配置用户和使用 PHP 连接到 Mongo 的问题 [英] Trouble with configuring users and connecting to Mongo with PHP

问题描述

我在我的 ubuntu 服务器上安装了 mongo 3.0.0.我尝试使用 PHP(安装了适当的库)连接到 mongo 以学习新东西.不幸的是，我不能再进一步了.我的用户配置如下所示:

I installed mongo 3.0.0 on my ubuntu server. I tried to use PHP (with appropriate lib installed) to connect to mongo to learn sth new. Unfortunaltey I cannot go any further. My user configuration looks like this:

> use testdb
switched to db testdb
> show users
{
    "_id" : "testdb.testdb",
    "user" : "testdb",
    "db" : "testdb",
    "roles" : [
        {
            "role" : "readWrite",
            "db" : "testdb"
        }
    ]
}

然后我尝试执行以下 PHP 代码:

Then I try to execute the following PHP code:

try{
    $uri = "mongodb://testdb:[e-mail]:27017/testdb";
    $options = array("connectTimeoutMS" => 30000);
    $client = new MongoClient($uri, $options );
}
catch(Exception $e) {
    echo 'Message: ' .$e->getMessage();
    die();
}
$db = $client->selectDB("testdb");

我收到消息:无法连接到:xxx.xxx.xxx.xxx:27017:用户名为testdb"的数据库testdb"上的身份验证失败:身份验证失败.

I get "Message: Failed to connect to: xxx.xxx.xxx.xxx:27017: Authentication failed on database 'testdb' with username 'testdb': auth failed".

在/etc/mongod.conf 中，我没有注释auth = true"

In /etc/mongod.conf I have "auth = true" uncommented

我还验证了这个conncetion:

I also verified the conncetion with:

> nc -w 3 -v xxx.xxx.xxx.xxx 27017 Connection to xxx.xxx.xxx.xxx 27017
> port [tcp/*] succeeded!

我通过互联网挖掘，我已经在这上面花了几个小时，我什至重新安装了 mongo 并重新设置了一切，但没有任何成功.你能指出在哪里寻找解决方案吗?

I dig through Internet, i spent few hours already on this, I even re-installed mongo and set everything up again without any success. Could you point to where to look for solution?

推荐答案

3.0 的身份验证架构与 2.x 驱动程序不兼容.您应该能够使其工作的一种方法是降级身份验证机制:

The authentication schema of 3.0 is not compatible with 2.x drivers. One way you should be able to make it work is by downgrading the authentication mechanism:

use "admin"
var schema = db.system.version.findOne({"_id" : "authSchema"})
schema.currentVersion = 3
db.system.version.save(schema)

然后创建一个用户，您应该能够与它连接.

Then create a user and you should be able to connect with it.
