用该命令能够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]]]
