I have a cpp application which broadcasts an object and its methods on the dbus. I try to run this program at startup with the following service file:
[Unit]
Description=Running dbus program
After=network.target
[Service]
Type=simple
ExecStart=/home/my_name/Documents/dbus/build/my_app
StandardOutput=console+journal
StandardError=console+journal
[Install]
WantedBy=multi-user.target
After reloading:
systemctl daemon-reload
and running it:
sudo systemctl start my_service.service
I got no error in the journal, but I cant see anything on the dbus (running d-feet, and browsing for my object, I cant find anything)
Running the exact same ExecStart:
/home/my_name/Documents/dbus/build/my_app
in the console works fine.
What am I missing? Thanks!
As you want your service to run on the session bus you will need to use:
sudo systemctl --user start my_service.service
Putting the file into /etc/systemd/user/ location will make it available to all users still.

On a Virtual Maching running on Centos7, using root privileges, I want to create a service to launch a Python (Python 3.9) webservice and restart it every hour.
Here's what i did:
creating a directory /etc/systemd/system/dlweb_doc_webservice.service.d
creating a file dlweb_db_generate_report.service like this
[Unit]
Description=dlweb_db_generate_report_webservice
After=network-online.target
Wants=network-online.target systemd-networkd-wait-online.service
[Service]
Type = simple
ExecStart=/usr/local/bin/python3.9 /opt/scripts/dlweb_db_generate_report_webservice/dlweb_db_generate_report.py
Restart=on-failure
RestartSec=5s
StartLimitIntervalSec=3600
StartLimitBurst=5
[Install]
WantedBy=multi-user.target
running systemctl daemon-reload
running systemctl --type=service --all doesn't display my service
and
running systemctl enable dlweb_db_generate_report_webservice returned a Failed to execute operation: No such file or directory
What did i miss or do wrong?
I just downloaded jbpm server from JBPM.
it starts by running "jbpm-server/bin/standalone.sh" this. But i want to start jbpm as ubuntu's service like---> systemctl start jbpm.
can anyone provide me details to create startup script for this.
You should create a file in your systemd directory, for example /etc/systemd/system/change_me.service and fill it with a basic setup like:
[Unit]
Description=Your service's description
[Service]
ExecStart=/path/to/executable.sh
[Install]
WantedBy=multi-user.target
Then you should reload your systemd configuration in order to update it with the new service via
sudo systemctl daemon-reload
And then start it
sudo systemctl start change_me
If you want a more granular control over your systemd's service file you should read the man page via:
man systemd.service
I made this service:
#!/bin/bash
node ../../home/NodeServer/server.js
All it should do is start the server on bootup, so i wanted to do
sudo systemctl enable startServer.service
But I got this error:
startServer.sh.service is not a native service, redirecting to systemd-sysv-insall.
Executing: /lib/systemd/systemd-sysv-install enable startServer.sh
update-rc.d: error: startServer.sh Default-Start contains no runlevels, aborting.
When i try to do
sudo systemctl start startServer.service
it works like intended.
I had the same problem. I solve it typing again the file because it seems that there was a strange character that was broken the parser. Hope this helps!
You want to execute a script, which is not the same as a service.
You can make a file called startServer.service and write the following into it:
[Unit]
Description=Start server that does a thing
[Service]
ExecStart=node /home/NodeServer/server.js
If you want to enable the service, do the following:
sudo ln -s /home/NodeServer/startServer.service /etc/systemd/system/
and now you should be able to start the service.
I have a DO droplet running Ubuntu 16.04.1x64 and I'm trying to run IPFS as a systemd service. I've gone ahead and created a user "connor" and installed IPFS following the instructions here. I'm storing the service as "ipfs.service" in ~/.config/systemd/user/ipfs.service which looks like this:
[Unit]
Description=IPFS Daemon
[Service]
Type=simple
ExecStart=/usr/local/bin/ipfs daemon
ExecStop=/usr/bin/pkill ipfs
Restart=always
User=Connor
[Install]
WantedBy=default.target
What's odd is that if I run systemctl --user start ipfs it starts up just fine. However, running systemctl --user daemon-reload and then
systemctl --user enable ipfs I get the error:
Failed to execute operation: No such file or directory
However, if I run systemctl enable /home/connor/.config/systemd/user/ipfs.service -f it runs just fine. I can reboot and run IPFS commands just fine. I'd like to run it as a user though, and would also like to understand what I'm doing wrong.
Please, check that you are executing the commands with connor user, you may run whoami to see the user executing the command. (running the command with sudo changes the user to root)
In addition, I see that the user in the service file is capitalized (Connor instead of connor), this could bring other problems, and it is not needed, as a simple configuration like the one proposed by Arch Linux wiki works for user daemons.
Please find bellow the configuration I used for my ipfs daemon, (without User= and with a different Restart=, since Restart=always gave me problems while starting the daemon):
[Unit]
Description=IPFS daemon
After=network.target
[Service]
ExecStart=/usr/local/bin/ipfs daemon
Restart=on-failure
[Install]
WantedBy=default.target
I've installed the last stable version of Debian (Jessie) and /etc/inittab doesn't exist. I have read the new init system is called Sysv.
I need to launch a service with parameter, I used to add a line in inittab like
u1:23:respawn:/etc/init.d/my_service foreground
I'm trying to add this one with sysvrc-conf -p but I don't know how...
How can I do that without inittab?
Thank you so much.
Found this question by google, maybe someone else finds this usefull: The new init system for Debian Jessie is systemd. The old way in Debian Wheezy was Sysv with /etc/inittab.
To create a respawn service with systemd just create a file in /etc/systemd/system/ i.e. mplayer2.service
[Unit]
Desription=mplayer with systemd, respawn
After=network.target
[Service]
ExecStart=/usr/bin/mplayer -nolirc -ao alsa -vo null -really-quiet http://stream.sunshine-live.de/hq/mp3-128/Facebook-og-audio-tag/
Restart=always
[Install]
WantedBy=multi-user.target
and activate it
systemctl enable mplayer2.service
reboot or start it manually
systemctl daemon-reload
systemctl start mplayer2.service
If you reboot or kill the process, it will be restarted automatically some seconds later.
