Enable the service of nginx

[root@linuxhelp ~]# systemctl enable nginx
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.

Start the service of Nginx

[root@linuxhelp ~]# systemctl start nginx

Check the status of nginx as follows

[root@linuxhelp ~]# systemctl status nginx
● nginx.service - nginx - high performance web server
   Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)
Active: active (running) since Thu 2019-06-06 14:30:57 IST; 11s ago
     Docs: http://nginx.org/en/docs/

Check the port number that nginx is listening to.

[root@linuxhelp ~]# netstat -tulpn | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      32078/nginx: master 

Modify the port number in the configuration file of nginx inside the server block to 8989

[root@linuxhelp ~]# vim /etc/nginx/nginx.conf
server {
	listen       8989 default_server;
	listen       [::]:8989 default_server;
	server_name   _;
	root         /usr/share/nginx/html;
}

Modify the port number of Nginx in default.conf as 8989 as follows:

[root@linuxhelp ~]# vim /etc/nginx/conf.d/default.conf
Listen 8989;

Test the configuration of nginx before restarting the service of nginx

[root@linuxhelp ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

restart the service of Nginx to update the changes in the configuration of nginx

[root@linuxhelp ~]# systemctl restart nginx

Verify Nginx listening socket using netstat

 [root@linuxhelp ~]# netstat -tulpn | grep nginx
tcp        0      0 0.0.0.0:8989            0.0.0.0:*               LISTEN      32344/nginx: master 
tcp6       0      0 :::8989                 :::*                    LISTEN      32344/nginx: master
