Question

我已经花了一天的时间挠头，可能读了很多文章，以及如何允许我的MariaDB监听远程连接。不幸出现以下错误。

Host 'xxx.xxx.xxx.xxx' is not allowed to connect to this MariaDB server.

我还阅读了StackOverflow question，anotherQuestion，并能够成功创建新用户并通过以下MySQL查询授予所有权限。

CREATE USER 'ahsensaeed'@'%' IDENTIFIED BY 'my_password';
GRANT ALL PRIVILEGES ON *. TO 'ahsensaeed'@'%' WITH GRANT OPTION;

以下是我的被感动的用户资助。

MariaDB [mysql]> show grants for 'ahsensaeed'@'%';
+--------------------------------------------------------------------------------------------------------------------------------------+
| Grants for ahsensaeed@%                                                                                                              |
+--------------------------------------------------------------------------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'ahsensaeed'@'%' IDENTIFIED BY PASSWORD '*F794ABE2A12665587C6B6D8B61E2F7E987711AFA' WITH GRANT OPTION |
+--------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

最后，我只是清空特权，然后，转到我的MariaDB配置文件并对其进行编辑。下面是我的MariaDB conf文件放置的路径。

/etc/mysql/mariadb.conf.d/50-server.cnf

下面显示了我的MariaDB文件块。

[mysqld]

#
# * Basic Settings
#
user        = mysql
pid-file    = /var/run/mysqld/mysqld.pid
socket      = /var/run/mysqld/mysqld.sock
port        = 3306
basedir     = /usr
datadir     = /var/lib/mysql
tmpdir      = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking

# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = 0.0.0.0
.....
.....

，然后我通过/etc/init.d/mysql restart重新启动 mysql 服务。我还在客户端上为 mysql 打开3306端口。

当上述解决方案不起作用时，我还在/etc/mysql/conf.d/mysql.cnf文件中添加了 bind-address = 0.0.0.0 ，但仍然失败，并出现错误。

下面显示了我如何从服务器请求MariaDB数据库。

-> mysql -uahsensaeed -p -h hostIp

然后出现以下错误。

错误1130（HY000）：不允许主机'hostIp'连接到此MariaDB服务器

编辑。添加了主机和用户数据。

MariaDB [(none)]> select User,Host from mysql.user;
+------------+-----------+
| User       | Host      |
+------------+-----------+
| ahsensaeed | %         |
| root       | localhost |
+------------+-----------+
2 rows in set (0.00 sec)

任何帮助将不胜感激。

这对我有用（我使用Ubuntu 18.04作为虚拟机，而Windows 10使用Vagrant）：

sudo mysql -e "CREATE DATABASE {db_name};"
sudo mysql -e "CREATE USER {user_name}@localhost IDENTIFIED BY '{password}';"
sudo mysql -e "UPDATE mysql.user SET Host='%' WHERE User='{user_name}';"
sudo mysql -e "GRANT ALL PRIVILEGES ON {db_name}.* TO '{user_name}'@'%';"
sudo mysql -e "FLUSH PRIVILEGES;"
sudo systemctl restart apache2
sudo systemctl restart mariadb

之后，您应该编辑文件：

/etc/mysql/mariadb.conf.d/50-server.cnf

并将 bind-address 属性设置为您的hostIP地址，或仅对此行进行注释。

最后，运行命令：

sudo systemctl restart apache2
sudo systemctl restart mariadb

我希望这能满足您的需求
