问题描述
我正在尝试在虚拟机上运行MySql。但是，我遇到以下错误，因此MySql无法启动。我是MySql的新手。非常感谢您的帮助！这是错误日志中的消息：
[Note] Plugin 'FEDERATED' is disabled.

[ERROR] InnoDB: space header page consists of zero bytes in data file ./ibdata1
[ERROR] InnoDB: Could not open or create the system tablespace. If you tried to add new data files to the system tablespace,and it failed here,you should now edit innodb_data_file_path in my.cnf back to what it was,and remove the new ibdata files InnoDB created in this failed attempt. InnoDB only wrote those files full of zeros,but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!
[ERROR] Plugin 'InnoDB' init function returned error.
[ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
[ERROR] Unknown/unsupported storage engine: InnoDB
[ERROR] Aborting

如果您仔细阅读，第一行会启发您解决问题，第二行会为您提供解决方案。
运行mysql_upgrade进行修复。
似乎，您没有设置ibdata1的路径或删除了ibdata1文件。请检查my.cnf并在my.cnf中设置以下参数。
-
innodb_data_home_dir （innodb的路径）
-
innodb_data_file_path （例如：ibdata1：10M：autoextend）
注意：如果是新设置，请同时启用 innodb_file_per_table
