Nginx reverse proxy configuration method in detail

Hello everyone, today we are going to talk about a very amazing thing - how to configure Nginx reverse proxy. When it comes to Nginx, I'm sure many of you are no stranger to it. It is a high-performance HTTP and reverse proxy server that is widely used in the deployment of websites and applications. So, how to properly configure Nginx reverse proxy? Next, let me unveil this mystery with you!

Section 1: Nginx Installation and Basic Configuration

The installation of Nginx can be a proper, noob-friendly operation. First of all, we need to install Nginx by executing the following command under Linux:

shell
sudo apt-get update
sudo apt-get install nginx

Once the installation is complete, we need to do some basic configuration of Nginx. Open the Nginx configuration file `/etc/nginx/nginx.conf` and add the following:

user www-data; worker_processes auto; worker_processes auto; worker_processes auto
worker_processes auto;
pid /run/nginx.pid; events { events /run/nginx.pid; worker_processes auto; worker_processes
events {
worker_connections 1024; }
}
events { worker_connections 1024; } http {
sendfile on; } tcp_nopush on; }
tcp_nopush on;; tcp_nodelay on; tcp_nopush
tcp_nodelay on; keepalive_timeout 65; } http { sendfile on; tcp_nopush on
types_hash_max_size 2048; types_hash_max_size 2048
types_hash_max_size 2048;
include /etc/nginx/mime.types; default_type application/octet-stream; default_type application/octet-stream
default_type application/octet-stream; access_log /var/log/cp_nodelay on
access_log /var/log/nginx/access.log; error_log /var/log/nginx/access.log
error_log /var/log/nginx/error.log; error_log /var/log/nginx/error.log
gzip on;
include /etc/nginx/conf.d/*.conf; index index.html index.html index.html
index index.html index.htm index.nginx-debian.html;
server {
listen 80; server_name localhost; server_name; nginx-debian.html; server {
server_name localhost; server { listen 80; server_name localhost; server_name localhost; server_name localhost
server { listen 80; server_name localhost; location / {
server { listen 80; server_name localhost; location / { root /var/www/html; index index.html; server_name localhost
index index.html; }
}
}
}

This configuration code above ensures the basic functionality and security of Nginx while providing a simple virtual hosting configuration.

Section 2: Basic Concepts of Nginx Reverse Proxy

Before we get into reverse proxy configuration for Nginx, let's understand what a reverse proxy is. A reverse proxy is when a server accepts a request from a client and forwards the request to a real server on the internal network. In simple terms, it means that the client requests Server A, which actually forwards the request to Server B, which then returns the result to Server A and finally to the client. There are many benefits to this configuration, such as increasing the speed of access to the site, shunting the load, and so on.

Section 3: Configuring Nginx Reverse Proxy

Now, we've finally come to the main event - configuring the Nginx reverse proxy! First, we need to edit Nginx's virtual host configuration file `/etc/nginx/sites-available/default` by adding the following:

server {
listen 80; server_name your_domain.com; server_name your_domain.com
server_name your_domain.com; server_name your_domain.com; server_name your_domain.com
server { listen 80; server_name your_domain.com; location / {
proxy_pass http://your_backend_server; proxy_set_header
proxy_set_header X-Real-IP $remote_addr; }
}
}

In this example, we configured a simple reverse proxy. Forwards client requests to the backend server specified by `your_backend_server` via the `proxy_pass` directive, and adds an `X-Real-IP` HTTP header for the real client IP address.

Section 4: Advanced Configuration of Nginx Reverse Proxy

In addition to the basic reverse proxy configuration, Nginx provides many advanced configuration options that can further optimize the performance and security of the reverse proxy. Here, we list some common advanced configuration options for your reference:
Load balancing: Configure the load balancing method of the backend server via `upstream` directive, such as polling, IP hashing, etc.
Cache control: Setting up reverse proxy caching rules via the `proxy_cache` directive improves access speed and reduces server load.
Security Filtering: Filtering illegal requests through the `proxy_set_header` directive to protect the server and website.
HTTPS support: Configure HTTPS support for the Nginx reverse proxy with the `proxy_ssl_certificate` and `proxy_ssl_certificate_key` directives.

Through the above introduction, I believe you have a clearer understanding of how to configure the Nginx reverse proxy. Of course, the Nginx reverse proxy has many advanced and complex features that need to be configured according to specific needs and scenarios. I hope this article can provide you with some help, so that you can be more comfortable when using the Nginx reverse proxy. Remember, with the right configuration, the Nginx reverse proxy will bring you better performance and stability for your websites and applications.
