Question

我想使用port no localhost：3000 for rails并且已经采取了其他进程如何免费使用此端口？

我已经运行了这个命令

ruby abc/script/server

并面临此错误

Answer 1

netstat -tulpn | grep 3000 - 将为您提供流程的PID

例如：

tcp    0   0 0.0.0.0:3000    0.0.0.0:*  LISTEN      5726/ruby1.9.1

此处5726是PID，使用kill -9 5726

将其删除

Answer 3

尝试这样的事情：

lsof -wni tcp:3000

将显示如下：

COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
ruby    3824 rony    9r  IPv4  50665      0t0  TCP *:3001 (LISTEN)

然后使用此PID：

终止此操作

kill -9 3824

谢谢！
