linux关闭占用端口的进程

[root@izuf64lmg25t75c8db3hxcz workspace]# lsof -i:9999
COMMAND   PID USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
python3 11902 root    3u  IPv4 9435173      0t0  TCP *:distinct (LISTEN)
python3 11902 root    5u  IPv4 9451420      0t0  TCP izuf64lmg25t75c8db3hxcz:distinct->115.200.48.232:ibm-mgr (CLOSE_WAIT)
[root@izuf64lmg25t75c8db3hxcz workspace]# kill -9 11902

lsof -i:端口号

kill -9 pid

当然也有另一种不用查看pid的方法

kill -9 `lsof -i:9999 awk ‘NR==2{print $2}’`
