MariaDB serves as the database management system for storing ProcessWire’s data.

sudo apt install mariadb-server mariadb-client -y
sudo systemctl start mariadb
sudo systemctl enable mariadb

Secure your MariaDB installation by running:

sudo mysql_secure_installation

Follow the prompts to set a root password and secure your database server.

PHP and Required Extensions

PHP is the scripting language that powers ProcessWire. Install PHP along with necessary extensions:

sudo apt install php libapache2-mod-php php-mysql php-xml php-mbstring php-json php-curl -y

After installation, verify PHP is correctly integrated with Apache:

sudo systemctl restart apache2

Create a PHP info file to confirm the PHP setup:

echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/info.php

Navigate to http://your-server-ip/info.php in your browser. You should see the PHP information page, indicating a successful PHP setup.

Database Configuration

Setting up a dedicated database for ProcessWire enhances security and organization.

Creating ProcessWire Database

sudo mysql -u root -p

Enter your MariaDB root password when prompted, then create the database:

CREATE DATABASE processwire_db;

Setting Up Database User

Create a new database user and grant necessary permissions:

CREATE USER 'processwire_user'@'localhost' IDENTIFIED BY 'secure_password';
GRANT ALL PRIVILEGES ON processwire_db.* TO 'processwire_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Replace ‘secure_password‘ with a strong password to ensure database security.

Configuring Permissions

Proper permissions prevent unauthorized access and modifications:

sudo chown -R www-data:www-data /var/www/html/
sudo chmod -R 755 /var/www/html/

This sets the correct ownership and permissions for the web directory, ensuring Apache can interact with the files securely.

ProcessWire Installation

Downloading ProcessWire

Obtain the latest stable version of ProcessWire from the official repository:

cd /tmp/
wget https://github.com/processwire/processwire/archive/master.zip
sudo apt install unzip -y
sudo unzip master.zip
sudo mv processwire-master /var/www/html/processwire

This sequence of commands downloads, extracts, and moves the ProcessWire files to the Apache root directory.

File System Setup

Ensure the directory structure is correct and permissions are properly set:

Directory Structure

Navigate to the ProcessWire directory:

cd /var/www/html/processwire

The directory should contain all necessary ProcessWire files and folders.

Permission Configuration

Set appropriate file permissions to maintain security:

sudo chown -R www-data:www-data /var/www/html/processwire/
sudo chmod -R 755 /var/www/html/processwire/

Apache Virtual Host Setup

Create a virtual host configuration to manage your ProcessWire site:

sudo nano /etc/apache2/sites-available/processwire.conf

Add the following configuration:

<VirtualHost *:80>
        ServerAdmin admin@yourdomain.com
        ServerName yourdomain.com
        ServerAlias www.yourdomain.com
        DocumentRoot /var/www/html/processwire

        <Directory /var/www/html/processwire>
                Options Indexes FollowSymLinks
                AllowOverride All
                Require all granted
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Enable the new site and rewrite module:

sudo a2ensite processwire.conf
sudo a2enmod rewrite
sudo systemctl restart apache2

Configuration Process

With the environment prepared and ProcessWire files in place, proceed to configure the CMS through its web installer.

Web Installer Navigation

Open your browser and navigate to http://yourdomain.com. You should be greeted by the ProcessWire installation wizard.

Database Connection Setup

Enter the database details you configured earlier:

Database Host: localhost
Database Name: processwire_db
Database User: processwire_user
Database Password: secure_password

Click on the “Continue” button to proceed.

Admin Account Creation

Create your administrative account by providing the necessary details:

Username: admin
Password: your_secure_password
Email: admin@yourdomain.com

Ensure your password is strong to maintain security.

Security Enhancements

Securing your ProcessWire installation is paramount to protect your website from potential threats.

SSL Certificate Installation

Encrypt data transmitted between your server and users by installing an SSL certificate:

sudo apt install certbot python3-certbot-apache -y
sudo certbot --apache -d yourdomain.com -d www.yourdomain.com

Follow the prompts to obtain and install the certificate. This ensures secure HTTP (HTTPS) connections.

File Permissions Hardening

Restrict file permissions further to enhance security:

sudo find /var/www/html/processwire/ -type d -exec chmod 755 {} \;
sudo find /var/www/html/processwire/ -type f -exec chmod 644 {} \;

These commands set appropriate permissions for directories and files, preventing unauthorized access.

Apache Security Configuration

Strengthen Apache’s security settings by disabling unnecessary modules and enforcing security headers:

sudo a2dismod status
sudo a2dismod autoindex

Additionally, add security headers by editing the virtual host configuration:

sudo nano /etc/apache2/sites-available/processwire.conf

Insert the following within the block:

Header always set X-Frame-Options "SAMEORIGIN"
Header always set X-Content-Type-Options "nosniff"
Header always set X-XSS-Protection "1; mode=block"

Save the file and restart Apache:

sudo systemctl restart apache2
