Installing MySQL on Solaris (Part 2 - Changing Passwords)

Change the Passwords

Don’t forget to change the passwords for the root and unknown users:

/opt/mysql/mysql/bin/mysqladmin -u root password 'new-password'

/opt/mysql/mysql/bin/mysqladmin -u root -h unknown password 'new-password'

Alternatively you can run:

/opt/mysql/mysql/bin/mysql_secure_installation

which will also give you the option of removing the test databases and anonymous user created by default.  This is strongly recommended for production servers.
