服务器已在运行。检查C：/Rails/tmp/pids/server.pid

Question

每次当我运行2个轨不同的端口上的服务器说3000和3001

端口启动服务器后3000

Rails$ rails s -p 3000 
=> Booting Mongrel 
=> Rails 3.1.1 application starting in development on http://0.0.0.0:3000 
=> Call with -d to detach 
=> Ctrl-C to shutdown server 

当我在3001端口上运行的第二轨服务器，

Rails$ rails s -p 3001 
=> Booting Mongrel 
=> Rails 3.1.1 application starting in development on http://0.0.0.0:3001 
=> Call with -d to detach 
=> Ctrl-C to shutdown server 
A server is already running. Check /Rails/tmp/pids/server.pid. 
Exiting 

我需要删除server.pid文件，我能够在端口3001 启动轨服务器之前，有没有办法避免这种删除文件的每一次？

Answer 1

启动连续应用，如：

rails s -p 3001 -P tmp/pids/server_2.pid
