mysql 5.7.13安装

安装多次均失败，原因竟是MYSQL服务名称不能含有数字！！！

1.复制my-defualt.ini文件改名为my.ini (my-defualt.ini可以删除)

2.my.ini 简单配置信息

3.配置环境变量

新增系统环境变量 MYSQL_HOME;写入值E:\tools\MySQL-5.7.14-win32

在path中中增加;%MYSQL_HOME%\bin;

4.初始化mysql服务

cmd

mysqld -install mysql名

5.初始化data文件包

mysqld --initialize --user=mysql --console

记录最后打印的密码,用于修改密码

net start mysql名

6.修改密码

执行 mysql -u root -p

输入上面打印的密码

7.修改密码 

set password = password('123');

8.刷新权限

flush privileges;

9.退出

quit
