我有这个service文件：

[Unit]
Description=MyService

[Service]
User=root
WorkingDirectory=/path/to/workingdir
ExecStart=/path/to/myservice

[Install]
WantedBy=multi-user.target

当我myservice从命令行启动时，它会启动并取消恶魔化。当我用-d（用于调试）启动它时，它不会去恶魔化，但在按 Enter 时停止。

但是，当我将其放入文件myservice中时service，它根本不会启动：

[root@localhost bin]# systemctl status myservice.service 
● myservice.service - MyService
   Loaded: loaded (/etc/systemd/system/myservice.service; enabled; vendor preset: disabled)
   Active: inactive (dead) since Tue 2023-08-22 09:20:21 CEST; 4min 1s ago
  Process: 1790032 ExecStart=/path/to/myservice (code=exited, status=0/SUCCESS)
 Main PID: 1790032 (code=exited, status=0/SUCCESS)

Aug 22 09:20:21 localhost.localdomain systemd[1]: Started MyService
Aug 22 09:20:21 localhost.localdomain myservice[1790033]: myservice started with:
Aug 22 09:20:21 localhost.localdomain myservice[1790033]: current working dir: /path/to/workingdir
Aug 22 09:20:21 localhost.localdomain systemd[1]: myservice.service: Succeeded.

当使用 启动它时-d，它会启动，但 CPU 使用率会提高到 90%。

我应该如何service为自己守护进程的程序配置文件？

以前，支持通配符。例如

  • sudo systemctl stop 'vncserver@*'
  • sudo systemctl disable 'vncserver@*'

现在在 Rocky Linux（和 Centos-8 应该相同）中，用户列在“/etc/tigervnc/vncserver.users”中，而不是具有单独的服务文件。我可以扫描文件，但是否有一个命令可以完成所有操作？

我有一个 Ubuntu 18.04 操作系统，我已经按照此处prometheus的步骤安装了它（我只是更改了链接和版本）。

但是当我尝试使用 启动服务时sudo systemctl start prometheus，出现以下错误/var/log/syslog：

Jan 11 21:46:57 ZiZi prometheus[11585]: level=error ts=2020-01-11T18:16:57.051Z caller=main.go:727 err="error loading config from \"/etc/prometheus/prometheus.yml\": couldn't load configuration (--config.file=\"/etc/prometheus/prometheus.yml\"): parsing YAML file /etc/prometheus/prometheus.yml: yaml: unmarshal errors:\n  line 15: field static_configs not found in type config.plain"

这是/etc/prometheus/prometheus.yml（如上述教程中所述）的内容：

global: 
 scrape_interval: 15s # Set the scrape interval to every 15 seconds.
 evaluation_interval: 15s # Evaluate rules every 15 seconds. 
 scrape_timeout: 15s # scrape_timeout is set to the global default (10s).

# A scrape configuration containing exactly one endpoint to scrape:# Here it's Prometheus itself.
scrape_configs:
 # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
 - job_name: 'prometheus'

# metrics_path defaults to '/metrics'
 # scheme defaults to 'http'.

static_configs:
 - targets: ['localhost:9090']

如何修复错误？
