MySQL service will not stay running - Master/Slave error?

Postby kj2757 » 01. September 2020 16:03

Hello Everyone,
I am attempting to troubleshoot a problem whereby Omeka is unable to connect to the underlying database by way of XAmpp:

Omeka Database Error
No connection could be made because the target machine actively refused it.
Confirm that the information in your db.ini file is correct.


Everything is installed on a Windows 2012R2 server. Using the XAmpp Control Panel (v 3.2.4), I attempt to start the MySQL service which is off and after a few moments, the service stops by itself. Looking at mysql_error.log, I see the following error entries:

2020-08-05 15:55:07 7 [Warning] Neither --relay-log nor --relay-log-index were used; so replication may break when this MySQL server acts as a slave and has his hostname changed!! Please use '--log-basename=#' or '--relay-log=mysql-relay-bin' to avoid this problem.
2020-08-05 15:55:07 7 [ERROR] log 2020-08-05 13:27:58 7 [Note] Initialized Master_info from 'master-2020@002d07@002d27@002012@003a01@003a12@00200@0020@005bnote@005d@0020reading@0020of@0020all@0020master_info@0020entries@0020succeeded@000d.info'
listed in the index, but failed to stat
2020-08-05 15:55:07 7 [ERROR] Error counting relay log space
2020-08-05 15:55:07 7 [ERROR] Initialized Master_info from 'master-2020@002d07@002d27@002012@003a01@003a12@00200@0020@005bnote@005d@0020reading@0020of@0020all@0020master_info@0020entries@0020succeeded@000d.info' failed
...


I tried to overlay the following files with corresponding original ones:

aria_log.00000001
aria_log_control
ibdata1
ibtmp1
ib_buffer_pool
ib_logfile0
ib_logfile1
multi-master.info
my.ini

and re-start the MySQL service. The service did re-start and stayed running. However errors were being generated in the log and Omeka seemed to think at that point that the database instance was brand new:

2020-08-18 11:45:10 0 [ERROR] InnoDB: Page [page id: space=0, page number=7] log sequence number 288046 is in the future! Current system log sequence number 140309.
2020-08-18 11:45:10 0 [ERROR] InnoDB: Your database may be corrupt or you may have copied the InnoDB tablespace but not the InnoDB log files. Please refer to https://mariadb.com/kb/en/library/innodb-recovery-modes/ for information about forcing recovery.
...


So I restored the files back to the current ones and again the MySQL service would not remain running more than a few seconds:

Please let me know if I need to provide more info to help with this issue. I would greatly appreciate any pointers or tips to help with getting our database back up and serving the installed Omeka instance.

Best Regards
