How to add a port to a service in firewalld

This post shows how to add port 5000 into filrewalld for Oracle Autonomous Health Framework (AHF) running on GI/RAC.

1. List existing services:
   # firewall-cmd –get-services
   
2. Add the port: If the service you want to modify already exists, use the following command to add the port: 
   
   # firewall-cmd –permanent –add-port=<port>/<protocol> –service=<service-name>
   eg.
   
   #firewall-cmd –permanent –add-port=5000/tcp –service=oracle_rac
   
3. Reload firewalld: After making changes, reload firewalld to apply the new configuration:
   
   # firewall-cmd –reload
   
4. Check the port added into service:
   
   # firewall-cmd –info-service=oracle_rac
   oracle_rac
   ports: 1521/tcp 5000/tcp
