Ruby on rails 如何在Ubuntu中释放端口

我想对rails使用端口号localhost:3000，这已经是另一个过程了。如何释放这个端口号

我已经运行了这个命令

ruby abc/script/server

面对这个错误

netstat-tulpn | grep3000将为您提供流程的PID

e、 g:

---

这里

5726

是PID，使用

kill-95726

netstat-tulpn | grep3000

-杀死它将为您提供进程的PID

e、 g:

---

这里

5726

是PID，使用

kill-95726

杀死它您也可以在不同的端口上启动rails服务器

rails server -p 4000

---

您还可以在不同的端口上启动rails服务器

rails server -p 4000

---

试着这样做：

lsof -wni tcp:3000

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

将显示如下：

lsof -wni tcp:3000

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

然后用这个

PID

杀死它：

kill -9 3824

谢谢
