如何将Node.js应用程序作为systemd服务运行？
所以我有一个我试图部署的node.js应用程序并作为systemd服务运行。
这是.service文件：
[Unit]
Description=My app
[Service]
ExecStart=/usr/local/bin/node /var/www/html/schema.js
Restart=always
User=root
Group=nogroup
Environment=PATH=/usr/bin:/usr/local/bin
Environment=NODE_ENV=production
WorkingDirectory=/var/www/html
[Install]
WantedBy=multi-user.target
不幸的是，它只是不起作用....我一直收到一个错误：

我不确定为什么它会引起这个错误。我试图手动访问该文件，并确认它位于/usr/local/bin/node，而且我可以通过运行它打开节点（我可以吗？）所以我不知道为什么它不能执行？我还检查了执行权限。所有用户组都可以这样执行......我在这里不知所措......
通过运行node确保which node在路径中
请尝试以下方法：
在您的schema.js文件中，在顶部添加以下行
#!/usr/bin/env node
这将消除在ExecStart中指定节点的需要
还要确保
chmod +x /var/www/html/schema.js
值得考虑添加到服务定义的其他选项：
PIDFile=/tmp/your-app-name.pid
KillSignal=SIGQUIT
WorkingDirectory=/var/www/html/
尝试修复使用：
Group=root
