Proxy configuration of Nginx reverse proxy web container

Nginx is a high-performance reverse proxy server that can provide static content, load balancing, caching and other services. In web applications, Nginx can be used as a reverse proxy server while handling HTTP requests and responses through proxy configuration. This article will introduce how to configure the proxy settings of the web container of Nginx reverse proxy.

1. Install Nginx

First you need to install Nginx. For specific methods, please refer to Nginx official documentation. After the installation is complete, start the Nginx server.

2. Configuring the proxy server

Configuring the proxy server requires editing the Nginx configuration file. Under Ubuntu systems, this file is located at /etc/nginx/nginx.conf. In this file, you can add the following content:

upstream backend {
    server 192.168.1.10:8080;
}
server {
    listen 80;
    server_name example.com;
    location / {
        proxy_pass http://backend;
    }
}

In the above configuration, an upstream server named "backend" is defined, its IP address is 192.168.1.10, and the port number is 8080. At the same time, a server block named example.com is defined with proxy settings configured to forward all requests to an upstream server named "backend".

The "location /" statement in the above configuration file can also be replaced by one of the following two modes:

• location /foo/: means only Only requests whose request address starts with "/foo/" will be forwarded to the upstream server by the proxy;
• location ~ .(jpg|jpeg|png|gif|ico)$: means only Only requests whose file names end with "jpg", "jpeg", "png", "gif" or "ico" will be forwarded to the upstream server by the proxy.

3. Reload the Nginx server

After modifying the configuration file, you need to reload the Nginx server to make it take effect. You can use the following command to achieve this:

sudo service nginx reload

4. Verify proxy

After completing the above steps, you can verify whether the proxy is working properly through a web browser. Enter the server domain name (such as example.com) into your browser to access it.

Summary

Through the above steps, you can use Nginx as a reverse proxy server and forward HTTP requests to the application on the web container through proxy settings. Through Nginx's reverse proxy, more efficient load balancing and caching functions can be achieved in web applications.
