Question

I\'m getting this error

ERROR 2002 (HY000): Can\'t connect to local MySQL server through socket \'/var/run/mysqld/mysql.sock\' (2)

even though

Answer 1

The same error occured with my system as well. I had to remove mysql-server and reinstall it. Not other way around. Try running these commands it it works:

1. sudo apt-get purge mysql-server
2. sudo apt-get autoremove
3. sudo apt-get install mysql-server

Answer 2

My problem was solved checking if the process was running on Ubuntu 12.04

ps ax | grep mysql

Then the answer was that it wasn't running, so I did

sudo service mysql start

Or try

sudo /etc/init.d/mysql start

Answer 3

If you look close, you'll see the difference:

• The server listens on /var/run/mysqld/mysqld.sock
• The client tries to connect to /var/run/mysqld/mysql.sock

You'll have to adjust the one or the other.

Answer 4

this worked for me

sudo /etc/init.d/mysql start

first i tried this, but i dont understand why it doesn't work this way

sudo service mysql start

Answer 5

I had the problem.

This process worked for me:

Ensure that during remove process you choose No to deleting database.

sudo apt-get remove --purge mysql*

sudo apt-get autoremove

sudo apt-get autoclean

sudo apt-get install mysql-server mysql-client

Answer 6

Note that I ran into this trouble after I upgraded my Ubuntu 14.04 distribution using apt-get upgrade. I had to completely purge mysql-server and mysql-client and reinstall it to fix this issue.

sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get purge mysql-server mysql-client
sudo apt-get install mysql-server mysql-client

Hope this helps.
