ubuntu 18 custom service does not load

ubuntu 18

I have created a custom service at /etc/systemd/system/mycustomservice.service

and enable it : sudo systemctl enable /etc/systemd/system/mycustomservice.service

but the service does not load at start up, the content is:

[Unit]
After=mysql.service

[Service]
ExecStart=/home/myuser/runupdate.sh

[Install]
WantedBy=default.target

I try to execute the file /home/myuser/runupdate.sh without any issue

the permission of

/home/myuser/runupdate.sh is -rwxr--r-- /etc/systemd/system/mycustomservice.service is -rw-rw-r--

Please advise, thank you!

Solution

  • Systemd will need to know how to execute the script and what shell to use, hence there are two options Add:

    #!/bin/bash

    or

    #!/bin/sh

    to the top line of the script depending on the shell you are using. Alternatively, you can use:

    ExecStart=/bin/bash -c /home/myuser/runupdate.sh
