用该命令可以找出使用端口的进程。可写脚本监控，停止端口及进程~

例如：fuser -n tcp 3306 | ps aux | grep 24594 | grep -v "grep"

若要将使用该端口的进程kill

例如：fuser -k -n tcp 3306

usage: fuser [ -a | -s ] [ -n space ] [ -signal ] [ -kimuv ] name ...

[ - ] [ -n space ] [ -signal ] [ -kimuv ] name ...

fuser -l

fuser -V

-a display unused files too

-k kill processes accessing that file

-i ask before killing (ignored without -k)

-l list signal names

-m mounted FS

-n space search in the specified name space (file, udp, or tcp)

-s silent operation

-signal send signal instead of SIGKILL

-u display user ids

-v verbose output

-V display version information

-4 search IPv4 sockets only

-6 search IPv6 sockets only

- reset options

udp/tcp names: [local_port][,[rmt_host][,[rmt_port]]]
