else
echo "please check the log"
fi

esac
onstart.js文件内容：
use admin;
db.shutdownServer()

运行：
/etc/init.d/mongod stop
有如下报错信息：
connecting to: test
switched to db admin
Thu Apr 12 14:42:16 DBClientCursor::init call() failed
Thu Apr 12 14:42:16 query failed : admin.$cmd { shutdown: 1.0 } to: 127.0.0.1:27017
server should be down...
Thu Apr 12 14:42:16 trying reconnect to 127.0.0.1:27017
Thu Apr 12 14:42:16 reconnect 127.0.0.1:27017 failed couldn't connect to server 127.0.0.1:27017
bye
please check the log

为什么会有这个报错信息那

你执行完 /etc/init.d/mongod stop

再执行一下：
ps -ef |  grep mongod |grep -v "grep"

看输出是什么。

应该没有什么大问题，
不过，不知道你执行stop的时候，为什么要先启动一下mongodb后，再检查，再关闭？
个人觉得，stop/start的时候直接先ps -fe | grep mongod |grep -v "grep"|wc -l 判断一下mongo是否启动

en,我找到问题了，那个脚本有点问题，
mongo admin --eval db.shutdownServer()
把这个问题解决了
