Re: Unsupported redo log format

I did that - thanks. I have 5.6 installed.

Now I'm getting:

2020-02-24 13:39:04 9260 [Note] InnoDB: Completed initialization of buffer pool
2020-02-24 13:39:04 9260 [ERROR] InnoDB: auto-extending data file ./ibdata1 is of a different size 640 pages (rounded down to MB) than specified in the .cnf file: initial 768 pages, max 0 (relevant if non-zero) pages!
2020-02-24 13:39:04 9260 [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!
2020-02-24 13:39:04 9260 [ERROR] Plugin 'InnoDB' init function returned error.
2020-02-24 13:39:04 9260 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
2020-02-24 13:39:04 9260 [ERROR] Unknown/unsupported storage engine: InnoDB
2020-02-24 13:39:04 9260 [ERROR] Aborting

I've seen this one before, and it's always proven fixable by adding

innodb_data_file_path = ibdata1:18M:autoextend

in /etc/my.cnf .

This isn't working now - I'm not entirely certain mysqld is even looking at /etc/my.cnf , as nothing I do with that file appears to affect it.

Once again, any help you can offer will be greatly appreciated.
