mysql安装与配置（以mysql-5.7.10-winx64为例）

一、在官网上下载相应的mysql安装包，本人下载的是：mysql-5.7.10-winx64 （Windows (x86, 64-bit), ZIP Archive）

附下载地址：http://dev.mysql.com/downloads/mysql/

二、将下载后的文件解压到指定目录（如：E:\Sun\SSM\mysql-5.7.10-winx64），并在该目录下新建一个my.ini文件基内容如下（注意目录要与你解压的对应）

[mysql]

# 设置mysql客户端默认字符集

default-character-set=utf8 

[mysqld]

#设置3306端口

port = 3306 

# 设置mysql的安装目录

basedir=E:\Sun\SSM\mysql-5.7.10-winx64

# 设置mysql数据库的数据的存放目录

#datadir=E:\Sun\SSM\mysql-5.7.10-winx64\data

# 允许最大连接数

max_connections=200

# 服务端使用的字符集默认为8比特编码的latin1字符集

character-set-server=utf8

# 创建新表时将使用的默认存储引擎

default-storage-engine=INNODB 

三、进入cmd界面

1、安装mysql

C:\Users\Administrator>e:

E:\>cd Sun

E:\Sun>cd SSM

E:\Sun\SSM>cd mysql-5.7.10-winx64

E:\Sun\SSM\mysql-5.7.10-winx64>cd bin

E:\Sun\SSM\mysql-5.7.10-winx64\bin>mysqld --install

2、初始化开生成data文件夹

C:\Users\Administrator>e:

E:\>cd Sun

E:\Sun>cd SSM

E:\Sun\SSM>cd mysql-5.7.10-winx64

E:\Sun\SSM\mysql-5.7.10-winx64>cd bin

E:\Sun\SSM\mysql-5.7.10-winx64\bin>mysqld --initialize

3、启动服务（也可以在服务中去手动启动）

C:\Users\Administrator>e:

E:\>cd Sun

E:\Sun>cd SSM

E:\Sun\SSM>cd mysql-5.7.10-winx64

E:\Sun\SSM\mysql-5.7.10-winx64>cd bin

E:\Sun\SSM\mysql-5.7.10-winx64\bin>net start mysql

4、查看默认密码及修改密码（在解压目录：E:\Sun\SSM\mysql-5.7.10-winx64\data下有个计算机名.err的文件,我的计算机名是Sun ）

4.1 Sun.err （其中有个临时密码：yCo2*#ZnQ2Ma）

2016-01-05T10:53:53.345887Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

2016-01-05T10:53:59.992267Z 1 [Note] A temporary password is generated for root@localhost: yCo2*#ZnQ2Ma

4.2 修改密码

C:\Users\Administrator>e:

E:\>cd Sun

E:\Sun>cd SSM

E:\Sun\SSM>cd mysql-5.7.10-winx64

E:\Sun\SSM\mysql-5.7.10-winx64>cd bin

E:\Sun\SSM\mysql-5.7.10-winx64\bin>mysql -u root -p

然后输入临时密码，输入正确后会有mysql>

再输入： set password for root@localhost = password('12345'); //注意分号不能少，将密码设置成12345
