Open multiple firewall ports in CentOS7
You can always make a small script/one-liner:
#!/bin/bash
for i in 80 443 22 123 21 1337 31337
do
firewall-cmd --zone=public --add-port=${i}/tcp
done
If those open ports are in a range for example 2379-2385, you can do as follows:
firewall-cmd --zone=zone_name --add-port=2379-2385/tcp
To make it permanent add --permanent
option at end.
You can define a service from an xml file containing all the ports you need, add a service from it and then enable it. Create the service.xml file like so:
<?xml version="1.0" encoding="utf-8"?>
<service>
<port port="port1" protocol="proto1"/>
<port port="port2" protocol="proto2"/>
<port port="port3" protocol="proto3"/>
<port port="port4" protocol="proto4"/>
</service>
Add new service:
# firewall-offline-cmd --new-service-from-file=service.xml --name=My_Service
Reload firewall-cmd:
# firewall-cmd --reload
Then add your service:
# firewall-cmd --add-service My_Service
