- Backup Configuration: Make sure to backup the configuration files and any custom modifications you have made. These files are typically located in the /etc/nginx directory. This will ensure that you can easily restore the configuration if needed.
- Check Dependencies: Nginx may have dependencies on other software packages or libraries. Check if any other applications rely on Nginx and determine if you still need those applications. Uninstalling Nginx may cause issues for other software that depends on it.
- Stop Nginx: Ensure that Nginx is stopped before uninstalling it. You can do this by running the following command: sudo systemctl stop nginx
- Remove Nginx Packages: To uninstall Nginx, you need to remove the Nginx packages from your system. The exact package name may vary depending on your Linux distribution. For example, on Ubuntu, you can use the following command: sudo apt-get remove nginx
- Remove Nginx Files: After uninstalling Nginx, some configuration files or log files may still exist. You can manually remove these files using the following command: sudo rm -rf /etc/nginx /var/log/nginx
- Verify Uninstallation: Double-check that Nginx is successfully uninstalled by attempting to start it again and check for any remnants. Alternatively, you can check if the Nginx process is running using the following command: ps aux | grep nginx
Always exercise caution when uninstalling software and ensure that you have a backup and understanding of the potential impacts on your system before proceeding.

Does uninstalling Nginx affect SSL certificates and HTTPS configurations?
Uninstalling Nginx does not directly affect SSL certificates and HTTPS configurations. However, it will stop Nginx from serving the HTTPS requests, thus rendering the SSL certificates and HTTPS configurations useless until another web server is set up or Nginx is reinstalled. It is important to note that if the SSL certificates were installed and managed by Nginx itself, removing Nginx may make it more difficult to manage or renew the certificates in the future.
