UBUNTU下MONGODB出現PHP Fatal error: Uncaught exception 'MongoConnectionException' with message 和 Authentication failed on database 'admin' with username

MONGO 遠程連接服務器，出現：

PHP Fatal error:  Uncaught exception 'MongoConnectionException' with message 'Failed to connect to: 63.141.xx.xxx:27017: Authentication failed on database 'admin' with username 'xxx': auth fails' in /var/www/data/update_data.php:25
Stack trace:#0 /var/www/data/update_data.php(25): Mongo->__construct('mongodb://seole...')
#1 {main}

 

Authentication failed on database 'admin' with username

我明明連接的是XXX數據集合。 不是admin數據庫。為毛出現連接Admin失敗。

GOOGLE，原來是有些版本的mongo 搭配 linux后，如果不指定連接數據集，默認連接的是admin數據集，所以在連接字符串中就得指明要連接數據集。

代碼由

$mongo_server = "mongodb://username:[e-mail]:27017";
$m_f = new Mongo($mongo_server); //
$db_f = $m_f->eTao;
$collection_f = $db_f->etao_data;

改為


$mongo_server = "mongodb://username:[e-mail]:27017/eTao";
$m_f = new Mongo($mongo_server); //
$db_f = $m_f->eTao;
$collection_f = $db_f->etao_data;
