Hello,

Please give me steps to open a port number on VPS/Server.

Before this step, I would check if that port is opening or closed then how?

Thank you in advance.

This will show open ports
netstat -lntu


This will work with CentOS 5 and older versions of debian

iptables -I INPUT -p tcp -m tcp --dport 80 -j ACCEPT
service iptables save

in this example port 80 is opened.

Yes it will be fine on CentOS 6. However it will not apply to CentOS 7 which uses systemD and firewallD which do work a little different.
