利用nginx 来实现内网yum源(反向代理)

简介

在项目部署时，尤其是在政府企业，对于外网简直是奢望，但是对于运维来说，没有外网的话只能自建yum源。我今天来说的是一种简单的自建yum源方法，前提是必须有一台内外网都有的机器，我们一般称为前置机。

操作思路

1、使用nginx 反向代理 阿里云源

2、在内网机器自建repo指向nginxip

nginx配置

1 2 3 4 5 6 7 8

server { listen 80; location /centos/ { proxy_pass http://mirrors.aliyun.com/centos/ ; } }

比较简单，不过我们要求不高能用即可。

另外我们常用的linux系统是Centos，所以我这边只写了Centos的。其它的你也可以参考上面配置配置。

内网机器配置

1、备份CentOS-Base.repo

1	# mv CentOS-Base.repo CentOS-Base.repo.bak

2、增加反向代理的repo

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

vim /etc/yum.repos.d/Centos-7.repo [base] name=CentOS-$releasever - Base - 10.12.64.130 failovermethod=priority baseurl=http://10.12.64.130/centos/$releasever/os/$basearch/ http://10.12.64.130/centos/$releasever/os/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os gpgcheck=1 gpgkey=http://10.12.64.130/centos/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates - 10.12.64.130 failovermethod=priority baseurl=http://10.12.64.130/centos/$releasever/updates/$basearch/ http://10.12.64.130/centos/$releasever/updates/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates gpgcheck=1 gpgkey=http://10.12.64.130/centos/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras - 10.12.64.130 failovermethod=priority baseurl=http://10.12.64.130/centos/$releasever/extras/$basearch/ http://10.12.64.130/centos/$releasever/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras gpgcheck=1 gpgkey=http://10.12.64.130/centos/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus - 10.12.64.130 failovermethod=priority baseurl=http://10.12.64.130/centos/$releasever/centosplus/$basearch/ http://10.12.64.130/centos/$releasever/centosplus/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus gpgcheck=1 enabled=0 gpgkey=http://10.12.64.130/centos/RPM-GPG-KEY-CentOS-7 #contrib - packages by Centos Users [contrib] name=CentOS-$releasever - Contrib - 10.12.64.130 failovermethod=priority baseurl=http://10.12.64.130/centos/$releasever/contrib/$basearch/ http://10.12.64.130/centos/$releasever/contrib/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib gpgcheck=1 enabled=0 gpgkey=http://10.12.64.130/centos/RPM-GPG-KEY-CentOS-7

注：其中的10.12.64.130为我的前置机ip地址，大家可以更具情况自行修改。

测试

1 2	# yum makecache

在随机安装一个net-tools 测试即可

以上
