yum is for CentOS and Redhat.
apt-get is for Debian and Ubuntu.
In the same way, zypper is for SUSE Linux.
Zypper is a command line tool for package management in OpenSUSE and SUSE Enterprise Linux platforms.
In the first part, we explained in detail on how to install and configure 2 Node RedHat Cluster.
We covered the following high-level steps in the previous tutorial:
In this tutorial, we’ll cover the following high-level steps to finish the cluster setup:
In an active-standby Linux cluster configuration, all the critical services including IP, filesystem will failover from one node to another node in the cluster.
This tutorials explains in detail on how to create and configure two node redhat cluster using command line utilities.
The following are the high-level steps involved in configuring Linux cluster on Redhat or CentOS:
In our previous article of Linux KVM series, we explained how to Install Linux KVM and create a Guest VM.
But, once you’ve created a Guest VM, you need to know how to perform some of the routine maintenance activities on the VM.
This tutorial will explain how to perform the following Linux KVM VM activities:
Sometimes you might have access to an open source application source code but might not have the RPM file to install it on your system.
In that situation, you can either compile the source code and install the application from source code, or build a RPM file from source code yourself, and use the RPM file to install the application.
There might also be a situation where you want to build a custom RPM package for the application that you developed.
This tutorial explains how to build a RPM package from the source code.
LDAP stands for Lightweight Directory Access Protocol.
LDAP is a solution to access centrally stored information over network. This centrally stored information is organized in a directory that follows X.500 standard.
The information is stored and organized in a hierarchical manner and the advantage of this approach is that the information can be grouped into containers and clients can access these containers whenever needed.
The OpenLDAP hierarchy is almost similar to the DNS hierarchy.
This tutorial explains the process of building useful multi-part commands piece by piece.
To build complex commands in the terminal, we need to understand piping. Piping is basically taking the output of one command and sending it to another command as input. This is done with the | (pipe) symbol.
Last month, a small project required me to repeatedly read similar XML files to provide test data for another program. I would have to do it so frequently that it would be annoying to have to download, save, parse and repeat. The basic requirements were:
