我想对 Rails 使用端口号 localhost:3000，并且该端口号已被其他进程占用，我如何释放此端口号？
我已经运行了这个命令
ruby abc/script/server
并面临这个错误
/usr/lib/ruby/1.9.1/webrick/utils.rb:85:in `initialize': Address already in use - bind(2) (Errno::EADDRINUSE)

最佳答案
netstat -tuln | grep 3000 - 会给你进程的PID
例如:
tcp 0 0 0.0.0.0:3000 0.0.0.0:* LISTEN 5726/ruby1.9.1
这里5726是PID，使用kill -9 5726杀死它
