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

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

Two main reasons:

1) mysql-server isn't installed! You have to install it (mysql-server and not mysql-client) and run it.

2) It's installed by default and running. So, it's not possible to run it again through Xampp or Lampp. You have to stop it: sudo service mysql stop

then you can start it through Xampp. It's possible to check if it's running or not with this code: sudo netstat -tap | grep mysql

If you see a result like this: tcp 0 0 localhost:mysql : LISTEN 1043/mysqld

It means that it's running properly.

Answer 2

The client should be set consistent with server setting.

[client]
port        = 3306
socket      = /var/run/mysqld/mysqld.sock

[mysqld]
user        = mysql
pid-file    = /var/run/mysqld/mysqld.pid
socket      = /var/run/mysqld/mysqld.sock
port        = 3306

Answer 3

In the linux terminal, I run the following steps and they helped me out

1.First of all list all the mysql packages installed

  sudo dpkg -l | grep mysql

2.Delete the listed packages with the listed command

  sudo apt-get --purge autoremove <package name>

3.Reinstall mysql server

  sudo apt-get install mysql-server

This worked for me, Hope this works for you aswell.

Alternatively Try

sudo apt-get remove --purge mysql-\

then reinstall with

sudo apt-get install mysql-server mysql-client

Answer 4

I also met this problem. mysql -u root -p Enter password: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)

Then I find the reason is my selinux is enforcing, I disable it then restart mysqld , it works, hope helpful.

Answer 5

This took me ages to figure out but could you try the same -

1 - Update and Upgrade

sudo apt-get update
sudo apt-get upgrade

2 - Purge MySQL Server and Client (if installed).

sudo apt-get purge mysql-server mysql-client

3 - Install MySQL Server and Client fresh

sudo apt-get install mysql-server mysql-client

4 - Test MySQL

mysql -u root -p
> enter root password

*** should get socket not found in /var/run/mysqld/mysql.sock

4 - Configure mysqld.cnf with nano of vi

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

Change bind-address from 127.0.0.1 to localhost

bind-address            = localhost

** Write and Exit

5 - Restart MySQL

sudo /etc/init.d/mysql restart

6 - check mysql

mysql -u root -p
> enter root password
