Centos离线安装Docker
下载离线安装包
下载地址： https://download.docker.com/linux/static/stable/x86_64/
这里选择了 docker-19.03.12.tgz
禁用SELinux
如果不禁用的话，本人遇到过如下问题：在开启防火墙的情况下，执行systemctl start docker 卡死。 关闭防火墙后，上面的命令就能正常启动
vi /etc/selinux/config
编辑上面的文件把SELINUX设置为disabled，重启后生效，如果不重启可以通过命令临时生效: setenforce 0
解压
tar -zxvf 离线安装包
mv docker/* /usr/bin
编辑开机启动脚本
vi /etc/systemd/system/docker.service
粘贴下面的内容：
