查看pid

root@ubuntu:~# pidof mongod
4889
root@ubuntu:~#

根据pid查看进程的占用的端口：

root@ubuntu:~# netstat -antup|grep 4889
tcp        0      0 0.0.0.0:27017           0.0.0.0:*               LISTEN      4889/mongod         
tcp        0      0 127.0.0.1:27017         127.0.0.1:57248         ESTABLISHED 4889/mongod         
root@ubuntu:~#

查看某个端口被哪个进程占用:

root@ubuntu:~# lsof -i:27017
COMMAND  PID    USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
mongod  4889 mongodb   11u  IPv4  79019      0t0  TCP *:27017 (LISTEN)
mongod  4889 mongodb   33u  IPv4  79895      0t0  TCP localhost:27017->localhost:57248 (ESTABLISHED)
mongo   4922    root    6u  IPv4  79894      0t0  TCP localhost:57248->localhost:27017 (ESTABLISHED)
