我们在安装centos 服务器时，可能会有以下情况：
局域网内有若干台服务器，但是只有一台服务器可以连接外网，其余服务器都不可以连接外网，但通过局域网与外网机器联通。
那么我们再使用 yum 安装软件时，可以采用以下方式
- 搭建本地 yum 源
- 使用nginx 代理 yum 源
其中方法1比较复杂且一旦需要第三方数据源时，更麻烦，因此我们这里介绍使用方法2。
1. 在有外网的服务器上安装 nginx
安装 epel 源
yum -y install epel-release
安装 nginx
yum -y install nginx
2. 配置nginx 代理 yum 源
新增 nginx 配置文件
vim /etc/nginx/conf.d/centos-7-yum.conf
输入以下内容，这里添加了一些常用的yum源，如果需要其他yum源可以自行添加
# centos 7 yum local source
server {
listen 7000;
server_name 192.168.251.148;
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Headers X-Requested-With;
add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
location / {
root html;
index index.html index.htm;
}
location /centos/ {
proxy_pass http://mirrors.aliyun.com/centos/;
}
location /epel/ {
proxy_pass http://mirrors.aliyun.com/epel/;
}
location /mariadb/ {
proxy_pass http://mirrors.ustc.edu.cn/mariadb/;
}
}
检查nginx 配置，并重载nginx配置
nginx -t nginx -s reload
3. 在没有外网的服务器上面配置 yum 源
备份以前的yum 源配置文件
cd /etc/yum.repos.dmv CentOS-Base.repo CentOS-Base.repo.bak
根据上方代理的 yum 源，创建如下配置文件，注意将ip 192.168.1.100 换成对应的有外网服务器的局域网ip
CentOS-Base-nginx.repo

刷新 yum 源
yum clean all yum makecache
