如何调试失败的systemctl服务(代码=已退出，状态= 217/USER)? [英] How to debug a failed systemctl service (code=exited, status=217/USER)?

问题描述

我正在尝试在 rhel7 (驻留在AWS/EC2中)上添加我的第一个服务，但是-服务配置不正确-正如我得到的一样:

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]: Unit clouddirectd.service entered failed state.
Jan 09 16:09:42 ip-172-30-1-96.us-west-1.compute.internal systemd[1]: clouddirectd.service failed.

也:

[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

我的单位文件是:

[ec2-user@ip-172-30-1-96 ~]$ cat /usr/lib/systemd/system/clouddirectd.service
[Unit]
Description=CloudDirect Daemon
After=network.target

您能建议如何调试systemctl服务，使其不会自杀吗?

推荐答案

错误217表示在尝试启动服务时用户不存在.在您的情况下，您在服务中指定的用户是 clouddirect .

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

如果这不是实际的用户名(例如，如果有错字)，则可能导致此问题；如果该用户是某个外部用户存储(例如LDAP或Active Directory)的一部分，并且需要启动的服务(允许Linux服务器访问外部用户存储)尚未启动.例如，如果 vasd.service 没有启动并且您指定了仅在以下位置可用的用户，则 vasd.service 启动一种产品，该产品用于允许Linux根据Active Directory进行身份验证.您要在 After = 行中添加该服务的Active Directory.例如:

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
