解决PHP使用普通账号连接mongodb报错问题

 

起先使用mongodb来开发,未加上账号密码验证功能. mongodb一直正常,准备放到线上之时加上账号密码功能,整个过程如下:

mongo配置

  1. 增加mongodb账号
  2. 增加用户a_ttlsa_com对a_ttlsa_com这个库有读写权限,密码为ttlsa.com.passwd
# mongo
 MongoDB shell version: 2.4.5
 connecting to: test
 > use a_ttlsa_com
 switched to db a _ttlsa_com
 > db.addUser("a_ttlsa_com","ttlsa.com.passwd")
 {
 "user" : "a_ttlsa_com",
 "readOnly" : false,
 "pwd" : "48f7704260bf8c966fcdec40915f5c22",
 "_id" : ObjectId("52327181611f841827ccae9d")
 }

php配置

我这边是yii框架,连接方式大同小异

    "mongodb" => array(
        "class"            => "EMongoDB",
        "connectionString" => "mongodb://a_ttlsa_com:ttlsa.com.passwd@192.168.50.101",
        "dbName"           => "a_ttlsa_com",
        "fsyncFlag"        => true,
        "safeFlag"         => true,
        "useCursor"        => false
    ),

打开页面,出现如下报错:

    EMongoDB failed to open connection: Failed to connect to: 192.168.50.101:27017:Authentication failed on database "admin" with username "a_ttlsa_com": auth fails

用户密码密码都是正确,为什么会去连接admin数据库,是不是有点莫名其妙,其实这边犯了一个错误。mongodb的连接字符串后面要加上库名,否则他默认会去连接admin库,所以配置文件后面的dbName实际上和连接完全没有关系.

配置文件修改为如下:

    "mongodb" => array(
        "class"            => "EMongoDB",
        "connectionString" => "mongodb://a_ttlsa_com:ttlsa.com.passwd@192.168.50.101/a_ttlsa_com",
        "dbName"           => "a_ttlsa_com",
        "fsyncFlag"        => true,
        "safeFlag"         => true,
        "useCursor"        => false
    ),

恢复正常.
