在機器上首次安裝MySQL,
操作系統是win7
mysql 的安裝文件是 zip 格式的,版本是5.7.17
解壓之後,安裝步驟是
1、首先找個文件存放這些安裝程序以及 數據
假設是E:\\mysql
2、把解壓的文件放在E:\\mysql下,並且新建個data文件夾
3、創建環境變量mysql 路徑是E:\\mysql
添加到path 中 %MYSQL%\bin;
4、在解壓的文件夾下有個my-default.ini
的文件,首先拷貝一份,重命名為my.ini
修改文件內容
只修改兩行就行
basedir = E:\\mysql datadir = E:\\mysql\\data
這兩行原先是用#號注釋掉的,
5、用系統管理員身份啟動命令行
輸入mysqld -install
這個是安裝mysql 服務的
6、輸入 mysqld --initialize
這個是因為 自動5.7.7版本之後,windows安裝mysql通過zip解壓的方式,不再包含data 文件夾,這個可以參考官網的介紹
http://dev.mysql.com/doc/refman/5.7/en/windows-initialize-data-directory.html
如果沒有data文件夾,則會在啟動mysql服務的時候起不來,觀察data文件夾下後綴名是.err的文件就可以發現,會報這麼一些錯誤

其實這是因為這些表示放在data文件夾下的,所以我們需要先執行命令mysqld -initialize
在完成mysql 的初始化,這樣的話,mysql會自動完成一些初始化的工作
7、啟動服務 net start mysql
