Verified Work
System Admin & Hosting Projects
1. Moodle LMS Deployment & Database Integration
Deployed a full-featured Moodle Learning Management System environment on a Linux stack. Managed complex directory permissions (`moodledata`), database schema initialization, PHP dependency extensions, and automated CRON tasks for student management.
Architecture Highlights:
- Configured MariaDB database user permissions & utf8mb4 collation
- Set up dedicated Moodledata directory outside web root with strict 777/755 rules
- Optimized PHP limits (`memory_limit = 512M`, `max_execution_time = 300`)
2. Deploy 2 Websites on Apache Server
Configured Apache Virtual Hosts to simultaneously serve two distinct domain sites from a single Ubuntu host. Implemented isolated document roots (`/var/www/site1` & `/var/www/site2`), distinct log monitoring, and DNS domain routing.
Architecture Highlights:
- Dual VirtualHost `.conf` files inside `/etc/apache2/sites-available/`
- Custom error logging per site (`site1_error.log`, `site2_error.log`)
- Enabled `a2ensite` and graceful systemctl web service reloads
3. Configure Apache Web Server on Ubuntu
Full installation, initialization, and security hardening of Apache HTTP service on Ubuntu Linux. Includes custom directory indexing, UFW firewall rule setup for web traffic (Port 80/443), and module optimization (`mod_rewrite`, `mod_ssl`).
Architecture Highlights:
- Configured `UFW allow 'Apache Full'` security rules
- Directory permission assignment (`www-data` user ownership)
- Disabled server signature and directory listing for security
4. Basic Database Setup & Administration
Designed relational database structures, configured MySQL/MariaDB server parameters, created secure database accounts with tailored privilege grants, and established automated SQL backup scripts for routine server recovery.
Architecture Highlights:
- Ran `mysql_secure_installation` to root-lock default configurations
- Created custom schemas with user roles (`GRANT ALL ON db.* TO 'user'@'localhost'`)
- Configured automated `mysqldump` CRON schedules for daily backups
