绿色版 mysql 安装配置

一、下载MySQL
http://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 
 

# 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=$MYSQL_HOME
# 设置mysql数据库的数据的存放目录,必须是data,或者是\\xxx\data
datadir=$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。
 

<STRONG><SPAN >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.  

mysql> use mysql  
Database changed  
mysql> update User set Password=PASSWORD('admin') where User='root';  
Query OK, 2 rows affected (0.08 sec)  
Rows matched: 2  Changed: 2  Warnings: 0</SPAN> 

</STRONG>
