【MongoDB】3.0 配置文件相关介绍

概述：
在启动mongod和mongos时可以通过配置文件来启动控制实例。
该配置文件包含的设置同等于mongod和mongos命令选项。

使用配置文件管理mongod和mongos更容易，特别是对于大规模部署。
还可以在配置文件中添加注释来解释服务器设置选项。


使用配置文件：
要启动mongod和mongos时使用配置文件，通过-config或者-f选项指定配置文件。
例：
mongod -config /etc/mongod.conf //-config可以用-f替代
mongos -config /etc/mongos.conf

文件格式：
Mongodb的配置文件使用YAML格式。
注意：YAML不接受tab，请使用空格代替。
