### 开启auth认证的mongodb的复制集
### 注意点
- 服务器节点之前时间要同步
- 开启防火墙的一定要允许通过
- 开启selinux的也要进行设置
- 建立双击互信模式最好不过
### 提前要做的事情
-
生产高端大气上档次的keyFile文件

### 把key文件复制到另外一个节点上去
-
- 注意属组属主
-
- 创建一个全局账户

### 重启mongodb服务观察结果
-
- 初始化副本集

> rs.initiate()

- 由下面的可以看出，keyFile默认就包含了开启auth功能

### 关于mongodb 复制集 + auth的配置要感谢灿哥的指点
### 后记：
-
生产环境中虽说mongdb不对外服务，但是加上auth认证总归是有好处的
-
还记得曾经被乌云爆过的痛么~
-
后续博客将会讲诉索引记忆分片操作
