Your MySQL server isn't running, has crashed, or doesn't create a sock file where you think it does. – tadman
sock file is exist on path ...but I am not able to start MySQL service.... when I going to start services its giving above error – krishna
Existing and being operational are two different things. Are you sure your process has permission to access it? Can you connect over IP instead? – tadman
No, I am not sure. If there is any way to check this ? And how I solved this Error ? – krishna

First you need to download xampp and ensure that my sql services on or off .if it is on then you are write function mysqli_connect(‘localhost’,’username’,’password’,’database’);

I guess you have a xampp installed in your system and SQL service was enabled. If yes, then create one database file in your application/config folder. Filename is database.php Here you need to give a default db driver variable, likewise

$db['default'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',
    'username' => 'your-db-username',
    'password' => 'your-db-password',
    'database' => 'your-db-name',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8mb4',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);

Next, you need to load this database.php config file in autoload.php (in the same directory).

$autoload['libraries'] = array('database');

Now, you have connected a database with your Codeigniter project.
