## Common questions

### Should the CouchDB service be started as root in a self-hosted setup?

No, run it from a dedicated couchdb account rather than root. This avoids permission problems with CouchDB's data files and settings.

### Which port must be reachable for other machines to use the default CouchDB web/API?

Open port 5984 on your firewall. It is the default web/API port, and blocking it prevents client or browser requests from connecting.

### Can a single-node CouchDB deployment later be turned into a cluster?

Yes. CouchDB can start as a single node, and more demanding projects can seamlessly upgrade to a cluster.

### Is a self-hosted CouchDB instance the preferred backend for the Self-hosted LiveSync plugin?

Yes. The plugin supports various backends, but a self-hosted CouchDB instance is the primary recommended architecture.

### If Obsidian LiveSync says CouchDB settings are wrong or suboptimal, can it correct them?

Yes. Obsidian LiveSync can provide buttons to fix the individual config options.
