使用pm2
快速部署应用程序数据库是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

这导致app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
。
您需要验证您的系统上是否已使用该端口。要做到这一点:
sudo netstat -nltp | grep 3000
sudo lsof -i -P | grep 3000
如果您有结果,则需要终止该过程(kill <pid>
)。
您应该检查pm2 list
是否返回0进程。此外,当您执行pm2 stopAll
时,套接字不会被释放。不要忘记做pm2 kill
以确保守护程序被杀死。
$ pm2 kill
Daemon killed
