Influxdb: Changing port not working

[ericjmiller]

I'm trying to change the port used by Influx's HTTP (from 8086 to 80) and Admin. I've been revising and experimenting with the config file to do this. Once I finished revising the config file, I start influx like so:

sudo /opt/influxdb/influxd -config /home/ec2-user/influxdb/influx.conf

If it's a port I've tried in the past, I'll recieve the following message:

_using configuration at: /home/ec2-user/influxdb/influx.conf
run: open server: listen: listen tcp :8088: bind: address already in use_

If I run the config file with a new port, I get something like the following:

_using configuration at: /home/ec2-user/influxdb/influx.conf

I've tried many different ports for HTTP functionality, and only 8086 (the default works). Can someone outline for me the steps needed to change the port for HTTP / Admin? Am I doing something wrong?

[ericjmiller]

My netstat -lntp command shows that only ports 8083, 8086, and 8088 are being used, even after running influx with the config file defining other ports. I'm doing something wrong here, I presume.

[ericjmiller]

Solved the problem: I had to manually kill all previously existing influx processes. Then I could run influx command successfully with -config flag.

ps -xa | grep influx
kill
