Rundeck is all about ....!


Well, Rundeck is open source software that helps you automate routine operational procedures in data center or cloud environments, it allows you to run tasks on any number of nodes from a web-based or command-line interface.

Rundeck also includes other features that make it easy to scale up your automation efforts including: access control, workflow building, scheduling, logging, and integration with external sources for node and option data. Refer introduction and essential-concepts URL for more details.

Pre-requirements and preparing the server to install rundeck:


The following operating systems are known to support Rundeck:

  • Linux: Most recent distributions are likely to work
  • Windows: XP, Server and above
  • Mac OS X 10.4 or later 
     
Root (or Administrator on Windows) is not required or recommended. We recommend using a dedicated user account such as "rundeck". If there is need for root access, please set up the Rundeck user to have access via sudo.

step1 - Install java:


java JDK must be installed. Install any JDK that is 1.7+.

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

Add the below contents into file: /etc/profile.d/java.sh
#!/bin/bash
