1.1 
下载

http://dev.mysql.com/downloads/mysql/
 
下载地址, 在下拉框中选择相应的版本

1.2 
安装

下载下来的绿色安装包，直接解压为 E:\mysql

1.3 
编辑 my.ini 文件，

将 mydefault.ini copy 一份出来，就该其中的参数.

在 mysqld 中加入如下内容

  basedir= E:\mysql\

  datadir= E:\mysql\data

  port=3306

#skip-grant-tables

E:\mysql\bin mysqld –initialize

2016-09-06T13:57:01.349392Z 0 [Warning] TIMESTAMP with implicit
DEFAULT value is

 deprecated. Please use
–explicit_defaults_for_timestamp server option (see doc

umentation for more details).

2016-09-06T13:57:01.353393Z 0
[ERROR]
–initialize specified but the data direct

ory has files in it.
Aborting.

2016-09-06T13:57:01.354393Z 0 [ERROR] Aborting

出现了如上错误，是由于之前在
data 文件夹中有文件导致的，删掉 data 下所有的文件，重新执行 mysqld.exe –initialize 命令 ok

E:\mysql\bin mysqld.exe –initialize

E:\mysql\bin mysqld.exe –install

没办法修改密码吧

在 mysqld 下加入

skip-grant-tables

E:\mysql\bin net start mysql

mysql update user set

出现这个错误是由于 mysql 5.7 后 password 栏位变成 authentication_string

mysql update user set
authentication_string=password(mysql) where user= root
