如何将 node.js 应用程序作为后台服务运行? [英] How do I run a node.js app as a background service?
问题描述
由于这篇文章多年来受到了很多关注，我在这篇文章的底部列出了每个平台的最佳解决方案.
Since this post has gotten a lot of attention over the years, I've listed the top solutions per platform at the bottom of this post.

我希望我的 node.js 服务器在后台运行，即:当我关闭终端时，我希望我的服务器继续运行.我用谷歌搜索了这个并想出了这个教程，但它不起作用如预期.因此，我认为我没有使用该守护程序脚本，而是使用了输出重定向(2>&1 >> file 部分)，但这也没有退出 - 我得到了一个空行在我的终端中，就像在等待输出/错误一样.
I want my node.js server to run in the background, i.e.: when I close my terminal I want my server to keep running. I've googled this and came up with this tutorial, however it doesn't work as intended. So instead of using that daemon script, I thought I just used the output redirection (the 2>&1 >> file part), but this too does not exit - I get a blank line in my terminal, like it's waiting for output/errors.
我也尝试将进程置于后台，但是一旦我关闭终端，进程也会被终止.
I've also tried to put the process in the background, but as soon as I close my terminal the process is killed as well.
当我关闭本地计算机时，如何让它继续运行?
So how can I leave it running when I shut down my local computer?
最佳解决方案:
- Systemd (Linux)
- Launchd (Mac)
- node-windows (Windows)
- PM2 (Node.js)

2015 年回答:几乎每个 Linux 发行版都带有 systemd，这意味着永远不再需要 monit、PM2 等 - 您的操作系统已经处理了这些任务.
2015 answer: nearly every Linux distro comes with systemd, which means forever, monit, PM2, etc are no longer necessary - your OS already handles these tasks.
制作一个 myapp.service 文件(显然，用您的应用程序名称替换myapp"):
Make a myapp.service file (replacing 'myapp' with your app's name, obviously):
[Unit]
Description=My app
[Service]
ExecStart=/var/www/myapp/app.js
Restart=always
User=nobody
# Note Debian/Ubuntu uses 'nogroup', RHEL/Fedora uses 'nobody'
Group=nogroup
Environment=PATH=/usr/bin:/usr/local/bin
Environment=NODE_ENV=production
WorkingDirectory=/var/www/myapp
[Install]
WantedBy=multi-user.target
请注意，如果您是 Unix 新手: /var/www/myapp/app.js 应该有 #!/usr/bin/env 节点 在第一行并打开可执行模式chmod +x myapp.js.
Note if you're new to Unix: /var/www/myapp/app.js should have #!/usr/bin/env node on the very first line and have the executable mode turned on chmod +x myapp.js.
将您的服务文件复制到/etc/systemd/system.
Copy your service file into the /etc/systemd/system.
使用 systemctl start myapp 启动它.
使用 systemctl enable myapp 使其在启动时运行.
Enable it to run on boot with systemctl enable myapp.
使用 journalctl -u myapp
这取自 我们如何在 Linux 上部署节点应用程序，2018 版，其中还包括生成 AWS/DigitalOcean/Azure CloudConfig 以构建 Linux/节点服务器的命令(包括 .service 文件).
