Question

我试图在rhel7（位于AWS / EC2中）添加我的第一个服务，但是 - 服务配置不正确 - 我得到了：

[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.

此外：

[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

您能否建议如何调试systemctl服务，以免它自杀？

错误217指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为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，vasd.service启动了一种产品，该产品用于允许Linux对Active Directory进行身份验证，如果vasd.service没有启动，并且您指定了仅在Active Directory中可用的用户，则需要在其中添加该服务。您的After=行。例如：

After=network.target vasd.service
