> 最近在一台新的虚拟机CentOS7上安装docker后，启动失败，控制台报错：`Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.`

按照提示,输入代码查询详细信息:

systemctl status docker.service

控制台显示：

    Jan 21 03:19:27 localhost.localdomain systemd[1]: docker.service failed.

注意到这一行`Error starting daemon: SELinux is not supported with the overlay2 graph driver on this kernel. Eit...d=false)`,大致意思好像是`SELinux不支持这个内核上的OrthALA2图形驱动程序`

解决方法:

vi /etc/sysconfig/docker

打开后的文件:

# /etc/sysconfig/docker
    
    # Modify these options if you want to change the way the docker daemon runs
    OPTIONS='--selinux-enabled --log-driver=journald --signature-verification=false'
    if [ -z "${DOCKER_CERT_PATH}" ]; then
        DOCKER_CERT_PATH=/etc/docker
    fi

把`--selinux-enabled`改成false,即`--selinux-enabled=false`:  
如下:

# /etc/sysconfig/docker
    
    # Modify these options if you want to change the way the docker daemon runs
    OPTIONS='--selinux-enabled=false --log-driver=journald --signature-verification=false'
    if [ -z "${DOCKER_CERT_PATH}" ]; then
        DOCKER_CERT_PATH=/etc/docker
    fi

重启docker

systemctl restart docker

启动成功.
