Missing RuntimeDirectory in Systemd service file (Ubuntu 24.04 Server)

[melroy89]

Steps to reproduce:

1. Running InfluxDB v1.11.8
2. Edit the influxdb.conf and enable unix socket:

   unix-socket-enabled = true
   bind-socket = "/var/run/influxdb/influxdb.sock"
   

3. Using the default /usr/lib/systemd/system/influxdb.service file, provided by you.
4. Failing to start InfluxDB!

Expected behavior:

Influxdb starting without errors and write the socket file.

Actual behavior:

Ubuntu Server 24.04 prohibits the writing of the socket file (/var/run/influxdb/influxdb.sock) to disk, because you didn't allow the systemd service file write access to the /var/run/influxdb directory..... See fix below!

InfluxDB unable to start in Ubuntu 24.04, because the service file is unable to write the socket file to /var/run/influxdb directory.

Fix:

The fix is easy, please extend your official influxdb.service in your Ubuntu packages with the following:

[Service]
....
RuntimeDirectory=influxdb
RuntimeDirectoryMode=0755

Config:
Copy any non-default config values here or attach the full config as a gist or file.

unix-socket-enabled = true
bind-socket = "/var/run/influxdb/influxdb.sock"
