MySQL 5.7.9 免安装配置
MySQL 5.7.9 免安装配置
环境：win10 64位mysql版本:mysql-5.7.9-winx64.zip （http://dev.mysql.com/downloads/mysql/）
首先声明一下，5.7.9这个版本的配置方式跟之前的免安装版配置不一样。(.msi安装版和其他版本的可以忽略该方法)
步骤：
1，在官网上下载了mysql-5.7.9-winx64.zip 这个文件之后， 解压到指定目录：F:\java\mysql\mysql-5.7.9-winx64
2，在F:\java\mysql\mysql-5.7.9-winx64 目录创建data文件夹
3，将my.default.ini改名为my.ini放到bin目录，并且在my.ini目录加入如下代码：
basedir = F:\java\mysql\mysql-5.7.9-winx64
datadir = F:\java\mysql\mysql-5.7.9-winx64\data
port = 3306
4，配置环境变量，path=F:\java\mysql\mysql-5.7.9-winx64\bin
5，以管理员权限打开命令行，进入到F:\java\mysql\mysql-5.7.9-winx64\bin目录，
执行: mysqld --initialize --user=mysql --console
6，先执行以上命令, 会生成库. 注意有个临时密码, 要记下来.
F:\java\mysql\mysql-5.7.9\bin>mysqld --initialize --user=mysql --console
