修改密碼

mysql5.6之前修改密碼(字段password)

mysql> use mysql;

mysql> update user set password=password(‘123‘) where user=‘root‘ and host=‘localhost‘;

mysql> flush privileges;

mysql 5.7.22版本修改密碼(字段是authentication_string)

mysql> use mysql;

mysql>update user authentication_string=password(‘root123‘) where user=‘root‘

mysql> flush privileges; --不重啟MySQL服務生效
