Introduction
In this tutorial we learn how to install clusterssh on CentOS 8.
What is clusterssh
Control multiple terminals open on different servers to perform administration tasks, for example multiple hosts requiring the same configuration within a cluster. Not limited to use with clusters, however.
We can use yum or dnf to install clusterssh on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install clusterssh.
Install clusterssh on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
CentOS Linux 8 - AppStream 43 kB/s | 4.3 kB 00:00
CentOS Linux 8 - BaseOS 65 kB/s | 3.9 kB 00:00
CentOS Linux 8 - ContinuousRelease 43 kB/s | 3.0 kB 00:00
CentOS Linux 8 - Extras 23 kB/s | 1.5 kB 00:00
CentOS Linux 8 - FastTrack 40 kB/s | 3.0 kB 00:00
CentOS Linux 8 - HighAvailability 36 kB/s | 3.9 kB 00:00
CentOS Linux 8 - Plus 24 kB/s | 1.5 kB 00:00
CentOS Linux 8 - PowerTools 50 kB/s | 4.3 kB 00:00
Extra Packages for Enterprise Linux Modular 8 - x86_64 13 kB/s | 9.2 kB 00:00
Extra Packages for Enterprise Linux 8 - x86_64 24 kB/s | 8.5 kB 00:00
Metadata cache created.
After updating yum database, We can install clusterssh using dnf by running the following command:
sudo dnf -y install clusterssh
Install clusterssh on CentOS 8 Using yum

Extra Packages for Enterprise Linux 8 - x86_64 24 kB/s | 8.5 kB 00:00
Metadata cache created.
After updating yum database, We can install clusterssh using yum by running the following command:
sudo yum -y install clusterssh
How To Uninstall clusterssh on CentOS 8
To uninstall only the clusterssh package we can use the following command:
sudo dnf remove clusterssh
