Centos7 – How to allow port in firewall
For allowing port on centos7 use this commands (1234 is new port):
firewall-cmd --zone=public --add-port=1234/tcp --permanent
and reload firewall:
firewall-cmd –reload
Warning: Any port is ruled with selinux. When you will make quick test with selinux start and stop use this command dor stop selinux:
setenforce 0
and this for selinux start:
setenforce 1
You don’t have to specify the zone. If you omit the ‚–zone=public‘ you’ll open the port in default zone, which is what you want in most cases.
