Win7下安装Mysql方法
下载mysql安装包
进行配置
安装包名称：mysql-5.6.12-winx64.zip
解压安装包，记路径，我就直接放在桌面了，并且做了重命名
C:\Users\hy\Desktop\mysql
修改mysql目录下的配置文件my.ini如下：
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
character-set-server=utf8
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
basedir = C:\Users\hy\Desktop\mysql
datadir = C:\Users\hy\Desktop\mysql\data
# port = .....
# server_id = .....
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
安装mysql
以管理员身份启动cmd，切换到目录C:\Users\hy\Desktop\mysql\bin
安装mysql：mysqld.exe –install（CMD中执行后，如果报拒绝，则需要用管理员权限运行CMD，然后执行该命令）
往往都是权限不够导致的
以管理员身份运行的方式：找到运行程序cmd.exe,右键以管理员方式运行
C:\Windows\System32
启动MySQL
以管理员身份启动cmd，切换到目录D:/mysql-5.6.12-win32/bin
启动mysql服务：net start MySQL
（若想在cmd命令中直接运行指令，而不用进入bin目录下，需要在环境变量中增加路径，如图：
PS：系统默认的Mysql是自启动的，修改为手工启动的方法：
进入本机的“服务”，修改为手动启动即可，如图：
执行命令
登录mysql
mysql -u root -p
输入密码(密码为空，直接回车)，即可登录。
修改root密码为123456：
mysql > set password = password('123.com');
mysql > flush privileges;
mysql > exit
停止mysql服务
net stop MySQL
卸载mysql服务
mysqld.exe --remove
