How to determine if Nginx has been successfully install…

There are several ways to determine if Nginx has been successfully installed:

1. To check Nginx processes, use the command ps -ef | grep nginx to see if there are any Nginx processes running on the system. If you can see the Nginx process information, it means Nginx has been successfully installed and is running.
2. Check the status of the Nginx service: Use the command ‘systemctl status nginx’ to check the running status of the Nginx service. If the service status is displayed as active (running), it means Nginx has been successfully installed and is running.
3. Visit the default Nginx page by entering the server’s IP address or domain name in a browser. If you can see the Nginx welcome page, it means Nginx has been successfully installed and can be accessed correctly.
4. Check the Nginx configuration file: Use the command nginx -t to verify if the syntax of the Nginx configuration file is correct. If there are no error messages, then the Nginx configuration file is correct and the installation is successful.
5. Check the installation directory of Nginx: By default, Nginx’s installation directory is /etc/nginx. You can use the command ls /etc/nginx to check if the directory exists and what files it contains.

You can determine if Nginx has been successfully installed using any of the above methods.
