nginx代理 yum 源

发布时间 2023-12-28 11:12:04作者: Macoffee
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
介绍使用方法2。方法1略。。后续再说
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
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

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
