
    

    挂载设备:

    mount /srv/node/vdb
    mount /srv/node/vdc
    

    注意

    如果用户不需要容灾功能,以上步骤只需要创建一个设备即可,同时可以跳过下面的rsync配置

    (可选)创建或编辑/etc/rsyncd.conf文件以包含以下内容:

    [DEFAULT]
    uid = swift
    gid = swift
    log file = /var/log/rsyncd.log
    pid file = /var/run/rsyncd.pid
    address = MANAGEMENT_INTERFACE_IP_ADDRESS
    
    [account]
    max connections = 2
    path = /srv/node/
    read only = False
    lock file = /var/lock/account.lock
    
    [container]
    max connections = 2
    path = /srv/node/
    read only = False
    lock file = /var/lock/container.lock
    
    [object]
    max connections = 2
    path = /srv/node/
    read only = False
    lock file = /var/lock/object.lock
    

    替换MANAGEMENT_INTERFACE_IP_ADDRESS为存储节点上管理网络的IP地址

    启动rsyncd服务并配置它在系统启动时启动:

    systemctl enable rsyncd.service
    systemctl start rsyncd.service
    
  5. 在存储节点安装和配置组件 (STG)

    安装软件包:

    yum install openstack-swift-account openstack-swift-container openstack-swift-object
    

    编辑/etc/swift目录的account-server.conf、container-server.conf和object-server.conf文件,替换bind_ip为存储节点上管理网络的IP地址。

    确保挂载点目录结构的正确所有权:

    chown -R swift:swift /srv/node
    

    创建recon目录并确保其拥有正确的所有权:

    mkdir -p /var/cache/swift
    chown -R root:swift /var/cache/swift
    chmod -R 775 /var/cache/swift
    
  6. 创建账号环 (CTL)

    切换到/etc/swift目录。

    cd /etc/swift
    

    创建基础account.builder文件:

    swift-ring-builder account.builder create 10 1 1
    

    将每个存储节点添加到环中:

    swift-ring-builder account.builder add --region 1 --zone 1 --ip STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS --port 6202  --device DEVICE_NAME --weight DEVICE_WEIGHT
    

    替换STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS为存储节点上管理网络的IP地址。替换DEVICE_NAME为同一存储节点上的存储设备名称

    ***注意 *** 对每个存储节点上的每个存储设备重复此命令

    验证戒指内容:

    swift-ring-builder account.builder
    

    重新平衡戒指:

    swift-ring-builder account.builder rebalance
    
  7. 创建容器环 (CTL)

    切换到/etc/swift目录。

    创建基础container.builder文件:

       swift-ring-builder container.builder create 10 1 1
    

    将每个存储节点添加到环中:

    swift-ring-builder container.builder \
      add --region 1 --zone 1 --ip STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS --port 6201 \
      --device DEVICE_NAME --weight 100
    

    替换STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS为存储节点上管理网络的IP地址。替换DEVICE_NAME为同一存储节点上的存储设备名称

    注意 对每个存储节点上的每个存储设备重复此命令

    验证戒指内容:

    swift-ring-builder container.builder
    

    重新平衡戒指:

    swift-ring-builder container.builder rebalance
    
  8. 创建对象环 (CTL)

    切换到/etc/swift目录。

    创建基础object.builder文件:

    ```shell
    swift-ring-builder object.builder create 10 1 1
    ```
    

    将每个存储节点添加到环中

     swift-ring-builder object.builder \
      add --region 1 --zone 1 --ip STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS --port 6200 \
      --device DEVICE_NAME --weight 100
    

    替换STORAGE_NODE_MANAGEMENT_INTERFACE_IP_ADDRESS为存储节点上管理网络的IP地址。替换DEVICE_NAME为同一存储节点上的存储设备名称

    ***注意 *** 对每个存储节点上的每个存储设备重复此命令

    验证戒指内容:

    swift-ring-builder object.builder
    

    重新平衡戒指:

    swift-ring-builder object.builder rebalance
    

    分发环配置文件:

    account.ring.gzcontainer.ring.gz以及 object.ring.gz文件复制到每个存储节点和运行代理服务的任何其他节点上的/etc/swift目录。

