nginx reverse proxy set proxy ip: Nginx reverse proxy configuration proxy IP address

Teach you to use Nginx anti-proxy proxy IP handily

Folks who have worked in web development know thatReverse proxies are a universal staging area.The first thing you need to do is to get the Nginx backend to work with proxy IPs. Today we focus on how to make Nginx anti-generation with proxy IP work, especially with ipipgo proxy resources to the whole job. This trick is especially suitable for the need to batch processing requests without exposing the local IP scenarios, such as data collection, interface debugging these serious business.

Configuration Principle Revealed

The Nginx reverse proxy is, quite frankly, a middleman:
1. User requests go to the Nginx server first
2. Nginx takes the proxy IP to fetch data from the target website.
3. Returning the retrieved data to the user in the same way as it was retrieved
The whole process is like getting an errand boy, the key is to match the boy with transportation (proxy IP).

http {
    server {
        server { listen 80;
        location / {
            proxy_pass http://目标网站地址; 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-Real-IP $remote_addr; proxy_set_header
             This should be replaced with the proxy IP provided by ipipgo.
            resolver 8.8.8.8; set $proxy_header
            set $proxy_server "ipipgo proxy IP:port";
            proxy_pass http://$proxy_server;
        }
    }
}

Four Steps to Real-World Configuration

Step 1: Install Nginx
Execute thesudo apt install nginx(Ubuntu system), other systems change the install command themselves.

Step 2: Profile Surgery
locate/etc/nginx/nginx.conffile, add this configuration to the http module:

proxy_connect_timeout 60s; proxy_read_timeout 600s; proxy_read_timeout 600s; proxy_read_timeout 600s
proxy_read_timeout 600s; proxy_send_timeout 600s; proxy_send_timeout 600s
proxy_send_timeout 600s.
proxy_buffering off.

Step 3: Proxy IP Access
Putting the code example in theipipgo Proxy IP:PortReplace it with real information. This is the recommended match if using dynamic residential agents:

set $proxy_server "dynamic.ipipgo.com:32000";

Step 4: Restart the service to see the effect
fulfillmentsudo nginx -s reloadTo make the configuration take effect, use thecurl -x your server IP Destination URLTest whether to go proxy.

Guide to avoiding the pit (QA session)

Q: What should I do if I realize I didn't go proxies after matching?
A: Look at the Nginx logs firsttail -f /var/log/nginx/error.log, focus on checking that the proxy IP format is correct. ipipgo's proxy address should come with a port number, don't miss it.

Q: What about the snail-like agent speed?
A: Try to switch the type of agent. Use dynamic residence for data collection, choose static residence for stable connection, and go directly to their international private line for cross-border business.

Q: How to change IP automatically?
A: ipipgo's API can directly get the latest IP, with a timed task to update the Nginx configuration on the line. They also have a client with automatic switching function, than write their own scripts to save time.

How to choose a ipipgo package

Right-sized according to business needs:

Here's the kicker.Static Home Package: 35 bucks a month to buy a fixed IP, much cheaper than buying a cloud server. Suitable for scenarios that require whitelist verification, API calls, remember to set access frequency limits in Nginx, don't get the IP blocked.

Advanced Play Expansion

For a fun twist try these:
1. Multiple proxy IP polling configuration (need to buy the enterprise version of the package)
2. Automatic switching of country nodes according to the target site
3. Automatic IP switching for abnormal traffic
All of these features are supported by ipipgo's API, and specific code examples are readily available in their home documentation.

One final rant:Proxy IPs are not a silver bulletIf you want to use a customized solution, you have to use reasonable timeout settings and request frequency control to make it work stably. If you have any problems, you can go directly to ipipgo's technical support, and their 1v1 customized solutions can really solve some strange needs.
