How to configure reverse proxy access ip?Nginx reverse proxy settings in detail

First, reverse proxy in the end what the hell?

To put it bluntly, a reverse proxy is like a middleman. When you want to access a website, you don't go directly to the web server, but you go through this middleman. This has two advantages:First, it can hide the real server IPThe second is that it can help the server to spread the pressure of access.

For example, if you use your own server to set up a website, directly exposing the public IP is vulnerable to attacks. At this time, the set of reverse proxy, just like the server to wear a cloak of invisibility, hackers can not even touch your real IP.

Second, hand to teach you Nginx reverse proxy configuration

First, you need to understand the structure of the nginx configuration file. The main changes are/etc/nginx/nginx.confThis document, focusing onserverThis configuration block.

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

    location / {
        proxy_pass http://代理IP:端口; Here, put the proxy address provided by ipipgo.
        proxy_set_header Host $host.
        proxy_set_header X-Real-IP $remote_addr; }
    }
}

Knockout!proxy_passThe latter should be replaced with a proxy IP provided by ipipgo. e.g. with their dynamic residential proxy, the format might behttp://gateway.ipipgo.net:23000, depending on the access address given by the package.

Proxy IP practical skills

Select an agent type based on business needs:

A chestnut: do e-commerce price monitoring, use ipipgo's dynamic residential proxy, add a random switch in the nginx configuration:

upstream proxy_pool {
    server proxy_ip1:port; server proxy_ip2:port; server proxy_pool {
    server proxy_pool { server proxy_ip1:port; server proxy_ip2:port; server proxy_ip3:port
    server proxy_pool { server proxy_ip1:port; server proxy_ip2:port; server proxy_ip3:port.
}

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

iv. guide to demining common problems

Q: I can't access the reverse proxy after configuring it?
A：先检查防火代理是否开放了nginx端口（默认80/443），再用curl -v proxy IP:portTesting agent connectivity

Q: What should I do if my proxy IP is always blocked?
A: Switch to ipipgo'sStatic Residential AgentsThis type of IP has a long survival time and is suitable for scenarios that require stable connectivity.

Q: How can I tell if a proxy is in effect?
A: Visitshttps://ip.ipipgo.netThe IP shown should be a proxy IP and not the real IP of the server.

V. Why ipipgo?

This dynamic residential agent has a masterpiece - theAbility to assign city-level IPs. For example, if you want to simulate Shanghai user access, add parameters directly in the configuration:

proxy_pass http://sh.city.ipipgo.net:23000.

Their static proxies are even better.99.91 TP3T availabilityIt's not just talk. We tested 7 days of continuous hanging, IP froze without dropping, suitable for automated programs that need to hang for a long time.

One last nag: remember to turn on log monitoring with reverse proxies! In the nginx configuration, addaccess_log /var/log/nginx/proxy.log, check regularly for unusual access. You can contact ipipgo's tech support if you encounter problems, they respond more than twice as fast as regular vendors.
