I am trying to connect to mysql server in ubuntu 12.04 from terminal using and password empty("")
mysql -u root -p
it throwing error
ERROR 2002 (HY000): Can't connect to mysql server through socket 'var/run/mysql/mysqld.sock'(2)
Though i am able to access database successfully from phpmyadmin and there i see there is no password for root in user user table in mysql database.
I am using xampp package
回答1:
I think the error is the socket file. Where did you install your xampp?
Can you try this,
mysql -u root -p --socket=/opt/xampp/var/mysql/mysql.sock
where opt is your installation directory. Change opt to your installation directory.
edit: Or if you don't want using socket parameter on your mysql command, you can try
ln -s /opt/xampp/var/mysql/mysql.sock /var/run/mysql/mysqld.sock
Thanks.

what i can guess about your problem:following
If your file my.cnf (usually in the /etc/mysql/ folder) is correctly configured with
socket=/var/lib/mysql/mysql.sock
you can check if mysql is running with the following command:
mysqladmin -u root -p status
try changing your permission to mysql folder. If you are working locally, you can try:
sudo chmod -R 755 /var/lib/mysql/
that solved it for me
