Configuring and Using Nginx Reverse Proxy on CentOS Systems

environmental preparation

To configure and use the Nginx reverse proxy on a CentOS system, you first need to make sure that Nginx is already installed on your system. if it is not already installed, you can install it with the following command:

“`
sudo yum install nginx
“`

Once the installation is complete, you can start the Nginx service with the following command:

“`
sudo systemctl start nginx
“`

Configuring Nginx Reverse Proxy

Configuring the Nginx reverse proxy requires modifying the Nginx configuration file. First locate the Nginx configuration file, usually located at `/etc/nginx/nginx.conf` or `/etc/nginx/conf.d/default.conf`. Open the configuration file, find the `server` block and add the following configuration to it:

“`
location / {
proxy_pass http://your_backend_server.
proxy_set_header Host $host.
proxy_set_header X-Real-IP $remote_addr.
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
“`

Where `http://your_backend_server` is the address of the backend server you want to proxy. Once the configuration is complete, reload the Nginx configuration file:

“`
sudo nginx -s reload
“`

Using Nginx Reverse Proxy

Once the configuration is complete, Nginx forwards all requests to the specified back-end server. You can access the services of the back-end server by accessing the IP address or domain name of the Nginx server. For example, if you configure a reverse proxy to proxy the back-end web application, you can access the back-end web application by accessing the IP address or domain name of the Nginx server.

Above is the whole process of configuring and using Nginx reverse proxy on CentOS system, through a simple configuration, you can realize the request forwarding to the specified back-end server. I hope this article will be helpful to you!

Through the above steps, we can easily configure and use Nginx reverse proxy on CentOS system to realize request forwarding and load balancing. At the same time, the high performance and stability of Nginx can also ensure the stable operation of the proxy service. I hope the above content can help you better understand and apply Nginx reverse proxy technology.
