# The mirror system uses the connecting IP address of the client and the
4
# update status of each mirror to pick mirrors that are updated to and
5
# geographically close to the client.  You should use this for CentOS updates

# unless you are manually picking other mirrors.

安装openstack

注意官网给出的CentOS 安装方式实测不行

1
sudo yum install -y https://rdoproject.org/repos/rdo-release.rpm
2
sudo yum update -y
3
sudo yum install -y openstack-packstack
4
sudo packstack --allinone

设置启动

1
yum install openstack-utils -y

第一种操作方式

1
openstack-service --help
2
openstack-service list
3
openstack-service restart openstack-ceilometer-polling

openstack-service 实际是一个shell脚本，底层实际调用的是centos的systemctl工具，因此我们也可以使用systemctl工具来重启服务

自启动

1
systemctl enable openstack-ceilometer-polling

使用systemctl列出所有openstack服务

1
systemctl list-unit-files --type=service --ful --no-legend --no-pager | egrep "^(openstack|neutron|quantum)" | grep -v 'neutron-.*-cleanup' | grep enable

查看指定服务当前的运行状态

1
systemctl status openstack-ceilometer-polling

重启指定服务

1
systemctl restart openstack-ceilometer-polling

停止指定服务

1
systemctl stop openstack-ceilometer-polling

卸载脚本
