想说的是，有mysql一定基础的人员，学大数据里的hive、hbase更是可贵！
一、下载
http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.11-winx64.zip
二、安装
1、 解压缩zip包
这里想说的是，我们都知道，关于软件的安装，有两种，msi方式和压缩包解压安装。
关于msi的安装方式，我这里便不多赘述了，见
http://jingyan.baidu.com/article/7e440953d6f0702fc1e2ef61.html
压缩包解压方式的安装：
然后，在这一步有资料说，修改默认配置文件my-default.ini。这里啊，我呢。一般为了专业规范起见，将默认的my-default.ini修改命名为my.ini（这一点，是模仿hadoop/spark）里的配置文件设法。

变成

# 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
3、做如下的修改
# For advice on how to change settings please see

# *** DO NOT EDIT THIS FILE. It‘s a template which will be copied to the

basedir = D:\SoftWare\MySQL\mysql-5.7.11-winx64
datadir = D:\SoftWare\MySQL\mysql-5.7.11-winx64\Data
port = 3306
# 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
4、配置环境变量
新建，MYSQL_HOME，
在windows的path里，添加如下
;%MYSQL_HOME\bin;（注意加分号）
5、将mysql注册为windows系统服务，即初始化mysql
具体操作是在命令行中执行以下命令（需要以管理员身份运行命令行）：
以下命令是在dos命令行中进行的
需要切换到mysq安装的bin目录，
否则，会将服务目录指定为C:\Program Files\MySQL\MySQL Server 5.7\mysqld
这里，顺便，学些dos窗口里的一些常用命令吧！
以管理员的身份进行运行，
C:\Users\Administrator>cd /d D:\
D:\>cd D:\SoftWare\MySQL\mysql-5.7.11-winx64
D:\SoftWare\MySQL\mysql-5.7.11-winx64>cd bin
D:\SoftWare\MySQL\mysql-5.7.11-winx64\bin>
6、自己新建好Data目录
7、执行mysqld.exe --initialize 命令，
D:\SoftWare\MySQL\mysql-5.7.11-winx64\bin>mysqld --initialize
回车
8、执行 mysqld -install命令
D:\SoftWare\MySQL\mysql-5.7.11-winx64\bin > mysqld install
或者
D:\SoftWare\MySQL\mysql-5.7.11-winx64\bin >
mysqld install MySQL --defaults-file=
" D:\SoftWare\MySQL\mysql-5.7.11-winx64\bin\my.ini"
或者
显示Service successfully installed.表示初始化成功!
9、执行mysqld.exe -nt --skip-grant-tables
注意：窗口无反应
10、重新打开dos窗口，执行mysql -u root
11、执行mysql -u root
mysql> use mysql
Database changed
mysql> update user set authtication_string=Password(‘rootroot‘) where user="root"
-> set password=Password(‘rootroot‘)
->
12、在任务管理器中终止mysqld进程，
13、开启mysql服务。
D:\SoftWare\MySQL\mysql-5.7.11-winx64\bin> net start mysql
安装完成。
四、使用
以后，每次，都是到bin

总结：
对于windows里安装Mysql，会出现各种问题，在此，我也是在这基础上，得到了认识和提升！！！
问题：
解决办法1：
mysqld –remove MySQL
转】终于知道为什么我的mysql总是卸载的不干净以及老是找不到my.ini文件
