Rails:地址已在使用 - bind(2) (Errno::EADDRINUSE) [英] Rails: Address already in use - bind(2) (Errno::EADDRINUSE)

问题描述

我正在尝试使用 Puma Web 服务器部署 Rails 应用程序.当尝试使用配置文件 bundle exec puma -C config/puma.rb 启动 Puma 服务器时，我收到地址已被使用的错误.

I am trying to deploy Rails app with the Puma web server. When trying to start Puma server with a config file bundle exec puma -C config/puma.rb I get an error that the address is already in use.

有人知道如何解决这个问题吗?

Does someone know how to fix this?

推荐答案

You need to use kill -9 59780 with 59780 替换为找到的PID号(使用lsof -wni tcp:3000 查看哪个进程使用了​​ 3000 端口并获取进程 PID).

You need to use kill -9 59780 with 59780 replaced with found PID number (use lsof -wni tcp:3000 to see which process used 3000 port and get the process PID).

或者您可以修改您的 puma 配置，将 tcp 端口 tcp://127.0.0.1:3000 从 3000 更改为 9292 或其他未使用的端口.

Or you can just modify your puma config change the tcp port tcp://127.0.0.1:3000 from 3000 to 9292 or other port that not been used.

或者您可以使用以下命令启动您的 rails 应用程序:

Or you can start your rails app by using:

bundle exec puma -C config/puma.rb -b tcp://127.0.0.1:3001
