各写一个shell和python脚本来监控http请求,并在服务不可用的时候重启服务。
监控的连接为:
shell脚本如下,配合crontab计划任务每一分钟执行一次检查:#!/bin/bash
# This shell is used to moniter 192.168.1.101 port 5022 & 5024
date #在crontab里用来记录log的时间
i=0
curl -s -m 10 192.168.1.101:5022/product > /dev/null #用crul测试服务是否可用
n=`echo $?` #只有在服务请求正常的情况下$?的值才为0
echo “5022 curl echo $n”
curl -s -m 10 192.168.1.101:5024/module > /dev/null
m=`echo $?`
echo “5024 curl echo $m”
if [[ “$n” -eq “$i” && “$m” -eq “$i” ]]; then
echo “api port 5022 and 5024 is ok.”
else
echo “service need restart”
/etc/init.d/serverapi restart
fi
python脚本,每隔十秒诊断一次:import requests
import os
import time
from datetime import datetime, timedelta
def restart():
try:
urls = [‘http://192.168.1.101:5022/product’, ‘http://192.168.1.101:5024/module’]
while True:
# import pdb
# pdb.set_trace()
sleep = 10
for url in urls:
print(‘get %s’%url)
r = requests.get(url,timeout=10)
if r.status_code == 200:
print(‘%s is ok…’%url)
print(‘moniter continue after 10s’)
time.sleep(sleep)
except Exception as e:
print(e.message)
print(‘%s is ERROR !!!’%url)
print(‘consoleapi will be restart’)
os.system(‘/etc/init.d/serverapi stop’)
print(‘consoleapi stoped’)
time.sleep(6)
os.system(‘/etc/init.d/serverapi start’)
if __name__ == ‘__main__’:
print(‘main’)
def main():
while True:
restart()
main()
两个脚本写的都挺烂,呵呵。贴出来主要是提醒自己,用shell或者用Python怎么方便怎么用,不要太拘泥于形式。
