Extract the files from the package: cd /var/www/html sudo unzip modx-install.zip
  7. Set up Database: Create a new MySQL database and user for MODX: sudo mysql: Connect to the MySQL server. Create a new database (replace "modxDB" with your preferred name): CREATE DATABASE modxDB; Create a new user and grant privileges: GRANT ALL PRIVILEGES ON modxDB.* TO 'modxuser'@'localhost' IDENTIFIED BY 'your_password'; FLUSH PRIVILEGES; Replace "modxuser" and "your_password" with your preferred username and password. Exit MySQL: exit
  8. Run MODX Installer: Using a web browser, visit your Droplet's IP address or domain name to start the MODX installer. Follow the on-screen instructions and provide the MySQL database details (name, username, password) when prompted.
  9. Complete the Installation: After the installation, MODX will generate a config.core.php file. Move it to the correct directory: sudo mv /var/www/html/config.core.php.core /var/www/html/core/config/config.core.php
  10. Clean Up: To enhance security, remove the MODX installation package and rename the MODX setup directory: sudo rm /var/www/html/modx-install.zip sudo mv /var/www/html/setup /var/www/html/setup_old


That's it! You have successfully installed MODX on DigitalOcean. You can now access your MODX website by visiting your Droplet's IP address or domain name in a web browser.

How to configure SSL/TLS certificates for a MODX site on DigitalOcean?

To configure SSL/TLS certificates for a MODX site on DigitalOcean, you can follow these steps:

  1. Generate a SSL/TLS certificate: Use a certificate authority (CA) or a free service like Let's Encrypt to generate a certificate. You can use Certbot, a command-line tool, to generate and manage the certificates.
  2. Set up a web server: Install and configure Nginx or Apache as your web server. Enable SSL/TLS support in the server configuration.
  3. Update your site configuration in MODX: Access the MODX Manager and navigate to the "Settings" menu. Go to the "Configuration" section and select "Site". Update the "base_url" value to use the HTTPS protocol (i.e., https://yourdomain.com).
  4. Update your site's .htaccess file: If you're using Apache, update the .htaccess file in the root of your MODX installation. Add the following lines to redirect all HTTP traffic to HTTPS: RewriteCond %{HTTP:X-Forwarded-Proto} !https RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
  5. Restart your web server: Restart Nginx or Apache for the changes to take effect.
  6. Test your SSL/TLS configuration: Access your site using the HTTPS protocol (i.e., https://yourdomain.com). Verify that the SSL/TLS certificate is valid and properly installed.


By following these steps, you can successfully configure SSL/TLS certificates for your MODX site on DigitalOcean.


How to scale a MODX site hosted on DigitalOcean?

Scaling a MODX site hosted on DigitalOcean involves several steps:

  1. Evaluate server performance: Before scaling, assess the current server's performance to determine if it is the best fit for your needs. Monitor the server's CPU, memory, and disk usage to identify any bottlenecks or limitations.
  2. Optimize MODX: Review your MODX site to ensure it is optimized for performance. This may involve disabling unnecessary modules, optimizing database queries, caching content, and minimizing external requests.
  3. Load balancing: Implement load balancing to distribute traffic across multiple servers. DigitalOcean offers load balancers that can automatically route incoming traffic to different servers based on customizable rules. Set up load balancing to ensure high availability and distribute the load evenly.
  4. Server replication: Replicate the server configuration by creating multiple instances of the server. This helps distribute the load and provides redundancy in case one server fails. You can use DigitalOcean's droplet snapshots to clone your server setup.
  5. Database scaling: If your MODX site heavily relies on database operations, consider scaling the database separately. DigitalOcean offers managed databases like MySQL and PostgreSQL, which can be easily scaled up or down depending on your needs.
  6. Content Delivery Network (CDN): Implement a CDN to improve site performance and reduce server load. A CDN caches your static site assets in multiple locations, reducing the time it takes to deliver content to users and offloading some of the traffic from your server.
  7. Monitoring and auto-scaling: Set up monitoring tools (such as New Relic or server monitoring offered by DigitalOcean) to track server performance, availability, and user experience. Use this data to determine when to scale your infrastructure automatically. DigitalOcean also provides options for auto-scaling based on predefined rules.
  8. Continuous integration and deployment: Implement a CI/CD pipeline to automate the deployment process and ensure smooth scaling. Platforms like GitLab or Jenkins can help you achieve this, allowing for easy and controlled deployments of your MODX updates.


By following these steps, you can scale your MODX site hosted on DigitalOcean to handle increased traffic and improve performance.
