windows系统下安装最新mysql 5.7.13解压版

最近因为需要测试mysql的多种主从配置方案，所以要安装多个mysql。为了更好的应用机器，干脆就在一台windows机器上安装了多个mysql，用不同的端口号区别开。那么，最好的选择自然就是安装多个mysql解压版，而不是那种msi安装版，可以达到绿色版的用后即焚效果。

系统环境：win 7，32位系统
mysql版本：5.7.13社区版
mysql下载地址：http://dev.mysql.com/downloads/mysql/,我下载的是大小为296.5M的
Windows (x86, 32-bit), ZIP Archive
mysql官方安装文档：http://dev.mysql.com/doc/refman/5.7/en/windows-install-archive.html

下面开始安装和配置步骤：
1.将下载下来的文件mysql-5.7.13-win32.zip解压至一个分区或者目录中，例如c盘。解压完，会发现在mysql-5.7.13-win32目录下有一个my-default.ini文件。将此文件放到你想放置的目录下，并改名为my.ini，然后编辑之，打开basedir，datadir，port等项，按如下配置：

basedir = F:\\mysql-5.7.13-win32
datadir = F:\mysql-5.7.13-win32\\data
port = 3306

2.在windows命令行下进入mysql的解压目录，然后执行

F:\mysql-5.7.13-win32\bin>mysqld --defaults-file=F:\mysql-5.7.13-win32\my.ini --initialize

按照官方安装文档的说明，在初始化完，会给出一个root账号的临时随机密码，下面这段话摘录自官方文档：

With --initialize but not --initialize-insecure, the server generates a random password, marks it as expired, and writes a message displaying the password:

[Warning] A temporary password is generated for root@localhost:
iTag*AfrH5ej

可是我运行完这个命令之后，什么提示也没有出现啊！

没管那么多，我开始接着启动mysql

F:\mysql-5.7.13-win32\bin>mysqld --console

在命令行显示了以下信息：

mysql应该是顺利启动了，然后我用mysql客户端软件进行登录，问题来了，问题再一次如约而至。。。
登录需要口令，而我却从没得到一个临时生成的口令！这官方安装文档也太坑爹了吧。

3.这下又陷入一筹莫展了，思考了一会儿，我想要不就试试--initialize-insecure参数吧，毕竟insecure是不安全的意思。。。

于是我停止mysql，删除了已经初始化的data目录，执行下面的命令，重新进行初始化：

F:\mysql-5.7.13-win32\bin>mysqld --defaults-file=F:\mysql-5.7.13-win32\my.ini --initialize-insecure

和之前一样，还是没有出现任何提示就运行完成了。
再次启动mysql

F:\mysql-5.7.13-win32\bin>mysqld --console

然后我再次使用navicat客户端软件进行登录，将口令设置为空，这次成功登录mysql！
当然，登录后记得修改root密码。

4.最后，解压版安装完，发现整个mysql已经达到了1.66G，实在是很占用硬盘空间。
当然，接下来就可以继续以解压方式安装3307,3308,3309。。。了。
