OpenStack Queens Deployment Guide

OpenStack Queens Deployment Guide

Introduction to OpenStack

OpenStack is an open source cloud computing infrastructure software project developed by the community. It provides an operating platform or tool set for deploying the cloud, offering scalable and flexible cloud computing capabilities for organizations.

As an open source cloud computing management platform, OpenStack consists of several major components, such as Nova, Cinder, Neutron, Glance, Keystone, and Horizon. OpenStack supports almost all cloud environments. The project aims to provide a cloud computing management platform that is easy-to-use, scalable, unified, and standardized. OpenStack provides an infrastructure as a service (IaaS) solution that combines complementary services, each of which provides an API for integration.

The third-party oepkg Yum source certified by openEuler 20.03 LTS SP2 supports Openstack-Queens. You can configure the oepkg Yum source and deploy OpenStack based on this document.

Conventions

OpenStack supports multiple deployment modes. This document supports two deployment modes: ALL in One and Distributed. The conventions are as follows:

ALL in One mode:

Ignore all possible suffixes.

Distributed mode:

The suffix "CTL" indicates that the configuration or command applies only to the control node.
The suffix "CPT" indicates that the configuration or command applies only to compute nodes.
Otherwise, the configuration or command applies to both the controller node and compute nodes.

Note

The services involved in the above conventions are as follows:

Cinder
Nova
Neutron

Preparing the Environment

Configuring the Environment

Configure the third-party oepkg source that is certified by 20.03 LTS SP2.

cat << EOF >> /etc/yum.repos.d/OpenStack_Queens.repo
[openstack_queens]
name=OpenStack_Queens
baseurl=https://repo.oepkgs.net/openEuler/rpm/openEuler-20.03-LTS-SP2/budding-openeuler/openstack/queens/$basearch/
gpgcheck=0
enabled=1
EOF

yum clean all && yum makecache

Modify the host names and mappings.

Set the host name of each node.

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

Assume that the IP address of the controller node is 10.0.0.11 and the IP address of the compute node (if any) is 10.0.0.12, add the following information in /etc/hosts:

10.0.0.11   controller
10.0.0.12   compute

Installing the SQL Database

Run the following command to install the software package:
```
yum install mariadb mariadb-server python2-PyMySQL
```

Run the following command to create and edit the /etc/my.cnf.d/openstack.cnf file:

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

Note

Set bind-address to the management IP address of the controller node.

Start the database service and enable it to automatically start upon system boot:
```
systemctl enable mariadb.service
systemctl start mariadb.service
```
(Optional) Configure the default password for the database.
```
mysql_secure_installation
```
Note
Follow the prompts.

Installing RabbitMQ

Run the following command to install the software package:
```
yum install rabbitmq-server
```

Start the RabbitMQ service and enable it to automatically start upon system boot.

systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service

Add an OpenStack user.
```
rabbitmqctl add_user openstack RABBIT_PASS
```
Note
Replace RABBIT_PASS with the password of the OpenStack user.
Run the following command to set the permission of the openstack user so that the user can perform configuration, write, and read operations:
```
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
```

Installing Memcached

Run the following command to install the target software package:
```
yum install memcached python2-memcached
```

Edit the /etc/sysconfig/memcached file.

vim /etc/sysconfig/memcached

OPTIONS="-l 127.0.0.1,::1,controller"

Run the following command to start the Memcached service and enable it to automatically start upon system boot:
```
systemctl enable memcached.service
systemctl start memcached.service
```
After the service is started, you can run the memcached-tool controller stats command to ensure that the service is available. Replace controller with the management IP address of the controller node.

Installing OpenStack

Installing Keystone

Create the keystone database and grant access to the keystone database.

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';
MariaDB [(none)]> exit

Note

Replace KEYSTONE_DBPASS with the password of the keystone database.

Install the software package.

yum install openstack-keystone httpd python2-mod_wsgi

Configure the Keystone.
```
vim /etc/keystone/keystone.conf

[database]
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone

[token]
provider = fernet
```
Note
In the [database] section, configure the database entry.
In the [token] section, configure the token provider.
Notes:
Replace KEYSTONE_DBPASS with the password of the keystone database.

Synchronize the database.

su -s /bin/sh -c "keystone-manage db_sync" keystone

Initialize the Fernet keystore.

keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

In the [default] section, enable the compute and metadata APIs, configure the RabbitMQ message queue entrance, my_ip, and enable the network service Neutron.

In the [api_database] and [database] sections, configure the database entry.

In the [api] and [keystone_authtoken] sections, configure the identity service entry.

In the [vnc] section, enable and configure the entry for the remote console.

In the [glance] section, configure the API address for the image service.

In the [oslo_concurrency] section, configure the lock path.

In the [placement] section, configure the entry of the Placement service.

