openstack 整个系统重启命令如下： openstack-service  restart

当前场景是packstack 安装后重启命令不存在，openstack-service 不存在

解决方法：

使用YUM的方式安装

yum install openstack-utils -y

配置合适的yum源，比如使用

yum install https://buildlogs.centos.org/centos/7/cloud/x86_64/openstack-liberty/centos-release-openstack-liberty-1-3.el7.noarch.rpm

[root@controller yum.repos.d]# openstack-service  restart

[root@controller yum.repos.d]# openstack-service  status
