Centos7安装Docker及卸载

环境：Centos7.9版本

[root@docker01 ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

1、删除本地docker相关包

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

2、安装相关环境工具

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

3、配置yum镜像仓库

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

4、安装Docker、启动、停止

安装
yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin
启动
systemctl start docker
停止
systemctl stop docker
检测
docker version

5、配置docker镜像加速器

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://dfrs0u9f.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

6、卸载

yum remove docker-ce docker-ce-cli containerd.io docker-compose-plugin
rm -rf /var/lib/docker
rm -rf /var/lib/containerd
