influxdb installion and getting 404, couldnt create 2nd DB

Hi,

I have installed influxdb as non-root user.
integated with Grafana with port 8086, but for same url "postman" returns 404, even "http://xxx:8086/login" returns 404,
on linux host "$influx" returns command not found.
Any suggestions or workarounds please?

Start by separating the reported InfluxDB installation, HTTP 404, second-database, and shell-command problems; the issue names no files, tests, or entry points. Reproduce the requests and command behavior in the stated Linux, Grafana, and Postman setup, then define completion only after the specific failing behavior and expected result are clarified.
