快速应用程序部署pm2 https://github.com/Unitech/pm2
数据库是mongodb
当使用命令运行应用程序时：
NODE_ENV=production pm2 start app.js -i max
经常有错误：绑定EADDRINUSE，这是日志，当错误时，
[app err (l0)] js:1073:26

这导致应用程序很慢，如何解决这个问题，非常感谢
我不知道您的应用程序使用的端口。这取决于你的代码。在这个例子中，我假设端口是3000.
您需要验证该端口是否已在您的系统上占用。要做到这一点：
- 在Linux上：
sudo netstat -nltp | grep 3000
- On OSX:
sudo lsof -i -P | grep 3000
如果有结果，则需要终止该进程（kill <pid>).
你应该检查是否pm2 list返回 0 进程。此外，当您执行pm2 stopAll，套接字未释放。不要忘记做一个pm2 kill确保守护进程被杀死。
$ pm2 kill
Daemon killed
