解压安装 Mysql 5.6
1. 下载Windows版本的压缩包
如：mysql-5.6.31-winx64.zip
2. 将文件解压缩到指定目录
如：C:\Program Files\MySQL\MySQL Server 5.6
3. 设置环境变量
将.../bin 添加到系统环境变量 path 中
4. 修改配置文件
默认的配置文件是../my-default.ini，重命名该文件或者自己建立一个my.ini文件
在其中修改或添加配置：
[mysqld]
basedir=C:/Program Files/MySQL/MySQL Server 5.6
datadir=C:/Program Files/MySQL/MySQL Server 5.6/data
5. 安装windows服务
进入到bin目录中，输入 mysqld -install 安装服务
如果不进入bin目录，install能成功，服务能注册，但服务无法启动，提示找不到文件
install指令默认会按照如下顺序读取指定配置文件:
C:\Windows\my.ini
C:\Windows\my.cnf
C:\my.ini
C:\my.cnf
C:\Program Files\MySQL\MySQL Server 5.6\my.ini
C:\Program Files\MySQL\MySQL Server 5.6\my.cnf
C:\Users\Administrator>mysqld -install
Service successfully installed.
basedir = C:\Program Files\MySQL\mysql-5.6.31-winx64
datadir = C:\Program Files\MySQL\mysql-5.6.31-winx64\data
6. 初始数据目录
进入到bin目录中，输入 mysqld --initialize 初始化数据目录
（好像是可以不需要）
C:\Users\Administrator>mysqld --initialize
2016-11-16 16:54:03 0 [Warning] TIMESTAMP with implicit DEFAULT value is depreca
ted. Please use --explicit_defaults_for_timestamp server option (see documentati
on for more details).
2016-11-16 16:54:03 0 [Note] mysqld (mysqld 5.6.31) starting as process 2564 ...
7. 启动服务
net start mysql
# 停止服务用
net stop mysql
8. 修改密码
# 指定root用户登录否则没有权限
mysql -u root
# 切换到mysql数据库
use mysql;
# 默认是没有密码的
mysql> select Host,User,Password from user;
+-----------+------+----------+
| Host | User | Password |
+-----------+------+----------+
| localhost | root | |
| 127.0.0.1 | root | |
| ::1 | root | |
| localhost | | |
+-----------+------+----------+
4 rows in set (0.00 sec)
# 修改密码
mysql> update mysql.user set password=password('root') where user='root';
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3 Changed: 3 Warnings: 0
# 刷新权限
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
# 再查看user表
mysql> select Host,User,Password from user;
+-----------+------+-------------------------------------------+
| Host | User | Password |
+-----------+------+-------------------------------------------+
| localhost | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| 127.0.0.1 | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| ::1 | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| localhost | | |
+-----------+------+-------------------------------------------+
4 rows in set (0.00 sec)
## 可以用客户端工具进行测试
# 远程访问，Host为%
mysql> grant all privileges on *.* to 'root'@'%' identified by 'root' with grant
option;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
# 再看多了一条记录
mysql> select Host,User,Password from user;
+-----------+------+-------------------------------------------+
| Host | User | Password |
+-----------+------+-------------------------------------------+
| localhost | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| 127.0.0.1 | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| ::1 | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| localhost | | |
| % | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |

解压安装 MySQL 5.7
1. 下载Mysql 5.7的ZIP包
地址：
https://dev.mysql.com/downloads/file/?id=478884
https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.23-winx64.zip
2. 选择安装位置，解压缩
如解压到：D:\mysql\mysql-5.7.23-winx64
如果想在其他目录直接执行mysql命令，则需要将bin加入到环境变量
2. 创建my.ini文件
在安装目录（D:\mysql\mysql-5.7.23-winx64）创建my.ini文件，填入如下内容
纯文本文件，可以使用任何文本编辑器进行编辑
[mysqld]
# set basedir to your installation path
basedir=D:/mysql/mysql-5.7.23-winx64
# set datadir to the location of your data directory
datadir=D:/mysql/mysql-5.7.23-winx64/data
如果使用反斜杆需要两个
[mysqld]
# set basedir to your installation path
basedir=D:\\mysql\\mysql-5.7.23-winx64
# set datadir to the location of your data directory
datadir=D:\\mysql\\mysql-5.7.23-winx64\\data
3. 初始化数据目录
cd D:\mysql\mysql-5.7.23-winx64
D:\mysql\mysql-5.7.23-winx64>bin\mysqld --initialize --console
# 会生成临时密码
# [Note] A temporary password is generated for root@localhost: r!i*sp)-E9hA
4. 启动Mysql
D:\mysql\mysql-5.7.23-winx64\bin>mysqld.exe --console
......
......

Version: '5.7.23' socket: '' port: 3306 MySQL Community Server (GPL)
这种方式启动直接 CTRL + C 停止即可
不加 --console 则输出信息在日志文件夹中
5. 进入mysql，并修改密码
cd bin
mysql -uroot -p
# 输入上面的临时密码
#进入mysql，修改密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';
# 退出重新登录
6. 停止mysql
>mysqladmin.exe -uroot -p shutdown
#输入root密码
7. 作为Windows服务
需要想将bin目录加入到环境变量
没有进行测试，通过命令行方式启动更加可控
# 安装服务
bin\mysqld --install
# 删除服务
bin\mysqld --remove
关于登录和密码
Mysql 5.6
# 修改密码
set password for 'root'@'localhost' =password('root');
# 设置远程登录
grant all privileges on *.* to 'root'@'%' identified by 'root' with grant option;
flush privileges;
# 创建新用户
create user 'hinge'@'%' identified by 'hinge';
grant all privileges on *.* to hinge@'%' identified by 'hinge';
flush privileges;
# 不指定时默认是%*
create user hinge identified by 'hinge';
grant all privileges on *.* to hinge identified by 'hinge';
flush privileges;
grant all privileges on *.* to hinge@'localhost' identified by 'hinge';
flush privileges;
# 刷新权限
flush privileges;
Mysql 5.7
在配置文件[mysqld]字段下增加skip-grant-tables 字段，用以忽略权限验证
使用mysql -u root -p 登录数据， 密码直接回车
修改[mysql]数据库，user表的authentication_string字段
update mysql.user set authentication_string=password('root') where user='root'；
flush privileges;

这个时候的mysql5.7 小版本已经到了32 了
下载地址：
https://dev.mysql.com/downloads/mysql/5.7.html
缺少dll的问题
运行mysqld 时，系统提示“由于找不到MSVCR120.dll，无法继续执行代码。重新安装程序可能会解决此问题。”
