无法在计算节点上启动openstack-nova-compute.service

Question

我想开始openstack-nova-compute.service：

systemctl restart openstack-nova-compute.service 

没有打印信息（我认为它开始成功，但我错了）

我使用以下命令检查openstack-nova-compute.service状态：

[root@ha-node1 ~]# systemctl status openstack-nova-compute.service
● openstack-nova-compute.service - OpenStack Nova Compute Server
   Loaded: loaded (/usr/lib/systemd/system/openstack-nova-compute.service; disabled; vendor preset: disabled)
   Active: activating (start) since Thu 2017-08-03 00:23:52 CST; 6s ago
 Main PID: 103174 (nova-compute)
   CGroup: /system.slice/openstack-nova-compute.service
           └─103174 /usr/bin/python2 /usr/bin/nova-compute

你看它没有运行。

在/var/log/nova/nova-compute.log：
