Assuming you know your current 'root' passwords, to reset your system's 'root' password you need to login to your server via ssh and execute

# passwd

it will ask you to enter and confirm your new system's 'root' password.

as for resetting the mysql's 'root' password, you need to login to your mysql server as root by executing:

# mysql -u root -p

once you're in, you need to change the database to 'mysql'

mysql> use mysql;

and then reset your mysql's 'root' password by executing:

mysql> update user set Password=PASSWORD('YOUR_NEW_PASS') WHERE User='root';

to quit the mysql shell type:

mysql> \q

cheers

I'm not that familiar with ISPConfig 3 and cannot tell for sure if it or its services use a MySQL database, specifically the 'root' account.

You may want to wait for an answer on this from some one who knows how things work in ISPConfig 3.

anyhow, the services like apache, bind, dovecot, postfix should not be affected by the change of your mysql 'root' password.

Thank you rosehosting. I am waiting for someone who knows the answer...

ISPConfig uses the mysql root password only to create new databases, all other operations are donw ith the less priveliged mysql user "ispconfig". So after you changed the mysql root password change it in the file /usr/local/ispconfig/server/lib/mysql_clientdb.conf as well.
