Installing and Configuring Rundeck

Rundeck

You’re either the one that creates the automation or you’re getting automated…

Rundeck is open-source software that helps you automate and schedule routine operational procedures in your environment may that be On-Premisses or Cloud-based.

Some Rundeck features

  • Scheduled or On-demand (Web GUI, CLI or API WebHooks) job execution
  • Pluggable execution system (SSH and WinRM by default; Powershell available)
  • Secure Key store for passwords and keys
  • Role-based access control policy with support for LDAP/ActiveDirectory and other SSO
  • Access control policy editing/management tools
  • History and auditing logs
  • Use any scripting language
  • GIT and Other SCM Support

Rundeck is great if you need a GUI tool instead of Crons. At least that’s how I have configured most of my jobs in Rundeck. It also supports PowerShell execution by using the WinRM module.

I’ve got tons of jobs configured to submit AD reports, Database logs and Server Logs to audit every month for review. Taking periodical device config backups, Restarting servers running on Vmware and more. This saved me a hefty amount of time. Best of all is even though there is an Enterprise paid version Community Open source Rundeck is more than enough for those jobs.

Sometimes you may have to get creative like using PowerShell PowerCli to execute Vmware jobs instead of purchasing the enterprise version for the VMware plugin. But there is a way always.

Also, if you are able to buy the Enterprise version. Do it. It’s worth it.

Prerequisites

( It will work out of the box with h2 database. But its not recommended for production environment. If you are just testing this out go ahead and skip to the Rundeck installation part)

Install and Configure Rundeck

Setup repos and install rundeck

rpm -Uvh http://repo.rundeck.org/latest.rpm
sudo yum install rundeck java

Rundeck by default only allow traffic from local host. We need to change that if you need to access it from elsewhere.

cd /etc/rundeck/
vim rundeck-config.properties

Edit Below line with your own server IP.

grails.serverURL=http://localhost:4440

TO

grails.serverURL=http://192.168.2.229:4440

Lets Configure Rundeck to use Mysql Database (Skip to Rundeck Restart part if you choose not to have external Database)

In the same config file. Change below values as you defined earlier if you have changed them

dataSource.dbCreate = update
dataSource.url = jdbc:h2:file:/var/lib/rundeck/data/rundeckdb;MVCC=true

To

datasource rundeck config database mysql
dataSource.dbCreate = update
dataSource.url = jdbc:mysql://localhost/rundeck?autoReconnect=true&useSSL=false
dataSource.username=rundeckuser
dataSource.password=rundeckpassword
dataSource.driverClassName=org.mariadb.jdbc.Driver

Save it with Esc -> !wq -> Enter

Restart the Rundeck Service

service rundeckd restart

Navigate to YourserverIP:4440 using your browser

Voila!!!
