linux根据进程号查端口的2种方法

[db02@centos1 conf]$ lsof -i|grep 57081
java    57081 db02   72u  IPv4 364481      0t0  TCP *:7199 (LISTEN)
java    57081 db02   85u  IPv4 364582      0t0  TCP 10.6.6.11:9042 (LISTEN)
java    57081 db02  159u  IPv4 364576      0t0  TCP 10.6.6.11:afs3-fileserver (LISTEN)
[db02@centos1 conf]$ netstat -anp|grep 57081
