I want to run a script at system startup in a Debian 9 box. My script works when run standalone, but fails under systemd.
My script just copies a backup file from a remote server to the local machine:
#!/bin/sh set -e /usr/bin/sshpass -p "PASSWORD" /usr/bin/scp -p USER@10.0.0.2:ORIGINPATH/backupserver.zip DESTINATIONPATH/backupserver/ Just for privacy I replaced password, user, and paths above.
I wrote the following systemd service unit:
[Unit] Description=backup script [Service] Type=oneshot ExecStart=PATH/backup.sh [Install] WantedBy=default.target Then I set permissions for the script:
chmod 744 PATH/backup.sh And installed the service:
chmod 664 /etc/systemd/system/backup.service systemctl daemon-reload systemctl enable backup.service When I reboot the script fails:
● backup.service - backup script Loaded: loaded (/etc/systemd/system/backup.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Sat 2017-05-13 13:39:54 -03; 47min ago Main PID: 591 (code=exited, status=1/FAILURE) Result of journalctl -xe:

What could be wrong?

Solved guys. There was 2 problems:
1 - I had to change the service unit file to make the service run only after network was up. The unit section was changed to:
[Unit] Description = World server backup Wants = network-online.target After = network.target network-online.target 2 - The root user did not have the remote host added to the known host list, unlike the ordinary user I used to test the script.
Failed with result 'exit-code' you could try this on your last line:
# REQUIRED FOR SYSTEMD: 0 means clean no error exit 0 You may also need to add:
Type=forking to the systemd entry similar to:
If your service or script does not fork add a & at the end to run it in the background, and exit with 0 fast. Otherwise it will be like a startup that times out and takes forever / seems like frozen service.
