Can't restart MySQL caused by InnoDB - mysql

Question

I can't restart MySQL or recover MySQL from ( InnoDB tables )
I have one WSL using Ubuntu 16.04. By "unknown" accident, at morning i can't access MySQL. Tried to restart it and ... all errors.
Tried with all advice about InnoDB & log* files. But not success.
I did backup /var/lib/mysql and re-install new instance of WSL - Ubuntu 16.04
Tried to recover from physical backup files ( log* & data files & database directory ). But still have same errors.
[Update 1]
Follow this guide: https://dba.stackexchange.com/questions/71596/restoring-mysql-tables-from-ibd-frm-and-mysqllogbin-files
I have re-installed another WSL
Follow guide to restore db from .frm & .idb
Everything goes well until IMPORT TABLESPACE.
MySQL keep saying :
ERROR 1812 (HY000): Tablespace is missing for table `dbname`.`table`

Answer 1

For [ERROR] InnoDB: Linux Native AIO interface is not supported on this platform. Please check your OS documentation and install appropriate binary of InnoDB.:
Solution: Add the following lines at /etc/mysql/my.cnf
[mysqld]
innodb_use_native_aio = 0
For [ERROR] InnoDB: Ignoring the redo log due to missing MLOG_CHECKPOINT between the checkpoint 92858715 and the end 92858687.:
Solution: Delete the ib_logfiles from /var/lib/mysql
sudo rm -rf /var/lib/mysql/ib_logfile*

Answer 2

I had a similar problem. I was using MySQL in docker but this solution is same for both. You need to remove ib_logfiles
If you are not using docker then
rm -rf /var/lib/mysql/ib_logfile*
And if you using docker then
cd /your_mount_path/
then run
rm -rf * ib_logfile*
Note: Make sure you make a backup of the data or volume as I ended up losing my data.

Answer 3

if anyone's ended up here struggling with wix-embedded-mysql and for some reason can't change the mysql settings in your WSL distro or host unix system, you can just disable it through the custom mysqld setting .withServerVariable like:
.withServerVariable("innodb_use_native_aio", 0)
That option's only doable if you really don't care about InnoDB usage in your code though.
