通过journalctl -xe查看日志记录，有如下提示

**原因分析：**  
根据报错信息“Error starting daemon: SELinux is not supported with the overlay2 graph driver on this kernel. Either boot into a newer kernel or disabl…nabled=false)”的提示，这台机器的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配置文件里面里禁用selinux，–selinux-enabled=false

**解决方法**：  
没有启动新的[内核][SELinux]，修改的docker配置文件。将配置文件的“–selinux-enabled”改成“–selinux-enabled=false”，然后再重启docker。

[root@centos-minion ~]# cat /etc/sysconfig/docker
    # /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
