我已经尝试了我在互联网上找到的所有内容，但我遇到了同样的错误.我也尝试创建新用户，但我尝试授予的每个用户仍然遇到相同的错误.
I have tried all what I found on the internet, but I've got the same error. I also tried creating new user, but I still got same error on every user I try to grant on.
有人可以帮我解决这个问题吗?
Does anybody could help me to resolve this problem?
提前致谢.
推荐答案
首先我会检查数据库服务器是否正在监听网络.
First of all i would check if the database server is listening on the network.
netstat -tlpn | grep mysql
我希望是这样的:
tcp 0 127.0.0.1:3306 0.0.0.0:* LISTEN
如果数据库服务器正在侦听 127.0.0.1:3306，则仅允许从 localhost 进行连接.更改50-server.cnf中的以下行并重新启动数据库服务(service mariadb restart).
If the database server is listening on 127.0.0.1:3306, connection are allowed only from localhost.
Change the following lines in 50-server.cnf and restart the database service (service mariadb restart).
bind-address = 0.0.0.0
- 使用
bind-address 允许监听多个网络接口或特定 IP 地址
- Permit listening on multiple network interfaces or a specific IP address with
bind-address
您的 mysql.user 表显示用户 root 只能从 localhost 和 127.0.0.1 连接.
Your mysql.user tables shows that user root can connect only from localhost and 127.0.0.1.
如果您需要一个可以从任何地方连接到数据库的远程用户(@'%')，具有 root 权限，您可以创建另一个超级用户.
If you need a remote user, that can connect to database from everywhere (@'%'), with root privileges, you can create another superuser.
GRANT ALL PRIVILEGES ON *.* TO 'superuser'@'%' IDENTIFIED BY 'use_a_secure_password';
现在超级用户拥有与默认 root 帐户相同的权限，请注意！
Now superuser has the same privileges as the default root account, beware!
作为对用户权限进行任何更新后的最后一步:
As a final step following any updates to the user privileges:
FLUSH PRIVILEGES;
我还注意到您的 mysql.user 表显示了一个可以通过网络连接的用户 ruser.
Also i notice that your mysql.user tables shows a user ruser that can connect over the network.
