+### Firewalld configuration fails on RHEL 9 due to file permissions
+
+When you install Redis Enterprise Software version 7.4.2 on RHEL 9, `firewalld` configuration fails to add the `redislabs` service if `/etc/firewalld/services/redislabs-clients.xml` and `/etc/firewalld/services/redislabs.xml` are owned by `redislabs` instead of `root`.
+
+As a workaround:
+
+1. Change the files' owner and group to `root`: 
+
+    ```sh
+    $ chown root:root /etc/firewalld/services/redislabs-clients.xml
+    $ chown root:root /etc/firewalld/services/redislabs.xml
+    ```
+
+1. Add the `redislabs` service to `firewalld`:
+
+    ```sh
+    $ systemctl daemon-reload
+    $ systemctl restart firewalls
+    $ /bin/firewall-cmd --add-service=redislabs
+    ```
