Mongodb 3.2.9开启用户权限认证问题的步骤详解

>show dbs 
##看到有如下数据 
admin (empty) 
comment 0.203125GB 
dbtest (empty) 
foo 0.203125GB 
local (empty) 
test 0.203125GB 
>use admin 
switched to db admin 
> db.addUser('admin','12345678') ##添加用户 
Mon Nov 5 23:40:00 [FileAllocator] allocating new datafile /data/db/admin.ns, filling with zeroes... 
{ 
 "user" : "admin", 
 "readOnly" : false, 
 "pwd" : "89e41c6c28d88d42c21fe501d82969ea", 
 "_id" : ObjectId("5097ddd00342c63efff3fbfb") 
} 
##之后运行 
>showdbs 
Mon Nov 5 23:45:13 uncaught exception: listDatabases failed:{ "errmsg" : "need to login", "ok" : 0 } ##提示需要登录 
 
添加--auth 启动 
./mongod -auth 
./mongo 
 
>use admin 
switched to db admin 
> db.auth('admin','12345678') ##用添加的账户密码查看 
Mon Nov 5 23:49:32 [conn56] authenticate db: admin { authenticate: 1, nonce: "304f5242601fafa4", user: "admin", key: "58260df384b1146466efca5c90a5ff05" }

##1 使用超级用户连接mongodb 
/*mongodb连接*/ 
$m = new Mongo("mongodb://admin:12345678@192.168.138.35:27017"); 
/*选择melon数据库*/ 
$db = $m->melon; 
/*集合*/ 
$collection = melonco; 
/*选择数据库里面的集合，相当于表*/ 
$collection = $db->$collection; 
$array = array('name'=>'melon','age'=>'24','sex'=>'Male','birth'=>array('year'=>'1988','month'=>'07','day'=>'13')); 
$collection->insert($array); 
$cursor = $collection->find(); 
foreach ($cursor as $id => $value) { 
 echo "$id: "; var_dump($value); echo "<br>";  
} 
 
 
###2 使用数据库用户 
/*mongodb连接*/ 
$m = new Mongo("192.168.138.35:27017"); 
/*选择comment*/ 
$db = $m->melon; 
/*连接数据库*/ 
$db->authenticate("melon", "melon"); 
/*选择t数据库里面集合，相当于表*/ 
$collection = $db->melonco; 
$array = array('name'=>'melon_son','age'=>'0','sex'=>'Male','birth'=>array('year'=>'201X','month'=>'07','day'=>'13')); 
$collection->insert($array); 
$cursor = $collection->find(); 
 
foreach ($cursor as $id => $value) { 
 echo "$id: "; var_dump($value); echo "<br>";  
} 

> use admin 
switched to db admin 
> var schema = db.system.version.findOne({"_id" : "authSchema"}) 
> schema.currentVersion = 3 
3 
> db.system.version.save(schema) 
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 }) 

> use admin 
> db.auth('root','123456')
