linux下自动检测mongodb 有问题就重启

import os
import time
import datetime

output = os.popen("service mongod status").read()
print( time.strftime( '%Y-%m-%d %H:%M:%S', time.localtime( time.time() ) ) )
print( output )
if "locked" in output or output=="" or "stopped" in output:
        print( "restart")
        output = os.popen("service mongod restart").read();
        print( output )
else:
        print( "ok" )

 

存为python脚本:/home/mognodb_option.py

crontab -e加:

*/2 * * * * sudo python /home/sh/mongod_restart.py
