Linux安装Docker

一键脚本安装

官方安装命令

curl -fsSL https://get.docker.com | bash -s docker

* 需要注意的是，官方的脚本中不支持RockuLinux和almalinux系统，需要自行修改一下脚本中系统版本判断函数中的代码，或者可以参考下面我修改好的

支持Rocky和Almalinux

curl -fsSL  https://dl.xp.sb/get-docker.sh | bash -s docker

YUM安装

yum源设置

1. download docker-ce.repo file

   [root@localhost ~]# wget https://download.docker.com/linux/centos/docker-ce.repo -P 

2. change docker yum repo from tsinghua web

   [root@localhost ~]# sed -i 's#download.docker.com#mirrors.tuna.tsinghua.edu.cn/docker-ce#g' /etc/yum.repos.d/docker-ce.repo
