Below is the process to reset the root user password, when we forgot the root user password or missed to recollect the password provided during installation.

OS - Ubuntu 16.04

MySQL - 5.7

1. Stop Mysql Server sudo /etc/init.d/mysql stop
2. To avoid the error, mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists , run below commands: sudo mkdir -p /var/run/mysqld sudo chown mysql:mysql /var/run/mysqld
3. Start mysql in safe mode: sudo mysqld_safe --skip-grant-tables &
4. Login to Mysql and change the password to say 'root123': In 5.7 version the password column is renamed as authentication_string. mysql -uroot mysql>use mysql; mysql>update user set authentication_string=password('root123') where user='root';
5. If you get the error :: MySQL fails on: mysql “ERROR 1524 (HY000): Plugin 'auth_socket' is not loaded” then run below commands and then run 4th Step. mysql>update user set plugin="mysql_native_password" where User='root'; mysql>flush privileges; quit;
