http://dev.mysql.com/downloads/mysql/    下載地址 , 在下拉框中選擇相應的版本

 

1.2    安裝

下載下來的綠色安裝包，直接解壓為 E:\mysql

 

1.3    編輯 my.ini 檔案，

將 mydefault.ini copy 一份出來，就該其中的引數 .

在 mysqld 中加入如下內容

      datadir="E:\mysql\data"

      port=3306

#skip-grant-tables

 

E:\mysql\bin>mysqld --initialize

ERROR 1054 (42S22): Unknown column 'password' in 'field list'

 

出現這個錯誤是由於 mysql 5.7 後 password 欄位變成 authentication_string

 

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

;
