标签： php mysql linux database centos

【解决方案1】：

尝试更换所有者。

chown -R mysql.mysql /var/lib/mysql

并确保“/var”和“/var/lib”保留其 root.root 所有权和 755 chmod。让我知道它是否能解决您的问题。

编辑：请在 [mysqld] 部分下的“my.cnf”文件中添加以下代码行选项：

ignore-db-dir = lost+found

然后重启mysql服务。

拜托，你能告诉我mysql文件夹里有什么吗？
你用的是哪个mysql版本？
请同时执行以下查询“SHOW DATABASES”并在此处打印结果。
