I am using mysqldb (the python MySQL) module.. But everytime I try to run. it gives me this error.
super(Connection, self).__init__(*args, **kwargs2)
_mysql_exceptions.OperationalError: (2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)")
I think the issue is multiple mysql installed.. but I am no mysql expert.. actually besides python.. assume i have a very minimal knowledge of OS.. mysql.or any other thing, :)
I have also installed XAMPP on ubuntu.. and everytime i start the xampp module But before I start the xampp server.. I always do the following..
sudo /etc/init.d/mysql stop (this is my clue that there is another mysql installed :D )
To start the XAMPP local host I do the following
sudo /opt/lampp/lampp start
And the error says
_mysql_exceptions.OperationalError: (2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)")
I am elaborating on all of the above just to demonstrate where the paths of what is relevant to solve this thing lives.. Can you please help me out. Thanks.

Aaghh a stupid overlooking of facts on my part.. In the question I did said that I am stopping the default mysql.. before starting the xampp mysql.. but forgot to restart it.. and unfortunately
/etc/init.d/mysql start
wont work you have to do
/etc/init.d/mysql restart
其他提示
Apparently XAMPP has it's socket in a different place, so you need to explicity say where the socket is, since it's not at /var/run/mysqld/mysqld.sock. This will be something like:
kwargs2['unix_socket'] = '/some/other/path/mysqld.sock'
super(Connection, self).__init__(*args, **kwargs2)
You might find the socket with the command:
find /opt/lampp -name "*.sock"
