yum源配置

1. 网络源

centos7
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
epel
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

2.本地yum

找一台内网服务器，可通过http，ftp，等将光盘文件共享出来

3. 自定义yum

[root@docker1-60 ~]# yum provides createrepo
[root@docker1-60 test]# createrepo /tmp/test
[root@docker1-60 ~]# cat /etc/yum.repos.d/test.repo 
[ansible]
name=ansible
baseurl=file:///tmp/test
enable=1
gpgcheck=0

createrepo

4.从yum源里下载rpm包（不安装）

# yum install 包名 --downloadonly --downloaddir="/tmp"
[root@docker1-60 ~]# yum  install ansible --downloadonly --downloaddir="/tmp"
