升级mysql后服务器无法启动？
升级
apt update && apt upgrade
8.0.35=>8.0.36
操作系统：Debian bookworm
错误
Tablespace 123588, name 'sys/sys_config', file './sys/sys_config.ibd' is missing!
在 datadir 中没有名为 的目录sys。
datadir 文件夹中的目录
#innodb_redo
#innodb_temp
database1
database2
mysql
我有几个服务器正在运行mysql 8.0.35，但没有一个sys在 datadir 中有文件夹
大约一年前我从升级mysql 5.7到mysql 8.0
