复制代码 代码如下:

import httplib
import os
import time

def check_http(i):
try:
conn=httplib.HTTPConnection(i, 80, timeout=2)
conn.request("GET","/")
response = conn.getresponse()
except Exception as e:
print "server "+i+" is down"
print e
print ""
os.system('./delete_real_server.sh '+i)
else:

print response.read()

print "server "+i+" is up\n"
os.system('./add_real.server.sh '+i)

if name=="main":
httpservers=["127.0.0.1","10.0.0.1","192.168.35.28"]
while 1:
current_time=time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time()))
for i in httpservers:
check_http(i)
print current_time+" check finish\n"
time.sleep(60)
