安装Aodh

Aodh是提供监控告警的服务。请在控制节点安装Aodh。

1. 创建数据库。
   1. 以root用户登录数据库。

      mysql -u root -p

   2. 在数据库中，创建Aodh数据库并授权。

      CREATE DATABASE aodh; 
      GRANT ALL PRIVILEGES ON aodh.* TO 'aodh'@'localhost' IDENTIFIED BY 'AODH_DBPASS'; 
      GRANT ALL PRIVILEGES ON aodh.* TO 'aodh'@'%' IDENTIFIED BY 'AODH_DBPASS'; 

      

      将AODH_DBPASS替换为aodh数据库用户的密码，请根据实际情况进行设置。密码中请勿包含字符“#@$”，支持特殊字符“&=- _ . + ! * ()”

   3. 退出数据库。

      exit

2. 创建对应Keystone资源对象。

   openstack user create --domain default --password-prompt aodh 
   openstack role add --project service --user aodh admin 
   openstack service create --name aodh --description "Telemetry" alarming 
   openstack endpoint create --region RegionOne alarming public http://controller:8042 
   openstack endpoint create --region RegionOne alarming internal http://controller:8042 
   openstack endpoint create --region RegionOne alarming admin http://controller:8042

   

   密码中请勿包含字符“#@$”，支持特殊字符“&=- _ . + ! * ()”

3. 安装Aodh。

   yum install openstack-aodh-api openstack-aodh-evaluator openstack-aodh-notifier openstack-aodh-listener openstack-aodh-expirer python3-aodhclient

4. 修改配置文件。
   1. 打开文件。

      vi  /etc/aodh/aodh.conf

   2. 按“i”进入编辑模式，修改如下内容。

      [database]
      connection = mysql+pymysql://aodh:AODH_DBPASS@controller/aodh
       
      [DEFAULT] 
      transport_url = rabbit://openstack:RABBIT_PASSWORD@controller
      auth_strategy = keystone 
       
      [keystone_authtoken] 
      www_authenticate_uri = http://controller:5000 
      auth_url = http://controller:5000 
      memcached_servers = controller:11211 
      auth_type = password 
      project_domain_id = default 
      user_domain_id = default 
      project_name = service 
      username = aodh 
      password = AODH_PASSWORD
       
      [service_credentials] 
      auth_type = password 
      auth_url = http://controller:5000/v3 
      project_domain_id = default 
      user_domain_id = default 
      project_name = service 
      username = aodh 
      password = AODH_PASSWORD
      interface = internalURL 
      region_name = RegionOne

      

      将AODH_DBPASS替换为Aodh数据库密码，将RABBIT_PASSWORD替换为OpenStack RABBITMQ密码，将AODH_PASSWORD替换为Aodh用户密码，请根据实际需求进行设置。密码中请勿包含字符“#@$”，支持特殊字符“&=- _ . + ! * ()”。

   3. 按“Esc”键退出编辑模式，输入:wq!，按“Enter”键保存并退出文件。
5. 初始化数据库。

   aodh-dbsync

6. 启动Aodh服务。

   systemctl enable openstack-aodh-api.service openstack-aodh-evaluator.service openstack-aodh-notifier.service openstack-aodh-listener.service 
   systemctl start openstack-aodh-api.service openstack-aodh-evaluator.service openstack-aodh-notifier.service openstack-aodh-listener.service
