[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.

Answer 1

registered there password=root

This should not be a password, but a login.
Like this:

user=root
password=BigSecret

After (re)starting the server, you need to make sure that the server is ready to accept connections.
If specified in a configuration like this, socket=/var/mysql/mysql.sockthen check with mysqladmin -u root -p status.
If the connection is through a network port, then you need to check the ports listening like this: netstat -tuln4(Linux / Mac)
Try to check the connection withmysqladmin -h 127.0.0.1 -P 3306 -u root -p status
