实现代码如下：
#!/usr/bin/python
#coding:utf8
from subprocess import Popen, PIPE
import os
nginxpid = Popen(["pidof", "nginx"], stdout=PIPE)
nginxpid = nginxpid.stdout.read().split()
memsum = 0
for i in nginxpid:
pidfile = os.path.join("/proc/", str(i), "status")
with open(pidfile) as f:
for mem in f:
if mem.startswith("VmRSS"):
pidmem = int(mem.split()[1])
memsum += pidmem
print("%d %s" %(memsum,"KB"))
