webserver set proxy ip: Nginx/Apache server proxy configuration program

Teach you how to use Nginx/Apache to build proxy servers

The old iron engaged in web development should have encountered this situation: their servers to docking third-party interfaces, the results of other people's interfaces to limit the frequency of access. This time on the server to hang a proxy IP can be a perfect solution, today we will nag how to use the most common Nginx and Apache the whole job.

Why do I need to hang a proxy on my server?

To give a real scenario: you have a crawler program running on AliCloud, the target site to AliCloud's IP segment all blacked out. At this time through the server forwarding request, with a proxy IP access to the target site, just like the Monkey King seventy-two changes, easy to bypass the restrictions.

I'd like to introduce you to our family.ipipgo proxy serviceThe IP resources of more than 200 countries in the world support HTTP/HTTPS/Socks5 protocols, and it is easy for thieves to dock.

Nginx proxy configuration in practice

Open the nginx.conf configuration file and add these lines to the server block:

location /api {
    proxy_pass http://目标网站域名; proxy_set_header Host $host; 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_add_x_forwarded
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

     Here comes the kicker! Set the proxy IP here
    resolver 8.8.8.8 valid=30s;
    set $proxy_server "http://用户名:密码@gateway.ipipgo.com:端口";
    proxy_pass $proxy_server;
}

Tips for setting up an Apache proxy

Find the httpd.conf file and enable both modules:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

Then add it in the VirtualHost configuration segment:

ProxyRequests Off
ProxyPass "/api" "http://目标网站域名"
ProxyPassReverse "/api" "http://目标网站域名"

 Proxy IP Configuration Key Steps
ProxyRemote "http://目标网站域名" "http://用户名:密码@gateway.ipipgo.com:端口"

Here's a pitfall to be aware of: Apache'sProxyRemoteThe command is not very friendly to HTTPS support, it is recommended to directly use the Socks5 protocol provided by ipipgo is more secure.
