This is done (after starting database) with:
/usr/bin/mysqladmin -h $hostname -u mysql password 'password'
/usr/bin/mysqladmin -u mysql_logrotate password 'password'
-NOTE: mysql_logrotate password should be placed to /etc/mysqld.conf in
+NOTE: mysql_logrotate password should be placed to $MYSQL_CONFIG in
mysqladmin section. See the manual for more instructions.
+NOTE: if you are using cluster ability of this package you need
+to specify different socket for each cluster (see --socket option)
