MySQL5.7.14的免安装配置

首先浏览器地址栏输入www.oracle.com进入Oracle官网。

然后选择Downloads–>MySQL

然后再最底下选择MySQL(GPL)，GPL表示通用免费开源的版本，与之相对的是Commercial,表示商业收费版。

然后选择5.7.14版本，根据自己的机器下对应的32位或64位zip软件。

好，软件下好了，接下来讲下安装。
5.7.14版是一个免安装的版本，直接解压缩到任意位置，本人演示的是d盘根目录。

1.解压mysql-5.7.14-win64.zip文件。

2.在解压出来的文件夹中的BIN文件夹加入环境变量。

3.在解压出来的文件夹里建立data文件夹。

4.复制my-default.ini并将复制后的副本改名为my.ini文件，之后对my文件进行修改，将basedir和datadir进行相应的路径赋值。
本人的my.ini文件如下，如有需要可适当参考：

# For advice on how to change settings please see# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html# *** DO NOT EDIT THIS FILE.

5.在CMD中，进入建立的data文件夹，然后执行“mysqld –initialize”进行data文件夹的初始化。

6.CMD进入bin文件夹中，执行“mysqld -install”进行服务安装。

7.接着输入“net start mysql”进行服务的启动。

其中，默认的初始化密码在用“mysqld –initialize”初始化后的data文件夹的*.pid文件中。用记事本打开，按住Ctrl+F,弹出查找对话框，输入root查找，可以看到初始密码就在后面。

首先使用默认密码登陆数据库，然后使用 ” set password = password(‘你自己的密码’); “ 语句即可。
