提问by lidashuang
Express application deploy with pm2
使用pm2快速部署应用程序

数据库是mongodb
when run app with command:
使用命令运行应用程序时：
NODE_ENV=production pm2 start app.js -i max
NODE_ENV=production pm2 start app.js -i max
aften has Error: bind EADDRINUSE, this is logs, when error,

This causes app is slow, How to solve this problem, thanks very much

I don't know the port used by your application. It depends on your code. In this example, I will assume the port is 3000.
我不知道您的应用程序使用的端口。这取决于您的代码。在这个例子中，我假设端口是3000.
You need to verify if the port is already took on your system. To do that:
您需要验证该端口是否已在您的系统上使用。要做到这一点：
- On linux:
sudo netstat -nltp | grep 3000 - On OSX:
sudo lsof -i -P | grep 3000
- 在 Linux 上：
sudo netstat -nltp | grep 3000 - 在 OSX 上：
sudo lsof -i -P | grep 3000
If you have a result, you need to kill the process (kill <pid>).
如果有结果，则需要终止进程 ( kill <pid>)。
You should check if pm2 listreturns 0 process. In addition, when you do a pm2 stopAll, the socket is not released. Don't forget to do a pm2 killto be sure the daemon is killed.
您应该检查是否pm2 list返回 0 进程。此外，当您执行 a 时pm2 stopAll，不会释放套接字。不要忘记执行 apm2 kill以确保守护进程已被杀死。
$ pm2 kill
Daemon killed

操作系统
Cmd+Space -> enter: Activity Monitor -> find your app and terminate it.
Cmd+Space -> 输入：Activity Monitor -> 找到你的应用并终止它。
