Solution:

Just reinitialize the database

Shell > / usr/local/mysql/scripts/mysql_install_db-user=mysql-basedir=/usr/local/mysql-datadir=/usr/local/mysql/ data`

After that, the database starts successfully

Shell > / etc/init.d/mysqld start

Starting MySQL. SUCCESS!

Set the login password for root users:

Shell > mysqladmin-uroot-p password '123456'

Enter password: [default password is empty and you can enter directly]

Warning: Using a password on the command line interface can be insecur
