Unable to connect to your database server using the provided settings.
I’ve been having difficulty connecting my application to my remote database. I’m receiving the error shown above when I run my application. I’ve looked at previous answers to this question on this site, but I’ve gotten no luck at solving it. From what I learnt, I need to replace the hostname and make my mysql database accept external connections, which I have both done. I tried the same values in my database.php through the mysql command-line and it works.
So what else could I possibly be missing?
Here are my settings in database.php:
$active_group = 'staging';
$active_record = TRUE;
$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'root';
$db['default']['password'] = '';
$db['default']['database'] = 'myDatabase';
$db['default']['dbdriver'] = 'mysql';
$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;
$db['staging']['hostname'] = 'XX.XX.XXX.XXX';
$db['staging']['username'] = 'user';
$db['staging']['password'] = 'pwd';
$db['staging']['database'] = 'myDatabase';
$db['staging']['dbdriver'] = 'mysql';
$db['staging']['dbprefix'] = '';
$db['staging']['pconnect'] = TRUE;
$db['staging']['db_debug'] = TRUE;
$db['staging']['cache_on'] = FALSE;
$db['staging']['cachedir'] = '';
$db['staging']['char_set'] = 'utf8';
$db['staging']['dbcollat'] = 'utf8_general_ci';
$db['staging']['swap_pre'] = '';
$db['staging']['autoinit'] = TRUE;
$db['staging']['stricton'] = FALSE;
try this command from your shell to see if you can connect:
also check to see if you don’t have a different port to connect to mysql set, by default codeigniter will connect to 3306, unless you define the actual port set. this might be the issue.
good luck
