Linux ?


Linux is an operating system which was assembled under the model of free and open source software development and distribution. The main component of Linux is the Linux kernel, The first release of this Linux was done by Linus Torvalds in Oct 1991.

It was originally developed as a free operating system for Intel x86-based personal computers but now it supports nearly all the computer hardware's. Mainly it is used on servers, mainframes, supercomputers but now a days it is being heavily used in mobile devices some of the examples are Maemo, MeeGo, Android etc.

The development of Linux is one of the most prominent examples of free and open source software collaboration: the underlying source code may be used, modified, and distributed—commercially or non-commercially—by anyone under licenses such as the GNU General Public License.

Some of the Linux flavors are:

  • RHEL: Red Hat Enterprise Linux.
  • Suse.
  • Fedora.
  • Mandriva.
  • Debian.
  • Ubuntu.... and many more.

A Linux-based system is a modular Unix-like operating system. It derives much of its basic design from principles established in Unix during the 1970s and 1980s. Such a system uses a monolithic kernel, there are few other types of kernels present like microlithic (example: Windows) and Hybrid Kernel (example:Mac OS).

In this blog we will basically talk about RHEL i.e. Red Hat Enterprise Linux.

Installing Tomcat8 on RHEL6

Image
Apache-HTTP v/s Apache-Tomcat: The basic difference is Apache-Tomcat is written in Java but Apache-HTTP is written in C. Apart from this Apache-Tomcat is used as a webserver as well as to deploy Java Servlet's and JSP's [Java server pages] so basically Apache-Tomcat is used to serve Java Technologies whereas Apache-HTTP is used to serve HTTP. Prerequisites: Appropriate version of JRE [Java run-time environment] for instance jre1.7 is required to run tomcat-8[.X.X]. Tomcat binaries, for version 8 check this link . Sudo/Root access to the machine. Step1: Install JRE Download JRE from Java's official website. You can keep Java at any location but for my ease I have kept both Tomcat and Java in /opt. # cd /opt # cp jre-7u45-linux-x64.tar.gz . # tar -zxvf jre-7u45-linux-x64.tar.gz  The above command will create a folder with JRE binaries. In my case it was "jre1.7.0_45". Now set JRE_HOME [Required by Tomcat] and PATH. export JRE_HOME=/opt/jre1.7.

Manage existing resources via Helm

Manage existing resources via Helm Helm is really a very powerful tool for managing Kubernetes objects. With a single command, we can install or upgrade multiple related Kubernetes entities. Let's say we want to install any chart from the helm registry, we just need to type in the below command and helm will do the heavy lifting for us. $ helm install [RELEASE_NAME] [REPO]/[CHART] But below post is not about the basics of helm or how to install or upgrade a chart, etc. It's been a long time since I wrote anything, so I just thought to write something about what new I learned today :)  While installing one of my charts, I encountered below issue: Error: INSTALLATION FAILED: rendered manifests contain a resource that already exists. Unable to continue with install: StorageClass "demo-sc" in namespace "" exists and cannot be imported into the current release: invalid ownership metadata; label validation error: missing key "app.kubernetes.io/managed-by&qu
