2.修改密码
mysql> use mysql; #先把密码置为空字符串；（不让后面修改密码会报错） mysql> update user set authentication_string="" where user="root"; #这个刷新非常有必要；不让后面执行alter就会出错 mysql> flush privileges; mysql> ALTER USER ‘root‘@‘%‘ IDENTIFIED WITH mysql_native_password BY ‘密码‘;
3.创建用户以及赋权
mysql> create user ‘shenbo‘@‘%‘ identified by ‘$mima...‘; Query OK, 0 rows affected (0.21 sec) mysql> grant all privileges on *.* to ‘shenbo‘@‘%‘ ; Query OK, 0 rows affected (0.06 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)
Linux Redhat 4.4.7 安装 8.0.13 MySQL Community Server
