How to install MySQ Server 6.0 in Ubuntu 10.04 LTS Desktop?

(All commands need root user privilege of Ubuntu)
1. Download "mysql-6.0.11-alpha-linux-i686-glibc23.tar.gz" from MySQL website.

2. tar -zxvf mysql-6.0.11-alpha-linux-i686-glibc23.tar.gz

3. Rename it: mv mysql-6.0.11-alpha-linux-i686-glibc23.tar.gz mysql

4. Copy mysql folder to "/usr/local/mysql": cp -r mysql /usr/local/mysql

5. Change mode of mysql: chmod -R 777 mysql

6. Copy "my-small.cnf" to "/etc/my.cnf":

     # cd /usr/local/mysql/support-files
     # cp my-small.cnf /etc/my.cnf

7. Configure my.cnf (Red font text is updated; Green is added):

# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /usr/local/mysql/data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients
[client]
#password = your_password
port = 3306
socket = /tmp/mysql.sock   (Update it to this sock file if its position is changed.
Actually you need find this file - find / -name mysql.sock, and put down its name here.)
No bind-address to have remote client (MySQL-Front) access this MySQL server
# Here follows entries for some specific programs
# The MySQL server
[mysqld]
user=root     [color=gray]Add root user)
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data[/color]
port = 3306
socket = /tmp/mysql.sock     Update it to this sock file if its position is changed.)

# (using the "enable-named-pipe" option) will render mysqld useless!
