MySQL class to add user/database

I'm creating tool to add new virtualhost on UNIX-box. One of tasks is to add a new user and database to MariaDB (aka MySQL) server. In fact - this my first 'real' attempt to use OOP.

Here is class, which I created for it:

class mysqlUserDb:
        warnings.filterwarnings('error')
        def __init__(self):
                self.root = 'root'
                self.host = 'localhost'
                self.rootpw = 'p@ss'

                try:
                        print '\nChecking MySQL connection...'
                        self.db = MySQLdb.connect(self.host, self.root, self.rootpw)
                        self.cursor = self.db.cursor()
                        self.cursor.execute('select version()')
                        print 'Connection OK, proceeding.'
                except MySQLdb.Error as error:
                        print 'Error: %s ' %error + '\nStop.\n'
                        sys.exit()

        def createdb(self, db):
                print '\nCreating database...'
                try:
                        self.cursor.execute('create database if not exists ' + db)
                        self.cursor.execute('show databases like ' + '\'' + db + '\'')
                        dbs = self.cursor.fetchone()
                        print 'Database created: %s' %dbs
                except Warning as warn:
                        print 'Warning: %s ' %warn  + '\nStop.\n'
                        sys.exit()

        def grants(self, user, userpass, db):
                print '\nGrant privilegies... '
                try:
                        self.cursor.execute('grant all on ' + db + '.*' + 'to ' + '\'' + user + '\'' + "@'localhost'" + 'identified by ' + '\'' + userpass + '\'')
                        self.cursor.execute('select user, db from mysql.db where db=' + '\'' + db + '\'')
                        grs = self.cursor.fetchall()
                        print 'Access granted: %r' %grs
                except Warning as warn:
                        print 'Warning: %s ' %warn  + '\nStop.\n'
                        sys.exit()
                except MySQLdb.Error as error:
                        print 'Error: %s ' %error + '\nStop.\n'
                        sys.exit()

        def __del__(self):
                print '\nFinishing operations...'
                self.cursor.close()
                self.db.close()
                print 'Done.\n'

Next, in tool it call like:

import createvhostFunctsClass as fun

mysql = fun.mysqlUserDb()
mysql.createdb('db_2')
mysql.grants('user', 'pass', 'db_2')
del mysql

(it's just example, not included yet in tool).

And its works like:

$ ./myclass.py

Checking MySQL cconnection...
Connection OK, proceeding.

Creating database...
Database created: db_2

Grant privilegies...
Access granted: ('user', 'db_2')

Finishing operations...
Done.

I'm pretty sure, here is lot of stuff, which I missed or did incorrectly (or not the "Python way").

Also, I'm not sure - which way better:

1. create methods for each action (add database, add user) and just call this methods from script (currently done)
2. create one method, which will get needed action ('create database lalala') as argument and call this method several times in script
