Chapter 4. Getting Started with Red Hat Gluster Storage Server

This chapter provides information on the ports that must be open for Red Hat Gluster Storage Server and the glusterd service.
The Red Hat Gluster Storage glusterFS daemon glusterd enables dynamic configuration changes to Red Hat Gluster Storage volumes, without needing to restart servers or remount storage volumes on clients.

4.1. Port Information

Red Hat Gluster Storage Server uses the listed ports. You must ensure that the firewall settings do not prevent access to these ports.
Firewall configuration tools differ between Red Hat Entperise Linux 6 and Red Hat Enterprise Linux 7.
For Red Hat Enterprise Linux 6, use the iptables command to open a port:
# iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 5667 -j ACCEPT
# service iptables save
For Red Hat Enterprise Linux 7, if default ports are in use, it is usually simpler to add a service rather than open a port:
# firewall-cmd --zone=zone_name --add-service=glusterfs 
# firewall-cmd --zone=zone_name --add-service=glusterfs --permanent
However, if the default ports are already in use, you can open a specific port with the following command:
# firewall-cmd --zone=public --add-port=5667/tcp
# firewall-cmd --zone=public --add-port=5667/tcp --permanent

Port Number Usage
22 For sshd used by geo-replication.
111 For rpc port mapper.
139 For netbios service.
445 For CIFS protocol.
965 For NFS's Lock Manager (NLM).
2049 For glusterFS's NFS exports (nfsd process).
24007 For glusterd (for management).
24009 - 24108 For client communication with Red Hat Gluster Storage 2.0.
38465 For NFS mount protocol.
38466 For NFS mount protocol.
38468 For NFS's Lock Manager (NLM).
38469 For NFS's ACL support.
