#1045 Cannot log in to the MySQL server

Question

I am trying to setup LAMP on my OS, so I have installed apache, php, mysql using the following commands:

sudo apt-get install apache2
sudo apt-get install php5
sudo apt-get install libapache2-mod-php5
sudo apt-get install mysql-server libapache2-mod-auth-mysql php5-mysql
sudo apt-get install phpmyadmin

Everything works fine except that I cannot log into MySQL (which leads to phpmyadmin failure login). I'm getting the errors:

#1045 Cannot log in to the MySQL server
Access denied for user 'root'@'localhost' (using password: YES)

I googled the problem and I have also tried to reinstall all installed components, but the same result came up!

On Windows, I usually modified the content of mysql configuration file, but in Ubuntu nothing is the same as Windows!

Solution

I think that you should reset the password of root user.

How to reset MySQL root password.

To reset your mysql password of root user, just follow these instructions.

Step1. Stop the mysql demon process using this command :

sudo service mysql stop

Step2. Start the mysqld demon process using the --skip-grant-tables option with this command:

sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking &

Step3. Start the mysql client process using this command:

mysql -u root

Step4. From the mysql prompt execute this command to be able to change any password:

FLUSH PRIVILEGES;

Step5. Then reset/update your password and quit:

SET PASSWORD FOR root@'localhost' = PASSWORD('password');
quit

Step6. Start the mysql demon process using this command :

sudo service mysql start

Now, you can log in to MySQL as root user.

thanks, that worked well and also found something else that in my re-installation i typed sudo apt-get remove mysql-server which removed mysql-server but keeps the config files so in my next installation it loads the last one's config files so the result would be the same! i just should type apt-get --purge mysql-server instead :)

After Step3 i get error "ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) [1]+ Exit 1 sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking " on Ubuntu 16.04
