4、PHP测试分片集群

对数据库test_db2新建两个用户，一个只读用户，一个读写用户

user test_db2

#可读可写

db.createUser(

       {

               user:"ybl",

               pwd:"6055",

               roles:[{"role":"readWrite","db":"test_db2"}]

        }

)

#只读

db.createUser(

       {

               user:"xjl",

               pwd:"6055",

               roles:[{"role":"read","db":"test_db2"}]

       }

)

php安装MongoDB扩展查看此处

<?php

try{    $conn=new\MongoClient("mongodb://ybl:6055@127.0.0.143:20000,127.0.0.144:20000",array("db"=>"test_db2"));

}catch(MongoConnectionException$e){

       echo$e->getMessage();

}

如果认证未通过，则捕获到异常
