前言
大家在Mongodb安装好后,一般不需要用户名密码就可以直接使用,开发者认为只要使用环境足够安全,可以不使用认证,但是在实际使用中为了数据的安全,大多人还是选择了开启权限认证。
一、在老版的Mongodb(大概3.0以前)可以这样开启认证:
1、Linux环境下mongo shell方式认证:

>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

}
##之后运行
>showdbs

添加--auth 启动

switched to db admin
> db.auth('admin','12345678') ##用添加的账户密码查看

<?php
##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>" ;
}

二、在3.0版之后的Mongodb,shell中依旧可以使用上述方法验证,但是php认证一直失败,日志中会报错( Failed to authenticate myuser@userdb with mechanism MONGODB-CR: AuthenticationFailed MONGODB-CR credentials missing in the user document
),原来新版的mongodb加入了SCRAM-SHA-1校验方式,需要第三方工具配合进行验证。
下面给出具体解决办法:
首先关闭认证,修改system.version文档里面的authSchema版本为3,初始安装时候应该是5,命令行如下:
1

3

|
> 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 })
|
不过如果你现在开启认证,仍然会提示AuthenticationFailed MONGODB-CR credentials missing in the user document
原因是原来创建的用户已经使用了SCRAM-SHA-1认证方式

> use admin
> db.auth('root','123456')
> db.system.users.find()
{ "_id" : "admin.root", "user" : "root", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "XoI5LXvuqvxhlmuY6qkJIw==", "storedKey" : "VAT7ZVMw2kFDepQQ6/E0ZGA5UgM=", "serverKey" : "TebHOXdmY6IHzEE1rW1Onwowuy8=" } }, "roles" : [ { "role" : "userAdminAnyDatabase", "db" : "admin" } ] }
{ "_id" : "mydb.test", "user" : "test", "db" : "mydb", "credentials" : { "MONGODB-CR" : "c8ef9e7ab00406e84cfa807ec082f59e" }, "roles" : [ { "role" : "readWrite", "db" : "mydb" } ] }
|
解决方式就是删除刚刚创建的用户,重新重建即可:
1

3
|
> db.system.users.remove({user:"test"});
> use mydb
>db.createUser({user:'test',pwd:'123456',roles:[{role:'readWrite',db:'mydb'}]})
|
然后开启认证,重启服务器,用php连接,一切OK