Note

Replace RABBIT_PASS with the password of the openstack user in RabbitMQ.

Set my_ip to the management IP address of the controller node.

Replace NOVA_DBPASS with the password of the nova database.

Replace NOVA_PASS with the password of the nova user.

Replace PLACEMENT_PASS with the password of the placement user.

Replace NEUTRON_PASS with the password of the neutron user.

Replace METADATA_SECRET with a proper metadata agent secret.

Exception

Manually add the Placement API access configuration.

vim /etc/httpd/conf.d/00-nova-placement-api.conf                                               (CTL)

      Require all granted
   </IfVersion>
   <IfVersion < 2.4>
      Order allow,deny
      Allow from all
   </IfVersion>
</Directory>

Restart the httpd service.

systemctl restart httpd                                                                        (CTL)

Check whether VM hardware acceleration (x86 architecture) is supported:

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

If the returned value is 0, hardware acceleration is not supported. You need to configure libvirt to use QEMU instead of KVM.

vim /etc/nova/nova.conf                                                                        (CPT)

[libvirt]
virt_type = qemu

If the returned value is 1 or a larger value, hardware acceleration is supported, and no extra configuration is required.

Note

If the ARM64 structure is used, run the following command:

mkdir -p /usr/share/AAVMF

Installing Ironic

Ironic is a bare metal service of OpenStack. You are advised to use Ironic if you need to deploy a bare metal server. Otherwise, the installation is not required.

Set the database.

The bare metal service stores information in the database. Create an Ironic database that can be accessed by the ironic user and replace Ironic_DBPASSWORD with a proper password.

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';

Create the service user and perform verification.

1. Create the bare metal service users.

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

openstack service create --name ironic-inspector --description     "Ironic inspector baremetal provisioning service" baremetal-introspection
openstack user create --password IRONIC_INSPECTOR_PASSWORD --email ironic_inspector@example.com ironic_inspector
openstack role add --project service --user ironic-inspector admin

2. Create the bare metal service access portals.

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
openstack endpoint create --region RegionOne baremetal-introspection internal http://172.20.19.13:5050/v1
openstack endpoint create --region RegionOne baremetal-introspection public http://172.20.19.13:5050/v1
openstack endpoint create --region RegionOne baremetal-introspection admin http://172.20.19.13:5050/v1

Configuring the ironic-api Service

Configuration file path: /etc/ironic/ironic.conf

1. Set connection to the database location, as shown in the following example. Replace IRONIC_DBPASSWORD with the password of the ironic user and DB_IP with the IP address of the database server.

[database]

# The SQLAlchemy connection string used to connect to the
# database (string value)

connection = mysql+pymysql://ironic:IRONIC_DBPASSWORD@DB_IP/ironic

2. Configure the ironic-api service to use the RabbitMQ message broker and replace RPC_* with the address and credential of RabbitMQ.

[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/

You can also use JSON-RPC to replace RabbitMQ.

3. Configure the credential for the ironic-api service to use the identity service. Replace PUBLIC_IDENTITY_IP with the public IP address of the server of the identity service, and replace PRIVATE_IDENTITY_IP with the private IP address of the identity service server. Replace Ironic_PASSWORD with the password of user ironic.

[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

[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. Configure the database location. The configuration of ironic-conductor must be the same as that of ironic-api. Replace IRONIC_DBPASSWORD with the password of the ironic user and DB_IP with the IP address of the database server.

[database]

# The SQLAlchemy connection string to use to connect to the
# database. (string value)

connection = mysql+pymysql://ironic:IRONIC_DBPASSWORD@DB_IP/ironic

3. Configure the ironic-api service to use the RabbitMQ. The configuration of ironic-conductor service must be the same as that of ironic-api. Replace RPC_* with the address and credential of RabbitMQ.

[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/

You can also use JSON-RPC to replace RabbitMQ.

4. Configure credentials to access other OpenStack services.

To communicate with other OpenStack services, the service user needs to use the OpenStack Identity service for authentication when the bare metal service requests other services. The credentials for these users must be configured in each configuration file associated with the respective service.

[neutron] - Access OpenStack network service.
[glance] - Access the OpenStack image service.
[swift] - Access the OpenStack object storage service.
[cinder] Access the OpenStack block storage service.
[inspector] - Access the OpenStack inspection service of the bare metal service.
[service_catalog] - A special item used to store the credentials used by the bare metal service to discover its own API URL endpoints registered in the OpenStack identity service catalog.

For simplicity, you can use the same service user for all services. For backward compatibility, this user must be the same as that configured in [keystone_authtoken] of the ironic-api service. This is not mandatory. You can create and configure different service users for each service.

