Practical case of Nginx reverse proxy configuration

1. Achieve goals

Reverse proxy, for example, is that multiple domain name A records are the same server and access port 80 at the same time, but the server can automatically assign it to local ports such as 8000, 8080, etc.

Example: Access imustctf.topwill point to 127.0.0.1:8000the port of the domain name A record IP

2. Practical operation begins

Currently there are two static front-end sites under the WWW directory

First configure the seelgo project, which is just a front-end page managed by php, without an additional back-end server, so the configuration is very simple:

server {
    
    
    listen       88;
    server_name  seelgo;
    # 指定前端项目所在的位置
    location / {
    
    
        root   D:/CStools/phpstudy_pro/WWW/seelgo;
        index  index.html index.htm;
    }
}

Try accessing port 88:

Then configure the secureqr project, which is a project with a front-end and back-end separation architecture. There is an additional back-end server, so it needs to be configured locationfor forwarding:

server {
    
    
    listen       8689;
    server_name  secureqr;
    # 指定前端项目所在的位置
    location / {
    
    
        root   D:/CStools/phpstudy_pro/WWW/secureqr;
        index  index.html index.htm;
    }

    
    location /api/ {
    
    
        # 开启重写日志记录，这个会记录在error.log里面，级别为notice
        rewrite_log on;
        # 重写规则，可根据实际情况调整。
        rewrite ^/api/(.*)$ /$1 break;
        proxy_pass http://127.0.0.1:8589;
        proxy_redirect    off;
        proxy_set_header  Host $host;
        proxy_set_header  X-real-ip $remote_addr;
        proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

Try accessing port 8689:
