php - Showing Error: mysqli::real_connect(): (28000/1045): Access denied for user 'user'@'192.188.145.163' (using password: YES) -

-

this codeigniter project. given database information right.it works in localhost. after uploading project in hosting site, still shows 'access denied' error.

this database:

 $db['default'] = array(     'dsn' => '',     'hostname' => 'telihatyhighschool.edu.bd',     'username' => 'db_username',     'password' => 'db_password',     'database' => 'db_name',     'dbdriver' => 'mysqli',     'dbprefix' => '',     'pconnect' => false,     'db_debug' => true,     'cache_on' => false,     'cachedir' => '',     'char_set' => 'utf8',     'dbcollat' => 'utf8_general_ci',     'swap_pre' => '',     'encrypt' => false,     'compress' => false,     'stricton' => false,     'failover' => array() ,     'save_queries' => true );

how can solve ?

in cpannel username , database name has cpanel username prefix eg

$active_group = 'default'; $active_record = true;  $db['default']['hostname'] = 'localhost'; //literaly put localhost $db['default']['username'] = 'cpanelusername_root'; $db['default']['password'] = 'password'; $db['default']['database'] = 'cpanelusername_db name'; $db['default']['dbdriver'] = 'mysqli'; ///use extension $db['default']['dbprefix'] = ''; $db['default']['pconnect'] = true; $db['default']['db_debug'] = true; $db['default']['cache_on'] = false; $db['default']['cachedir'] = ''; $db['default']['char_set'] = 'utf8'; $db['default']['dbcollat'] = 'utf8_general_ci'; $db['default']['swap_pre'] = ''; $db['default']['autoinit'] = true; $db['default']['stricton'] = false;

in more simple words

host = localhost (literally put localhost) database name = (cpanelusername_databasename) database username = (cpanelusername_databaseusername) database password = (******)

note: when connecting database, need ensure that:

  1. you've created database
  2. you've created database username
  3. you've assigned user privileges database

your mysql connections may use 127.0.0.1 or ip address of server, , mysql reject connection if access isn't granted specific ip address used.

verify permission tables (reloading grants if required) on server , you're connecting to

regrant preveliges :

grant privileges on *.* 'user'@'ip' identified '*userpass*';

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
