Apache or Nginx can be used on VPS and Dedicated Servers. To see if Apache is running, type the following command.

If Apache is up and running, you’ll see something like this.
Apache is not running if there is no output. Instead, use the Nginx command below to make sure it’s up and running.

Version and status of Nginx
Only VPS and Dedicated Servers come with Nginx.

This command only displays the Nginx version on a VPS or Dedicated Server. It doesn’t say whether Nginx is up and running. Instructions for using Nginx instead of Apache on your private server can be found in the following article.

How to Switch to Nginx as Your Web Server
To see what version of Nginx you have installed, do the following command.

nginx version: nginx/1.14.1 $ /usr/sbin/nginx -v
Determine whether Nginx is installed on a VPS or Dedicated Server.
To see if Nginx is running, type the following command.

If Nginx is up and running, you’ll see something like this.
Nginx is not operating if there is no output. Instead, use the Apache command to verify that it is up and functioning.
[server]
grep nginx 12708 | ps -acx nginx 26797? Ss 0:02 nginx 26797? nginx 26798? S 0:00 nginx 26798? nginx nginx nginx nginx nginx
