$ sudo systemctl enable apache2

On CentOS/Fedora

$ sudo systemctl start httpd
$ sudo systemctl enable httpd

Verify the installation by opening your web browser and navigating to http://localhost. You should see the Apache default welcome page.

Installing MySQL

If your application requires a database, you can install MySQL or MariaDB. Here, we will use MySQL.

On Ubuntu/Debian

$ sudo apt update
$ sudo apt install mysql-server -y

On CentOS/Fedora

$ sudo yum install mysql-server -y

Start and enable MySQL to run on boot:

On Ubuntu/Debian

$ sudo systemctl start mysql
$ sudo systemctl enable mysql

On CentOS/Fedora

$ sudo systemctl start mysqld
$ sudo systemctl enable mysqld

Secure your MySQL installation:

$ sudo mysql_secure_installation

Follow the prompts to set up a root password and secure the installation.

Installing Composer

Composer is a dependency manager for PHP that will help you manage your project’s libraries and dependencies.

On Ubuntu/Debian and CentOS/Fedora

$ php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
$ php -r "if (hash_file('SHA384', 'composer-setup.php') === file_get_contents('https://composer.github.io/installer.sig')) { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
$ php composer-setup.php
$ sudo mv composer.phar /usr/local/bin/composer

Verify the installation by checking the Composer version:

$ composer --version

3. Setting Up the Environment

Before installing Zend Framework / Laminas, it is crucial to ensure that your PHP environment is configured correctly. This includes setting up the appropriate PHP modules and configuring your PHP settings.

PHP Configuration

Edit the PHP configuration file (php.ini):

On Ubuntu/Debian

$ sudo nano /etc/php/7.4/apache2/php.ini

On CentOS/Fedora

$ sudo nano /etc/php.ini

Ensure the following settings are configured correctly:

memory_limit = 256M
post_max_size = 50M
upload_max_filesize = 50M
max_execution_time = 300

Save and exit the editor, then restart Apache to apply the changes:

On Ubuntu/Debian

$ sudo systemctl restart apache2

On CentOS/Fedora

$ sudo systemctl restart httpd

4. Installing Zend Framework / Laminas

With Composer installed, you can now install Zend Framework / Laminas. Zend Framework is now part of the Laminas Project, so you’ll install Laminas instead.

Installing Laminas via Composer

First, navigate to the directory where you want to create your Zend Framework / Laminas project:

$ cd /var/www/html

Use Composer to create a new Laminas project:

$ composer create-project laminas/laminas-mvc-skeleton my-zend-app

This command will download the Laminas MVC Skeleton application and install all the necessary dependencies. Once the installation is complete, you will have a basic Laminas application setup in the my-zend-app directory.

5. Configuring Apache

To serve your Laminas application using Apache, you need to configure a virtual host.

Creating a Virtual Host

Create a new Apache configuration file for your application:

On Ubuntu/Debian

$ sudo nano /etc/apache2/sites-available/my-zend-app.conf

On CentOS/Fedora

$ sudo nano /etc/httpd/conf.d/my-zend-app.conf

Add the following configuration to the file:

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html/my-zend-app/public
    ServerName my-zend-app.local
    <Directory /var/www/html/my-zend-app/public>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
    ErrorLog ${APACHE_LOG_DIR}/my-zend-app_error.log
    CustomLog ${APACHE_LOG_DIR}/my-zend-app_access.log combined
    <IfModule mod_rewrite.c>
        RewriteEngine On
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteRule ^ index.php [QSA,L]
    </IfModule>
</VirtualHost>

Save and close the file.

Enabling the Virtual Host

On Ubuntu/Debian

$ sudo a2ensite my-zend-app
$ sudo systemctl reload apache2

On CentOS/Fedora

$ sudo systemctl restart httpd

Modifying the Hosts File

To access your application via my-zend-app.local, you need to add an entry to your /etc/hosts file:

$ sudo nano /etc/hosts

Add the following line:

127.0.0.1   my-zend-app.local

Save and close the file.

6. Creating a New Zend Framework / Laminas Project

Now that your environment is set up and Apache is configured, you can start creating your Zend Framework / Laminas project. The Laminas MVC Skeleton application comes with a basic setup that you can extend and customize.

Creating Controllers

Controllers are responsible for handling user input and returning responses. To create a new controller, use the Laminas CLI tool:

$ cd /var/www/html/my-zend-app
$ composer require laminas/laminas-cli
$ ./vendor/bin/laminas mvc:controller MyController

This command creates a new controller named MyController. You can find it in the module/Application/src/Controller directory.

Creating Views

Views are used to generate the output sent to the user’s browser. Create a new view script for your controller action by creating a new file:

$ nano module/Application/view/application/my/index.phtml

Add the following content to this file:

<h1>Hello, Zend Framework!</h1>
<p>Welcome to your first Laminas application.</p>

Configuring Routes

Routes define the URLs that your application can respond to. Open the module/Application/config/module.config.php file and add a new route for your controller:

'router' => [
    'routes' => [
        'my' => [
            'type'    => Segment::class,
            'options' => [
                'route'    => '/my[/:action]',
                'defaults' => [
                    'controller' => ControllerMyController::class,
                    'action'     => 'index',
                ],
            ],
        ],
    ],
],

Save and close the file.

7. Running Your First Zend Framework / Laminas Application

Now that you have created a controller, a view, and configured a route, you can run your application and verify that everything is working correctly.

