Code:
# cd /etc/httpd/conf.d
# sed -i “s/8080/80/” *.conf
# sed -i “s/8443/443/” *.conf
As the final step, rebuild the vhost configs using this command - # for user in $(v-list-sys-users plain); do v-rebuild-web-domains $user; done

For Debian/Ubuntu

If you’re using a Debian or Ubuntu OS for running your systems, follow these steps:

Stop Nginx service using this command -
Code:
# service nginx stop
Remove the installed Nginx package using this command -
Code:
# apt-get remove nginx
Run the below commands to change Vesta configuration:

Code:
# cd /usr/local/vesta/conf
# sed -i “/PROXY_*/d” vesta.conf
# sed -i “s/8080/80/” vesta.conf
# sed -i “s/8443/443/” vesta.conf
Change httpd config using the below commands:

Code:
# cd /etc/apache2/conf.d
# sed -i “s/8080/80/” *.conf
# sed -i “s/8443/443/” *.conf
Lastly, rebuild vhost configuration using this command - # for user in $(v-list-sys-users plain); do v-rebuild-web-domains $user; done

These steps will remove teh Nginx web server from your Linux server.

Nginx Errors While Removing

When running the removal process, you might come across some errors. Especially when you execute this command, you’ll notice an error - bash vst-install.sh

The error message will be -

Code:
“Following packages are already installed:
nginx
It is highly recommended to remove them before proceeding.
If you want to force installation run this script with -f option:
Example: bash vst-install-ubuntu.sh –force”
As and when you get this error, you can remove Nginx using the commands mentioned below:

Code:
sudo apt-get remove nginx
sudo apt-get purge nginx
sudo apt-get autoremove
Once Nginx along with its config files are removed, use either of the following:

Use -f flag mentioned as directed by the installer

Using a stock OS image, rebuild the droplet from the Vesta Control Panel.

But it’s highly recommended that you start from a clean server rather than cleaning it or removing packages. If you face further difficulty while removing Nginx, contact your hosting provider.
