OpenStack双节点部署—M aodh（报警服务）

一、数据库配置

# mysql -uroot -p123456
MariaDB [(none)]> CREATE DATABASE aodh;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON aodh.* TO 'aodh'@'localhost' IDENTIFIED BY '123456';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON aodh.* TO 'aodh'@'%' IDENTIFIED BY '123456';
MariaDB [(none)]> exit

二、创建服务凭证和API端点

1.创建服务凭证

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

2.API端点

# 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

三、安装并配置aodh服务

1.安装aodh相关包

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

2.编辑/etc/aodh/aodh.conf文件

# vi /etc/aodh/aodh.conf
[DEFAULT]
rpc_backend = rabbit
auth_strategy = keystone

[database]
connection = mysql+pymysql://aodh:123456@controller/aodh

[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = 123456

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = aodh
password = 123456

[service_credentials]
auth_type = password
auth_url = http://controller:5000/v3
project_domain_name = default
user_domain_name = default
project_name = service
username = aodh
password = 123456
interface = internalURL
region_name = RegionOne

3.同步数据库

# su -s /bin/sh -c "aodh-dbsync" aodh

4.启动aodh服务并设置开机自启

# 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

四、验证ceilometer服务

# . /root/admin-openrc
# ceilometer meter-list

# IMAGE_ID=$(glance image-list | grep 'cirros' | awk '{ print $2 }')
# glance image-download $IMAGE_ID > /tmp/cirros.img

# ceilometer meter-list
# ceilometer statistics -m image.download -p 60
# rm /tmp/cirros.img
rm: remove regular file ‘/tmp/cirros.img’? y
