This project documents the manual deployment of the VProfile multi-tier application in a local virtualized environment. Five VMs are provisioned to isolate each service tier, highlighting service dependencies, configuration flow, and end-to-end deployment.
The system follows a classic multi-tier architecture where each service is isolated for scalability and security.
- Virtualization & Orchestration: Oracle VM VirtualBox and Vagrant.
- Web Tier: Nginx acting as a web server and reverse proxy.
- Application Tier: Apache Tomcat serving the Java application.
- Messaging/Brokerage: RabbitMQ for queuing and broker services.
- Caching Layer: Memcached for database caching.
- Database Tier: MySQL/MariaDB for relational data storage.
The deployment order follows service dependencies so that backend services are ready before the application tier connects.
Configured the vagrant-hostmanager plugin to enable VM-to-VM name resolution via hostnames instead of static IPs.
Initialized the accounts database, verified schema load, and ensured port 3306 access.
Configured Memcached to listen on port 11211 and validated the service startup.
Provisioned RabbitMQ with a dedicated administrative user and validated service status.
Installed Java 17 and Tomcat 10 on app01 and validated the Tomcat service.
Built the application from source using Maven and deployed the generated .war into Tomcat.
Configured Nginx on web01 as a reverse proxy and verified the service status.
- Linux Administration: Package management, service control, and permissions.
- Network Security: Host-based firewall rules to secure service ports.
- Infrastructure as Code (Intro): Reproducible VM provisioning with Vagrant.
