Here at LinuxAPT, we will look into how to install Rundeck on Ubuntu 20.04.

Steps to install Rundeck on Ubuntu 20.04

1. Perform System Update

Before performing the installation, update and upgrade the Ubuntu system to its latest index repository:

$ sudo apt update
$ sudo apt upgrade

2. Install Java on the system

Rundeck is a Java based application and to run the application we need a java 8 or java 11. Install JDK 11 using the following command:

$ sudo apt install openjdk-11-jre
$ java –version

3. Install Database (Mysql/Mariadb)

Rundeck can be installed with database MySQL/MariaDB, MS SQL, PostgreSQL and Oracle to store the data. In this example, we are going to use MariaDB.

Install dependency and MariaDB packages using the command:

$ sudo apt install software-properties-common mariadb-server mariadb-client

Then, Enable and start mariadb service:

$ sudo systemctl enable mariadb.service
$ sudo systemctl status mariadb.service

Once the MySQL/MariaDB is installed, run the following command to secure the database system:

$ sudo mysql_secure_installation

Now create a database and database user for Rundeck:

$ mysql -u root -p
MariaDB [(none)]> CREATE DATABASE rundeck_db;
MariaDB [(none)]> CREATE USER 'rundeck_user'@'localhost' IDENTIFIED BY 'my-strong-password';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON *.* TO 'rundeck_user'@'localhost' WITH GRANT OPTION;
MariaDB [(none)]> exit

Replace "my-strong-password" with your database password which will be used by the Rundeck application.

4. Install Rundeck on the system

The Rundeck application package is not available in Ubuntu 20.04 by default. We need to Create a repository file and append the following content in the file:

$ sudo nano /etc/apt/sources.list.d/rundeck.list

Then, Add the below lines to this file:

deb any main
deb-src any main

Save the file and exit.

Once the repository file is created, run the following command to import the repo signing key:

$ curl -L | sudo apt-key add -

Update the Ubuntu system to reflect the changes:

$ sudo apt update

Now install rundeck using the following command:

$ sudo apt install rundeck