  9. 完成安装

    编辑/etc/swift/swift.conf文件

    [swift-hash]
    swift_hash_path_suffix = test-hash
    swift_hash_path_prefix = test-hash
    
    [storage-policy:0]
    name = Policy-0
    default = yes
    

    用唯一值替换 test-hash

    将swift.conf文件复制到/etc/swift每个存储节点和运行代理服务的任何其他节点上的目录。

    在所有节点上,确保配置目录的正确所有权:

    chown -R root:swift /etc/swift
    

    在控制器节点和运行代理服务的任何其他节点上,启动对象存储代理服务及其依赖项,并将它们配置为在系统启动时启动:

    systemctl enable openstack-swift-proxy.service memcached.service
    systemctl start openstack-swift-proxy.service memcached.service
    

    在存储节点上,启动对象存储服务并将它们配置为在系统启动时启动:

    systemctl enable openstack-swift-account.service openstack-swift-account-auditor.service openstack-swift-account-reaper.service openstack-swift-account-replicator.service
    
    systemctl start openstack-swift-account.service openstack-swift-account-auditor.service openstack-swift-account-reaper.service openstack-swift-account-replicator.service

快速安装 OpenStack

OpenStack SIG还提供了一键部署OpenStack all in one或三节点的ansible脚本,用户可以使用该脚本快速部署一套基于openEuler RPM的OpenStack环境。下面以all in one举例说明使用方法

  1. 安装OpenStack SIG工具

    pip install openstack-sig-tool
    
  2. 配置openstack yum 源

    yum install openstack-release-train
    

    注意:如果你的环境的YUM源没有启用EPOL,需要同时配置EPOL

    vi /etc/yum.repos.d/openEuler.repo
    
    [EPOL]
    name=EPOL
    baseurl=http://repo.openeuler.org/openEuler-22.03-LTS/EPOL/main/$basearch/
    enabled=1
    gpgcheck=1
    gpgkey=http://repo.openeuler.org/openEuler-22.03-LTS/OS/$basearch/RPM-GPG-KEY-openEuler
    EOF
    
  3. 刷新ansible配置

    打开/usr/local/etc/oos/inventory/all_in_one.yaml,根据当前机器环境和需求修改对应配置。内容如下

    all:
      hosts:
        controller:

      children:
        compute:
          hosts: controller
        storage:
          hosts: controller
        network:
          hosts: controller
          vars:
            test-key: test-value
        dashboard:
          hosts: controller
          vars:
            allowed_host: '*'
        kolla:
          hosts: controller
          vars:
            # We add openEuler OS support for kolla in OpenStack Queens/Rocky release
            # Set this var to true if you want to use it in Q/R
            openeuler_plugin: false
    

    关键配置

    配置项解释
    ansible_hostall in one节点IP
    ansible_ssh_private_key_fileansible脚本登录all in one节点时使用的登录秘钥
    ansible_ssh_useransible脚本登录all in one节点时使用的登录用户
    enabled_service安装服务列表,根据用户需求自行删减
    neutron_provider_interface_nameneutron L3网桥名称
    default_ext_subnet_rangeneutron私网IP段
    default_ext_subnet_gatewayneutron私网gateway
    neutron_dataplane_interface_nameneutron使用的网卡,推荐使用一张新的网卡,以免和现有网卡冲突,发现all in one主机断连的情况
    cinder_block_devicecinder使用的卷设备名
    swift_storage_devicesswift使用的卷设备名
  4. 执行安装命令

    oos env setup all_in_one
    

    该命令执行后,OpenStack all in one环境就部署成功了

    环境变量文件在当前用户的根目录下,名叫.admin-openrc

  5. 初始化tempest环境

    如果用户想使用该环境运行tempest测试的话,可以执行命令oos env init all_in_one,会自动把tempest需要的OpenStack资源自动创建好。

    命令执行成功后,在用户的根目录下会生成mytest目录,进入其中就可以执行tempest run命令了。
