Server Proxy Forwarding in Action: 10 Minute Tutorial on Nginx Reverse Proxy Configuration

Ten minutes to get started with Nginx reverse proxy

Many developers need to quickly build a proxy service but are stuck in the configuration link, here to teach you not to write complex code, use theNginx reverse proxy + proxy IPCombined to realize the business needs. This tutorial has been tested with CentOS 7, other Linux distributions operate with the same logic.

Don't be sloppy with your preparations.

Make sure the three pieces are in place first:

1. Nginx installed(run nginx -v to verify)
2. Get ipipgo proxy IP(HTTP/Socks5 protocol support)
3. Clarify the target website domain name

Special reminder when choosing a proxy IP, it is recommended to use ipipgo'sResidential IP Resource PoolThe characteristics of its simulation of the real user network environment can effectively reduce the probability of being recognized by the target server.

Three Steps to Core Configuration

Open the nginx.conf configuration file (path: /etc/nginx/nginx.conf) and add it inside the http module:

server {
    listen 80; server_name your domain name; server_name
    server_name your domain name.

    location / {
        proxy_pass http://目标网站域名; proxy_set_header
        proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header
        proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_addr
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

         Access ipipgo proxy IP
        resolver 8.8.8.8 valid=300s;
        proxy_http_version 1.1;
        proxy_pass_request_headers on; proxy_pass_header Server; proxy_pass_headers
        proxy_pass_header Server;
    }
}

Essential Tips for Advanced Players

When the need arisesMultiple IP RotationWhen you do, add the load balancing module to the configuration file:

upstream proxy_pool {
    server proxy_pool { server proxy_ip1:port weight=5; server proxy_ip2:port weight=3; server proxy_pool { upstream proxy_pool {
    server proxy_pool { server proxy_ip2:port weight=3; server proxy_ip3:port weight=2; server proxy_pool
    server proxy_pool { server proxy_ip1:port weight=5; server proxy_ip2:port weight=3; server proxy_ip3:port weight=2; }
}

server {
    ...
    proxy_pass http://proxy_pool; }
}

Here we recommend using ipipgo'sDynamic Residential IP ServiceThe automatic IP switching feature avoids frequent manual maintenance of the proxy pool, especially in scenarios that require long-term stable operation.

QA First Aid Kit

Q：After the configuration is saved, the access reports 502 error?
A: First check the proxy IP connectivity, it is recommended to use curl -x "proxy IP:port" target URL to do the test. ipipgo IP provided by the strict quality testing, can reduce the probability of such problems!

Q: How can I verify if the agent is in effect?
A: Visit the website of whatismyipaddress.com, if the IP shown is the proxy IP instead of the real IP of the server, then the configuration is successful!

Q: What should I do if I encounter frequent IP blocking?
A: Switching the use of ipipgoHigh Stash Residential IPThe technology of hiding proxy features can effectively reduce the probability of banning, and it is also recommended to set a reasonable access frequency.

After completing the above steps performnginx -s reloadMake the configuration effective. The actual business can be adjusted according to the need to cache policy, timeout time and other parameters, but the core proxy logic according to this tutorial can quickly run through.
