環境：win10 64位?
mysql版本:mysql-5.7.9-winx64.zip （http://dev.mysql.com/downloads/mysql/）
首先聲明一下，5.7.9這個版本的配置方式跟之前的免安裝版配置不一樣。(.msi安裝版和其他版本的可以忽略該方法)?
步驟：?
1，在官網上下載了mysql-5.7.9-winx64.zip 這個文件之后， 解壓到指定目錄：F:\Java\mysql\mysql-5.7.9-winx64?
2，在F:\java\mysql\mysql-5.7.9-winx64 目錄創建data文件夾?
3，將my.default.ini改名為my.ini放到bin目錄，并且在my.ini目錄加入如下代碼：?
basedir = F:\java\mysql\mysql-5.7.9-winx64?
datadir = F:\java\mysql\mysql-5.7.9-winx64\data?
port = 3306?
4，配置環境變量，path=F:\java\mysql\mysql-5.7.9-winx64\bin?
5，以管理員權限打開命令行，進入到F:\java\mysql\mysql-5.7.9-winx64\bin目錄，?
執行: mysqld –initialize –user=mysql –console?
6，先執行以上命令, 會生成庫. 注意有個臨時密碼, 要記下來.
F:\java\mysql\mysql-5.7.9\bin>mysqld --initialize --user=mysql --console

7,如本次執行的臨時密碼是：v2toK7w,TJ_<?
8, 執行安裝服務命令： mysqld –install?
9，執行啟動服務命令： net start mysql?
10，到此，mysql就安裝好了。 然后執行:mysql -uroot -p?
11,輸入剛才的密碼:v2toK7w,TJ_<?
12,執行改密碼命令：set password = password(‘password’)?
13，至此，就root賬號的密碼就被你改成password了
