Docker服务的重启服务命令详解(systemctl restart docker)

Docker服务的重启服务命令

重启Docker服务

#重启docker服务:
systemctl restart docker

非root用户使用

#重启docker服务:
sudo systemctl restart docker

在使用systemctl start docker启动失败时，使用systemctl status docker.service

报告如下：

root@localhost ~]# systemctl status docker.service

查资料得知：

这里是linux的内核中的SELinux不支持 overlay2 graph driver 

解决方法有两个

要么启动一个新内核，要么就在docker里禁用selinux，–selinux-enabled=false

vi /etc/sysconfig/docker

然后systemctl start docker，问题解决！

总结

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
