MongoDB YAML格式的配置文件

根据官网的提示内容，默认的配置文件内容为

---

注意：boolean值为true或者false，首字母不能大写

　　systemLog.path为一个文件名，不能为一个文件夹，如果该文件已存在，会创建一个新的带日期的文件

　　有了这个基础，启动时就可以看启动日志文件来查看到底是哪里的配置有问题不能启动

　　processManagement.pidFilePath为一个文件地址，不存在也没问题

　　net.ssl最好全部注释掉，暂时不用ssl

　　security下最好也注释掉，否则需要配置全部安全内容，以及keyFile一定要存在。

　　storage.repairPath一定要是storage.dbPath的子目录，且目录需要存在。

　　replication是复制，副本启动，注释掉

　　记得注释掉一个引擎

　　这样就可以启动了

mongodb3.x版本后就是要yaml语法格式的配置文件，下面是yaml配置文件格式如下：

官方yaml配置文件选项参考：https://docs.mongodb.org/manual/ ... #configuration-file

只能使用空格，不支持tab键
