InfluxDB not starting: 8086 bind address already in use-CodePudding

I have an InfluxDB Version 1.8.9, but I can't start it. In this example I'm logged in as a root.

netstat -lptn

gives me a range of services, none of them seem to listen to 8086. (there are other services running like grafana or MySQL, which seem to work fine)

To further confirm nothing is on 8086,I listened to that related Issue run: open server: open service: listen tcp :8086: bind: address already in use on starting influxdb and run

netstat -a | grep 8086

which results in no results.

My config file on /etc/influxdb/influxdb.conf looks like this:

reporting-disabled = false
bind-address = "127.0.0.1:8086"

So i tried to start my database:

service influxdb start

Which gives me

ob for influxdb.service failed because a timeout was exceeded. See "systemctl status influxdb.service" and "journalctl -xe" for details.

result of systemctl status influxdb.service

I can't really understand where I did something wrong, since I configured :8086 in the config file. Can you help me?

CodePudding user response：

It appears to be a typo in the configuration file. As stated in the documentation, the configuration file should hold http-bind-address instead of bind-address. As well as a locked port by the first configuration.

The first few lines of the file /etc/influxdb/influxdb.conf should look like so:

reporting-disabled = false
http-bind-address = "127.0.0.1:8086"

A suggested approach would be to:

bind-address to http-bind-address
Changing the port from default 8086 to a known free port
(Optional) Back to the default port.
