一、下載mysql 5.7.11 zip 安裝包
本機以win7 64位系統為例，如果是32位系統，請下載32位的安裝包
http://dev.mysql.com/downloads/mysql/
選擇 Windows (x86, 64-bit), ZIP Archive 下載包
二、解壓安裝包 ｜ Extracting the Install Archive
|
1
|
D:\victor.min\software\mysql-5.7.11-winx64 #我的解壓目錄 |
三、創建一個空文件夾，命名為data， 也可以隨便命名，用來存放數據
|

# 本機創建在 D:\victor.min\software\mysql-5.7.11-winx64 目錄下，所以最后會看到D:\victor.min\software\mysql-5.7.11-winx64\data #此文件夾后面會有用到 |
四、配置一個自己的啟動配置文件 ｜ Creating an Option File
如果自己用沒什么特別的，就把 D:\victor.min\software\mysql-5.7.11-winx64\my-default.ini 文件copy一份，重新命名為 my.ini ，修改里面的幾個參數就好了 ｜｜ 配置文件如下

五、初始化數據目錄 Initializing the Data Directory
當然，按照mysql官方文檔給出的步驟還有一步 Selecting a MySQL Server Type，就是選擇用 mysqld 還是 mysqld-debug ｜命令如下
|
1
|
mysqld --defaults-file="D:\victor.min\software\mysql-5.7.11-winx64\my.ini" --initialize-insecure |
注：
1、這個命令很重要，它會初始化 data 目錄，在執行此命令前請先把data目錄下的所有文件先刪除，否則會失敗
2、可以選擇用 --initialize-insecure 或者 --initialize 來初始化，--initialize-insecure 初始化root密碼為空，如果用 --initialize來初始化，會產生一個隨機密碼
執行成功后你會在data目錄 下看到 mysql，perofrmance_schema，sys目錄，同時還會有一些文件
六、安裝 mysql 服務
|
1
|
mysqld -install |
七、啟動 mysql 服務
|
1
|
net start mysql |
到這里，mysql服務就啟動好，我們就可以用root進入 mysql
|
1
|
mysql -u root -p |
為了方便，最好將mysql配置到環境變量中去
后記：
如果中途有什么步驟失敗，一定要執行 mysql 移除命令，然后刪除 data 目錄下的所有文件
|
1
|
mysqld -remove |
特別提醒：5.7 和 5.6 不太相同，要自己初始化數據 data 目錄，不然啟動不會成功
mysql 安裝完后可能會用到的語句
