I can not figure out how to stop a running geth node without killing the process. I tried to lookup geth help but there is no mention of stopping, halting or any shutdown command.
How to shutdown geth cleanly?
I'm running it as a daemon, CTRL+C is no option.
Because you ran geth as a daemon you can either:
killall -HUP geth
in one line, or get the pid with:
ps ax | grep geth
and kill it with kill
kill -HUP <pid>
-HUP is the sighup signal, is optional but is more gentle than the normal TERM signal.
ps and piping it to grep, you can use pgrep geth. One-liner: kill -HUP $(pgrep geth).

use Ctrl c or
kill -INT <pid>
if you started geth with console, you exit with Ctrl D or
> exit
Ctrl+c than opening up a new terminal tab to kill this.

Geth can be stopped by sending it a keyboard interrupt with Ctrl + c. You should see output similar to the following.
I0127 09:46:49.971487 62813 blockchain.go:1230] imported 1 block(s) (0 queued 0 ignored) including 0 txs in 2.836192ms. #913170 [2eb50f50 / 2eb50f50]

In the event that go-ethereum receives multiple interrupts before shutting down cleanly, you should see something like this.
I0127 09:50:47.173412 63063 cmd.go:129] Already shutting down, please be patient.
I0127 09:50:47.173433 63063 cmd.go:130] Interrupt 9 more times to induce panic.
In this case if you continue to hit Ctrl + c to force the process to quit you may corrupt the underlying databases that go-ethereum maintains.
If the process is running as a daemon, then you can kill it with kill -INT <pid> where <pid is the process id for the running geth process.
One way to find the process id is with ps aux | grep geth.
$ ps aux | grep geth
user 63353 91.2 0.2 573457444 29844 s019 R+ 10:15AM 0:01.97 geth --rpc
user 63355 0.0 0.0 2434836 780 s021 S+ 10:15AM 0:00.00 grep geth
Here the pid that should be killed is 63353.
Simply use
pkill -INT geth
which will reuslt in the same as pressing CTRL-C in geth console:
...

Ctrl D and then exit worked for me
