【问题描述】：

我需要让 systemd 上的服务保持运行，因为它没有激活？由于我遵循documentation的建议，为什么会发生这种情况，以下是代码：

服务代码：

# Contents of /etc/systemd/system/quark.service
[Unit]
Description=Quark
After=network.target

[Service]
Type=simple
User=cto
ExecStart=/usr/local/bin/python3.9 /var/net/
Restart=always

[Install]
WantedBy=multi-user.target

状态码：

【问题讨论】：

您的服务抱怨启动请求太快。是否配置正确？老实说，我个人不了解 Quark，但如果是重试/重启率，您可能想要更改的选项是 RestartSec。这是一个相关的帖子：stackoverflow.com/a/39284869

【解决方案1】：

ExecStart 应该是要执行的命令：

systemd manpages:

ExecStart=

Commands with their arguments that are executed when this service is started.

这一节：

ExecStart=/usr/local/bin/python3.9 /var/net/

应该是：

ExecStart=/usr/local/bin/python3.9 path_to_python_script.py
