Install and configure green mysql

1. Download MySQL
Http://www.mysql.org/downloadsWhat I download is mysql-noinstall-5.0.67-win32.zip.Ii. Installation Process
1. Extract Mysql-noinstall-5.0.67-win32.zip To a drive C, rename it MySQL5 .
Assume thatMYSQL_HOME = C :\ MySQL5 2, edit mysql running configuration file my. ini, if not, you can copy the my-medium.ini and then name My. ini 
Copy codeThe Code is as follows:
# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32 M-64 M) where MySQL plays
# An important part, or systems up to 128 M where MySQL is used together
# Other programs (such as a web server)
#
# You can copy this file
#/Etc/my. cnf to set global options,
# Mysql-data-dir/my. cnf to set server-specific options (in this
# Installation this directory is C: \ 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

# Here follows entries for some specific programs

# The MySQL server
[Mysqld]
Basedir = "C: \ MySQL5"
Datadir = "C: \ MySQL5 \ data"
Default-character-set = utf8

Port = 3306
Socket =/tmp/mysql. sock
Skip-locking
Key_buffer = 16 M
Max_allowed_packet = 1 M
Table_cache = 64
Sort_buffer_size = 512 K
Net_buffer_length = 8 K
Read_buffer_size = 256 K
Read_rnd_buffer_size = 512 K
Myisam_sort_buffer_size = 8 M

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# If all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (Via the "enable-named-pipe" option) will render mysqld useless!

# Skip-networking

# Disable Federated by default

# Replication Master Server (default)
# Binary logging is required for replication
Log-bin = mysql-bin

# Required unique id between 1 and 2 ^ 32-1
# Defaults to 1 if master-host is not set
# But will not function as a master if omitted
Server-id = 1

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose
# Two methods:
#
#1) Use the change master to command (fully described in our manual )-
# The syntax is:
#
# Change master to MASTER_HOST = # MASTER_USER = <user>, MASTER_PASSWORD = <password>;
#
# Where you replace # <Port> by the master's port number (3306 by default ).
#
# Example:
#
# Change master to MASTER_HOST = '192. 564.12.1 ', MASTER_PORT = 125,
# MASTER_USER = 'job', MASTER_PASSWORD = 'secret ';
#
# OR
#
#2) Set the variables below. However, in case you choose this method, then
# Start replication for the first time (even unsuccessfully, for example
# If you mistyped the password in master-password and the slave fails
# Connect), the slave will create a master.info file, and any later
# Change in this file to the variables 'values below will be ignored and
# Overridden by the content of the master.info file, unless you shutdown
# The slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (Commented) and instead use change master to (see above)
#
# Required unique id between 2 and 2 ^ 32-1
# (And different from the master)
# Defaults to 2 if master-host is set
# But will not function as a slave if omitted
# Server-id = 2
#
# The replication master for this slave-required
# Master-host = #
# The username the slave will use for authentication when connecting
# To the master-required
# Master-user = <username>
#
# The password the slave will authenticate with when connecting
# The master-required
# Master-password = <password>
#
# The port the master is listening on.
# Optional-defaults to 3306
# Master-port = <port>
#
# Binary logging-not required for slaves, but recommended
# Log-bin = mysql-bin

3. Install the mysql Service
Enter the directory E: \ myserver \ MS-DOS \ bin from the mysql-5.0.37-win32 window and run the following command:
Mysqld -- install mysql -- defaults-file = C: \ MySQL5 \ my. ini
4. Start the mysql database
In the above command window, enter the command: net start mysql
In this way, the mysql service is started.
5. Stop the service
Execute net stop mysql. 6. Delete the service.
Execute mysqld -- remove mysql.
7. Change the password
After the above installation is complete, the default root user password is blank. To ensure security, you need to set a password for the root user.Copy codeThe Code is as follows:
<STRONG> <SPAN style = "COLOR: # ffffff" style = "COLOR: # ffffff"> C: \> cd MySQL5

C: \ MySQL5> cd bin

C: \ MySQL5 \ bin> mysql-uroot-p
Enter password:
