如何kill一个端口下所有进程

需要kill掉centos下80端口的所有进程，另做他用

 

首先我们想到 ss或者netstat list all pid under port 80

 

fuser is a simple yet powerful command line utility intended to locate processes based on the files, directories or socket a particular process is accessing. In short, it helps a system user identify processes using files or sockets.

 

No process specification given
Usage: fuser [ -a | -s | -c ] [ -n SPACE ] [ -SIGNAL ] [ -kimuv ] NAME...
[ - ] [ -n SPACE ] [ -SIGNAL ] [ -kimuv ] NAME...
fuser -l
fuser -V
Show which processes use the named files, sockets, or filesystems.

-a display unused files too
-c mounted FS
-f silently ignored (for POSIX compatibility)
-i ask before killing (ignored without -k)
-k kill processes accessing the named file
-l list available signal names
-m show all processes using the named filesystems
-n SPACE search in this name space (file, udp, or tcp)
-s silent operation
-SIGNAL send this 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]]]

fuser -v .

fuser -v -n tcp 80

fuser -k  80/tcp

fuser -v -m example.txt
