DOCKER启动失败

错误消息

 [root@localhost docker]# yum install docker......[root@localhost docker]# systemctl start dockerFailed to start docker.service: Unit is masked.

错误原因

 # /var/log/messagesMay 12 18:14:04 localhost systemd: Started Session 11 of user root.May 12 18:14:04 localhost systemd-logind: New session 11 of user root.

怀疑是主机名称问题
查看主机名称为 localhost4.localdomain4

[root@localhost system]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
[root@localhost system]# cat /etc/hostname 
localhost.localdomain

解决办法

重新设置主机名称 => test-1

[root@localhost system]# hostnamectl set-hostname "test-1"
[root@localhost system]# 
[root@localhost system]# 
[root@localhost system]# 
[root@localhost system]# hostname
test-1
[root@localhost system]# cat /etc/hostname
test-1

重新连接虚拟机实例
