2. 環(huán)境變量
新增環(huán)境變量 MYSQL_HOME

安裝和初始化
進入 mysql 的 bin 文件夾以管理員身份運行 cmd
執(zhí)行
mysqld install，在服務(wù)中會出現(xiàn) MySQL 服務(wù)（如果不用管理員身份運行，將會因為權(quán)限不夠而出現(xiàn)錯誤：Install/Remove of the Service Denied!）
（Windows 移除服務(wù)命令：sc delete mysql）image.pngimage.png執(zhí)行
mysqld --initialize --console（此時會在 mysql 根目錄下生成 data 文件夾）image.pngimage.png
“qZ*Hyh=-u59=”為 root 賬號初始密碼，記住這個密碼。
如果忘記或者沒記住，刪掉初始化的 data 目錄，再執(zhí)行一遍初始化命令（mysqld --initialize --console），又會重新生成。當(dāng)然也可以使用安全工具強制改密碼，用什么方法，自己隨意。
啟動 MySQL
cmd 中繼續(xù)輸入
net start mysql啟動 mysqlimage.png停止 MySQL：
net stop mysql
修改 MySQL 賬號密碼
登錄
（密碼是生成的 “qZ*Hyh=-u59=”）：
mysql -uroot -p
image.png修改密碼執(zhí)行以下命令：
ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
flush privileges;
