Nodejs应用程序错误:使用pm2部署时绑定EADDRINUSE

Question

使用pm2部署Express应用程序

数据库是mongodb

使用命令运行app时:

NODE_ENV=production pm2 start app.js -i max

aften有错误:绑定EADDRINUSE,这是日志,当出错时,

[app err (l0)] js:1073:26
[app err (l1)]     at Object.30:1 (cluster.js:587:5)
[app err (l2)]     at handleResponse (cluster.js:171:41)

这导致app很慢,如何解决这个问题,非常感谢

Answer 1

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,我将假设端口是3000.

您需要验证端口是否已在您的系统上使用.要做到这一点:

• 在linux上: sudo netstat -nltp | grep 3000
• 在OSX上: sudo lsof -i -P | grep 3000

如果有结果,则需要终止进程(kill <pid>).

你应该检查是否pm2 list返回0进程.此外,当您执行a时pm2 stopAll,套接字不会被释放.不要忘记做一个pm2 kill以确保守护程序被杀死.

$ pm2 kill
Daemon killed

Cmd + Space->输入：活动监视器->查找您的应用并终止它。
