MySQL5.7.9安装步骤（Windows7 64位）
1. 解压MySQL压缩包
将下载的MySQL压缩包解压到自定义目录下,我的解压目录是:
"D:\Program Files\mysql-5.7.9-win32"
将解压目录下默认文件 my-default.ini 拷贝一份，改名 my.ini
复制下面的配置信息到 my.ini 保存
#如果没有my-default.ini,可自己新建my.ini或者从其他地方中获取
#########################################################
[client]
port=3306
default-character-set=utf8
[mysqld]
port=3306
character_set_server=utf8
#解压目录
basedir=D:\Program Files\mysql-5.7.9-win32
#解压目录下data目录
datadir=D:\Program Files\mysql-5.7.9-win32\data
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[WinMySQLAdmin]
D:\Program Files\mysql-5.7.9-win32\bin\mysqld.exe
#########################################################
2. 添加环境变量
操作如下：
1）右键单击我的电脑->属性->高级系统设置(高级)->环境变量
点击系统变量下的新建按钮
输入变量名：MYSQL_HOME
输入变量值：D:\Program Files\mysql-5.7.9-win32
#即为mysql的自定义解压目录。
2）选择系统变量中的Path
点击编辑按钮
在变量值中添加变量值：;%MYSQL_HOME%\bin
注意是在原有变量值后面加上这个变量，用;隔开，不能删除原来的变量值
3. 1）从控制台进入到MySQL解压目录下的 bin 目录下：
2）输入服务安装命令：
1. mysqld --console
2. mysqld --initialize
3. mysqld install
安装成功后会提示服务安装成功。
#注： #执行这几步，是因为在MySQL5.7.9中没有data文件夹，需要用这几个命令产生data文件夹
#移除服务命令为：mysqld remove
4. 启动MySQL服务
方法一：
启动服务命令为：net start mysql
方法二：
打开管理工具 服务，找到MySQL服务。
通过右键选择启动或者直接点击左边的启动来启动服务。
5. 修改 root 账号的密码
1. 修改MySQL的配置文件（my.ini）,在[mysqld]下添加一行skip-grant-tables
2. mysql 重启后，即可直接用 mysql -u root -p 进入(此时密码为空)
3. mysql> update mysql.user set authentication_string=password('123qaz') where user='root' and Host = 'localhost';
4. mysql> flush privileges;
5. mysql> quit;
6. 将/etc/my.cnf文件还原(删除skip-grant-tables这一行)，重新启动 mysql
7. 这个时候可以使用 mysql -u root -p '123qaz' 进入了
8. mysql>SET PASSWORD = PASSWORD('123456'); 设置新密码
MySQL5.6.11安装步骤（Windows7 64位）
1. 下载MySQL Community Server 5.6.112. 解压MySQL压缩包
将以下载的MySQL压缩包解压到自定义目录下。
变量名：MYSQL_HOME
变量值：D:\Program Files\mysql-5.6.11-winx64
即为mysql的自定义解压目录。
再在Path中添加 %MYSQL_HOME%\bin
将mysql注册为windows系统服务
操作如下：
1）从控制台进入到MySQL解压目录下的 bin 目录下：
2）输入服务安装命令：
mysqld install MySQL --defaults-file="D:\Program Files\mysql-5.6.11-winx64\my-default.ini"
如果打开services.msc 服务控制面板看到 mysql这个服务的 可执行路径有问题，可查找，关键字my-default.ini 找到注册表 HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\MySQL 下的 ImagePath 键把，路径改正确
如果出现Install/Remove of the Service Denied!
是因为WINDOW 7 跟 vista 的权限更严格
进入 C:\Window\System32 找到CMD.EXE 右键选择 以管理员身份 进行，再进入相应目录执行命令，一切就OK了。
安装成功后会提示服务安装成功。
注：my-default.ini文件在MySQL解压后的根目录下，如果没有，可从其他地方中获取。
移除服务命令为：mysqld remove
方法一：
启动服务命令为：net start mysql
方法二：
打开管理工具 服务，找到MySQL服务。
通过右键选择启动或者直接点击左边的启动来启动服务。
刚安装完成时root账号默认密码为空，此时可以将密码修改为指定的密码。如：123456
方法一：
c:>mysql –uroot
mysql>show databases;
mysql>use mysql;
mysql>UPDATE user SET password=PASSWORD("123456") WHERE user='root';
mysql>FLUSH PRIVILEGES;
mysql>QUIT
方法二：
利用第三方管理工具进行密码修改。如Navicat for MySQL
mysql5安装配置
一、下载mysql5免安装版本
my-small.ini：用于小型系统的配置文件，MYSQL运行内存小于等于64M；
my-medium.ini：用于中等系统的配置文件，MYSQL运行内存在32M - 64M之间；
my-large.ini：用于大型系统的配置文件，MYSQL运行内存在512M，该系统主要运行MYSQL数据库；
my-huge.ini：用于巨型系统的配置文件，MYSQL运行内存在1G-2G之间，该系统主要运行MYSQL数据库；
my-innodb-heavy-4G.ini：4G的RAM，只支持事务，很少连接数，很大的查询量。
我们只需要从中选择一种将其复制到桌面改名为my.ini文件，此文件就为MYSQL数据库默认的配置文件，将其剪切放在mysql-5.6.11目录下。
目录下新建一个my.ini，拷贝my-small.ini代码至my.ini；修改后如下(中文说明为添加部分)：
# 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 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
# The TCP/IP Port the MySQL Server will listen on
port = 3306 //端口
#socket = /tmp/mysql.sock
[mysql]
# 设置mysql客户端的字符集

四、然后编写启动脚本startup.bat
在D:\mysql-5.1.42\bin路径下编写startup.bat：
@echo off
echo start mysql5 on localhost
mysqld --install mysql5 --defaults-file=D:\mysql-5.1.42\my.ini //将服务注册到win服务中去
net start mysql5 //启动mysql
pause
注册服务用
mysqld --install mysql5 --defaults-file="C:\temp\TopSoft\service\mysql\my.ini"
或：mysqld-nt.exe --install mysql5 --defaults-file="..\my.ini"
五、停止脚本stop.bat
在D:\mysql-5.1.42\bin路径下编写stop.bat：
@echo off
echo stop mysql5
net stop mysql5
mysqld --remove mysql5
pause
删除服务：
mysqld-nt --remove mysql5
六、配置完毕后检查
双击D:\mysql-5.1.42\bin路径下的startup.bat批处理文件，在系统服务中有一个mysql5的服务，并且已经启动，然后测试下数据库的安装情况，在dos窗口下，进入D:\>cd D:\mysql-5.1.42\bin路径下，输入mysqlshow，即可显示数据库信息，
示例如下：
Microsoft Windows XP [版本 5.1.2600]
(C) 版权所有 1985-2001 Microsoft Corp.
C:\Documents and Settings\guoy>d:
D:\>cd D:\mysql-5.1.42\bin
D:\mysql-5.1.42\bin>mysqlshow
+--------------------+
| Databases |
+--------------------+
| information_schema |
| test |
+--------------------+
D:\mysql-5.1.42\bin>
如上信息说明数据库安装成功还有其他测试命令：
mysqlshow -u root mysql
mysqladmin -u root version status proc
登陆：
mysql -u root -p
输入密码即可
选择数据库：use mysql
修改密码：update user set Password=password('123456') where user='root';
flush privileges;
：net start
启动服务：net start mysql5
停止服务：net stop mysql5

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：

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
