Being used to have Cockpit in my Fedora 21 Server VMs I decided that having it also on my CentOS machines would be awesome, unfortunately I quickly found that Cockpit was not available in CentOS repositories. Of course I knew that Cockpit comes installed and enabled by default in CentOS 7 Atomic host image so I figured out that those packages had to be hidden in some Atomic related repo.
After looking a bit I finally found in GitHub the sig-atomic-buildscripts repository that belongs to CentOS Project. This repository contains several scripts and files intended to build your own CentOS Atomic host including
virt7-testing.repo, the Yum repository file needed for Cockpit.
Clone the GutHub repository.
git clone https://github.com/baude/sig-atomic-buildscripts
virt7-testing.repo file to
/etc/yum.repos.d and install Cockpit.
yum install cockpit
Enable Cockpit service.
[root@webtest ~]# systemctl enable cockpit.socket ln -s '/usr/lib/systemd/system/cockpit.socket' '/etc/systemd/system/sockets.target.wants/cockpit.socket' [root@webtest ~]#
Add Cockpit to the list of trusted services in FirewallD.
[root@webtest ~]# firewall-cmd --permanent --zone=public --add-service=cockpit success [root@webtest ~]# [root@webtest ~]# firewall-cmd --reload success [root@webtest ~]# [root@webtest ~]# firewall-cmd --list-services cockpit dhcpv6-client ssh [root@webtest ~]#
Start Cockpit socket.
systemctl start cockpit.socket
Do no try to access Cockpit yet, there is an issue about running Cockpit on stock CentOS/RHEL 7. To be able to start it we need first to modify the service file to disable SSL. Edit file
/usr/lib/systemd/system/cockpit.service and modify
ExecStart line to look like this.
I know this procedure will invalidate Cockpit for a production environment in RHEL7 at least for now but this is for my lab environment and I can live with it.
systemctl restart cockpit
Access Cockpit web interface, login as root and have fun :-)
