1.1，先卸载老的
yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine
1.2 ,安装准备
安装所需的软件包。yum-utils 提供了 yum-config-manager ，并且 device mapper 存储驱动程序需要 device-mapper-persistent-data 和 lvm2。
yum -y install gcc gcc-c++
yum install -y yum-utils device-mapper-persistent-data lvm2
1.3,换源
# 官方的源
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
1.4 安装
yum -y install docker-ce docker-ce-cli containerd.io docker-compose-plugin
1.5,启动
systemctl start docker
systemctl stop docker
# 查看版本
docker version
1.6,hello word
docker run hello-world
1.7 删除
yum remove docker-ce docker-ce-clie containerd.io
# 删除文件
rm -rf /var/lib/docker
rm -rf /var/lib/containerd
2.12、安装docker-compose
curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
很慢
看一下最新版本
https://github.com/docker/compose/releases/
是2.23.3
下不下来
https://github.com/docker/compose/releases/download/v2.23.3/docker-compose-linux-x86_64
手动下载docker-compose-linux-x86_64吧，浏览器也下载到9M就歇逼，还是迅雷吧
mv docker-compose-linux-x86_64 docker-compose 换个名字 ，麻蛋的
chmod +x /usr/local/bin/docker-compose
创建软连
ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
docker-compose --version
