Ncat: bind to :::8888: Address already in use. QUITTING.

原因：

端口被占用

解决：

1.找到占用进程： netstat -nap | grep 进程id

[root@master ~]# netstat -nap | grep 8888
tcp        0      0 0.0.0.0:8888            0.0.0.0:*               LISTEN      33031/nc
tcp6       0      0 :::8888                 :::*                    LISTEN      33031/nc

2.杀死进程

[root@master ~]# kill -9 33031
