## Common questions

### Do I need to create an initial user, organization, and bucket in InfluxDB 2?

Yes. On first run, create the initial admin user, organization, and bucket so the instance can accept logins and writes. If skipped, sign-in or writes may fail.

### Which port should I expose for the InfluxDB API and web UI?

Expose the default port 8086. If you map a different port, browsers and clients may not be able to reach InfluxDB.

### How should I tell a monitor that InfluxDB is ready?

Point the health check at GET /ready. This avoids marking the app healthy too early or connecting while it is still booting.

### Does InfluxDB 3 Core need a cloud object store?

No. It can persist Parquet files to object storage such as S3, Azure, or GCP, or to local disk with no dependencies.

### Where are InfluxDB v1 logs on a Linux host?

On System V systems they are under /var/log/influxdb/. On systemd systems, use journalctl -u influxdb to view them.

### Can existing InfluxDB 1.x or 2.x writers send data to InfluxDB 3 Core?

Yes. InfluxDB 3 Core is compatible with InfluxDB 1.x and 2.x write APIs and the InfluxDB 1.x InfluxQL query API.