In the following example, the configuration for the authentication information for users to access the OpenStack network service is:

Network services are deployed in the identity service domain named "RegionOne". Only public endpoint APIs are registered in the service catalog.

A specific CA SSL certificate is used for HTTPS connection when requested.

The same service user with ironic-api service is configured.

The dynamic password authentication plug-in discovers the appropriate version of the identity service API based on other options.

[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

By default, to communicate with other services, the bare metal service attempts to discover the appropriate endpoints of the service through the service catalog of the identity service. If you want to use a different endpoint for a specific service, specify the endpoint_override option in the bare metal service configuration file.

[neutron] ... endpoint_override = <NEUTRON_API_ADDRESS>

5. Configure allowed drivers and hardware types.

Configure enabled_hardware_types to set the hardware types allowed by the ironic-conductor service.

[DEFAULT] enabled_hardware_types = ipmi

Configure the hardware API.

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

Configure API default values.

[DEFAULT] default_deploy_interface = direct default_network_interface = neutron

If any driver that uses Direct Deploy is enabled, you must install and configure the Swift backend of the . The Ceph object gateway (RADOS gateway) can also be used as a backend for the image service.

6. Restart the ironic-conductor service.

sudo systemctl restart openstack-ironic-conductor

Configure the ironic-conductor service.

Configuration file path: /etc/ironic-inspector/inspector.conf

1. Create a database.

# mysql -u root -p

MariaDB [(none)]> CREATE DATABASE ironic_inspector CHARACTER SET utf8;

MariaDB [(none)]> GRANT ALL PRIVILEGES ON ironic_inspector.* TO 'ironic_inspector'@'localhost' \     IDENTIFIED BY 'IRONIC_INSPECTOR_DBPASSWORD';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON ironic_inspector.* TO 'ironic_inspector'@'%' \
IDENTIFIED BY 'IRONIC_INSPECTOR_DBPASSWORD';

2. Set connection to the database location, as shown in the following example. Replace IRONIC_INSPECTOR_DBPASSWORD with the password of the ironic_inspector user and DB_IP with the IP address of the database server.

[database]
backend = sqlalchemy
connection = mysql+pymysql://ironic_inspector:IRONIC_INSPECTOR_DBPASSWORD@DB_IP/ironic_inspector

3. Configure the communication address of the message queue.

[DEFAULT] transport_url = rabbit://RPC_USER:RPC_PASSWORD@RPC_HOST:RPC_PORT/

4. Configure Keystone authentication.

[DEFAULT]

auth_strategy = keystone

[ironic]

api_endpoint = http://IRONIC_API_HOST_ADDRRESS:6385
auth_type = password
auth_url = http://PUBLIC_IDENTITY_IP:5000
auth_strategy = keystone
ironic_url = http://IRONIC_API_HOST_ADDRRESS:6385
os_region = RegionOne
project_name = service
project_domain_name = Default
user_domain_name = Default
username = IRONIC_SERVICE_USER_NAME
password = IRONIC_SERVICE_USER_PASSWORD

5. Configure the ironic inspector Dnsmasq service.

#Configuration file path: /etc/ironic-inspector/dnsmasq.conf
port=0
interface=enp3s0                         #Replace it with the actual listening network API.
dhcp-range=172.20.19.100,172.20.19.110   #Replace it with the actual DHCP address range.
bind-interfaces
enable-tftp

dhcp-match=set:efi,option:client-arch,7
dhcp-match=set:efi,option:client-arch,9
dhcp-match=aarch64, option:client-arch,11
dhcp-boot=tag:aarch64,grubaa64.efi
dhcp-boot=tag:!aarch64,tag:efi,grubx64.efi
dhcp-boot=tag:!aarch64,tag:!efi,pxelinux.0

tftp-root=/tftpboot                       #Replace it with the actual tftpboot directory.
log-facility=/var/log/dnsmasq.log

6. Enable the services.

systemctl enable --now openstack-ironic-inspector.service
systemctl enable --now openstack-ironic-inspector-dnsmasq.service

Create a deploy ramdisk image.

RAMDisk images of OpenStack Queens can be created using the ironic-python-agent service or disk-image-builder tool, or the latest ironic-python-agent-builder in the community. You can also use other tools. If the native tool of OpenStack Queens RAMDisk is used, you need to install the corresponding software package.

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

For details, see the official document.

This section describes how to use ironic-python-agent-builder to build the deploy image used by Ironic.

Installing Kolla

Kolla provides container-based deployment for OpenStack services in the production environment. The Kolla and Kolla-ansible services are introduced in openEuler 20.03 LTS SP2.

The installation of Kolla is simple. You only need to install the corresponding RPM package.

yum install openstack-kolla openstack-kolla-ansible

After the installation, you can use commands including kolla-ansible, kolla-build, kolla-genpwd, and kolla-mergepwd.

