距离上次安装MySQL已经过去好久了。步骤这些，有可能会忘记。简单记录一下吧。(参考了一些网络上的博客。)

1.mysql-5.7.5-m15-winx64.zip下载

官方网站下载地址：

http://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.7-rc-winx64.zip

2.解压到D:\MySqlDataBase

3.在D:\MySqlDataBase\mysql-5.7.5-m15-winx64下新建my.ini配置文件

内容如下：

# For advice on how to change settings please see

# http://dev.mysql.com/doc/refman/5.7/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.

# [mysqld]

# 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 = .....

# datadir = .....

# 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

####################配置文件结束###################

重点是以下配置，其中datadir的目录名称必须是：

D:\MySqlDataBase\ mysql-5.7.5-m15-winx64/data/。

4.在windows系统环境变量path，加入如下内容

D:\mysql\mysql-5.7.5-m15-winx64\bin;(注意加分号)

变量名：MYSQL_HOME

变量值：D:\Program Files\mysql-5.7.5-m15-winx64

即为mysql的自定义解压目录。

再在Path中添加  %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(需要以管理员身份运行命令行)：

需要切换到bin目录，否则，会将服务目录指定为C:\Program Files\MySQL\MySQL Server 5.7\mysqld

增加服务命令为：

mysqld install MySQL --defaults-file="D:\mysql\mysql-5.7.5-m15-winx64\my.ini"

移除服务命令为：

mysqld remove

mysqld install MySQL5.7.7 --defaults-file="E:\Database\MySQL\mysql-5.7.7-rc-winx64\my.ini"

mysqld remove MySQL5.7.7

net start MySQL5.7.7

net stop  MySQL5.7.7

6.第5步成功后，打开系统服务管理

可以看到mysql系统服务

在命令行启动mysql命令为：net start mysql

关闭mysql命令为：net stop mysql

7.修改root的密码为wenthink

命令行执行：mysql –uroot

mysql>show databases;

mysql>use mysql;

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

mysql>FLUSH PRIVILEGES;

mysql>QUIT

远程登陆配置

允许root用户在任何地方进行远程登录，并具有所有库任何操作权限，具体操作如下：

1)在本机先使用root用户登录mysql：

命令行执行：mysql -u root -p

输入密码(第7步中设置的密码)：wenthink

2)进行授权操作：

mysql>GRANT ALL PRIVILEGES ON *.* TO

'root'@'%' IDENTIFIED BY 'youpassword' WITH GRANT OPTION;

重载授权表：

mysql>FLUSH PRIVILEGES;

退出mysql：

mysql>quit
