Install Jenkins on AWS EC2

Jenkins is a self-contained Java-based program, ready to run out-of-the-box, with packages for Windows, Mac OS X and other Unix-like operating systems. As an extensible automation server, Jenkins can be used as a simple CI server or turned into the continuous delivery hub for any project.

Prerequisites

  1. EC2 Instance
    • With Internet Access
    • Security Group with Port 8080 open for internet
  2. Java v1.8.x

Install Java

  1. We will be using open java for our demo, Get the latest version from http://openjdk.java.net/install/

    yum install java-1.8*
#yum -y install java-1.8.0-openjdk-devel

  2. Confirm Java Version and set the java home

    java -version
find /usr/lib/jvm/java-1.8* | head -n 3
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-<Java version which seen in the above output>
export JAVA_HOME
PATH=$PATH:$JAVA_HOME
 # To set it permanently update your .bash_profile
vi ~/.bash_profile

    The output should be something like this,

    [root@~]# java -version
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)
