Define a new service in firewalld

· 92 words · 1 minute read

If you want to create a new service definition (i.e. to group a few ports in the same service), the procedure will be:

  • Create a file called “myservice.xml” in /etc/firewalld/services/ folder with the following content:
<?xml version="1.0" encoding="utf-8"?>
    <description>Group httpd ports</description>  
    <port protocol="tcp" port="80"/>  
    <port protocol="tcp" port="443"/>  
    <port protocol="tcp" port="8080"/>  
    <port protocol="tcp" port="8000"/>  
  • Set permissions
restorecon /etc/firewalld/services/myservice.xml
chmod 640 /etc/firewalld/services/myservice.xml
  • Reload firewalld to force it to read the XML
firewall-cmd --reload
  • Add the RH-Satellite-6 service to the default zone
firewall-cmd --permanent --add-service=myservice
  • Reload firewalld just in case
firewall-cmd --reload
