Deploying A-Ops
1 Introduction to A-Ops
A-Ops is a service used to improve the overall security of hosts. It provides functions such as asset management, vulnerability management, and configuration source tracing to identify and manage information assets, monitor software vulnerabilities, and rectify system faults on hosts, ensuring stable and secure running of hosts.
The following table describes the modules related to the A-Ops service.
| Module | Description |
|---|---|
| aops-ceres | Client of the A-Ops service. Collects host data and manages other data collectors (such as gala-gopher). Responds to the commands delivered by the management center and processes the requirements and operations of the management center. |
| aops-zeus | A-Ops basic application management center, which interacts with other modules. The default port number is 11111. Provides the basic host management service externally, such as adding and deleting hosts and host groups. |
| aops-hermes | Provides a visualized operation interface for A-Ops to display data information to users, improving service usability. |
| aops-apollo | Vulnerability management module of A-Ops. The default port number is 11116. Identifies clients, and periodically obtains security notices released by the openEuler community and updates them to the vulnerability database. Detects vulnerabilities in the system and software by comparing the vulnerabilities with those in the vulnerability database. |
| aops-vulcanus | Basic tool library of A-Ops. Except aops-ceres and aops-hermes, modules must be installed and used together with this module. |
| aops-tools | Provides the basic environment deployment script and database table initialization. The script is available in the /opt/aops/scripts directory after A-Ops is installed. |
| gala-ragdoll | Configuration source tracing module of A-Ops. Uses Git to monitor and record configuration file changes. The default port number is 11114. |
| dnf-hotpatch-plugin | DNF plug-in, which allows DNF to recognize hot patch information and provides hot patch scanning and application. |
2 Environment Requirements
You are advised to use four hosts running openEuler 22.03 LTS SP3 for deployment. Use three as the server and one as the managed host managed by A-Ops. Configure the update repository (FAQs: update Repository Configuration). The deployment scheme is as follows:
- Host A: For MySQL, Redis, and Elasticsearch deployment. It provides data service support. The recommended memory is more than 8 GB.
- Host B: For the A-Ops asset management service (zeus), frontend display, and complete service function support. The recommended memory is more than 6 GB.
- Host C: For the A-Ops configuration source tracing service (gala-ragdoll) and vulnerability management. The recommended memory is 4 GB or more.
- Host D: As an A-Ops client and is used as a host managed and monitored by A-Ops. (aops-ceres can be deployed on hosts that need to be managed.)
| Host | IP Address | Module |
|---|---|---|
| Host A | 192.168.1.1 | MySQL, Elasticsearch, Redis |
| Host B | 192.168.1.2 | aops-zeus, aops-hermes, aops-diana |
| Host C | 192.168.1.3 | aops-apollo, gala-ragdoll, aops-diana |
| Host D | 192.168.1.4 | aops-ceres, dnf-hotpatch-plugin |
Before deployment, disable the firewall and SELinux on each host.
- Disable the firewall.
systemctl stop firewalld
systemctl disable firewalld
systemctl status firewalld
setenforce 0
- Disable SELinux.
# Change the status of SELinux to diabled in /etc/selinux/config.
vi /etc/selinux/config
SELINUX=disabled
# After changing the value, press ESC and enter :wq to save the modification.
Note: SELinux will be disabled after a reboot.
3. Server Deployment
3.1 Asset Management
To use the asset management function, you need to deploy the aops-zeus, aops-hermes, MySQL, and Redis services.
3.1.1 Node Information
| Host | IP Address | Module |
|---|---|---|
| Host A | 192.168.1.1 | MySQL, Redis |
| Host B | 192.168.1.2 | aops-zeus, aops-hermes |
3.1.2 Deployment Procedure
3.1.2.1 Deploying MySQL
- Install MySQL.
yum install mysql-server
- Modify the MySQL configuration file.
vim /etc/my.cnf
- Add bind-address and set it to the IP address of the local host in the mysqld section.
[mysqld]
bind-address=192.168.1.1
- Restart the MySQL service.
systemctl restart mysqld
- Set the MySQL database access permission for the root user.
$ mysql
mysql> show databases;
mysql> use mysql;
mysql> select user,host from user; -- If the value of host is localhost, only the local host can connect to the MySQL database. The external network and local software client cannot connect to the MySQL database.
