### 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

- 把生产的key复制到/usr/local/mongodb/key
- 设置key文件的权限为600
- 修改key文件的属主属组

### 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
>
> show dbs
admin (empty)
local 1.078GB
test (empty)
> use admin
switched to db admin
> db.addUser("zhuima","zhuima")
WARNING: The 'addUser' shell helper is DEPRECATED. Please use 'createUser' instead
Successfully added user: { "user" : "zhuima", "roles" : [ "root" ] }
>### 主服务器配置文件
[root@redis mongodb]# sed -e '/^$/d;/^#/d' /etc/mongod.conf port=27017 dbpath=/mongo/data/mongodb_data/ logpath=/mongo/data/mongodb_log/mongodb.log pidfilepath=/usr/local/mongodb/mongo.pid fork=true logappend=true shardsvr=true directoryperdb=true replSet=zhuima keyFile=/usr/local/mongodb/key bind_ip=192.168.58.30
### 从服务器上配置文件
[root@mongo1 data]# vim /etc/mongod.conf [root@mongo1 data]# sed -e '/^$/d;/^#/d' /etc/mongod.conf logpath=/var/log/mongodb/mongod.log logappend=true fork=true dbpath=/mongo/data pidfilepath=/var/run/mongodb/mongod.pid bind_ip=192.168.58.10 replSet = zhuima keyFile = /mongo/data/key
### 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

zhuima:SECONDARY>### 关于mongodb 复制集 + auth的配置要感谢灿哥的指点
灿哥博客：http://www.shencan.net/
### 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
