Question

我刚刚在Centos 7中安装了MariaDB 10.3数据库服务器。

一切顺利，但是执行“ systemctl status mariadb”命令时。这是完整的输出：

root@vps [/etc/init.d]# systemctl status mariadb
● mariadb.service - MariaDB 10.3.13 database server

数据库已启动，但是，我想解决那里的错误。例如，表中缺少列的问题或对admin @ localhost用户的访问权限。

为了尝试解决管理员用户问题，我已经创建了该用户并授予了所有特权，但是它仍然显示该错误。

任何帮助将不胜感激。

看起来好像已经进行了先前的安装，运行mysql_upgrade工具应该可以修复系统表，并使其与您现在安装的版本的结构正确。
