Question

我想使用NodeJS执行pm2 restart IDOFMYAPP ......这可能吗？

类似的东西：

var sys = require('sys')
var exec = require('child_process').exec;
function puts(error, stdout, stderr) { sys.puts(stdout) }
exec("pm2 restart IDOFMYAPP", puts);

实际上，我想创建一个按钮来执行上面的代码，但是我的按钮位于我想要重启的应用程序的视图中...

你可以这样做：

var shell = require('shelljs');

shell.exec('pm2 restart IDOFMYAPP', function(code, output) {
  console.log('Exit code:', code);
  console.log('Program output:', output);
});

使用Node.js执行PM2命令
