How to Install and Use Rundeck for Job Scheduling on Ubuntu
Rundeck is a powerful open-source tool that enables automation of tasks through job scheduling, making it an invaluable asset for system administrators and DevOps teams. In this guide, we will walk through the steps required to install Rundeck on an Ubuntu system and explore its basic functionalities for job scheduling.
Prerequisites
Before starting the installation, ensure you have the following prerequisites:
- Ubuntu Server: This guide is based on Ubuntu 20.04 LTS or later.
- Java: Rundeck requires Java to run. Make sure to install OpenJDK 11 or later.
- Root Access: You will need sudo privileges to install Rundeck and its dependencies.
Step 1: Install Java
First, you need to install Java. Open your terminal and run the following command:
sudo apt update
sudo apt install openjdk-11-jdk -y
To verify the installation, you can check the Java version:
java -version
You should see output similar to:
- openjdk version “11.0.11” 2021-04-20
- OpenJDK Runtime Environment (build 11.0.11+9-Ubuntu-0ubuntu2)
- OpenJDK 64-Bit Server VM (build 11.0.11+9-Ubuntu-0ubuntu2, mixed mode, sharing)
Step 2: Install Rundeck
Add Rundeck Repository
Rundeck is not available in the default Ubuntu repositories, so you need to add the Rundeck repository first. Use the following commands:
sudo wget https://packages.rundeck.org/deb/rundeck.gpg -O /etc/apt/trusted.gpg.d/rundeck.gpg
echo “deb https://packages.rundeck.org/deb/ubuntu focal main” | sudo tee /etc/apt/sources.list.d/rundeck.list
Update Package Index
Next, update the package index to include the newly added Rundeck repository:
sudo apt update
Now, install Rundeck with the following command:
sudo apt install rundeck -y
Start and Enable Rundeck Service
After installation, start the Rundeck service and enable it to start on boot:
sudo systemctl start rundeckd
sudo systemctl enable rundeckd
To check the status of the Rundeck service, use:
sudo systemctl status rundeckd
You should see an output indicating that the service is active and running.
Step 3: Configure Rundeck
Rundeck’s default configuration files are located in /etc/rundeck/. The main configuration file is rundeck-config.properties. You may want to configure some parameters based on your needs, such as the hostname or port number.
By default, Rundeck runs on port 4440. You can access the web interface by navigating to http://:4440 in your web browser.
Initial Setup
On your first visit to the Rundeck web interface, you will be prompted to create an admin user. Follow the on-screen instructions to set up your Rundeck instance.
