mongod启动
本来想写Replica的非测试模式的集群架构的，但是实在是手痒痒，把mongoDB的3.0给download下来了，看了一两眼文档后决定还是先大概写一点点关于启动的话题，之后写Replica的时候基本上就用mongoDB 3.0的方式+YAML的 配置方式来做了。
mongod利用mmapv1启动
这个是default的启动方式。mongod的启动参数多如牛毛，本来想有空总结一下的，我勒个去的，有些估计这辈子也用不到的场景也不知道如何写，等我再考虑一下再说吧。
准备配置文件
storage:
dbPath: C:\datam\db
engine: mmapv1
注意，engine这个地方可以不写哦，默认就是mmapv1。其余那几十个参数先不写了太多了。
启动
C:\MongoDB3\Server\3.0\bin>mongod -f C:\MongoDB3\Server\3.0\etc\conf\config.conf
执行上面的命令后：

哇啦啦，跑起来了。这个在3.0以前也这样，没啥特殊的。
mongod利用WiredTiger启动
这个是需要指定的启动方式。
准备配置文件
storage:
dbPath: C:\dataw\db
engine: wiredTiger
注意，engine这个地方设置的是wiredTiger哦。
启动
C:\MongoDB3\Server\3.0\bin>mongod -f C:\MongoDB3\Server\3.0\etc\conf\config.conf
执行上面的命令后：
C:\MongoDB3\Server\3.0\bin>mongod -f C:\MongoDB3\Server\3.0\etc\conf\config.conf
