CentOS7 安装Docker

参考地址：https://docs.docker.com/engine/install/centos/

1.yum安装gcc相关

yum -y install gcc
yum -y install gcc-c++

2.卸载旧版本

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

3.安装软件包

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

4.设置stable镜像仓库

这里不使用官方的镜像，太慢了！改用阿里云的镜像

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

5.更新yum软件包索引

yum makecache fast

6.安装Docker-ce

yum install -y docker-ce docker-ce-cli containerd.io

7.启动Docker

systemctl start docker
docker version
docker run hello-world

8.设置阿里云镜像加速

mkdir -p /etc/docker
vim  /etc/docker/daemon.json

{
  "registry-mirrors": ["https://6s5e9vi3.mirror.aliyuncs.com"]
}

systemctl daemon-reload
systemctl restart docker

9.卸载

systemctl stop docker 
yum -y remove docker-ce
rm -rf /var/lib/docker
