[Solved] Failed to auto start signalk-server on boot

[volksbar]

Hello,

I installed signalk via the command line instruction on signalk's github repo. However, I need to manually start "signalk-server" from the terminal in order to access the localhost signalk interface.

I would like to auto start the signalk-server on boot. I tried:

sudo systemctl enable signalk.service
sudo systemctl enable signalk.socket


But it did not auto start and the error is:

● signalk.service
    Loaded: loaded (/etc/systemd/system/signalk.service; enabled; vendor preset: enabled)
    Active: failed (Result: exit-code) since Fri 2023-11-24 00:40:02 CET; 5min ago
TriggeredBy: ● signalk.socket
    Process: 808 ExecStart=/home/pi/.signalk/signalk-server (code=exited, status=127)

Nov 24 00:40:02 openplotter systemd[1]: Failed to start signalk.service.

When I run signal-server-setup, I got:
"pi@openplotter:~ $ sudo signalk-server-setup
/usr/bin/env: ‘node’: No such file or directory"

But the node was installed:
"
pi@openplotter:~ $ node -v
v21.2.0
pi@openplotter:~ $ which node
/home/pi/.config/nvm/versions/node/v21.2.0/bin/node
"

Any ideas? Any hints to debug is helpful. Many thanks!

hi volkbar

normaly it is enabled via servce automatically

try "systemctl is-enabled signalk"
if not enabled:
"sudo systemctl enable signalk"

post your status here: "sudo service signalk status"

Hello Holger,

Thanks for your reply. 

It seems to be enabled.
"
pi@openplotter:~ $ systemctl is-enabled signalk
enabled
"
But my signalk status is:

I solved it by:
1. which node
-> It returned "/home/pi/.config/nvm/versions/node/v21.2.0/bin/node"
2. sudo ln -s /PATH/RETURNED/IN/STEP/1 /usr/bin/node

I installed node via nvm, while signalk service was not aware of such a path.

@Holger: Thanks again for thinking along!

okay - fine you got it resolved.
sometimes linux needs thinking around, but mostly it´s a piece of logical.
