DevOps Tools Installation Manuals

My installation guides and bash scripts for essential DevOps tools like Jenkins (CI/CD), Nexus (artifact repository), SonarQube (code analysis), Docker (containerization), Trivy (vulnerability scanning), etc... on Ubuntu Based Server like EC2, Droplet, Linode.

Single Command Installation Guide:

To install tools on your Ubuntu server, navigate to your server environment. Copy and paste the following command into your terminal. These commands will automatically download the installation script, grant it execution permissions, and initiate the installation process.

For Jenkins:

wget https://raw.githubusercontent.com/akiltipu/devops-tools-installation-manuals/main/install_jenkins_on_ubuntu.sh
chmod +x install_jenkins_on_ubuntu.sh
./install_jenkins_on_ubuntu.sh

For Nexus:

wget https://raw.githubusercontent.com/akiltipu/devops-tools-installation-manuals/main/install_nexus_on_ubuntu.sh
chmod +x install_nexus_on_ubuntu.sh
./install_nexus_on_ubuntu.sh

For SonarQube:

wget https://raw.githubusercontent.com/akiltipu/devops-tools-installation-manuals/main/install_SonarQube_on_ubuntu.sh
chmod +x install_SonarQube_on_ubuntu.sh
./install_SonarQube_on_ubuntu.sh

For Docker and Docker Compose:

wget https://raw.githubusercontent.com/akiltipu/devops-tools-installation-manuals/main/install_docker_dockercompose.sh
chmod +x install_docker_dockercompose.sh
./install_docker_dockercompose.sh

For Terraform:

wget https://raw.githubusercontent.com/akiltipu/devops-tools-installation-manuals/main/install_terraform_ubuntu.sh
chmod +x install_terraform_ubuntu.sh
./install_terraform_ubuntu.sh

To access a comprehensive installation guide with detailed instructions, please expand the dropdown below

Install Jenkins on Ubuntu Server

Update the package list

sudo apt update

Add Jenkins repository key

sudo wget -O /usr/share/keyrings/jenkins-keyring.asc \
https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key

Then add a Jenkins apt repository entry:

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

Update the package list

sudo apt update

Install Java (Jenkins requires Java)

sudo apt-get install fontconfig openjdk-17-jre -y

Add Jenkins repository to sources list

echo "deb http://pkg.jenkins.io/debian-stable binary/" | sudo tee -a /etc/apt/sources.list.d/jenkins.list

Update package list again to include Jenkins repository

sudo apt update

Install Jenkins

sudo apt install -y jenkins

Start Jenkins service

sudo systemctl start jenkins

Enable Jenkins to start on boot

sudo systemctl enable jenkins

Display initial Jenkins admin password

echo "Waiting for Jenkins to start..."
sleep 60 # Wait for Jenkins to fully start (adjust if needed)

Retrieve the initial admin password

JENKINS_PASSWORD=$(sudo cat /var/lib/jenkins/secrets/initialAdminPassword)
echo "Jenkins initial admin password: $JENKINS_PASSWORD"
echo "Access Jenkins at http://your-server-ip:8080"

Open the firewall to allow access to Jenkins

sudo ufw allow 8080

Display Jenkins status

sudo systemctl status jenkins | cat
Install Nexus Artifact Repository on Ubuntu Server

Create Ubuntu Server (Droplet) - min 4GB RAM & 2 CPUs Open SSH port 22, 8081

Nexus Installation Guide on Ubuntu

Update the package list:

sudo apt update

Install OpenJDK 8:

sudo apt install openjdk-8-jre-headless

Install net-tools:

sudo apt install net-tools

Navigate to the /opt directory:

cd /opt

Download and extract Nexus:

sudo wget https://download.sonatype.com/nexus/3/latest-unix.tar.gz
sudo tar -zxvf latest-unix.tar.gz

Create a Nexus user:

sudo adduser nexus

Set ownership for Nexus directories:

sudo chown -R nexus:nexus nexus-3.28.1-01
sudo chown -R nexus:nexus sonatype-work

Edit Nexus runtime configuration:

sudo vim nexus-3.28.1-01/bin/nexus.rc

Inside nexus.rc, set the run_as_user variable to "nexus".

run_as_user="nexus"

Save and exit the editor.

Switch to the Nexus user:

sudo su - nexus

Start Nexus:

/opt/nexus-3.28.1-01/bin/nexus start

Check Nexus process status:

ps aux | grep nexus

Check Nexus port status:

netstat -lnpt

Now, Nexus should be up and running on your Ubuntu system. You can access the Nexus web interface by navigating to http://your_server_ip:8081 in a web browser.

Install SonarQube on Ubuntu Server

Pull SonarQube Image:

    docker pull sonarqube

Create Docker Network:

    docker network create sonar-network

Run PostgreSQL Database Container:

    docker run -d --name sonar-db --network sonar-network \
    -e POSTGRES_USER=sonar \
    -e POSTGRES_PASSWORD=sonar \
    -e POSTGRES_DB=sonar \
    postgres:9.6
  • -d: Detached mode, run container in the background.
  • --name sonar-db: Assign a name to the container.
  • --network sonar-network: Connect container to the created network.
  • -e POSTGRES_USER=sonar: Set PostgreSQL username to 'sonar'.
  • -e POSTGRES_PASSWORD=sonar: Set PostgreSQL password to 'sonar'.
  • -e POSTGRES_DB=sonar: Create a database named 'sonar' in PostgreSQL.

Run SonarQube Container:

    docker run -d --name sonar -p 9000:9000 --network sonar-network \
    -e SONARQUBE_JDBC_URL=jdbc:postgresql://sonar-db:5432/sonar \
    -e SONAR_JDBC_USERNAME=sonar \
    -e SONAR_JDBC_PASSWORD=sonar \
    sonarqube
  • -d: Detached mode, run container in the background.
  • --name sonar: Assign a name to the SonarQube container.
  • -p 9000:9000: Map container's port 9000 to host's port 9000.
  • --network sonar-network: Connect container to the created network.
  • -e SONARQUBE_JDBC_URL=jdbc:postgresql://sonar-db:5432/sonar: Set JDBC URL to connect SonarQube to the PostgreSQL database.
  • -e SONAR_JDBC_USERNAME=sonar: Set SonarQube's database username.
  • -e SONAR_JDBC_PASSWORD=sonar: Set SonarQube's database password.

Access SonarQube:

After running the container, you can access SonarQube by navigating to http://localhost:9000 in your web browser. The default credentials are:

  • Username: admin
  • Password: admin

This setup will allow you to use SonarQube for static code analysis on your projects with the PostgreSQL database backend.
