Question

我的LAN上有一个Rails登台服务器，如下所示：

rails server --binding=0.0.0.0 -p 3000

我现在想按如下所示在我的LAN中打开第二个并发的Rails服务器：

rails server --binding=0.0.0.0 -p 3001

不幸的是，我收到此错误消息：

...
=> Booting Puma
=> Rails 5.1.1 application starting in development on http://0.0.0.0:3001
=> Run `rails server -h` for more startup options
A server is already running. ...

仅当我在两台服务器上都使用--binding=0.0.0.0时，该错误才存在，如果我希望LAN可以访问它，则必须这样做。

如何在同一台计算机上向局域网打开多个Rails服务器，而不仅仅是localhost？

编辑：

尝试使用Vasfed的解决方案后，例如

rails server --binding=0.0.0.0 -p 3000 --pid=tmp/pids/server0.pid
rails server --binding=0.0.0.0 -p 3001 --pid=tmp/pids/server1.pid

问题仍然存在，但是这次我有更多信息。似乎与打开端口9292有关...

Rails检查pid文件是否已经存在。要运行单个应用程序的两个副本，您也应该更改pid：

rails server --binding=0.0.0.0 -p 3000 --pid=tmp/pids/server1.pid
rails server --binding=0.0.0.0 -p 3001 --pid=tmp/pids/server2.pid

具有绑定的多个并发Rails服务器
