mysql 5.7 fix root user

posted on 2016-08-22 13:42

In mysql 5.7 the auth mechanism changed, documentation can be found in the official manual here.

Using the system root user (or sudo) you can connect to the mysql database with the mysql 'root' user via CLI. All other users will work, too.

In phpmyadmin, for example, however, all mysql users will work, but not the mysql 'root' user.

This comes from here:

$ mysql -Ne "select Host,User,plugin from mysql.user where user='root';"

+-----------+------+-----------------------+
| localhost | root | auth_socket           |
|  hostname | root | mysql_native_password |
+-----------+------+-----------------------+

To 'fix' this security feature, do:

mysql -Ne "update mysql.user set plugin='mysql_native_password' where User='root' and Host='localhost'; flush privileges;"

More on this can also be found here in the manual.

mysql 5.7 reset root password

posted on 2016-08-04 14:04

Resetting the mysql root password changed with version 5.7, along with quite some other stuff.

If you have further trouble logging in with the local root account itself, these steps should fix all the problems.

  • stop mysql server (service mysql stop or ps aux | grep mysql to determine the PID and then kill -9 PID)
  • mysqld_safe --skip-grant-tables
  • mysql -Ne "UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE User = 'root';" to fix the root PW not working
  • mysql -Ne "UPDATE mysql.user SET authentication_string=password('YOURNEWPASSWORD') WHERE user='root';"
  • killall -9 mysqld_safe
  • service mysql start
