1.4. Port Information
Red Hat Gluster Storage Server uses the listed ports. Ensure that 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 and Red Hat Enterprise Linux 8, if default ports are not already in use by other services, 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=zone_name --add-port=port/protocol # firewall-cmd --zone=zone_name --add-port=port/protocol --permanent
For example:
# firewall-cmd --zone=public --add-port=5667/tcp # firewall-cmd --zone=public --add-port=5667/tcp --permanent
