Openstack I版 结合 Ceph 分布式存储 部署安装(十)
配置Ceilometer Server控制服务
Ceilometer项目创建时最初的目的是实现一个能为计费系统采集数据的框架。社区推动Ceilometer成为OpenStack里数据采集（监控数据、计费数据）的基础设施，采集到的数据提供给监控、计费、面板等项目使用
在controller控制节点上安装组件
yum install openstack-ceilometer-api openstack-ceilometer-collector \
openstack-ceilometer-notification openstack-ceilometer-central \
openstack-ceilometer-alarm python-ceilometerclient -y
yum install mongodb-server mongodb -y
vi /etc/mongodb.conf
bind_ip = 0.0.0.0
启动mongodb服务
service mongod start
chkconfig mongod on
mongo --host controller --eval '
db = db.getSiblingDB("ceilometer");
db.addUser({user: "ceilometer",
pwd: "CEILOMETER_DBPASS",
roles: [ "readWrite", "dbAdmin" ]})'
openssl rand -hex 10

创建角色
keystone user-create --name=ceilometer --pass=CEILOMETER_PASS --email=ceilometer@example.com
