環(huán)境變量與開(kāi)機(jī)自啟:

啟動(dòng)數(shù)據(jù)庫(kù):
[root@localhost mysql]# /etc/init.d/mysqld start
修改密碼與創(chuàng)建用戶(hù),8.0已取消grant權(quán)限自動(dòng)創(chuàng)建用戶(hù),要用create user創(chuàng)建用戶(hù)再用grant賦予權(quán)限:

ps:MySql8.0.19 安裝采坑記錄
1、ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
解決方式如下:
mysql> ALTER USER USER() IDENTIFIED BY 'Xiaoming250';
2、修改root密碼
ALTER user 'root'@'localhost' IDENTIFIED BY '新密碼';
