默认情况下，CentOS7.9下有两种方法可以安装docker，分别是在线安装docker和离线安装docker(伪离线，最后还是需要网络支持)
1.环境信息
HostName |
IPAddress |
OS Version |
Docker Version |
Note |
centos79 |
172.20.10.12 |
CentOS Linux release 7.9.2009 (Core) |
Docker version 23.0.6, build ef23cbc |
网络需要能连接外网等 |
2.docker安装
2.1.在线docker安装
-->下载docker-ce.repo文件
命令：
cd /etc/yum.repos.d
wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
OR
wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
-->安装docker
命令：
yum install docker-ce -y
systemctl restart docker
systemctl status docker
[root@centos79 ~]# systemctl restart docker
[root@centos79 ~]# systemctl status docker
