修改mysql連接的密碼

mysql8.0修改密碼：

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '你的password';

msyql開啟實現遠程連接

   將host字段的值改為%就表示在任何客戶端機器上能以root用戶登錄到mysql服務器，建議在開發時設為%。   
   update user set host = ’%’ where user = ’root’;

   將權限改為ALL PRIVILEGES

mysql> use mysql;
Database changed
mysql> grant all privileges  on *.* to root@'%' identified by "password";
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> select host,user,password from user;
+--------------+------+-------------------------------------------+
| host           | user | password                                  |
+--------------+------+-------------------------------------------+
| localhost    | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
| %               | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
+--------------+------+-------------------------------------------+
3 rows in set (0.00 sec)

這樣機器就可以以用戶名root密碼root遠程訪問該機器上的MySql.
