绿色版 MySQL 安装配置

一、下载MySQLhttp://www.mysql.org/downloads

我下载的是mysql-noinstall-5.0.67-win32.zip

二、安装过程1、解压缩 mysql-noinstall-5.0.67-win32.zip 到一个C盘，重新命名为 MySQL5 。 假定MYSQL_HOME=C:\ MySQL5

2、编辑mysql的运行配置文件my.ini，如果没有，可以拿my-medium.ini复制然后更名成 my.ini

代码如下:

# Example MySQL config file for medium systems. 
# 
# This is for a system with little memory (32M - 64M) where MySQL plays 
# an important part, or systems up to 128M where MySQL is used together with 
# other programs (such as a web server) 
# 
# 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 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 = 16M 
max_allowed_packet = 1M 
table_cache = 64 
sort_buffer_size = 512K 
net_buffer_length = 8K 
read_buffer_size = 256K 
read_rnd_buffer_size = 512K 
myisam_sort_buffer_size = 8M 

# 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 
skip-federated 

# 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 between 
# two methods : 
# 
# 1) Use the CHANGE MASTER TO command (fully described in our manual) - 
# the syntax is: 
# 
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>, 
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ; 
# 
# where you replace <host>, <user>, <password> by quoted strings and 
# <port> by the master's port number (3306 by default). 
# 
# Example: 
# 
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306, 
# MASTER_USER='joe', 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 to 
# 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 = <hostname> 
# 
# 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 to 
# 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 

# Point the following paths to different dedicated disks 
#tmpdir = /tmp/ 
#log-update = /path-to-dedicated-directory/hostname 

# Uncomment the following if you are using BDB tables 
#bdb_cache_size = 4M 
#bdb_max_lock = 10000 

# Uncomment the following if you are using InnoDB tables 
#innodb_data_home_dir = C:\mysql\data/ 
#innodb_data_file_path = ibdata1:10M:autoextend 
#innodb_log_group_home_dir = C:\mysql\data/ 
#innodb_log_arch_dir = C:\mysql\data/ 
# You can set .._buffer_pool_size up to 50 - 80 % 
# of RAM but beware of setting memory usage too high 
#innodb_buffer_pool_size = 16M 
#innodb_additional_mem_pool_size = 2M 
# Set .._log_file_size to 25 % of buffer pool size 
#innodb_log_file_size = 5M 
#innodb_log_buffer_size = 8M 
#innodb_flush_log_at_trx_commit = 1 
#innodb_lock_wait_timeout = 50 

[mysqldump] 
quick 
max_allowed_packet = 16M 

[mysql] 
no-auto-rehash 
# Remove the next comment character if you are not familiar with SQL 
#safe-updates 

[isamchk] 
key_buffer = 20M 
sort_buffer_size = 20M 
read_buffer = 2M 
write_buffer = 2M 

[myisamchk] 
key_buffer = 20M 
sort_buffer_size = 20M 
read_buffer = 2M 
write_buffer = 2M 

[mysqlhotcopy] 
interactive-timeout 

[mysqld]# 设置mysql的安装目录basedir=$MYSQL_HOME# 设置mysql数据库的数据的存放目录，必须是data，或者是\\xxx\datadatadir=$MYSQL_HOME\data# 设置mysql服务器的字符集default-character-set=utf8[client]# 设置mysql客户端的字符集default-character-set=gbk

3、安装mysql服务从MS-DOS窗口进入目录E:\myserver\mysql-5.0.37-win32\bin，运行如下命令：mysqld --install mysql --defaults-file=C:\MySQL5\my.ini

4、启动mysql数据库还在上面的命令窗口里面，输入命令：net start mysql这样就启动了mysql 服务。

5、停止服务执行 net stop mysql 即可

6、删除服务执行mysqld --remove mysql 即可

7、修改密码以上安装完毕之后，默认的root用户密码为空的。为了安全起见，需要设置一个root用户的密码。

代码如下:

<STRONG><SPAN style="COLOR: #ffffff" style="COLOR: #ffffff">C:\>cd MySQL5 

C:\MySQL5>cd bin 

C:\MySQL5\bin>mysql -uroot -p 
Enter password: 
Welcome to the MySQL monitor. Commands end with ; or \g. 
Your MySQL connection id is 3 
Server version: 5.0.67-community-log MySQL Community Edition (GPL) 

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