Installing Trove

Trove is a database service provided by OpenStack. You are advised to use Trove if you use the database service provided by OpenStack. Otherwise, the installation is not required.

Set the database.

The database service stores information in the database. Create a trove user to access the trove database. Replace TROVE_DBPASSWORD with a proper password.

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';

Create the service user and perform verification.

1. Create a Trove service user.

openstack user create --password TROVE_PASSWORD \
                      --email trove@example.com trove
openstack role add --project service --user trove admin
openstack service create --name trove
                         --description "Database service" database

Note: Replace TROVE_PASSWORD with the password of the trove user.

2. Create a database service access portal.

openstack endpoint create --region RegionOne database public http://$TROVE_NODE:8779/v1.0/%\(tenant_id\)s
openstack endpoint create --region RegionOne database internal http://$TROVE_NODE:8779/v1.0/%\(tenant_id\)s
openstack endpoint create --region RegionOne database admin http://$TROVE_NODE:8779/v1.0/%\(tenant_id\)s

Note: Replace $TROVE_NODE with the API service deployment node of the Trove.

Install and configure Trove components.
1. Install the Trove package.

yum install openstack-trove python-troveclient

Configure trove.conf.

vim /etc/trove/trove.conf

[DEFAULT]
bind_host=TROVE_NODE_IP
log_dir = /var/log/trove

auth_strategy = keystone
# Config option for showing the IP address that nova doles out
add_addresses = True
network_label_regex = ^NETWORK_LABEL$
api_paste_config = /etc/trove/api-paste.ini

trove_auth_url = http://controller:35357/v3/
nova_compute_url = http://controller:8774/v2
cinder_url = http://controller:8776/v1

nova_proxy_admin_user = admin
nova_proxy_admin_pass = ADMIN_PASS
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=.*


transport_url = rabbit://openstack:RABBIT_PASS@controller:5672/

[database]
connection = mysql+pymysql://trove:TROVE_DBPASS@controller/trove

[keystone_authtoken]
www_authenticate_uri = http://controller:5000/v3/
auth_url=http://controller:35357/v3/
#auth_uri = http://controller/identity
#auth_url = http://controller/identity_admin
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = trove
password = TROVE_PASS

Note:

Set bind_host in the [Default] section to the IP address of the Trove node in the group.
nova_compute_url and cinder_url are endpoints created in Keystone for Nova and Cinder.
nova_proxy_XXX shows the information about a user who can access the Nova service. In the preceding example, the admin user is used as an example.
transport_url is the connection information of RabbitMQ. Replace RABBIT_PASS with the RabbitMQ password.
connection in the [database] section is the information about the database created for Trove in the MySQL.
Replace TROVE_PASS with the actual password of the trove user.

Configure trove-taskmanager.conf.

vim /etc/trove/trove-taskmanager.conf

[DEFAULT]
log_dir = /var/log/trove
trove_auth_url = http://controller/identity/v2.0
nova_compute_url = http://controller:8774/v2
cinder_url = http://controller:8776/v1
transport_url = rabbit://openstack:RABBIT_PASS@controller:5672/

[database]
connection = mysql+pymysql://trove:TROVE_DBPASS@controller/trove

Note: Refer to the configuration of trove.conf.

Configure trove-conductor.conf.

vim /etc/trove/trove-conductor.conf

[DEFAULT]
log_dir = /var/log/trove
trove_auth_url = http://controller/identity/v2.0
nova_compute_url = http://controller:8774/v2
cinder_url = http://controller:8776/v1
transport_url = rabbit://openstack:RABBIT_PASS@controller:5672/

[database]
connection = mysql+pymysql://trove:trove@controller/trove

Note: Refer to the configuration of trove.conf.

Configure trove-guestagent.conf.

vim /etc/trove/trove-guestagent.conf
[DEFAULT]
rabbit_host = controller
rabbit_password = RABBIT_PASS
nova_proxy_admin_user = admin
nova_proxy_admin_pass = ADMIN_PASS
nova_proxy_admin_tenant_name = service
trove_auth_url = http://controller/identity_admin/v2.0

Note: guestagent is an independent component of Trove and needs to be built into the VM image created by the Trove through Nova. After a database instance is created, the guest agent process is started to report heartbeat messages to the Trove through the message queue (RabbitMQ). Therefore, you need to configure the RabbitMQ user name and password.

Generate the Trove database table.

su -s /bin/sh -c "trove-manage db_sync" trove

Complete the installation and configuration.

Configure the automatic startup of the Trove service.

systemctl enable openstack-trove-api.service \
openstack-trove-taskmanager.service \
openstack-trove-conductor.service

Start the service.

systemctl start openstack-trove-api.service \
openstack-trove-taskmanager.service \
openstack-trove-conductor.service
