# Deploy and Host MariaDB on Railway

Deploy a fully configured, persistent MariaDB instance on Railway in one click. This template provisions the official `mariadb` Docker image with auto-generated credentials, persistent volume storage at `/var/lib/mysql`, and private  connection URL ready to use immediately.

## About Hosting MariaDB

MariaDB is an open-source relational database management system created by MySQL's original developers. It's a high-performance, drop-in MySQL replacement used by Wikipedia, WordPress.com, and thousands of production applications.

**Key features:**
- Full ACID compliance with InnoDB storage engine
- MySQL-compatible wire protocol — existing MySQL drivers work unchanged
- Faster query execution and replication than MySQL for most workloads
- JSON functions, virtual columns, and sequence storage engines not in MySQL
- Active open-source community with LTS releases (current: MariaDB 11.4)

## Why Deploy MariaDB on Railway

Managing MariaDB on a VPS means handling OS updates, firewall rules, `bind-address` config, and backup cron jobs yourself. Railway eliminates that:

- **Private networking** — your app connects via `MARIADB_PRIVATE_URL` without exposing port 3306 to the internet
- **Persistent volume** — data survives redeploys, mounted automatically at `/var/lib/mysql`
- **Auto-generated secrets** — root password and user password are cryptographically random on first deploy
- **TCP proxy** — public access available via `MARIADB_PUBLIC_URL` when you need it for GUI tools
- **Zero config** — no `my.cnf` editing, no `mysql_secure_installation`, no firewall rules

## Common Use Cases

- **Backend database** for Node.js, PHP, Python, or Ruby apps deployed on Railway
- **WordPress / Laravel / Drupal** data layer — all support MariaDB natively
- **Replacing a managed RDS instance** to cut costs while keeping SQL compatibility
- **Development and staging databases** isolated per Railway environment

## Dependencies for MariaDB

MariaDB is self-contained. No external services are required.

- No external message queue, cache, or object storage needed
- A Railway project (free tier works for development)

### Environment Variables Reference for MariaDB

| Variable | Description | Required |
|---|---|---|
| `MARIADB_DATABASE` | Database name created on startup | Yes |
| `MARIADB_USER` | Non-root database user | Yes |
| `MARIADB_PASSWORD` | Password for `MARIADB_USER` (auto-generated) | Yes |
| `MARIADB_ROOT_PASSWORD` | Root user password (auto-generated) | Yes |
| `MARIADB_HOST` | Private hostname (Railway internal network) | Yes |
| `MARIADB_PORT` | Database port, default `3306` | Yes |
| `MARIADB_PRIVATE_URL` | Full DSN for internal Railway service connections | Yes |
| `MARIADB_PUBLIC_URL` | Full DSN for external connections via TCP proxy | Optional |
| `MARIADB_PUBLIC_HOST` | Public TCP proxy hostname | Optional |
| `MARIADB_PUBLIC_PORT` | Public TCP proxy port | Optional |

### Deployment Dependencies

- Docker image: [`mariadb`](https://hub.docker.com/_/mariadb) (official Docker Hub image)
- Persistent volume mounted at `/var/lib/mysql`
- Railway TCP proxy enabled for public access

## Getting Started with MariaDB on Railway

After deploying, Railway injects all connection variables into your project. Connect another Railway service by referencing `$MARIADB_PRIVATE_URL` in its environment. For GUI access from your laptop, use `MARIADB_PUBLIC_URL` with [TablePlus](https://tableplus.com/), [DBeaver](https://dbeaver.io/), or MySQL Workbench.

```
# Connect from your local machine using the public URL
mysql -h $MARIADB_PUBLIC_HOST -P $MARIADB_PUBLIC_PORT \
  -u railway -p railway
```

## Self-Hosting MariaDB

To run the same setup outside Railway on any Docker host:

```
docker run -d \
  --name mariadb \
  -e MARIADB_DATABASE=railway \
  -e MARIADB_USER=railway \
  -e MARIADB_PASSWORD=yourpassword \
  -e MARIADB_ROOT_PASSWORD=yourrootpassword \
  -v mariadb-data:/var/lib/mysql \
  -p 3306:3306 \
  mariadb:latest
```

This mirrors exactly what the Railway template runs. For production VPS deployments, also configure UFW (`ufw allow 3306/tcp` only from trusted IPs) and set `bind-address` in `/etc/mysql/mariadb.conf.d/50-server.cnf`.

## MariaDB vs MySQL

| Feature | MariaDB | MySQL |
|---|---|---|
| License | GPL (fully open source) | GPL + commercial Oracle tiers |
| Query speed | Faster for most read workloads | Slower in benchmarks post-8.0 |
| JSON support | Full JSON functions + LONGTEXT alias | Native JSON type |
| Drop-in compatibility | High (wire-compatible) | — |
| Extra engines | Aria, ColumnStore, Spider | Limited |

**Choose MariaDB** if you want a fully open-source, community-driven database with no Oracle dependency. **Choose MySQL** if your stack requires MySQL 8.0-specific features or enterprise Oracle support contracts.

## How Much Does MariaDB Cost?

MariaDB Community Server is **free and open source** under the GPL license. You pay only for the infrastructure running it. On Railway, that's your project's compute and volume usage — starting from the Hobby plan at $5/month. MariaDB's commercial offering (MariaDB Enterprise) adds enterprise support and MaxScale proxy, but is unnecessary for most self-hosted deployments.

## Troubleshooting

**Can't connect externally?** 
Use `MARIADB_PUBLIC_URL` — the private URL only works within Railway's internal network.

**"Access denied" errors?** 
The template creates user `railway` with access to database `railway` only. Use root credentials for admin tasks.

**Data lost after redeploy?** 
Ensure the volume is attached. Check Railway's volume settings — the mount path must be `/var/lib/mysql`.

**Service won't start?** 
Check Railway logs. Common cause: volume mount permission issue or a corrupted `ibdata1` from a forced container kill.

## FAQ

**Is MariaDB a drop-in replacement for MySQL?**
Yes. It uses the same wire protocol, so MySQL drivers (e.g., `mysql2` for Node.js, `PyMySQL`, `PDO_mysql`) connect without changes.

**Can I connect mariadb from a local GUI tool?**
Yes — use `MARIADB_PUBLIC_HOST` and `MARIADB_PUBLIC_PORT` with any MySQL-compatible client like TablePlus or DBeaver.

**How do I back up my data in mariadb?**
Run `mysqldump` against the public endpoint, or use Railway's volume snapshot feature. For automated backups, add a cron service to your Railway project.

**What MariaDB version is deployed?**
The template uses the `mariadb` Docker image tag, which pulls the latest stable release. Pin to a specific version (e.g., `mariadb:11.4`) in Railway's service settings for production stability.
