yum安装docker启动报错

从安装开始走一遍：

1、检查内核版本，必须是3.10及以上
命令：uname ‐r

[root@localhost /]# uname -r
3.10.0-327.el7.x86_64

2、安装docker
命令：yum install docker

[root@localhost /]# yum install docker

输入y确认安装

3、启动docker

（1）查看docker版本

命令：docker -v

[root@localhost /]# docker -v
Docker version 1.13.1, build 07f3374/1.13.1

 

（2）启动docker

命令：systemctl start docker

此时出现如下错误：

[root@localhost /]# systemctl start docker -l
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

（3）查看docker服务状态

命令：systemctl status docker.service -l

[root@localhost /]# systemctl status docker.service -l

Error starting daemon: SELinux is not supported with the overlay2 graph driver on this kernel. Either boot into a newer kernel or disable selinux in docker (--selinux-enabled=false)

告诉你换更新的内核或者设置：--selinux-enabled=false（英文水平差翻译没错吧.....）

配置文件在/etc/sysconfig下的docker，OPTIONS一行修改成：

OPTIONS='--selinux-enabled=false --log-driver=journald --signature-verification=false'

（4）重复启动命令成功

4、其他

（1）关闭docker

命令：systemctl stop docker

[root@localhost /]# systemctl stop docker

（2）开机启动docker

[root@localhost /]# systemctl enable docker
