node.js - 无法使用 systemctl 永远启动进程

Question

我有一个简单的 Node/Express 服务器永远运行

forever start forever_app_config.json

我的配置文件看起来像这样

{
    "uid": "myapp",
    "append": true,
    "watch": true,
    "script": "app.js",
    "sourceDir": "/data/projects/myapp"
}

一切正常。但是在尝试添加服务时( /usr/lib/systemd/system/mayapp.service)

[Unit]
Description = My Service

[Service]
User = centos
Group = centos
Environment = NODE_ENV=production
Environment = PORT=3333
ExecStart = /usr/bin/forever start /data/projects/myapp/forever_app_config.json
ExecStop = /usr/bin/forever stop myapp

[Install]
WantedBy = multi-user.target

由于某种原因它不起作用: sudo systemctl start myapp -l

myapp.service - My Service
   Loaded: loaded (/usr/lib/systemd/system/myapp.service; enabled; vendor preset: disabled)
   Active: inactive (dead) since Mon 2018-02-19 11:43:08 UTC; 12min ago
  Process: 26685 ExecStop=/usr/bin/forever stop malcazar (code=exited, status=0/SUCCESS)
  Process: 26674 ExecStart=/usr/bin/forever start /data/projects/myapp/forever_app_config.json (code=exited, status=0/SUCCESS)
 Main PID: 26674 (code=exited, status=0/SUCCESS)

和永远的日志( /home/centos/.forever/myapp.log )显示这样的错误: error: Forever detected script was killed by signal: SIGKILL .

那么，我的配置有什么问题？

最奇怪的是通过重新安装foreverjs解决了一个问题

● myapp.service - My Service
   Loaded: loaded (/usr/lib/systemd/system/myapp.service; enabled; vendor preset: disabled)
   Active: active (running) since Thu 2018-02-22 17:37:43 UTC; 4min 17s ago
 Main PID: 8121 (node)
   CGroup: /system.slice/myapp.service
           ├─8121 node /usr/bin/forever /data/projects/myapp/forever_app_config.json
           └─8244 /usr/bin/node /data/projects/myapp/app.js

我几乎可以肯定情况并非如此 sudo npm install forever -g ，但它现在对我有用，所以结束了这个问题。
