How to Install GlusterFS on CentOS 7

GlusterFS packages are not included in the default CentOS 7 repository so the packages can be installed from Gluster repository and EPEL repository. GlusterFS packages needs to install on all the GlusterFS Nodes.

This article describes How to Install GlusterFS on CentOS 7.

 

Step 1. Enable EPEL Repository: Follow the article How to install EPEL repository on Centos7 to enable/install EPEL Repository as some dependencies are required from EPEL repository to run GlusterFS Server. It should be enabled on all the GlusterFS nodes.

 

Step 2. Enable Gluster Repository: Run the following commands on all the nodes to enable GlusterFS repository:

 

[root@linuxcnf ~]# yum install centos-release-gluster Loaded plugins: fastestmirror ……………………. Installed:   centos-release-gluster9.noarch 0:1.0-1.el7   Dependency Installed:   centos-release-storage-common.noarch 0:2-2.el7.centos   Complete! [root@linuxcnf ~]#

 

Step 3. GlusterFS Packages Installation: Run the below commands to install GlusterFS and related packages:

 

[root@linuxcnf ~]# yum install glusterfs-server Loaded plugins: fastestmirror ……………………. Installed:   glusterfs-server.x86_64 0:9.6-1.el7   Dependency Installed:   attr.x86_64 0:2.4.46-13.el7            glusterfs.x86_64 0:9.6-1.el7 ……………………. userspace-rcu.x86_64 0:0.10.0-3.el7   Complete! [root@linuxcnf ~]#

 

Step 5. Firewall Configuration: By default, glusterd will listen on tcp/24007 but opening that port is not enough on the gluster nodes. Each time new bricks addition will open a new port so would need to either disable the firewall or configure the firewall to allow all connections on all cluster nodes.

 

[root@linuxcnf ~]# systemctl disable firewalld --now Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service. [root@linuxcnf ~]#

 

Step 4. Start GlusterFS: Run the following command to start Spacewalk service and enable it across reboot:

[root@linuxcnf ~]# systemctl enable glusterd –now Created symlink from /etc/systemd/system/multi-user.target.wants/glusterd.service to /usr/lib/systemd/system/glusterd.service. [root@linuxcnf ~]#

 

Run the following command to verify the service status:

 

[root@linuxcnf ~]# systemctl status glusterd ● glusterd.service - GlusterFS, a clustered file-system server    Loaded: loaded (/usr/lib/systemd/system/glusterd.service; enabled; vendor preset: disabled)    Active: active (running) since Thu 2022-09-22 07:47:38 IST; 13s ago      Docs: man:glusterd(8)   Process: 1972 ExecStart=/usr/sbin/glusterd -p /var/run/glusterd.pid --log-level $LOG_LEVEL $GLUSTERD_OPTIONS (code=exited, status=0/SUCCESS)  Main PID: 1973 (glusterd)    CGroup: /system.slice/glusterd.service            └─1973 /usr/sbin/glusterd -p /var/run/glusterd.pid --log-level INFO   Sep 22 07:47:38 linuxcnf systemd[1]: Starting GlusterFS, a clustered file-system server... Sep 22 07:47:38 linuxcnf systemd[1]: Started GlusterFS, a clustered file-system server. [root@linuxcnf ~]#

 

Done!!! GlusterFS installation successfully completed on CentOS 7.
