Uninstalling Nginx completely from the system

To stop the Nginx service and remove it from the autoloader, the following command is provided:

$ sudo systemctl stop nginx
$ sudo systemctl disable nginx

$ sudo apt purge nginx nginx-common

To remove packages that were installed during the Nginx installation but are no longer needed, execute:

Use:

$ sudo rm -Rf /etc/nginx/*
