Bash Script: SonarQube and Postgres database Setup for Code Analysis.

Here is a simple script to provision SonarQube and Postgres database on a ec2 instance for code analysis to streamline a DevOps process.

Create and open a file - and paste the code snippet below. Make sure to change the database password.

#!/bin/bash
sudo cp /etc/sysctl.conf /root/sysctl.conf_backup

# Modify Kernel System Limits for Sonarqube
    sudo sh -c 'cat <<EOF> /etc/sysctl.conf
    vm.max_map_count=262144
    fs.file-max=65536
    ulimit -n 65536
    ulimit -u 4096
EOF'
    sudo apt update -y
    sudo apt-get install openjdk-11-jdk -y

# Postgres Database installation and setup
    wget -q https://www.postgresql.org/media/keys/ACCC4CF8.asc -O - | sudo apt-key add -

    sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ $(lsb_release -cs)-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'
    sudo apt install postgresql postgresql-contrib -y

    sudo systemctl enable postgresql.service
    sudo systemctl start  postgresql.service
    sudo echo "postgres:admin123" | sudo chpasswd
    sudo runuser -l postgres -c "createuser sonar"
    sudo -i -u postgres psql -c "ALTER USER sonar WITH ENCRYPTED PASSWORD 'admin123';"
    sudo -i -u postgres psql -c "CREATE DATABASE sonarqube OWNER sonar;"
    sudo -i -u postgres psql -c "GRANT ALL PRIVILEGES ON DATABASE sonarqube to sonar;"
    sudo systemctl restart  postgresql

# Sonarqube installation and setup
    sudo mkdir /sonarqube/
    cd /sonarqube/
    sudo curl -O https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-8.3.0.34182.zip
    sudo apt-get install zip -y
    sudo unzip -o sonarqube-8.3.0.34182.zip -d /opt/
    sudo mv /opt/sonarqube-8.3.0.34182/ /opt/sonarqube
    sudo groupadd sonar
    sudo useradd -c "SonarQube - User" -d /opt/sonarqube/ -g sonar sonar

    sudo cp /opt/sonarqube/conf/sonar.properties /root/sonar.properties_backup
    sudo chown sonar:sonar /opt/sonarqube/ -R
    sudo sh -c 'cat <<EOF> /opt/sonarqube/conf/sonar.properties
    sonar.jdbc.username=sonar
    sonar.jdbc.password=admin123
    sonar.jdbc.url=jdbc:postgresql://localhost/sonarqube

    sonar.web.port=9000
    sonar.web.javaAdditionalOpts=-server
    sonar.search.javaOpts=-Xmx512m -Xms512m -XX:+HeapDumpOnOutOfMemoryError
    sonar.log.level=INFO
    sonar.path.logs=logs

# Setup Systemd service for Sonarqube
    sudo sh -c 'cat <<EOF> /etc/systemd/system/sonarqube.service

    After=syslog.target network.target

    [Service]

    ExecStart=/opt/sonarqube/bin/linux-x86-64/sonar.sh start
    ExecStop=/opt/sonarqube/bin/linux-x86-64/sonar.sh stop

    User=sonar
    Group=sonar
    Restart=always

    LimitNOFILE=65536
    LimitNPROC=4096

    [Install]
    WantedBy=multi-user.target
EOF'
# Enable and restart service
    sudo systemctl daemon-reload
    sudo systemctl enable sonarqube.service
    sudo systemctl start sonarqube.service
    sudo reboot

Give execute permission

chmod +x sonarqube_setup.sh

Run script

./sonarqube_setup.sh

After the script is completed, the instance takes couple of seconds to reboot. Verify the instance is ready by logging into the instance.

Make sure to open port 9000 to your IP address or Anywhere IP 0.0.0.0/0, depending on your internet setup in your security group.

Verify in the browser
