Systemd / init.d autostart script

[mzuenni]

Hey another enhancement would be to automatically install and give the user the ability to activate a Systemd or/and init.d script. In my time i want to start it at boot time (like an apachi server) i already tried to write an Systemd script my self but nothing happens...

[Unit]
Description = airdcppd daemon
After = NetworkManager-wait-online.service network.target network-online.target
Wants = display-manager.service NetworkManager-wait-online.service network-online.target

[Service]
Type = simple
PIDFile = /var/run/airdcppd.pid
ExecStart = /usr/local/bin/airdcppd -d

[Install]
WantedBy = multi-user.target

i also tried the -c option because i dont know as which user the program start/where the configuration needs to be but even then nothing happens... (if i use the start command manually it works)

This is what I did, maybe it will help.

The pid file is also located inside the config directory.

This works for me:

[Unit]
Description=A peer-to-peer file sharing client with web user interface
After=network.target

[Service]
User=airdcpp
Group=media
ExecStart=/usr/local/bin/airdcppd -c=/var/lib/airdcpp

[Install]
WantedBy=multi-user.target

I'm running AirDC++ under its own user (airdcpp), so modify accordingly to suit your setup. Because the daemon doesn't fork or do anything weird, systemd will keep track of the process automatically.

[mzuenni]

hello i also tried your script but still it does nothing... my script currently looks like this:

[Unit]
Description=airdcppd daemon
After=network.target

[Service]
User=zuenni
Group=users
ExecStart=/usr/local/bin/airdcppd -c="/media/data/airdcpp/config" -web-resources="/media/data/airdcpp/webUI"

[Install]
WantedBy=multi-user.target

and the file is located at "/etc/systemd/system/airdcppd.service" then i run :

sudo systemctl enable airdcppd.service
sudo systemctl start airdcppd.service

to test it but the program doesnt start but i dont get any feedback.... (if i manually run the ExecStart line manually everything works like expected)

is there anything i should do? (its the first time i an using systemd)

[maksis]

I tried that script and it works fine for me. Are you still having problems?

[mzuenni]

yes it works now for me too. i dont know what caused the problem for me ^^

[KipourosV]

Normally I run airdcppd with the -d switch and nothing else. How would I write the ExecStart= ??

Do I keep the -d switch?

[maksis]

Based on the previous comments, I wouldn't keep that switch

[KipourosV]

There is a guide on creating the system scripts for deluge on their site. They also use the -d switch for deluge and have the switch in their scipt example...

[maksis]

It should be easy to test whether the option works. Have you tried to run the script? It will spam the typical console messages to syslog when not using the -d option but there are other ways to disable such output if needed.

[maksis]

You may get strange errors when the application is launched on system startup before network connectivity is available.

According to this article, After=network.target is almost meaningless.

I replaced After=network.target with After=network-online.target and based on a few test reboots, it seemed to have fixed the issue for me.

Hi i need abit of help i cant get this to autostart. This works great

sudo systemctl enable airdcppd.service sudo systemctl start airdcppd.service

But it wont start even if i change to After=network-online.target

[maksis]

Could you paste the full script that you are using?

[ghost]

This is what i use in /etc/systemd/system/airdcppd.service

[Unit] Description=A peer-to-peer file sharing client with web user interface After=network-online.target

[Service] User=airdcpp Group=shareDC ExecStart=/usr/local/bin/airdcppd

[Install] WantedBy=multi-user.target

Im new at linux so maybe something basic i missed?

[maksis]

Can you find anything useful from /var/log/syslog?

i got this that where red but dont think it have something to whit it

Apr 17 15:36:05 share airdcppd[1121]: Failed to create PID file /home/airdcpp/.airdc++/airdcppd.pid$

That very much explains it. You should check the permissions of the directory /home/airdcpp/.airdc++/ and its content (is the directory owned by a different user?)

[ghost]

hmm det owner is airdcpp but should it be that i ecryptfs the home dir :P and the grp is airdcpp and shareDC but the user airdcpp is member in both

[maksis]

Are you able to try running the app as the other user without using systemd to see if it works?

[ghost]

yep systemctl start, stop and status works thats why i dont get it. Dont have other path to config. Been looking for it in the airdc++ folder and web.

[maksis]

yep systemctl start, stop and status works thats why i dont get it.

systemctl won't detect such permission issues. What's the output of ls -la /home/airdcpp/.airdc++/?

[maksis]

Can run the app with the wanted user and group from terminal by using the runuser command?

[maksis]

Apr 17 15:36:05 share airdcppd[1121]: Failed to create PID file /home/airdcpp/.airdc++/airdcppd.pid$

There's also more text on the right, that will show the exact error message.

[ghost]

Apr 17 16:06:33 share airdcppd[1107]: Failed to create PID file /home/airdcpp/.airdc++/airdcppd.pid: No such file or directory

but airdcpp is a root user

dont get the runuser command

airdcpp@share:/var/log$ runuser -l airdcpp -c airdcpp runuser: may not be used by non-root users

[ghost]

Or is it bad ide too have it as a root user?

[maksis]

It means that you are expected to run the command as root

[ghost]

Hi i got it to work. I think the problem was that i encrypted the home dir. :P Thx for the help

[Kcchouette]

I'm doing a autostart using screen su --command="screen -dmS ${user}-airdcpp airdcpp" "${user}" and a init.d script I've put in /etc/init.d/

[KipourosV]

[Unit] Description=airdcppd daemon After=network-online.target

[Service] Type=simple User=airdcppd Group=media UMask=007 PIDFile = /root/.airdc++/airdcppd.pid ExecStart = /usr/local/bin/airdcppd

Restart=on-failure

TimeoutStopSec=300

[Install] WantedBy=multi-user.target

This works for me.

FYI: The umask is the mask for permissions on files created by airdcpp (new downloads) 007 means the created files get 770.
