方法一

通过端口查询PID

通过lsof + 端口查询pid

lsof -i:8644
COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
python  14306 work    3u  IPv4 332406      0t0  TCP *:8644 (LISTEN)

通过进程查到详细的执行程序

cd /proc/14306

通过信息得出：/home/work/.jumbo/bin/python2.7 python执行该文件

  • cwd符号链接的是进程运行目录；
  • exe符号连接就是执行程序的绝对路径；
  • cmdline就是程序运行时输入的命令行命令；
  • environ记录了进程运行时的环境变量；
  • fd目录下是进程打开或使用的文件的符号连接。

或者通过pid直接得出

方法二

使用netstat来查看端口的pid

1
netstat -antlp|grep 8087
