You can establish MySQL database using mysql binary at command prompt.
Here is a simple example to connect to MySQL server from command prompt:
[root@host]# mysql -u root -p
This will give you mysql> command prompt where you will be able to execute any SQL command.
Following is the result of above command:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2854760 to server version: 5.0.9
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
In above example we have used root as a user but you can use any other user. Any user will
be able to perform all the SQL operation which are allowed to that user.
You can disconnect from MySQL database any time using exit command at mysql> prompt.
PHP provides mysql_connect() function to open a database connection. This function takes
five parameters and returns a MySQL link identifier on success, or FALSE on failure.
You can disconnect from MySQL database anytime using another PHP function mysql_close().
This function takes a single parameter which is a connection returned by mysql_connect()
bool mysql_close ( resource $link_identifier );
If a resource is not specified then last opened database is closed. This function returns true if
it closes connection successfully otherwise it returns false.
Try out following example to connect to a MySQL server:
<title>Connecting MySQL Server</title>
$dbhost = 'localhost:3036';
$dbuser = 'guest';
$dbpass = 'guestpass';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
die('Could not connect: ' . mysql_error());
echo 'Connected successfully';
