windows 7 64位下配置mysql64位免安装版

1、官方网站下载mysql-noinstall-5.1.51-winx64.zip

2、解压到E:\Program Files\MySQL.（路径自己指定）

3、在E:\Program Files\MySQL下新建my.ini配置文件，内容如下：

# MySQL Server Instance Configuration File

# ----------------------------------------------------------------------

# Generated by the MySQL Server Instance Configuration Wizard

#

#

# Installation Instructions

# ----------------------------------------------------------------------

#

#

# CLIENT SECTION

# ----------------------------------------------------------------------

#

# The following options will be read by MySQL client applications.

# Note that only client applications shipped by MySQL are guaranteed

# to read this section. If you want your own MySQL client program to

# honor these values, you need to specify it as an option during the

# MySQL client library initialization.

#

[client]





port=3306





[mysql]





default-character-set=gbk





# SERVER SECTION

# ----------------------------------------------------------------------

#

# The following options will be read by the MySQL Server. Make sure that

# you have installed the server correctly (see above) so it reads this

# file.

#

[mysqld]





# The TCP/IP Port the MySQL Server will listen on

port=3306









#Path to installation directory. All paths are usually resolved relative to this.

basedir="E:\Program Files\MySQL\"

#Path to the database root

datadir="E:\Program Files\MySQL\Data"

[WinMySQLadmin]

Server="E:\Program Files\MySQL\bin\mysqld.exe"





# The default character set that will be used when a new schema or table is

# created and no character set is defined

default-character-set=gbk





# The default storage engine that will be used when create new tables when

default-storage-engine=INNODB





# Set the SQL mode to strict

sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"





