移除掉旧的版本

yum remove docker 
          docker-client 
          docker-client-latest 
          docker-common 
          docker-latest 
          docker-latest-logrotate 
          docker-logrotate 
          docker-selinux 
          docker-engine-selinux 
          docker-engine

删除所有旧的数据

rm -rf /var/lib/docker

安装依赖包

yum install -y yum-utils
device-mapper-persistent-data
lvm2

使用下面的命令安装稳定版仓库，即使安装最新体验版或者是测试版也需要稳定版仓库

yum-config-manager
--add-repo
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

可选：体验版和测试版默认是关闭的，你可以通过下面的命令打开，不打开也不影响稳定版的使用

打开体验版与测试版

yum-config-manager --enable docker-ce-edge
yum-config-manager --enable docker-ce-test

关闭体验版与测试版

yum-config-manager --disable docker-ce-edge
yum-config-manager --disable docker-ce-tes

配置缓存

yum makecache fast

安装指定版本的docker CE

yum list docker-ce --showduplicates | sort -r
yum install -y docker-ce-18.03.0.ce

安装最新稳定版本的docker

sudo yum install -y docker-ce

容器引擎配置镜像加速器

mkdir -p /etc/docker
tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["http://hub-mirror.c.163.com"]
  "live-restore": true  #daemon服务不可用的时候，容器依旧保持运行状态
  #"graph": "/data/docker"
  #"insecure-registries": [],    # 设置docker的私有仓库地址
  #"bip": "",  #网络
  #"exec-opts": [],
}
EOF

启动docker引擎并设置开机启动

systemctl start docker
systemctl enable docker

配置当前用户对docker的执行权限

groupadd docker
gpasswd -a ${USER} docker
systemctl restart docker
