How to execute some command always after hard reboot (ubuntu server)?

  • 772

I am facing an issue that everytime I hard restart my server (maybe went bananas due to out of memory, ddosed etc) supervisor fails to run. And the reason for that is identified and simply /var/run/supervisor directory is deleted.

I learned that /var/run folders are deleted on hard reboot (via ec2 panel for instance force stop then start), so my humble question is:

How can I execute this mkdir /var/run/supervisor after every hard reboot ? Where is the perfect place to add such logic. I guess it is not /etc/profile for sure

(the rest works fine, supervisor is configured as service + uses unix sock at var/run/supervisor/supervisor.sock)

My ubuntu version:

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.2 LTS
Release:        20.04
Codename:       focal

    In Ubuntu 20 I would expect that supervisor is started as a systemd service unit.

    In the service unit for supervisor you need to specify that the directory is created: (the unit name might be different)

    sudo systemctl edit --full supervisor

    and add a directive:

    RuntimeDirectory=supervisor
