在后台运行节点服务器

Question

我希望节点服务器在后台运行。我已经读过该线程：How do I run a Node.js application as its own process?

我收到错误：

systemd[10948]: myapp_test.service: Failed to determine group credentials: No such process
systemd[10948]: myapp_test.service: Failed at step GROUP spawning /some-directory/index.js: No such process

myapp_test.service文件：

[Unit]
Description=Something

[Service]
ExecStart=/some-directory/index.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=development
WorkingDirectory=/some-directory/

[Install]
WantedBy=multi-user.target

我尝试将“ nobody”作为组，我尝试省略用户和组，但出现此错误：

systemd[11543]: myapp_test.service: Failed to execute command: Permission denied
systemd[11543]: myapp_test.service: Failed at step EXEC spawning /some-directory/index.js: Permission denied

如果我转到some-directory并键入node index.js，一切正常（包括NODE_ENV =开发设置）。

您似乎试图将服务作为系统实例运行，但是服务本身定义为用户实例（通过使用User =）

尝试将.service文件复制到/ etc / systemd / user使用systemctl --user选项运行和监视系统。

为了使服务在用户的最后一个会话关闭后仍保留，请在此处查看loginctl：https://wiki.archlinux.org/index.php/Systemd/User
