- 问题的具体描述：
由于目前将nebula的部署方式从K8s切换成了宿主机二进制部署，所以需要进行服务托管，保证进程退出后能够正常拉起来。于是想到了配置systemd服务，配置如下：
[Unit]
Description=Nebula Metad
After=network.target
AssertPathExists=/usr/local/nebula/
[Service]
Type=simple
WorkingDirectory=/usr/local/nebula/
ExecStart=/usr/local/nebula/bin/nebula-metad --flagfile /usr/local/nebula/etc/nebula-metad.conf
Restart=always
StartLimitInterval=0
RestartSec=10
[Install]
WantedBy=multi-user.target
配置完成后，执行systemctl start nebula-metad.service后，服务无法正常拉起来，使用systemctl status nebula-metad.service查看结果如下：
● nebula-metad.service - Nebula Metad
Loaded: loaded (/etc/systemd/system/nebula-metad.service; enabled; vendor preset: disabled)
Active: activating (auto-restart) since 五 2024-12-27 14:29:38 CST; 1s ago
Process: 24121 ExecStart=/usr/local/nebula/bin/nebula-metad --flagfile /usr/local/nebula/etc/nebula-metad.conf (code=exited, status=0/SUCCESS)
Main PID: 24121 (code=exited, status=0/SUCCESS)
[root@nebula-0 nebula]# ps -ef | grep nebula
root 24129 1231 0 14:29 pts/0 00:00:00 grep --color=auto nebula
使用journalctl -u nebula-metad.service --since "5 minutes ago" 查看系统日志，如下：
12月 27 14:30:08 nebula-0 systemd[1]: Started Nebula Metad.
12月 27 14:30:08 nebula-0 systemd[1]: Starting Nebula Metad...

12月 27 14:30:59 nebula-0 systemd[1]: Started Nebula Metad.

然后手动执行/usr/local/nebula/bin/nebula-metad --flagfile /usr/local/nebula/etc/nebula-metad.conf 可以正常启动：
[root@nebula-0 nebula]# /usr/local/nebula/bin/nebula-metad --flagfile /usr/local/nebula/etc/nebula-metad.conf
[root@nebula-0 nebula]# ps -ef | grep nebula
root 24198 1 1 14:33 ? 00:00:00 /usr/local/nebula/bin/nebula-metad --flagfile /usr/local/nebula/etc/nebula-metad.conf
root 24324 1231 0 14:33 pts/0 00:00:00 grep --color=auto nebula
看metad服务的日志，手动启动，确实也成功了，没有报错

各位大佬们，可以帮忙看下是什么问题导致的吗？社区这么多人用二进制进行部署，难道都没遇到过这种问题吗？
