reverse proxy server how to set ip, reverse proxy real server ip

Hi everyone, today I would like to talk to you about how to set up a reverse proxy server. Maybe many of you don't know much about reverse proxy server, but it is very important in practical application. So, next I will introduce the setting method of reverse proxy server in detail, hope it can help you.

What is a reverse proxy server?

First, let's understand what a reverse proxy server is. Simply put, a reverse proxy server is a proxy server located on the server side. When a client initiates a request, the request is first sent to the reverse proxy server, which then forwards the request to the target server and finally sends the response from the target server to the client. Such a setup can hide the information of the real server, improve security, and also realize functions such as load balancing, which is very practical.

How to set up a reverse proxy server?

Next, I will describe how to set up a reverse proxy server in Nginx and Apache. Both are common and widely used in practice.

Nginx Setting Up a Reverse Proxy Server

First, we need to add a reverse proxy configuration to the Nginx configuration file. For example, we can configure a reverse proxy like this:

server {
listen 80; server_name example.com; server_name
server_name example.com;

location / {
proxy_pass http://backend; 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;
}

}

In the above configuration, we listen on port 80 and specify the domain name as example.com. Then in the location, we set the proxy forwarding rules. proxy_pass specifies the forwarding destination server address, and proxy_set_header sets some header information to pass the client's real IP and other information.

Apache Setting Up a Reverse Proxy Server

For Apache, we can also add reverse proxy configuration in the configuration file. Add a configuration similar to the following to httpd.conf:

ServerName example.com

ProxyPass / http://backend/
ProxyPassReverse / http://backend/

Here, we have set up the reverse proxy rules through ProxyPass and ProxyPassReverse to forward the request to the target server backend.

Other settings

In addition to the basic configuration mentioned above, we can also make more customized settings for the reverse proxy server. For example, you can set up caching, load balancing, SSL and other features to improve performance and security.

summarize

Through the above introduction, I believe you have a clearer understanding of how to set up a reverse proxy server. Whether in Nginx or Apache, you can use a simple configuration to realize the reverse proxy. Of course, for different scenarios and needs, we can also do more customized configuration to meet the actual application requirements.
