Self-hosting phpMyAdmin the easy way
Yulei ChenphpMyAdmin is one of the most popular web-based tools for managing MySQL and MariaDB databases. It gives you a clean UI for browsing tables, running SQL queries, importing/exporting data, and managing users - all from your browser. It's free, open-source, and has been around for over 25 years.
Sliplane is a managed container platform that makes self-hosting painless. With one-click deployment, you can get phpMyAdmin up and running in minutes - no server setup, no reverse proxy config, no infrastructure to maintain.
Prerequisites
Before deploying, ensure you have a Sliplane account (free trial available).
Quick start
Sliplane provides one-click deployment with presets.
Deploy phpMyAdmin >- Click the deploy button above
- Select a project
- Select a server (If you just signed up you get a 48-hour free trial server)
- Click Deploy!
About the preset
The one-click deploy above uses Sliplane's phpMyAdmin preset. Here's what it includes:
- LinuxServer image (
lscr.io/linuxserver/phpmyadmin) for a well-maintained, regularly updated base - Pinned to version 5.2.3 for stability
- Persistent storage mounted to
/configfor your phpMyAdmin configuration - PMA_ARBITRARY enabled so you can connect to any MySQL or MariaDB server
- PMA_ABSOLUTE_URI auto-configured to your Sliplane domain for correct URL handling
Next steps
Once phpMyAdmin is running, open the domain Sliplane assigned (e.g. phpmyadmin-xxxx.sliplane.app). You'll see the phpMyAdmin login screen.
Connecting to a database
Since PMA_ARBITRARY is enabled, the login page shows a Server field where you enter the hostname of your MySQL or MariaDB instance. If your database runs on the same Sliplane server, use its internal service name (e.g. mysql.internal or mariadb.internal). Then enter your database username and password.
Environment variables
You can customize the setup through environment variables in your service settings:
| Variable | Default | Description |
|---|---|---|
PMA_ARBITRARY | 1 | Set to 1 to allow connecting to any server, or 0 to restrict |
PMA_ABSOLUTE_URI | https://$SLIPLANE_DOMAIN | The full URL where phpMyAdmin is accessible |
PMA_HOST | (not set) | Set this to lock phpMyAdmin to a specific database host |
PMA_PORT | (not set) | Custom port for the database connection (default: 3306) |
TZ | Europe/Berlin | Timezone for the container |
Logging
phpMyAdmin logs go to STDOUT by default, which works well with Sliplane's built-in log viewer. For tips on working with container logs, check out our guide on how to use Docker logs.
Cost comparison
You can also self-host phpMyAdmin with other cloud providers. Here is a pricing comparison for the most common ones:
| Provider | vCPU | RAM | Disk | Monthly Cost | Note |
|---|---|---|---|---|---|
| Sliplane | 2 | 2 GB | 50 GB | €22.80 | Flat rate, free egress, SSL included |
| Fly.io | 2 | 2 GB | 40 GB | ~$17.83 | Disk and bandwidth billed separately |
| Render | 1 | 2 GB | 40 GB | ~$35 | 5 GB bandwidth included on Hobby; disk billed separately |
| Railway | 2 | 2 GB | 40 GB | Up to ~$66 | Usage-based; Pro required for a 40 GB volume |

Prices checked July 19, 2026. Assuming an always-on instance running 730 hrs/month, Germany/Amsterdam where regional pricing applies, excluding VAT and egress.
- Sliplane: Base server with 2 vCPU, 2 GB RAM and 20 GB storage = €17.80/month; the 50 GB storage tier adds €5 -> €22.80/month. Unlimited services, free egress and SSL are included.
- Fly.io: in Amsterdam,
shared-cpu-2xwith 2 GB RAM = $11.83/month + 40 GB volume × $0.15/GB = $6 -> ~$17.83/month. Egress is billed separately at $0.02/GB in Europe. - Render: closest match is Standard ($25, 1 vCPU / 2 GB) plus 40 GB disk × $0.25/GB = $10 -> ~$35/month. A Hobby workspace includes 5 GB bandwidth, then charges $0.15/GB. Stepping up to Pro compute (2 vCPU / 4 GB) costs $85/month plus disk.
- Railway (Pro plan): at full resource usage: CPU 2 × $20/vCPU/month = $40; RAM 2 × $10/GB/month = $20; volume 40 × $0.15/GB/month = $6 -> up to ~$66/month. Actual CPU and RAM charges depend on usage. A 40 GB volume requires Pro; its $20/month subscription is a minimum commitment that counts toward usage, not an additional charge. Egress is $0.05/GB.

FAQ
Can I use phpMyAdmin to manage remote databases?
Yes. With PMA_ARBITRARY=1 (enabled by default in the preset), you can connect to any MySQL or MariaDB server by entering its hostname on the login screen. This works for databases on the same Sliplane server, other Sliplane services, or external database hosts.
How do I lock phpMyAdmin to a specific database?
Set the PMA_HOST environment variable to your database server's hostname (e.g. mysql.internal) and set PMA_ARBITRARY to 0. This removes the server field from the login page and always connects to the specified host.
How do I update phpMyAdmin?
Change the image tag in your service settings to the newer version and redeploy. Check Docker Hub for the latest stable version. Your configuration in /config is persisted, so updates are seamless.
Are there alternatives to phpMyAdmin?
Yes. Adminer is a lightweight single-file alternative. DBeaver is a desktop app that supports many database types. For a web-based option that works with more than just MySQL, check out NocoDB which turns your database into a spreadsheet-like interface, or Drizzle Gateway for a modern database GUI.
Is phpMyAdmin safe to expose to the internet?
phpMyAdmin itself is safe as long as your database credentials are strong. The preset runs behind Sliplane's SSL-enabled reverse proxy, so traffic is encrypted. For extra security, you can restrict access using Sliplane's allow-list feature to limit which IP addresses can reach your instance.
