windows系統下安裝最新mysql 5.7.13解壓版

最近由於須要測試mysql的多種主從配置方案，因此要安裝多個mysql。爲了更好的應用機器，乾脆就在一臺windows機器上安裝了多個mysql，用不一樣的端口號區別開。那麼，最好的選擇天然就是安裝多個mysql解壓版，而不是那種msi安裝版，能夠達到綠色版的用後即焚效果。

系統環境：win 7，32位系統
mysql版本：5.7.13社區版
mysql下載地址：http://dev.mysql.com/downloads/mysql/,我下載的是大小爲296.5M的
Windows (x86, 32-bit), ZIP Archive
mysql官方安裝文檔：http://dev.mysql.com/doc/refman/5.7/en/windows-install-archive.html

下面開始安裝和配置步驟：
1.將下載下來的文件mysql-5.7.13-win32.zip解壓至一個分區或者目錄中，例如c盤。解壓完，會發如今mysql-5.7.13-win32目錄下有一個my-default.ini文件。將此文件放到你想放置的目錄下，並更名爲my.ini，而後編輯之，打開basedir，datadir，port等項，按以下配置：

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

2.在windows命令行下進入mysql的解壓目錄，而後執行

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

按照官方安裝文檔的說明，在初始化完，會給出一個root帳號的臨時隨機密碼，下面這段話摘錄自官方文檔：

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

但是我運行完這個命令以後，什麼提示也沒有出現啊！

沒管那麼多，我開始接着啓動mysql

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

在命令行顯示瞭如下信息：

mysql應該是順利啓動了，而後我用mysql客戶端軟件進行登陸，問題來了，問題再一次如約而至。。。
登陸須要口令，而我卻從沒獲得一個臨時生成的口令！這官方安裝文檔也太坑爹了吧。

3.這下又陷入束手無策了，思考了一下子，我想要不就試試--initialize-insecure參數吧，畢竟insecure是不安全的意思。。。

因而我中止mysql，刪除了已經初始化的data目錄，執行下面的命令，從新進行初始化：

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

和以前同樣，仍是沒有出現任何提示就運行完成了。
再次啓動mysql

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

而後我再次使用navicat客戶端軟件進行登陸，將口令設置爲空，此次成功登陸mysql！
固然，登陸後記得修改root密碼。

4.最後，解壓版安裝完，發現整個mysql已經達到了1.66G，實在是很佔用硬盤空間。 固然，接下來就能夠繼續以解壓方式安裝3307,3308,3309。。。了。
