How to set up Nginx reverse proxy

Hi! Guys, today I am going to share with you how to set up Nginx reverse proxy. As an author who specializes in IP proxy knowledge, I know the importance of Nginx reverse proxy, so I'm here to tell you more about this interesting and useful technique.

What is Nginx Reverse Proxy

Nginx reverse proxy is a commonly used proxy technology that forwards client requests to multiple servers on the backend to achieve load balancing and high availability. Unlike forward proxying, Nginx reverse proxying hides the real back-end servers, making it impossible for clients to directly access the IP addresses of the back-end servers.

Steps to build an Nginx reverse proxy

Below, let's see how to build an Nginx reverse proxy step by step:

1. 1. Step 1: Install Nginx

First, we need to install Nginx. open a terminal and enter the following command:

apt-get install nginx

After waiting for the installation to complete, we can start the next step.

1. 1. Step 2: Configure Nginx

Next, we need to configure Nginx. open the Nginx configuration file, typically located at /etc/nginx/nginx.conf. In this file, we can specify configuration information for the reverse proxy.

vi /etc/nginx/nginx.conf

In the configuration file, we can use the following code to set up the reverse proxy:

location / {
    proxy_pass http://backend_servers;
}

In the above code, thebackend_serversis the address of the back-end server, either an IP address or a domain name.

1. 1. Step 3: Restart Nginx

Once the configuration is complete, we need to restart Nginx for the configuration to take effect.

service nginx restart

At this point, the Nginx reverse proxy has been successfully built!

Advantages of using Nginx reverse proxy

Nginx reverse proxy not only enables load balancing and high usability, but also has several advantages:

• Improve website performance: By distributing requests to multiple back-end servers, the Nginx reverse proxy effectively reduces the load on a single server and improves website responsiveness.
• Protect the back-end server: Nginx reverse proxy hides the real IP address of the back-end server, increasing the security of the server and effectively preventing malicious attacks.
• Provide flexible configuration options: Nginx reverse proxy provides a wealth of configuration options , you can according to the actual needs of flexible adjustment and optimization .

summarize

Through the introduction of this article, I believe that you already have a certain understanding of Nginx reverse proxy. By building Nginx reverse proxy, we can realize the advantages of load balancing, improving website performance and protecting the back-end server.
