Answer 1

请检查innodb_force_recovery，将其设置为1并启动mysql。有关更多详细信息，请阅读： enter link description here

Answer 2

此错误表示数据库数据已损坏。您可以尝试以恢复模式启动mysql实例，如果幸运的话，将能够进行备份。取决于所选模式表是只读的

警告：在恢复模式下启动服务之前，请备份数据文件

要以恢复模式启动mysql，请在您的mysql启动参数中添加--innodb_force_recovery=<mode>

mysql支持从0到6的值 Mysql recovery docs

docker-compose文件示例：

version: '2'
services:
  myservice-mysql:
    image: mysql:8.0.17
    volumes:
      - ~/volumes/MyProject/mysql/:/var/lib/mysql/
    environment:
      - MYSQL_USER=root
      - MYSQL_ALLOW_EMPTY_PASSWORD=yes
      - MYSQL_DATABASE=MyProject
    ports:
      - 3306:3306
    command: mysqld --innodb_force_recovery=6 --lower_case_table_names=1 --skip-ssl --character_set_server=utf8mb4 --explicit_defaults_for_timestamp

如果mysql成功启动，则可以使用任何工具进行转储，可以在新的未损坏的mysql实例上还原
