1.剛開始安裝mysql參考這個：

2.修改密碼

mysql> use mysql;
     #先把密碼置為空字串；（不讓後面修改密碼會報錯）
mysql> update user set authentication_string="" where user="root";
     #這個重新整理非常有必要；不讓後面執行alter就會出錯
mysql> flush privileges;
mysql> ALTER USER 'root'@'%
 
' IDENTIFIED WITH mysql_native_password BY '密碼';

3.建立使用者以及賦權

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)
