下列操作在控制节点上进行：

1 准备条件

在配置OpenStack Telemetry服务之前，你必须创建数据库、服务凭证和API端点。

1.1 数据库

以root用户连接数据库服务器，创建glance数据库，并赋予适当的权限：

$ mysql -u root -pMariaDB [(none)]> CREATE DATABASE aodh;MariaDB [(none)]> GRANT ALL PRIVILEGES ON aodh.* TO 'aodh'@'controller3' \  IDENTIFIED BY 'pass123456';MariaDB [(none)]> GRANT ALL PRIVILEGES ON aodh.* TO 'aodh'@'%' \  IDENTIFIED BY 'pass123456';MariaDB [(none)]> exit

1.2 服务凭证

创建aodh服务实体：

$ . admin-openrc$ openstack user create --domain default \  --password-prompt aodhUser Password:Repeat User Password:$ openstack role add --project service --user aodh admin$ openstack service create --name aodh \  --description "Telemetry" alarming

1.3 API 端点

创建网络服务API端点：

$ openstack endpoint create --region RegionOne \  alarming public http://controller3:8042$ openstack endpoint create --region RegionOne \  alarming internal http://controller3:8042$ openstack endpoint create --region RegionOne \  alarming admin http://controller3:8042

2 安装配置组件

2.1 安装包

# yum install -y openstack-aodh-api \  openstack-aodh-evaluator openstack-aodh-notifier \  openstack-aodh-listener openstack-aodh-expirer \  python-aodhclient

2.2 配置

编辑配置文件/etc/aodh/aodh.conf：

[DEFAULT]...transport_url = rabbit://openstack:pass123456@controller3auth_strategy = keystone[database]...connection = mysql+pymysql://aodh:pass123456@controller3/aodh[keystone_authtoken]...auth_uri = http://controller3:5000auth_url = http://controller3:35357memcached_servers = controller3:11211auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = aodhpassword = pass123456[service_credentials]...auth_type = passwordauth_url = http://controller3:5000/v3project_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = aodhpassword = pass123456interface = internalURLregion_name = RegionOne

2.3 运行初始化数据库脚本

aodh-dbsync

3 完成安装

启动Telemetry Alarming服务，并配置随系统启动：

# 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
