根据您提供的日志信息，MySQL启动失败并显示了一系列错误消息。根据错误消息，这可能是由于InnoDB日志格式不受支持导致的。这可能是由于您尝试将之前版本的数据目录与当前安装的MySQL版本一起使用。

为了解决这个问题，您可以尝试以下步骤：

1. 备份数据目录：在继续之前，请确保先备份MySQL的数据目录，以防止数据丢失。

2. 清除数据目录：停止MySQL服务后，删除数据目录中的所有文件和子目录。默认情况下，数据目录通常位于/var/lib/mysql。

3. 重新初始化数据目录：使用以下命令重新初始化数据目录：

sudo mysqld --initialize-insecure

这将重新创建并初始化一个空的数据目录。

4. 启动MySQL服务器：使用以下命令启动MySQL服务器：

sudo systemctl start mysqld

检查MySQL服务器的状态以确保它已成功启动：

sudo systemctl status mysqld

如果上述步骤无法解决问题，您可能需要考虑完全卸载MySQL并重新安装。在重新安装之前，请确保删除所有与MySQL相关的文件和目录，并备份重要的数据。

请注意，执行这些操作可能会导致数据丢失，请确保在执行任何操作之前进行适当的备份。如果您对MySQL安装和配置不确定，建议寻求专业人士的帮助或参考MySQL官方文档。
