mysql/MariaDB 搭建后创建密码及开启远程

Posted 2020-11-09 Nage

创建密码：

mysqladmin -u root -p password newpassword

或

MariaDB [(none)]> use mysql
MariaDB [mysql]> update user set password=password("123456")where user=‘root‘;
Query OK, 0 rows affected (0.00 sec)
Rows matched: 4 Changed: 0 Warnings: 0
MariaDB [mysql]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

开启远程服务：

   查看user表：可以发现表中没有开启远程的服务 %    root

mysql> use mysql;
Database changed
mysql> select host,user,password from user;
+--------------+------+-------------------------------------------+
| host         | user | password                                  |
+--------------+------+-------------------------------------------+
| localhost    | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
| 127.0.0.1    | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
+--------------+------+-------------------------------------------+
2 rows in set (0.00 sec)

实现远程连接(授权法)：

将host字段的值改为%就表示在任何客户端机器上能以root用户登录到mysql服务器，建议在开发时设为%。   
update user set host = ’%’ where user = ’root’;                                    将权限改为ALL PRIVILEGES

 

mysql> use mysql;
Database changed
mysql> grant all privileges on *.* to [email protected]‘%‘ identified by "password";
Query OK, 0 rows affected (0.00 sec)
MariaDB [mysql]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> select host,user,password from user;
+-----------+------+-------------------------------------------+
| host      | user | password                                  |
+-----------+------+-------------------------------------------+
| localhost | root | *23AE809DDACAF96AF0FD78ED04B6A265E05AA257 |
| 127.0.0.1 | root | *23AE809DDACAF96AF0FD78ED04B6A265E05AA257 |
| ::1       | root | *23AE809DDACAF96AF0FD78ED04B6A265E05AA257 |
| localhost |      |                                           |
| %         | root | *23AE809DDACAF96AF0FD78ED04B6A265E05AA257 |
+-----------+------+-------------------------------------------+
5 rows in set (0.00 sec)

这样机器就可以以用户名root密码远程访问该机器上的MySql.
