Installing Nginx

NGINX is a popular choice for a reverse proxy because it is lightweight and has a high performance. It can also handle a large number of concurrent connections efficiently. To install it, run the following command.

apt update && apt install -y nginxCode language: Bash (bash)

Let’s configure nginx reverse proxy now. To do this run:

nano /etc/nginx/nginx.confCode language: Bash (bash)

After you have made changes to the nginx.conf file, you need to apply those changes to the nginx service for them to take effect. Here’s how you can do it:

1. Check the syntax of the nginx.conf file by running the following command:

sudo nginx -tCode language: Bash (bash)

This command will check the syntax of the nginx.conf file and report any errors.

2. If there are no syntax errors, reload the nginx service to apply the changes by running the following command:

sudo systemctl reload nginxCode language: Bash (bash)

This will apply the changes you made to the nginx.conf file without interrupting the active connections to the server.

Alternatively, you can also restart the nginx service to apply the changes, by running the following command:

sudo systemctl restart nginxCode language: Bash (bash)

This will stop and then start the nginx service, which will apply the changes you made to the nginx.conf file. However, this will also interrupt any active connections to the server.
