比如要查看nginx主进程，lsof -p pid
root@localhost:~/xly# ps aux|grep nginx
root 5847 0.0 0.0 92428 1728 ? Ss 12月07 0:00 nginx: master process /usr/sbin/nginx
root 5848 0.0 0.0 93020 3036 ? S 12月07 0:49 nginx: worker process
root 5849 0.0 0.0 93020 3036 ? S 12月07 0:51 nginx: worker process
root 5851 0.0 0.0 93020 3032 ? S 12月07 0:46 nginx: worker process
root 5852 0.0 0.0 93020 3036 ? S 12月07 0:48 nginx: worker process
root 16635 0.0 0.0 13424 948 pts/5 S+ 16:41 0:00 grep nginx
root@localhost:~/xly# lsof -p 5847

比如进程名叫aaa，可以执行如下命令：ps -ef|grep aaa，
如果有内容说明活着如果你知道进程占用的端口号，比如7777，可以执行:netstat -anp | grep 7777，检查有没有程序占用该端口，若有的话，看pid或pname是否是你想要找的
如果想要找的是某个服务，比如nfs、smb等，可以用service nfs status查看
