How much RAM does Nexus Repository need?

Plan on 4 GB for typical use; add headroom if you expect many concurrent users.

Can I run other things on the same VPS?

Yes — size the plan so Nexus Repository plus your other workloads fit in RAM with room to spare.

Development

A universal artefact repository manager.

Store and proxy artefacts for many ecosystems — npm, Maven, PyPI, Docker, apt and more — from one server.

For polyglot teams, one proxy/cache for every package format keeps builds fast, reproducible and independent of public registries.

1
Provision a VPS
Pick a Debian/Ubuntu template and get root SSH in about a minute.
2
Install the runtime
Install Java + blob store.
3
Deploy the application
Net what you need from the project’s official source and run it.
4
Put it behind TLS
Reverse-proxy with Nginx and issue a Let’s Encrypt certificate.
5
Add it to your backups
Include the data directory and database in your backup routine before you rely on it.

Give Nexus Repository its own database user with rights only on its own schema.
Reverse-proxy Nexus Repository and terminate TLS at the proxy so certificates are managed in one place.
Take a VPS snapshot before major upgrades so you can roll back cleanly.
Keep Nexus Repository patched — most self-hosting incidents are unpatched software.
