Question

我已经完成了为python twistd应用程序编写systemd单元文件并创建它的rpm的任务。该应用程序是开源的，您可以找到它here。

我已将单位文件写为：

[Unit]
Description=ECManaged Agent for monitoring and deployment
[Service]
Type=simple
PIDFile=/opt/ecmanaged/ecagent/twistd.pid
#ExecStart=/usr/bin/twistd -y /opt/ecmanaged/ecagent/ecagentd.tac
ExecStart=\
/bin/twistd \
--nodaemon \
--pidfile=/opt/ecmanaged/ecagent/twistd.pid \
--no_save \
--python=/opt/ecmanaged/ecagent/ecagentd.tac
WorkingDirectory=/opt/ecmanaged/ecagent
[Install]
WantedBy=multi-user.target

我已将rpmbuild specfile编写为：

%define name      ecmanaged-ecagent
%define ename     ecagentd
%define pname     ecmanaged

我知道应用程序不使用setuptools有点奇怪。

他们还有init.d script和cron job使用它。你可以使用链接找到它们。

它们可以安全移除吗？如果有，怎么样？

我做得好吗？我怎样才能让它变得更好？任何指针和建议都将受到高度赞赏。

在您的服务文件中使用PIDFile是没有意义的，因为您使用的是简单类型。

PIDFile仅在您的服务类型分叉时有用（如下所示）：

[Service]
Type=forking
