我正在尝试安装mysqlgovernor，最后我得到了这个烂摊子，现在我的所有网站都关闭了。

这是我的错误列表：
InnoDB：文件buf0buf.cc第2850行中的主题140010623854336中的断言失败
以下是重新安装后正在运行的MariaDB，并禁用InnoDB数据库，但我们不想没有它们。

答案 0 :(得分：0)
请查看错误日志的前三行： MariaDB无权写入panel.uhlhosting.ch.err所在的目录
您可以通过将此目录的所有者/组更改为mysql：mysql chown -R mysql:mysql /path/to/directory/（如果它位于Linux上）来解决此问题。
