一、查看进程所有线程的方法
1、top方法
ps -ef|grep 进程名称或者进程号
top -H -p 进程号
2、ps 方法
ps -T -p 进程号
3、pstree
pstree -Aup -h pid
4、Htop
需要安装Htop
二、杀掉某个进程的线程（未找到相关方法）
1、lsof 方法
lsof -iTCP |grep ip
列出某个ip的tcp链接，查出pid，并杀掉
2、杀死僵尸进程
查看僵死进程：
ps -A -o stat,ppid,pid,cmd | grep -e '^[Zz]'
杀掉
kill -9 pid
自动查杀僵死进程指令：
ps -A -o stat,ppid,pid,cmd | grep -e '^[Zz]' | awk '{print $2}' | xargs kill -9
