进入数据库（主库）---bin目录下执行

cd /soft/mongodb-master/bin

./mongo 172.16.1.21:27060

> use admin

>  cfg={ _id:"testrs", members:[ {_id:0,host:'172.16.1.21:27060',priority:10}, {_id:1,host:'172.16.1.22:27070',priority:9}, {_id:2,host:'172.16.1.22:27080',arbiterOnly:true}] };

> rs.initiate(cfg)

testrs:OTHER> rs.status()

创建用户

use admin;

db.createUser(  {  user: "root",  pwd: "gzyr123",roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]  });

db.createUser(  {  user: "admin",  pwd: "admin",  roles: [ { role: "root", db: "admin" } ]  });

创建数据库和用户

use test-youren;

db.createUser(  {  user: "test-youren",  pwd: "test-youren", roles: [ { role: "readWrite", db: "test-youren" } ]  });

db.createUser(  {  user: "youren_r",  pwd: "rhnn9iBPzj8PwzAD",  roles: [ { role: "read", db: "test-youren"} ]  });

db.test.insert({'id':1});

use dev-youren;

db.createUser(  {  user: "dev-youren",  pwd: "dev-youren",  roles: [ { role: "readWrite", db: "dev-youren" } ]  });

db.createUser(  {  user: "youren_r",  pwd: "rhnn9iBPzj8PwzAD",  roles: [ { role: "read", db: "dev-youren" } ]  });

db.test.insert({'id':1});

进入从库 --bin目录下执行

cd /soft/mongodb-slave/bin

./mongo 172.16.1.22:27070

testrs:SECONDARY> use test-youren

testrs:SECONDARY> db.getMongo().setSlaveOk()

testrs:SECONDARY> db.test.find()

{ "_id" : ObjectId("57eb19e242ff167f086d55ca"), "id" : 1 }

开启验证--修改配置文件

auth=true

验证权限

cd /soft/mongodb-master/bin

./mongo 172.16.1.21:27060

use test-youren;

db.auth("test-youren", "test-youren") ;
