I know AWS do not support downgrades in the RDS UI or with CLI, however I have been told that I can downgrade from the deprecated MySQL 8.0.29 to 8.0.28 using the AWS Database Migration Service.
I have Googled everywhere but can't find any help on this, and I'm still waiting for Amazon to tell me.
Does anybody know how to do this (step by step instructions would help) or if there is another way?
I have a Ruby On Rails App on Elastic Beanstalk with MySQL RDS, and I want to migrate it to Aurora MySQL, I could migrate my database and I have the new endpoint of Aurora MySQL, I first tried to connect it in my development environment to check if everything was going good, but when I try to deploy in production I got an error by elastic beanstalk "12_db_migration.sh failed.", but It does not have sense because I connected the database in development and It worked, It looks like if elastic beanstalk couldn't connect to the database, all credentials are correct. There are not pending migrations, and the error message does not have sense. Something important is that my previous MySQL version is 5.7.24 and the MySQL version of my new Aurora MySQL database is 5.7.12, but I think It doesn't matter because in development worked well.
Thank you.
okay, I could fix it, the problem was that I was written my credentials in database.yml file without using environment variables, I was testing something and I didn't use environment variables, and It looks that I cannot do that, I use environment variables in the file and everything worked.
I want to implement data synchronization for my local db to elastic search. I found Scrutineer can do the job. But there is enough documentation for installation and running. How I can run it with mysql configuration?
I am wondering if there is anyone try to use mysql workbench to connect to openedx fullstack version. I have a devstack version which is running on my local machine and doesn't have any issues. Also, I am able to connect to mysql database by using SSH on mysql workbench(devstack).
Please see the official document here: https://github.com/edx/edx-platform/wiki/Developing-on-the-edX-Developer-Stack#the-edx-platform-database-that-devstack-uses
But I am not able to find any document regrading the process of fullstack mysql connection configuration.
Any ideas or suggestions? Appreciate your help!
I need to upgrade mysql 5.0 to mysql 5.6 on Linux Server . What are the commands or what are the steps should I follow . I am new to mySQL and Linux. I have gone through the steps to follow but I could not get any complete idea like how to get the software copied to Linux and what are the mysql commands on Linux to upgrade the existing mysql.
Check the Official Documentation on MySql for the instructions to Upgrade your MySql server.
As #Michael said, It heavily depends on your Linux distro. Generally you can upgrade using Yum Repository/Apt Repository via Terminal. You may refer to the documentation for more information.
