yum方式安装Docker

1.查看Centos版本命令

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

这里CentOS Linux release

7.9

.2009 (Core)的版本必须大于3.0

2.需要确保当前安装的CentOS系统可以上网

[root@suzhongde suzhongde]# ping www.baidu.com
PING www.a.shifen.com (163.177.151.109) 56(84) bytes of data.
64 bytes from 163.177.151.109 (163.177.151.109): icmp_seq=1 ttl=54 time=9.02 ms
64 bytes from 163.177.151.109 (163.177.151.109): icmp_seq=2 ttl=54 time=9.83 ms
64 bytes from 163.177.151.109 (163.177.151.109): icmp_seq=3 ttl=54 time=9.60 ms
64 bytes from 163.177.151.109 (163.177.151.109): icmp_seq=4 ttl=54 time=9.77 ms

3.使用yum安装gcc相关依赖

# 在终端依次输入以下命令
yum -y install gcc
yum -y install gcc-c++

4.如果以前安装过docker 请卸载它们以及相关的依赖项

# 在终端输入以下命令
yum remove docker \
            docker-client \
            docker-client-latest \
            docker-common \
            docker-latest \
            docker-latest-logrotate \
            docker-logrotate \
            docker-engine

5.安装

yum-utils

包

[root@suzhongde suzhongde]# yum install -y yum-utils
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: ftp.sjtu.edu.cn
 * extras: mirrors.163.com
 * updates: mirrors.cn99.com
Package yum-utils-1.1.31-54.el7_8.noarch already installed and latest version
Nothing to do

6.设置

稳定

的存储库

[root@suzhongde suzhongde]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
Loaded plugins: fastestmirror, langpacks
adding repo from: http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
grabbing file http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo

7.配置yum源之后更新软件包的索引

[root@suzhongde suzhongde]# yum makecache fast
