OpenStack双节点部署—M ceilometer（监测服务）

一、安装、配置并使用mongodb 数据库

Controller节点

1.安装配置mongodb

#  yum install -y mongodb-server mongodb

# vi /etc/mongod.conf
bind_ip = 192.168.100.10
smallfiles = true

2.启动mongodb 数据库并设置开机自启

# systemctl enable mongod.service
# systemctl start mongod.service

3.创建ceilometer非关系数据库

# mongo --host controller --eval '
  db = db.getSiblingDB("ceilometer");
  db.createUser({user: "ceilometer",
  pwd: "123456",
  roles: [ "readWrite", "dbAdmin" ]})'

二、创建服务凭证和API端点

Controller节点

1.创建服务凭证

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

2.创建API端点

# openstack endpoint create --region RegionOne \
   metering public http://controller:8777
# openstack endpoint create --region RegionOne \
   metering internal http://controller:8777
#  openstack endpoint create --region RegionOne \
   metering admin http://controller:8777

三、安装并配置监测服务

1.安装并配置ceilometer

Controller节点

1）安装ceilometer相关包

# yum install -y openstack-ceilometer-api \
openstack-ceilometer-collector openstack-ceilometer-notification \
   openstack-ceilometer-central python-ceilometerclient

2）配置/etc/ceilometer/ceilometer.conf文件

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

[database]
connection = mongodb://ceilometer:123456@controller:27017/ceilometer

[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 = ceilometer
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 = ceilometer
password = 123456
interface = internalURL
region_name = RegionOne

3）启动ceilometer服务并设置开机自启

# systemctl enable openstack-ceilometer-api.service \
   openstack-ceilometer-notification.service \
   openstack-ceilometer-central.service \
   openstack-ceilometer-collector.service

# systemctl start openstack-ceilometer-api.service \
   openstack-ceilometer-notification.service \
   openstack-ceilometer-central.service \
   openstack-ceilometer-collector.service

2.启用图像服务表

1）配置/etc/glance/glance-api.conf文件

# vi /etc/glance/glance-api.conf
[DEFAULT]
rpc_backend = rabbit

[oslo_messaging_notifications]
driver = messagingv2

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

2）重启镜像服务

# systemctl restart openstack-glance-api.service openstack-glance-registry.service

3.启用计算服务表

Compute节点

1）安装ceilometer相关包

# yum install -y openstack-ceilometer-compute python-ceilometerclient python-pecan

2）配置/etc/ceilometer/ceilometer.conf文件

# vi /etc/ceilometer/ceilometer.conf
[DEFAULT]
rpc_backend = rabbit
auth_strategy = keystone
instance_usage_audit = True
instance_usage_audit_period = hour
notify_on_state_change = vm_and_task_state
notification_driver = messagingv2

[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_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 = ceilometer
password = 123456
interface = internalURL
region_name = RegionOne

[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 = ceilometer
password = 123456

3）启动ceilometer服务并设置开机自启

# systemctl enable openstack-ceilometer-compute.service
# systemctl start openstack-ceilometer-compute.service
# systemctl restart openstack-nova-compute.service

4.启用块存储表

Controller节点、Compute节点

1.编辑/etc/cinder/cinder.conf文件

# vi /etc/cinder/cinder.conf
[oslo_messaging_notifications]
driver = messagingv2

2.重启cinder服务

# systemctl restart openstack-cinder-api.service openstack-cinder-scheduler.service
# systemctl restart openstack-cinder-volume.service

5.启用对象存储表

Controller节点

1）创建ResellerAdmin角色，并加入ceilometer用户

# . /root/admin-openrc
# openstack role create ResellerAdmin
# openstack role add --project service --user ceilometer ResellerAdmin

2）安装相关包

# yum install -y python-ceilometermiddleware

3）编辑/etc/swift/proxy-server.conf文件

# vi /etc/swift/proxy-server.conf
在[filter:keystoneauth]选项添加admin, user, ResellerAdmin
[filter:keystoneauth]
operator_roles = admin, user, ResellerAdmin

在[pipeline:main]选项添加ceilometer
[pipeline:main]
pipeline = ceilometer catch_errors gatekeeper healthcheck proxy-logging cache container_sync bulk ratelimit authtoken keystoneauth container-quotas account-quotas slo dlo versioned_writes proxy-logging proxy-server

添加[filter:ceilometer]选项
[filter:ceilometer]
paste.filter_factory = ceilometermiddleware.swift:filter_factory
control_exchange = swift
url = rabbit://openstack:123456@controller:5672/
driver = messagingv2
topic = notifications
log_level = WARN

4）重新启动对象存储代理服务

# systemctl restart openstack-swift-proxy.service
