CentOS使用阿里源安裝最新版Docker

安裝步驟:

1、卸載已經安裝的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、配置阿里雲yum源倉庫
 sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 

3、查看可以安裝的docker版本

#yum list docker-ce --showduplicates | sort -r //查看可以安裝的版本並倒序排序

 

4、安裝最新版本Docker
   注意：安裝Docker最新版本，無需加版本號：
 sudo yum install -y docker-ce 

5、設Docker阿里雲加速器

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

6、啟動Docker

 sudo systemctl daemon-reload //重新加載服務配置文件

 sudo systemctl enable docker.service && systemctl restart docker.service   //設置開機啟動與重啟docker服務

7、查看Docker版本