Starting Apache

Ensure that Apache is running:

On Ubuntu/Debian

$ sudo systemctl start apache2

On CentOS/Fedora

$ sudo systemctl start httpd

Accessing Your Application

Open your web browser and navigate to http://my-zend-app.local/my/index. You should see the welcome message you added in your view.

8. Common Issues and Troubleshooting

Database Connection Issues

If your application requires a database connection and you are experiencing issues, verify your database connection settings in the configuration file. Ensure that the username, password, and database name are correct.

Controller or View Errors

If you are encountering errors with your controller or view, check the Apache error log for more details. You can find the error logs at:

/var/log/apache2/error.log (Ubuntu/Debian)
/var/log/httpd/error_log (CentOS/Fedora)

Dependency Loading Issues

If you face issues with loading dependencies using Composer, ensure that you have an active internet connection and that Composer is correctly set up. You can try updating your dependencies with the following command:

$ composer update

Permission Issues

If you encounter permission issues when accessing your application files or directories, ensure that the Apache user has the necessary permissions. For most distributions, the Apache user is www-data on Ubuntu/Debian and apache on CentOS/Fedora. You can adjust the permissions with the following commands:

On Ubuntu/Debian

$ sudo chown -R www-data:www-data /var/www/html/my-zend-app
$ sudo chmod -R 755 /var/www/html/my-zend-app

On CentOS/Fedora

$ sudo chown -R apache:apache /var/www/html/my-zend-app
$ sudo chmod -R 755 /var/www/html/my-zend-app

Alternative Solutions for Installing and Running Zend Framework / Laminas

While the provided method using Composer and manual Apache configuration is a standard and reliable approach, here are two alternative methods for installing and running Zend Framework / Laminas applications on Linux:

1. Using Docker and Docker Compose:

Docker allows you to containerize your application and its dependencies, creating a consistent environment across different systems. Docker Compose simplifies the process of managing multi-container Docker applications.

Explanation:

This method involves creating a Dockerfile that defines the environment for your Zend Framework / Laminas application (including PHP, Apache, and any required extensions). A docker-compose.yml file then orchestrates the building and running of the container, including setting up volumes for code and database connections. This approach ensures consistency and eliminates dependency conflicts between different projects on the same server. It also makes deployment much simpler.

Code Example (Simplified Dockerfile):

FROM php:7.4-apache

# Install necessary extensions
RUN apt-get update && apt-get install -y 
    git 
    zip 
    unzip 
    libpng-dev 
    libjpeg62-turbo-dev 
    libfreetype6-dev 
    && docker-php-ext-configure gd --with-freetype --with-jpeg 
    && docker-php-ext-install -j $(nproc) gd pdo pdo_mysql zip

# Install Composer
COPY --from=composer:latest /usr/bin/composer /usr/local/bin/composer

# Set working directory
WORKDIR /var/www/html

# Copy application code
COPY . .

# Install dependencies
RUN composer install --no-dev --optimize-autoloader

# Set document root
ENV APACHE_DOCUMENT_ROOT /var/www/html/public
RUN sed -ri -e 's!/var/www/html!${APACHE_DOCUMENT_ROOT}!g' /etc/apache2/sites-available/*.conf
RUN sed -ri -e 's!/var/www/html!${APACHE_DOCUMENT_ROOT}!g' /etc/apache2/apache2.conf

# Enable rewrite module
RUN a2enmod rewrite

EXPOSE 80

CMD ["apache2-foreground"]

Code Example (Simplified docker-compose.yml):

version: "3.7"
services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "8000:80"
    volumes:
      - .:/var/www/html
    depends_on:
      - db
  db:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: your_root_password
      MYSQL_DATABASE: your_database_name
    ports:
      - "3306:3306"
    volumes:
      - db_data:/var/lib/mysql

volumes:
  db_data:

To use this, place these files in the root of your Zend Framework / Laminas project directory. Then run docker-compose up -d to build and start the containers. Your application will be accessible at http://localhost:8000.

2. Using a Pre-built Virtual Machine or Vagrant Box:

Instead of manually installing all the necessary software, you can use a pre-configured virtual machine (VM) image or a Vagrant box that includes PHP, Apache, MySQL, and other tools.

Explanation:

VMs and Vagrant provide a complete, isolated environment for your application. Several pre-built boxes or VM images are available with LAMP (Linux, Apache, MySQL, PHP) stacks already installed and configured. This significantly reduces the setup time and complexity, especially for beginners. Vagrant automates the creation and configuration of virtual machine environments, making it easy to replicate development environments.

How to Use (Vagrant Example):

Install Vagrant and VirtualBox (or another virtualization provider).
Create a Vagrantfile in your project directory.
Add the following content to the Vagrantfile (example using a LAMP stack box):

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/trusty64" # Or use another LAMP stack box
  config.vm.network "forwarded_port", guest: 80, host: 8080
  config.vm.network "private_network", ip: "192.168.33.10"
  config.vm.synced_folder ".", "/var/www/html"
  config.vm.provision "shell", inline: <<-SHELL
    sudo apt-get update
    sudo apt-get install -y apache2 php5 libapache2-mod-php5 mysql-server php5-mysql
    sudo a2enmod rewrite
    sudo service apache2 restart
  SHELL
end

Run vagrant up in your project directory. This will download the box and configure the VM.

Your Zend Framework / Laminas project files in your local directory will be synced to /var/www/html inside the VM, and you can access your application at http://localhost:8080 or http://192.168.33.10. You will likely need to adjust the Vagrantfile to reflect your specific needs, such as installing the correct PHP version and enabling the required modules. You may also need to adjust Apache configuration within the VM.
