slow_query_conveter的启动脚本部分如上，添加了service,并且ensure => running, 结果不行，手动启动/etc/init.d/xxx 是可以的。

原因在 提到，更详细的是:

  Puppet expects the initscript of the service to have a "status" command that returns 0 if the service is running and a non-zero value otherwise. This is the default behavior of puppet. Try to 

$> sudo service status
$> echo $? //Make sure you are getting the correct return values that puppet expects.
