实际生产环境是juno版本，参考了官网的文档《openstack-ops-manual》，文档上是先servcie stop，后start，挺麻烦的，直接restart，整理后的重启命令如下：

1	service rabbitmq-server restart

补充：rabbitmq服务状态查看命令：rabbitmqctl status

    OpenStack Identity:

1	service openstack-keystone restart

    OpenStack Image Service:

1 2	service openstack-glance-api restart   service openstack-glance-registry restart

    OpenStack Compute:

1 2 3 4 5 6

# service openstack-nova-api restart # service openstack-nova-scheduler restart # service openstack-nova-conductor restart # service openstack-nova-cert restart # service openstack-nova-consoleauth restart # service openstack-nova-novncproxy restart

    OpenStack Block Storage:

1 2	# service openstack-cinder-api restart # service openstack-cinder-scheduler restart

    Restart compute services:

1 2 3

# service openstack-nova-compute restart # service openstack-nova-network restart # service openstack-nova-metadata-api restart

 Restart ceilometer services:

1	# service ceilometer-api restart

    neutron部分参照下面列出的服务名：

[root@node-9 ~]# chkconfig --list|grep neutron

neutron-dhcp-agent0:off1:off2:on3:on4:on5:on6:off

neutron-l3-agent0:off1:off2:on3:on4:on5:on6:off

neutron-lbaas-agent0:off1:off2:off3:off4:off5:off6:off

neutron-metadata-agent0:off1:off2:on3:on4:on5:on6:off

neutron-openvswitch-agent0:off1:off2:on3:on4:on5:on6:off

neutron-ovs-cleanup0:off1:off2:on3:on4:on5:on6:off

neutron-server 0:off1:off2:on3:on4:on5:on6:off

    具体命令就是service + 上面的服务名 + restart ，这里就不重复了。

    最后，可以通过下面的命令检查一下是不是有遗漏的服务没有重启，一般来说，上面的重启命令应该就足够了，有一些不是关键进程，可以不重启，具体需要看你的需求了。

[root@node-9 ~]# chkconfig --list|grep openstack

openstack-cinder-api0:off1:off2:on3:on4:on5:on6:off
