监控Tomcat服务，自动重启脚本

针对测试环境程序异常关闭，由于测试环境安装Supervisor太费劲了，就自己写了一个小脚本，希望能解决大家的问题，脚本内容如下：

#!/usr/bin/python
# coding=utf-8
import subprocess
import datetime
import time

App = {"appstock.soa.360buy.com": "/export/Domains/appstock.soa.360buy.com/server1/bin/"}

for key in App.keys():
  command = "ps -ef | grep " + key
   res = subprocess.Popen(command, stdout=subprocess.PIPE, shell=True)
  tomcats = res.stdout.readlines()
  counts = len(tomcats)
  dt = datetime.datetime.now()
  fp = open("/root/tomcat_app.txt", "a")
  if counts < 3:
  fp.write(key + " stop at %s\n" % dt.strftime("%Y-%m-%d %H:%M:%S"))
  stop = App[key] + "/stop.sh"
  start = App[key] + "/start.sh"
  subprocess.Popen(stop, shell=True)
  time.sleep(10)
  subprocess.Popen(start, shell=True)
 else:
  fp.write(key + " is running at %s\n" % dt.strftime("%Y-%m-%d %H:%M:%S"))
 fp.close()

1  App是一个字典，key是程序域名，value是启动脚本所在的目录地址（绝对地址）

2 设置定时任务

   crontab -e

    */5 * * * *  python /root/monitor.py    (脚本的绝对地址)  如果执行不写python的话，记得给脚本可执行的权限

   如果crontab没有生效，重启一下  /etc/init.d/crond restart
