RE: Start IOC automatically at boot

Hi,

"Is there a way to automatically start the python script with the ioc?"

-> You can simply use procServ as well to execute your python script

Objet : Start IOC automatically at boot

 

Happy new year!

I am trying to install systemd-softioc (procServ) as outlines here
https://github.com/NSLS-II/systemd-softioc. I followed the instructions
and successfully installed it on my Raspberry Pi. I installed the IOC
and can manually start the softioc, however I am not able to start the
IOC using manage-iocs. I get the following output:

softioc@raspberrypi:/epics/iocs/testIOC2$ sudo manage-iocs start
testIOC2
Starting the IOC 'testIOC2' ...
Failed to start the IOC 'testIOC2'; type 'sudo journalctl -xe' for
details.

Below is my config file and output from the journalctl


Config
---------
NAME=testIOC2
PORT=4053
HOST=raspberrypi
USER=softioc
CHDIR="/epics/iocs/testIOC2/iocBoot/ioctestIOC2"
EXEC="$CHDIR/st.cmd"

The softioc testIOC2 contains a few records which get updated from a
python script. Which brings me to my next questions. Is there a way to
automatically start the python script with the ioc?

Thank you very much for your help,

Regards
