How to set up nginx reverse proxy on Ubuntu?

To set up an nginx reverse proxy, you need to follow these steps:

1. Install nginx: Run the following command in the terminal to install nginx:
2. Please update using sudo apt and then install nginx.
3. Configure the proxy server: Edit the nginx configuration file /etc/nginx/nginx.conf:
4. Open the nginx.conf file using the text editor nano with root privileges.
5. Add a server block to the configuration file, specifying the IP address and port of the target server for reverse proxy.
6. Server {
   Listen on port 80;
   Server name your_domain.com;

   For any requests, redirect to target server IP and port;
   Set Host header to $host;
   Set X-Real-IP header to $remote_addr;
   }

7. Replace your_domain.com with the domain name you want to proxy, and target_server_ip and target_server_port with the IP address and port of the target server.
8. Save and close the file.
9. Verify if the syntax of the nginx configuration file is correct.
10. Check the configuration of nginx.
11. Reload the nginx configuration if there are no errors.
12. Restart nginx using systemctl.

Now, your nginx server will reverse proxy the target server based on the settings in the configuration file. You can access the nginx server using the domain name you specified, and nginx will route the requests to the target server.
