I am using CodeIgniter and I am trying to access a database that is placed remotely on another server. I can access that server remotely but I can't connect via my MySQL Connection settings. Here are my MySQL settings:
$db['default']['hostname'] = 'myhostname';
$db['default']['username'] = 'root';
$db['default']['password'] = '';
$db['default']['database'] = 'MyDb';
$db['default']['dbdriver'] = 'mysqli';
$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;
I am not sure where I am making a mistake so if someone can point out the mistake it will be really helpful.
First, check username and password for mysql (obviously username cannot be root and password cannot be blank for security reasons) and for hostname, you might have to supply IP address of your server where mysql is hosted. Rest configurations appear to be fine. You can ask for these information from your hosting company.

I am using Postgresql database connection with codeigniter. I am new to postgresql. The site opens. But I cannot login nor fetch any values from the database.
I will upload the code for my config file as well as the database.php file.
config.php
// Keep as it is for same if MySQL server is running on same server
define("DBHOSTNAME",'ip_address');
// Add your database name here
define("DBNAME",'db_name'); // Here the database name is 'dummy_myecommerce'
// Add your database user name here
define("DBUSER",'username'); // Here the username is 'dummy_website'
// Add your database password here
define("DBPWD",'password');
Now I will upload the database.php file:
$db['default']['hostname'] = 'ip_address';
$db['default']['username'] = 'username';
$db['default']['password'] = 'password';
$db['default']['database'] = 'db_name';
$db['default']['dbdriver'] = 'postgre';
$db['default']['dbprefix'] = 'pre_';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = FALSE;
$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['default']['port'] = 5432;
If anything else is required, please let me know. Thanks
Some database drivers (such as PDO, PostgreSQL, Oracle, ODBC) might require a full DSN string to be provided. If that is the case, you should use the ‘dsn’ configuration setting, as if you’re using the driver’s underlying native PHP extension, like this:
// PDO
$db['default']['dsn'] = 'pgsql:host=localhost;port=5432;dbname=database_name';
Helpful link - http://www.codeigniter.com/user_guide/database/configuration.html
Try this as well
$db['default']['hostname'] = 'pgsql:host=localhost;dbname=yourdb'; //set host
$db['default']['username'] = 'your username'; //set username
$db['default']['password'] = 'your password'; //set password
$db['default']['database'] = 'your database'; //set databse
$db['default']['dbdriver'] = 'pdo'; //set driver here
I have a remote mysql server. Now I am developing a software in Codeigniter integrated with that mysql server. I gave the GRANT ALL to 'user'#'myid' in mysql user. But codeigniter shows the following error:
A Database Error Occurred
Unable to connect to your database server using the provided settings.
How can i use remote mysql in my local development environment?
BTW: I use WAMP in windown 7.
Thanks in advance.
EDIT:
Database Configuration:
$db['default']['hostname'] = '198.xxx.xx.66';

I'm developing a website application using codeigniter at localhost and then i host it in hawkhost.
At localhost it runs well, but at host there's and error :
Unable to connect to your database server using the provided settings.
Filename: core/Loader.php Line Number: 346
this is my db configuration
$active_group = 'default';
$active_record = TRUE;
$db['default']['hostname'] = 'localhost';
$db['default']['username'] = '****';
$db['default']['password'] = '****';
$db['default']['database'] = '****';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE;
$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;
I know many people already asked this problem but it doesn't seems to solve anything on my case.
changing $db['default']['db_debug'] = TRUE; to false only hide the error but when i tried to get data from query it doesn't return anything.
I also tried to change $db['default']['pconnect'] = FALSE; to true and still doesn't work.
Any help please?
Just change localhost to the local ipaddress i.e. 127.0.0.1 and it will start working.
$db['default']['hostname'] = 'localhost';
to
$db['default']['hostname'] = '127.0.0.1';
In my case setting pconnect to false worked.
