Mariadb设置允许远程链接

一. 修改数据表

1.进入 mariadb

mysql -u root -p

2.修改表

MariaDB [mysql]> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root';
Query OK, 0 rows affected (0.00 sec)
  • 第一个位置,为数据库, 第二个位置,为表,所以 *.*,表示可以访问任意数据的任意表
  • 'root'@'%', root表示远端登录使用的用户名,%表示允许任意ip登录,可将指定ip替换掉%, root%可以自定义
  • IDENTIFIED BY 'root' 这个root 是登录时的使用的密码,(方便记忆就用了root,生产环境一定要替换掉)

3.查看修改后

MariaDB [mysql]> SELECT host,user,password from user;
+-----------+------+-------------------------------------------+
| host      | user | password                                  |
+-----------+------+-------------------------------------------+
| localhost | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| %         | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
+-----------+------+-------------------------------------------+
2 rows in set (0.00 sec)
  • | % | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |表示修改成功

二. 修改配置文件

/etc/mysql/mariadb.conf.d/50-server.cnfbind-address = 127.0.0.1# 注释掉

三.重启服务

 systemctl restart mariadb.service

四.远程链接
