CentOS使用阿里源安装最新版Docker

安装步骤:

1、卸载已经安装的Docker

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

2、配置阿里云yum源仓库
 sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 

3、查看可以安装的docker版本

#yum list docker-ce --showduplicates | sort -r //查看可以安装的版本并倒序排序

 

4、安装最新版本Docker
   注意：安装Docker最新版本，无需加版本号：
 sudo yum install -y docker-ce 

5、设Docker阿里云加速器

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://lkq3q0he.mirror.aliyuncs.com"]
}
EOF

6、启动Docker

 sudo systemctl daemon-reload //重新加载服务配置文件

 sudo systemctl enable docker.service && systemctl restart docker.service   //设置开机启动与重启docker服务

7、查看Docker版本
