Full process record of Nginx reverse proxy configuration

1. Preparation

Install Tomcat on Linux system, use the default port 8080, and start the Tomcat server

Can be accessed normally

Next, we want to forward the request to the Tomcat server through the Nginx reverse proxy. The port number of the Nginx reverse proxy server is exposed to the outside, while Tomcat is not exposed to the outside. The browser cannot access Tomcat directly, but can only access Tomcat through the Nginx reverse proxy server

2. Reverse proxy configuration

Configure the mapping between domain name and IP address in the hosts file of Windows system

You can access the Tomcat server through the domain name port 8080

Then configure request forwarding in Nginx and configure reverse proxy

At this time, port 8080 is not accessed, but the Nginx proxy server is directly accessed. Nginx will reverse the proxy and forward the request to the Tomcat server on port 8080.

You can also configure Nginx's reverse proxy to jump to services on different ports based on different access paths.

First, start two Tomcat servers with different ports, one configured with port 8081 and the other with port 8082.

Start two Tomcat servers

At this point, ports 8081 and 8082 are both accessible

Configure Nginx reverse proxy server

After configuring the reverse proxy, access the file8081 page under the /test8081/ path. Nginx will use the reverse proxy to access the Tomcat server on port 8081.

Visit the file8082 page under the /test8082/ path, Nginx will reverse proxy to access the Tomcat server on port 8082

This allows requests to be forwarded to different servers through reverse proxies based on different access paths.
