Redmine runs reliably on different stack combinations, but the right choice depends on your team skills, maintenance model, and expected workload.
| Aspect | Apache + Passenger | Nginx + Passenger |
|---|---|---|
| Learning curve | Often simpler for teams used to classic web hosting. | Preferred by teams already operating Nginx in production. |
| Configuration style | VirtualHost-based, straightforward for small environments. | Server block model, more modular for larger deployments. |
| Static content handling | Good enough for most Redmine workloads. | Strong static file efficiency under heavier traffic. |
| Default choice | Great baseline if you prioritize simplicity. | Great baseline if you prioritize edge routing and flexibility. |
| Aspect | MariaDB | PostgreSQL |
|---|---|---|
| Operational familiarity | Common choice in LAMP-style environments. | Common choice in modern engineering platforms. |
| Strictness and consistency | Flexible and fast to get started. | Strong defaults and robust transactional behavior. |
| Upgrade workflows | Simple for basic installations. | Predictable for teams with mature DB operations. |
| Default choice | Good when existing ops already uses MariaDB/MySQL. | Good when your team already runs PostgreSQL for apps. |
Standardize on one baseline first. Supporting many combinations too early increases support and maintenance overhead.