# The maximum amount of concurrent sessions the MySQL server will

# allow. One of these connections will be reserved for a user with

# SUPER privileges to allow the administrator to login even if the

# connection limit has been reached.

max_connections=100





# Query cache is used to cache SELECT results and later return them

# without actual executing the same query once again. Having the query

# cache enabled may result in significant speed improvements, if your

# have a lot of identical queries and rarely changing tables. See the

# "Qcache_lowmem_prunes" status variable to check if the current value

# is high enough for your load.

# Note: In case your tables change very often or if your queries are

# textually different every time, the query cache may result in a

# slowdown instead of a performance improvement.

query_cache_size=0





# The number of open tables for all threads. Increasing this value

# increases the number of file descriptors that mysqld requires.

# Therefore you have to make sure to set the amount of open files

# allowed to at least 4096 in the variable "open-files-limit" in

# section [mysqld_safe]

table_cache=256





# Maximum size for internal (in-memory) temporary tables. If a table

# grows larger than this value, it is automatically converted to disk

# based table This limitation is for a single table. There can be many

# of them.

tmp_table_size=26M









# How many threads we should keep in a cache for reuse. When a client

# disconnects, the client's threads are put in the cache if there aren't

# more than thread_cache_size threads from before.  This greatly reduces

# the amount of thread creations needed if you have a lot of new

# connections. (Normally this doesn't give a notable performance

# improvement if you have a good thread implementation.)

thread_cache_size=8





#*** MyISAM Specific options





# The maximum size of the temporary file MySQL is allowed to use while

# recreating the index (during REPAIR, ALTER TABLE or LOAD DATA INFILE.

# If the file-size would be bigger than this, the index will be created

# through the key cache (which is slower).

myisam_max_sort_file_size=100G





# If the temporary file used for fast index creation would be bigger

# than using the key cache by the amount specified here, then prefer the

# key cache method.  This is mainly used to force long character keys in

# large tables to use the slower key cache method to create the index.

myisam_sort_buffer_size=52M





# Size of the Key Buffer, used to cache index blocks for MyISAM tables.

# Do not set it larger than 30% of your available memory, as some memory

# is also required by the OS to cache rows. Even if you're not using

# MyISAM tables, you should still set it to 8-64M as it will also be

# used for internal temporary disk tables.

key_buffer_size=40M





# Size of the buffer used for doing full table scans of MyISAM tables.

# Allocated per thread, if a full scan is needed.

read_buffer_size=64K

read_rnd_buffer_size=256K





# This buffer is allocated when MySQL needs to rebuild the index in

# REPAIR, OPTIMZE, ALTER table statements as well as in LOAD DATA INFILE

# into an empty table. It is allocated per thread so be careful with

# large settings.

sort_buffer_size=256K









#*** INNODB Specific options ***

innodb_data_home_dir="E:\Program Files\MySQL\Data\INNODB\"





# Use this option if you have a MySQL server with InnoDB support enabled

# but you do not plan to use it. This will save memory and disk space

# and speed up some things.

#skip-innodb





# Additional memory pool that is used by InnoDB to store metadata

# information.  If InnoDB requires more memory for this purpose it will

# start to allocate it from the OS.  As this is fast enough on most

# recent operating systems, you normally do not need to change this

# value. SHOW INNODB STATUS will display the current amount used.

innodb_additional_mem_pool_size=2M





# If set to 1, InnoDB will flush (fsync) the transaction logs to the

# disk at each commit, which offers full ACID behavior. If you are

# willing to compromise this safety, and you are running small

# transactions, you may set this to 0 or 2 to reduce disk I/O to the

# logs. Value 0 means that the log is only written to the log file and

# the log file flushed to disk approximately once per second. Value 2

# means the log is written to the log file at each commit, but the log

# file is only flushed to disk approximately once per second.

innodb_flush_log_at_trx_commit=1





# The size of the buffer InnoDB uses for buffering log data. As soon as

# it is full, InnoDB will have to flush it to disk. As it is flushed

# once per second anyway, it does not make sense to have it very large

# (even with long transactions).

innodb_log_buffer_size=1M





# InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and

# row data. The bigger you set this the less disk I/O is needed to

# access data in tables. On a dedicated database server you may set this

# parameter up to 80% of the machine physical memory size. Do not set it

# too large, though, because competition of the physical memory may

# cause paging in the operating system.  Note that on 32bit systems you

# might be limited to 2-3.5G of user level memory per process, so do not

# set it too high.

innodb_buffer_pool_size=77M





# Size of each log file in a log group. You should set the combined size

# of log files to about 25%-100% of your buffer pool size to avoid

# unneeded buffer pool flush activity on log file overwrite. However,

# note that a larger logfile size will increase the time needed for the

# recovery process.

innodb_log_file_size=39M





# Number of threads allowed inside the InnoDB kernel. The optimal value

# depends highly on the application, hardware as well as the OS

# scheduler properties. A too high value may lead to thread thrashing.

innodb_thread_concurrency=8









*****************配置文件结束*********************





配置文件也放在了附件里，大家可以根据需要修改。





重点是以下配置，其中datadir的目录名称必须是data，并且好像必须是MySQL目录下的data.之前自己制定了其他目录，一直出现1067的错误。





#Path to installation directory. All paths are usually resolved relative to this.

basedir="E:\Program Files\MySQL\"





#Path to the database root

datadir="E:\Program Files\MySQL\Data"





4、在windows环境变量里加入以下内容（方便执行命令行命令）

新建MYSQL_HOME="E:\Program Files\MySQL\",

在Path里加入%MYSQL_HOME%\bin





5、将mysql注册为windows系统服务。具体操作是在命令行中执行以下命令：

mysqld install MySQL --defaults-file="E:\Program Files\MySQL\my.ini"





移除服务为 mysqld remove





6、第5步成功后，在命令行启动mysql

c:>net start mysql





7、修改root的密码为111111

    c:>mysql -uroot

    mysql> UPDATE user SET password=PASSWORD("111111") WHERE user='root';

　　mysql> FLUSH PRIVILEGES;

　　mysql> QUIT