+---------------+-----------+
| user | host |
+---------------+-----------+
| root | localhost |
| mysql.session | localhost |
| mysql.sys | localhost |
+---------------+-----------+
3 rows in set (0.00 sec)
mysql> update user set host = '%' where user='root'; -- Allow the access of the root user using any IP address.
mysql> flush privileges; -- Refresh the permissions.
mysql> exit
3.1.2.2 Deploying Redis
- Install Redis.
yum install redis -y
- Modify the Redis configuration file.
vim /etc/redis.conf
Bind IP addresses.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::1
#
# ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
# internet, binding to all the interfaces is dangerous and will expose the
# instance to everybody on the internet. So by default we uncomment the
# following bind directive, that will force Redis to listen only into
# the IPv4 lookback interface address (this means Redis will be able to
# accept connections only from clients running into the same computer it
# is running).
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bind 127.0.0.1 192.168.1.1# Add the actual IP address of host A.
- Start the Redis service.
systemctl start redis
3.1.2.3 Deploying Prometheus
- Install Prometheus.
yum install prometheus2 -y
- Modify the Prometheus configuration file.
vim /etc/prometheus/prometheus.yml
- Add the gala-gopher IP addresses of the managed client to the monitored targets of Prometheus.
In this document, host C is the client. Add the gala-gopher address of host C.
- Modify the targets configuration item.
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: 'prometheus'
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
- targets: ['localhost:9090', '192.168.1.3:8888'] // Add the gala-gopher IP address of host C.
Start the Prometheus service.
systemctl start prometheus
3.1.2.4 Deploying aops-zeus
- Install aops-zeus.
yum install aops-zeus -y
- Modify the configuration file.
vim /etc/aops/zeus.ini
- Change the IP address of each service in the configuration file to the actual IP address. In this document, aops-zeus is deployed on host B. Therefore, you need to set the IP address to the IP address of host B.
[zeus]
ip=192.168.1.2 // Change the IP address to the actual IP address of host B.
port=11111
[uwsgi]
wsgi-file=manage.py
daemonize=/var/log/aops/uwsgi/zeus.log
http-timeout=600
harakiri=600
processes=2 // Generate a specified number of workers or processes.
gevent=100 // Number of gevent asynchronous cores
[mysql]
ip=192.168.1.1 // Change the IP address to the actual IP address of host A.
port=3306
database_name=aops
engine_format=mysql+pymysql://@%s:%s/%s
pool_size=100
pool_recycle=7200
[agent]
default_instance_port=8888
[redis]
ip=192.168.1.1 // Change the IP address to the actual IP address of host A.
port=6379
[apollo]
ip=192.168.1.3 // Change the IP address to the actual IP address of the apollo service deployment. It is recommended that apollo and zeus be deployed separately. This section is not required if apollo is not used.
port=11116
Set the MySQL database mode to password mode. For details, see FAQs: MySQL Password Mode
- Start the aops-zeus service.
systemctl start aops-zeus
Note: Initialize the aops-zeus database before starting the service.
If the zeus service fails to be started and the error message indicates that the MySQL database cannot be connected, check if a MySQL password is set. If yes, see FAQs: MySQL Password Mode.
3.1.2.5 Initializing the aops-zeus Database
- Initialize the database.
cd /opt/aops/scripts/deploy
bash aops-basedatabase.sh init zeus
Note: If aops-tools is not installed, run the SQL script to initialize. The script path is /opt/aops/database/zeus.sql
FAQs: Nonexisting /opt/aops/scripts/deploy
3.1.2.6 Deploying aops-hermes
- Install aops-hermes.
yum install aops-hermes -y
- Modify the configuration file. Because all services are deployed on host B, set the IP address of each service accessed by aops-web to the actual IP address of host B.
vim /etc/nginx/aops-nginx.conf
Some service configurations:
As the services are deployed on host B, configure the Nginx proxy to set the services addresses to the actual IP address of host B.
# Ensure that Nginx still uses index.html as the entry when the front-end route changes.
location / {
try_files $uri $uri/ /index.html;
if (!-e $request_filename){
rewrite ^(.*)$ /index.html last;
}
}
# Change it to the actual IP address of the host where aops-zeus is deployed.
location /api/ {
proxy_pass http://192.168.1.2:11111/;
}
# Enter the IP address of gala-ragdoll. IP addresses that involve port 11114 need to be configured.
location /api/domain {
proxy_pass http://192.168.1.3:11114/;
rewrite ^/api/(.*) /$1 break;
}
# Enter the IP address of gala-apollo.
location /api/vulnerability {
proxy_pass http://192.168.1.3:11116/;
rewrite ^/api/(.*) /$1 break;
}
- Enable the aops-hermes service.
systemctl start aops-hermes
3.2 Vulnerability Management
The CVE management module is implemented based on the asset management module. Therefore, you need to deploy the module before deploying aops-apollo.
