验证
mongo用–auth选项开启认证，但是在开启认证之前必须有一个有userAdminAnyDatabase角色的管理员账户。
因此首先我们要创建一个账户，然后修改配置文件加上auth选项，重启mongo。
mongo内置用户角色说明：
- 数据库用户角色：read、readWrite；
- 数据库管理角色：dbAdmin、dbOwner、userAdmin；
- 集群管理角色：clusterAdmin、clusterManager、clusterMonitor、hostManager；
- 备份恢复角色：backup、restore；
- 所有数据库角色：readAnyDatabase、readWriteAnyDatabase、userAdminAnyDatabase、dbAdminAnyDatabase
- 超级用户角色：root （如果用户同时有dbOwner 、userAdmin、userAdminAnyDatabase三个角色，就间接或直接提供了系统超级用户的访问）
创建用户
mongos> use admin; switched to db admin mongos> db.createUser({ ... user: "admin", ... pwd: "admin", ... roles: [{role:"root",db:"admin"}] ... }); Successfully added user: { "user" : "admin", "roles" : [ { "role" : "root", "db" : "admin" } ] }
关闭三台机器上的mongod和configsvr以及mongos服务
将配置文件注释的key选项打开
security: keyFile: /data/mongodb/config/data/keyfile authorization: enabled
生成keyfile
openssl rand -base64 753 >keyfile
chmod 600 keyfile
注意权限600
将keyfile 复制到各自的目录 （所有机器用一个key）
configsrv mongos shard0 shard1 shard2
