2016-04-25 23:25:16 -0500 answered a question How change password mysql

I am not sure if this will work, but as the mariadb server gave error (using password: NO) you must first enter the root user and create a password for the same.

$ MySQL -u root

This shouldn't ask for password but if it does try leaving it blank. You should be into the root MySQL user


Try the following commands to change password:

update user set password=PASSWORD("NEWPASSWORD") where User='root';

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass');

Note: 'MyNewPass' should be your password in plain text.

Is direct upgrade from Juno to Mitaka possible? What documentations should be referred for that?

2016-04-25 12:15:24 -0500 asked a question How to manage huge backups before upgrade?

I want to know the recommended method to manage backups before upgrade to next release. Is it required to allocate additional storage space for backups prior to upgrade? Or just the regular backups are enough? Which doc to be referred for backup and backup restore?
