基本my.ini配置如上圖
cmd 進入 安裝目錄執行
1. mysqld.exe --initialize --basedir=mysql安裝目錄 --datadir=自建的data數據存放目錄
2. mysqld.exe --defaults-file="mysql目錄/my.ini" --console
3. 執行完成後 在data下有一個.err結尾的文件 其中有一行 格式 ：[Server] A temporary password is generated for root@localhost: agEE;3)a(+LR
4.在打開一個cmd mysql -uroot -pagEE;3)a(+LR（紅色為系統給的隨機密碼各不相同）
5.修改密碼 alter user ‘root’@‘localhost’ identified by “新密碼”
