Centos7的yum安装可参考：Centos7配置 yum源
1、安装docker
1）卸载docker旧版本
sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine
2）安装相关依赖
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
3）设置docker稳定版存储库
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
4）安装docker引擎
sudo yum install docker-ce docker-ce-cli containerd.io
5）启动docker
sudo systemctl start docker
6）验证docker是否安装成功
sudo docker run hello-world
7）设置docker开机自启
sudo systemctl enable docker
2、镜像源配置
1）创建镜像源目录
sudo mkdir -p /etc/docker
2）写入daemon.json
sudo vi /etc/docker/daemon.json
{
"registry-mirrors": [
"https://docker.m.daocloud.io",
"https://docker.imgdb.de",
"https://docker-0.unsee.tech",
"https://docker.hlmirror.com",
"https://docker.1ms.run",
"https://func.ink",
"https://lispy.org",
"https://docker.xiaogenban1993.com"
]
}
3）重启docker
sudo systemctl daemon-reload
sudo systemctl restart docker