The running of the aops-apollo service requires the support of the MySQL, Elasticsearch, and Redis databases.
3.2.1 Node Information

object_file_port = 11111
[ragdoll]
port = 11114
- Start the gala-ragdoll service.
systemctl start gala-ragdoll
3.4 Exception Detection
The exception detection function is implemented based on the aops-zeus service. Therefore, you need to deploy aops-zeus and then aops-diana.
Considering distributed deployment, the aops-diana service must be deployed on both host A and host B to act as the producer and consumer in the message queue, respectively.
The running of the aops-diana service requires the support of MySQL, Elasticsearch, Kafka, and Prometheus.
3.4.1 Node Information
| Host | IP Address | Module |
|---|---|---|
| Host A | 192.168.1.1 | Kafka |
| Host B | 192.168.1.2 | aops-diana |
| Host C | 192.168.1.3 | aops-diana |
3.4.2 Deployment Procedure

# java.net.InetAddress.getCanonicalHostName() if not configured.
# FORMAT:
# listeners = listener_name://host_name:port
# EXAMPLE:
# listeners = PLAINTEXT://your.host.name:9092
listeners=PLAINTEXT://192.168.1.1:9092
- Start the Kafka service.
cd /opt/kafka/bin
nohup ./kafka-server-start.sh ../config/server.properties &
# Check all the outputs of nohup. If the IP address of host A and the Kafka startup success INFO are displayed, Kafka is started successfully.
tail -f ./nohup.out
3.4.2.2 Deploying diana
- Install aops-diana.
yum install aops-diana
Modify the configuration file.
The aops-dianas on host A and host B play different roles, which are distinguished based on the differences in the configuration file.
vim /etc/aops/diana.ini
(1) Start aops-diana on host A in executor mode. It functions as the consumer in the Kafka message queue. The configuration file to be modified is as follows:
[diana]
ip=192.168.1.3 // Change the IP address to the actual IP address of host C.
port=11112

FAQs: Nonexisting /opt/aops/scripts/deploy
3.5 Client Installation
aops-ceres functions as the client of A-Ops. It communicates with the A-Ops management center through SSH and provides functions such as host information collection and command response.
3.5.1 Node Information
| Host | IP Address | Module |
|---|---|---|
| Host D | 192.168.1.4 | aops-ceres |
3.5.2 Client Deployment
yum install aops-ceres dnf-hotpatch-plugin -y
FAQs
Max Number of Connections
When host interfaces are added in batches, due to the max number of SSH connections (MaxStartups) of the host where aops-zeus is installed, some hosts may fail to be connected. You can temporarily increase MaxStartups as required. For details, see the SSH documentation.
504 Gateway Timeout
Some HTTP interfaces may take a long time to execute, resulting in error 504 on the web client. You can reduce the probability of error 504 by adding proxy_read_timeout to the Nginx configuration or increase its value.
Firewall
If firewall cannot be disabled, open the ports involved in service deployment on the firewall. Otherwise, services may be inaccessible and A-Ops cannot be used properly.
Elasticsearch Access Denied
If Elasticsearch is deployed on multiple nodes in a distributed manner, set the cross-domain access configurations properly to enable the access of the nodes.
MySQL Password Mode
- Configure the mysql section in the service configuration.
To set the password mode for the MySQL database connection (for example, the user is root, and the password is 123456), change the value of engine_format in the [mysql] section in apollo and zeus configurations.
[mysql]
engine_format=mysql+pymysql://root:123456@%s:%s/%s
- Modify the aops-basedatabase.sh initialization script.
Modify the 145th line of aops-basedatabase.sh.
Before modification:
database = pymysql.connect(host='$mysql_ip', port=$port, database='mysql', autocommit=True,client_flag=CLIENT.MULTI_STAT EMENTS)
After modification:
database = pymysql.connect(host='$mysql_ip', port=$port, database='mysql', password='password', user='user', autocommit=True, client_flag=CLIENT.MULTI_STATEMENTS)
- Database connection error upon service startup
Modify the 178th line in /usr/bin/aops-vulcanus.
Before modification:
connect = pymysql.connect(host='$mysql_ip', port=$port, database='$aops_database')
After modification:
connect = pymysql.connect(host='$mysql_ip', port=$port, database='$aops_database', password='password', user='user')
Note: If a non-root user is used for logging in to the server, add user ="root" or a user allowed by MySQL.
