问题
I'm trying to add my first service on rhel7 (which resides in AWS/EC2), but - the service is not configured correctly - as I get:
[ec2-user@ip-172-30-1-96 ~]$ systemctl status clouddirectd.service -l
● clouddirectd.service - CloudDirect Daemon
Loaded: loaded (/usr/lib/systemd/system/clouddirectd.service; enabled; vendor preset: disabled)
Active: activating (auto-restart) (Result: exit-code) since Tue 2018-01-09 16:09:42 EST; 8s ago
Main PID: 10064 (code=exited, status=217/USER)
Jan 09 16:09:42 ip-172-30-1-96.us-west-1.compute.internal systemd[1]: clouddirectd.service: main process exited, code=exited, status=217/USER

Jan 09 16:09:42 ip-172-30-1-96.us-west-1.compute.internal systemd[1]: clouddirectd.service failed.
Also:
[ec2-user@ip-172-30-1-96 ~]$ systemctl is-active clouddirectd
activating
[ec2-user@ip-172-30-1-96 ~]$ sudo systemctl list-units --type service --all | grep clouddirectd
clouddirectd.service loaded activating auto-restart CloudDirect Daemon
And my unit file is:
[ec2-user@ip-172-30-1-96 ~]$ cat /usr/lib/systemd/system/clouddirectd.service

Can you suggest how to debug the systemctl service so it won't commit suicide?
回答1:
The error 217 indicate the user did not exist at the time the service tried to start. In your case the user specified in your service is clouddirect.
Main PID: 10064 (code=exited, status=217/USER)
Jan 09 16:09:42 ip-172-30-1-96.us-west-1.compute.internal systemd[1]: clouddirectd.service: main process exited, code=exited, status=217/USER
This could be caused if that is not the actual user name (for example if it has a typo), it can also be caused if the user is part of some external user store (ex: LDAP or Active Directory) and the service that needs to start that allows the Linux server to access the external user store is not up yet. For example vasd.service starts a product used to allow Linux to authenticate against Active Directory, if vasd.service is not up and you have specified a user that is only available in Active Directory you would want to add that service in your After= line. For example:
After=network.target vasd.service
