Easy Guide to Installing Jenkins on an AWS Machine

 

Prerequisites

To run Jenkins on AWS, your machine needs at least 256MB RAM and 1GB ROM.

Steps to Install Jenkins on AWS

1. Launch an AWS Linux Instance

  • Log into AWS.
  • Select a Linux machine.
  • Launch the instance.

2. Install Java

Jenkins requires Java to run. Follow these steps to install Java:

sudo apt update  # Update the machine with the latest packages
sudo apt install -y fontconfig openjdk-17-jre  # Install Java

3. Install Jenkins

Jenkins offers two types of releases:

Weekly Release

  • Contains the latest features but may have bugs.
  • Updates are frequent, which can be disruptive.

Long Term Support (LTS) Release

  • More stable, with updates every 12–13 weeks.

We will proceed with the LTS release:

Steps to Install Jenkins LTS:

  1. Download and add the Jenkins key:
sudo wget -O /usr/share/keyrings/jenkins-keyring.asc \
  https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key

Explanation:

  • wget: Downloads files from the internet.
  • -O: Saves the downloaded key to /usr/share/keyrings/jenkins-keyring.asc.

2. Add the Jenkins package repository:

echo "deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc]" \
  https://pkg.jenkins.io/debian-stable binary/ | sudo tee \
  /etc/apt/sources.list.d/jenkins.list > /dev/null

Explanation:

  • Adds the Jenkins repository to your system’s package source list.

3. Update the package list and install Jenkins:

  • sudo apt-get update # Update the system with the latest Jenkins packages sudo apt-get install -y jenkins # Install Jenkins

4. Check Jenkins status:

  • systemctl status jenkins # Verify if Jenkins is active

4. Configure Jenkins via GUI

  1. Open Port 8080:
  • Jenkins runs on port 8080.
  • In AWS, modify the security group to allow port 8080 from My IP.
  • This ensures only your IP can access Jenkins, enhancing security.

Note: For third-party access, consider setting up a firewall or WAF (Web Application Firewall).

2. Access Jenkins:

  • Open your browser and go to http://<your-ip>:8080 (e.g., 192.168.1.68:8080).

3. Unlock Jenkins:

  • Retrieve the initial admin password:
  • sudo cat /var/lib/jenkins/secrets/initialAdminPassword
  • Copy the password and paste it into the Jenkins interface.

4. Install Suggested Plugins:

  • Choose the option to install suggested plugins for easy integration with tools like Docker, GitHub, email, etc.

5. Set Up Admin User:

  • Provide the following details:
  • Username: admin
  • Password: test@1234
  • Full Name: Raees Qazi
  • Email: xyz@gmail.com

 Today, I am going to create a simple calculator using Python . This might be your first code ever , and honestly, this is also my first Python code . So don’t worry — we are learning together. Let’s start step by step. Step 1: Open VS Code First, open Visual Studio Code (VS Code) . Step 2: Create a Folder and a File Create a new folder (you can name it anything). Inside the folder, create a new file. In my case, I named the file first.py . 👉  .py is the file extension for Python , just like: .cpp for C++ .java for Java Step 3: Write the Python Code Now, write the following code in first.py : num1 = float ( input ( "Enter num 1: " ) ) # Taking first number from the user num2 = float ( input ( "Enter num 2: " ) ) # Taking second number from the user opr = input ( "Enter operator: " ) # User selects the operator (+, -, *) if opr = = "+" : # If operator is + output = num1 + num2 if opr = = "-" : # If operator is - ...
