Scope/Description

• This article will cover installing Houston UI for CentOS 7.

Prerequisites

• CentOS 7 installed

Steps

• First, we’ll update to the latest packages

[root@centos7-45d ~]# yum update -y

• Reboot after the update if there is a new kernel.
• Install epel-release.

[root@centos7-45d ~]# yum install epel-release -y

• Next, we’ll install the ZFS packages.

[root@centos7-45d ~]# yum install http://download.zfsonlinux.org/epel/zfs-release.el7_9.noarch.rpm

[root@centos7-45d ~]# yum install -y kernel-devel zfs

[root@centos7-45d ~]# echo zfs > /etc/modules-load.d/zfs.conf

[root@centos7-45d ~]# modprobe zfs

• Reboot to ensure ZFS loads correctly on startup.
• Set SELinux to permissive.

[root@centos7-45 ~]# setenforce 0

• To keep the permissive setting after reboot.

[root@centos7-45d ~]# sed -i 's/^\(SELINUX=\).*$/\1permissive/' /etc/selinux/config

• Pull down the 45drives Repository.

[root@centos7-45d ~]# curl -sSL https://repo.45drives.com/setup | sudo bash

• Install the following packages.

[root@centos7-45d ~]# yum install -y cockpit cockpit-pcp 45drives-tools

• Enable the cockpit socket.

[root@centos7-45d ~]# systemctl enable --now cockpit.socket

• Add a firewall rule for cockpit.

[root@centos7-45d ~]# firewall-cmd --permanent --add-port=9090/tcp; firewall-cmd --reload

• Install Houston UI modules.

[root@centos7-45d ~]# yum install -y cockpit-zfs-manager cockpit-45drives-hardware cockpit-file-sharing cockpit-navigator cockpit-benchmark cockpit-storaged

• Now, run dmap  to update the drive aliasing,. It should clearly display the installed drives in each slot and their identifiers using lsdev.

[root@centos7-45d ~]# dmap

• Now you can run “lsdev”.

[root@centos7-45d ~]# lsdev

Verification

• Houston should now be installed and reachable at serverip:9090 in any web browser.

Troubleshooting

• If Houston is inaccessible, ensure cockpit is running, then restart the service.

systemctl status cockpit
systemctl restart cockpit
