“vi /etc/sysconfig/selinux    把selinux后面的改为disabled,重启一波机器,再重启docker就可以了”

确实这个问题,我修改了, reboot后就OK了

谢谢分享!

现象:Centos7.3通过yum安装完docker后,启动docker失败

机器的系统版本:CentOS Linux release 7.3.1611 (Core)

centos7,执行完安装命令: yum -y install docker

执行启动命令: systemctl   start docker  ,报如下错误:

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 disable selinux in docker (--selinux-enabled=false)

原因分析:  此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



重新编辑docker配置文件:

复制代码

[root@localhost lib]# vi /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
"/etc/sysconfig/docker" 26L, 1100C written
[root@localhost lib]# systemctl start docker[root@localhost lib]#

复制代码

重新启动docker服务:systemctl  start  docker