$db['default']['pconnect'] = FALSE;
The problem is really due to credentials.
I test it using simple code to check if connection can be made.
The problem is in username, i realize there's additional suffix when using hosting. such as suffix_user
I think the same errors in Core/Loader.php Line Number: 346 has the same solution. make sure the username, password and host are right.
It's solved. Thank you everyone for helping.
Just change
$db['default']['hostname'] = 'localhost';
to
$db['default']['hostname'] = '127.0.0.1';
and voila.
Most of the time this problem happens when codeigniter is in live environment.
That’s why I assumed a domain name ‘(example: domainname.com)’ and after creating a mysql database (example: testDb) and user name (example: testUser) you will find a prefix name automatically added with your mysql database name and user name like ‘domainname_ testDb’ and ‘domainname_ testUser’.
Now in codeigniter /application/config/database.php edit following:
$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'domainname_ testDb ';
$db['default']['password'] = '*******';
$db['default']['database'] = 'domainname_ testUser';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE;
$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['default']['hostname'] = 'localhost';
$db['default']['username'] = 'domainname_ testDb ';
$db['default']['password'] = '*******';
$db['default']['database'] = 'domainname_ testUser';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE;
$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;
If anyone else is having this issue, try disabling SE-Linux if you have it enabled. It was causing the connection issues for me, with php 5.4.
Also worth checking is switching
$db['default']['dbdriver'] = 'mysql';
to
$db['default']['dbdriver'] = 'mysqli';
as mysql is depreciated after php 5.5.
I have searched the net to no solution for a problem I am facing.
I am working on a codeigniter project which I am running on a localhost Apache Server. For the database, I am attempting to connect from CI's database.php configuration file to connect to a remote server.
The following is my configuration
$active_group = 'default';
$active_record = TRUE;
$db['default']['hostname'] = 'remotedatabase.com';
$db['default']['username'] = 'remote_2102Dev';
$db['default']['password'] = '1q2w3e4r5t';
$db['default']['database'] = 'remote_cs2102';
$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;
I have tried to connect to the remote Database via mysql workbench 5.5. So that means I have did the configuration correctly at the server side.
Please help me. Is this CI problem or there is something wrong with my settings. Thank you.
Check host entry # remotedatabase.com. It should be % in host
If your PHP version is >= 5.3 set db_debug to false:
$db['default']['db_debug'] = FALSE;
I have never worked with DB2 before. I am trying to connect from codeigniter. I have used the following settings in my database config file:
$db['default']['hostname'] = 'ipAddress';
$db['default']['port'] = 'portNumber';
$db['default']['username'] = 'uname';
$db['default']['password'] = 'pword';
$db['default']['database'] = 'myDBName';
//$db['default']['dbdriver'] = 'pdo';
$db['default']['dbdriver'] = 'odbc';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE;
$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;
and it throws the following error:
Unable to connect to your database server using the provided settings.
Filename: C:\xampp\htdocs\archive\system\database\DB_driver.php
Again, I am totally new to DB2, so in case I need to install anything extra (I assume the driver is already included in my latest CI download) or I need to define a dsn (please let me know how to do that if i require that) please do let me know, will very much appreciate your help.
Yes, you need to install the IBM Data Server Client package, or at least Runtime Client. Download the appropriate driver from http://www-01.ibm.com/support/docview.wss?uid=swg27016878
The manual explains how to configure DB2 access from a PHP application.
You need to add the full connection to the hostname parameter , as the following code
$active_group = 'default';
$active_record = FALSE;
$db['default']['hostname'] = "driver={IBM db2 odbc DRIVER};Database=DBNAME;hostname=localhost;port=50000;protocol=TCPIP;" . "uid=username; pwd=password";
$db['default']['username'] = 'username';
$db['default']['password'] = 'password';
$db['default']['database'] = 'DBNAME.SCHEMANAME';
$db['default']['dbdriver'] = 'odbc';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = FALSE;
$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;
