为 botpress 创建了一个新的 systemd 服务如果我这样做
systemctl 启动 botpress.service
它启动所有 botpress 程序，然后立即运行 ExecStop 程序。如果我删除 ExecStop=.......，Systemctl 可以正常启动。
被调用的脚本运行正常。
cat /etc/systemd/system/botpress.service
[Unit]
Description=botpess
After=docker.service
[Service]
Type=simple
TimeoutStartSec=5s
ExecStartPre=/bin/bash -c 'echo ">>>>>>>>>>> pre-starting botpress <<<<<<<<<<<<<<<"'
ExecStart=/etc/systemd/system/botpress.initd start
ExecStartPost=/bin/bash -c 'echo ">>>>>>>>>>> post-starting botpress <<<<<<<<<<<<<<<"'
ExecStop=/etc/systemd/system/botpress.initd stop
ExecStopPost=/bin/bash -c 'echo ">>>>>>>>>>> post-stopping botpress <<<<<<<<<<<<<<<"'
[Install]
WantedBy=multi-user.target
我可以将 botpress.initd 脚本放入 /etc/init.d 并让 systemctl 停止和启动，但不会在重启时重新启动。我想要做的只是调用一个简单的脚本，它可以根据需要启动和停止并在重启时启用
cat botpress.initd
#! /bin/bash -x

答案1
听起来好像是一个“一次性”命令。
这意味着您使用 systemd 启动进程，然后一旦进程启动并运行，systemd 就会接管它并在后台运行它。进程 ID 只是启动它时需要的，而不是让它保持运行。
为了测试，请运行并在此处显示结果：
systemctl status botpress.service- 如果这不是包的实际名称，请修改“botpress”。
要在启动时将该进程作为 systemd 单元启动，请sytemctl enable botpress.service在下次重新启动之前的任何时间运行。现在就可以了。

好吧，我感觉自己就像一个没有经验的刚毕业的大学生。
