Automate the provisioning of two Ubuntu-based servers, named “Master” and “Slave”, using Vagrant. On the Master node, create a bash script to automate the deployment of a LAMP (Linux, Apache, MySQL, PHP) stack. This script should clone a PHP application from GitHub, install all necessary packages, and configure Apache web server and MySQL. Ensure the bash script is reusable and readable. Using an Ansible playbook: Execute the bash script on the Slave node and verify that the PHP application is accessible through the VM’s IP address (take screenshot of this as evidence) Create a cron job to check the server’s uptime every 12 am.
To accomplish the objective, we'll follow these steps:
Set up two Ubuntu-based servers named "Master" and "Slave" using Vagrant. Create a bash script to automate the deployment of a LAMP stack on the Master node. Use an Ansible playbook to execute the bash script on the Slave node and verify the accessibility of a PHP application. Create a cron job to check the server's uptime every day at 12 am on the Slave node. Let's start with step-by-step implementation:
Step 1: Set up the servers using Vagrant
Ensure you have Vagrant installed on your system. Then, create a Vagrantfile with the following configuration:
Step 2: Create a bash script for LAMP stack deployment on the Master node Create a bash script named automate.sh
Purpose:
This script automates the process of setting up a Laravel application on a Linux system with Apache web server and a MySQL database.
Steps:
System Updates and Package Installation:
Updates the package lists (sudo apt update -y). Installs Apache web server (sudo apt install apache2 -y). Adds the Ondřej repository for PHP 8.2 (sudo add-apt-repository ppa:ondrej/php -y). Updates the package lists again (sudo apt update -y). Installs PHP 8.2 (sudo apt install php8.2 -y). Installs necessary PHP dependencies for Laravel (sudo apt install php8.2-curl php8.2-dom php8.2-mbstring php8.2-xml php8.2-mysql). Apache Configuration:
Enables Apache rewrite module (sudo a2enmod rewrite). Restarts Apache server (sudo systemctl restart apache2). Composer Installation:
Installs Composer globally (install composer globally -y). (Note: This line might need modification depending on your system's package manager.) Downloads Composer installer (sudo curl -sS https://getcomposer.org/installer | sudo php -q). Moves the downloaded installer to composer (sudo mv composer.phar composer). Laravel Project Setup:
Navigates to the /var/www directory (cd /var/www/). Clones the Laravel repository from GitHub (sudo git clone https://github.com/laravel/laravel.git). Sets ownership of the Laravel directory to the current user (sudo chown -R $USER:$USER /var/www/laravel). Navigates to the Laravel project directory (cd laravel/). Installs Composer dependencies in production mode (composer install --optimize-autoloader --no-dev --no-interaction). Updates Composer dependencies (composer update --no-interaction). Copies the .env.example file to .env (sudo cp .env.example .env). Sets ownership of storage and bootstrap/cache directories to the web server user (sudo chown -R www-data storage sudo chown -R www-data bootstrap/cache). Apache Virtual Host Configuration:
Creates a new virtual host configuration file (sudo touch latest.conf).
Defines the virtual host configuration for the Laravel application (sudo echo ... | sudo tee /etc/apache2/sites-available/latest.conf). This configuration includes:
Server name: localhost Document root: /var/www/laravel/public AllowOverride All for the Laravel directory Error logs and access logs Enables the new virtual host (sudo a2ensite latest.conf).
Disables the default virtual host (sudo a2dissite 000-default.conf).
Restarts Apache server (sudo systemctl restart apache2).
MySQL Database Setup:
Installs MySQL server (sudo apt install mysql-server -y). Installs MySQL client (sudo apt install mysql-client -y). Starts the MySQL service (sudo systemctl start mysql). Creates a MySQL database named goodydb (sudo mysql -uroot -e "CREATE DATABASE goodydb;"). Creates a MySQL user coder29 with the password secured23 (sudo mysql -uroot -e "CREATE USER 'coder29'@'localhost' IDENTIFIED BY 'secured23';"). Grants all privileges on the goodydb database to the user coder29 (sudo mysql -uroot -e "GRANT ALL PRIVILEGES ON goodydb.* TO 'coder29'@'localhost';"). Laravel Application Configuration:
Navigates to the Laravel project directory (cd /var/www/laravel). Updates the .env file with the following changes using sed: Enables MySQL database connection (sudo sed -i '22 s/=sqlite/=mysql/' /var/www/laravel/.env). Updates database host to localhost (sudo sed -i '23 s/=127.0.0.1/=localhost/' /var/www/laravel/.env). Keeps the default port (3306)
Step 3: Create an Ansible playbook to execute the bash script on the Slave node Create an Ansible playbook named deploy.yml with the following content: Step 4: Ping the slave sever to ensure connect with slave
Step 4: Verify PHP application accessibility and take a screenshot as evidence
Access the PHP application through the Slave node's IP address using a web browser.
