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与%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
将/etc/mysql/mariadb.conf.d/50-server.cnf中bind-address = 127.0.0.1加# 注释掉
三.重启服务
systemctl restart mariadb.service
四.远程链接
mysql -u root -proot -h 192.168.199.240 -D mysql
