Is there a way to safely downgrade from MariaDB to MySQL? - mysql

I am running cPanel/WHM with MariaDB, it seems that at least according to their sayings is not possible with their built in system to downgrade this automaticly. What about other ways to do it? Does someone have experience with such downgrades, if so please advice. Running Centos 7.

Is there a way to downgrade mysqlbackup?

I have a client that backed up his data with MEB 4.0.0, so now I need to extract the contents of the image, but because I'm using mysql Enterprise Backup 8.0 I can't since it's not compatible.
Is there a way to downgrade my mysqlbackup? Or maybe upgrade his Image? Right now it's in .MBI so I don't see a way out of this since I can't extract and can't find the older version of the mysqlbackup anywhere.
I'm using Windows 10 btw, any help would be appreciated!
Ok I just found out, there is NO WAY do downgrade or get the installer officialy, but there is sites like archive.org that have the old installer there.
If anyone is having trouble because of this problem I suggest to look there.

MySQL server installation fail
I have already installed visual studio 2017 but got this error every time, even when I install mysql server 5.7 . Anyone know to fix this? Thank you.
Can you give us some more info?
Did you try closing all background apps and checked the firewall?
Did you use the MSI-installer or something else?
Did you run it as administrator?

MySQL standalone or via XAMPP?

This is my first question ever at stackoverflow, hope I make sense out of it. I am starting to learn about databases and also programming these days. So I would want to get some advice on MySQL database. Though it's open source and available for download, Should I install the standalone MySQL GUI version on my laptop (Windows 7 32bit) or should I install XAMPP and then access it through phpMyAdmin ?? My purpose of asking this question is that , for starters..I am learning SQL and querying. And then I would want to learn to create web application using php or JavaEE.
I am completely unaware of these concepts, so I would appreciate if someone can just take few minutes and guide me accordingly.
Thanks !
Regards
and welcome :)
If you're planning on concentrating on PHP more than MySQL, it's a good start to install XAMPP. It's more lightweight and contains both PHP and Mysql. It's better for you to concentrate on learning the basics first, rather than spend time on software components. That's why I would choose XAMPP (or my personal favorite: WAMP Server)
If you'd like to spend a bit more time on database management such as user management, jobs,... it could be interesting to download the Mysql server package from their site.
Also, that package comes with example databases which you can use to learn some SELECT and UPDATE queries. It queries a lot easier that PHPMyAdmin.
If your goal is to use MySQL with self-made applications, get XAMPP and learn some PHP before diving into queries
And then I would want to learn to create web application using php
In this case XAMPP should be your friend. BTW with XAMPP you get an MySQL-Server which is identically with the MySQL standalone. You can fire your querys by using phpmyadmin, or connect via shell (console) or thridparty programms ....
In case that you are using NPM, you can install a standalone version of MySQL using the mysql-server package: https://www.npmjs.com/package/mysql-server

Installing and Maintaining Percona Server in an WHM/CPanel Environment

I have a VPS with Liquidweb, which currently uses a standard LAMP stack. I want to replace/supplement the installed version of MySQL with Percona, specifically to leverage XtraDB's advanced features. My initial request to their SysAdmins was they don't support that since its a nonstandard install.
My question is has anyone successfully run Percona in a WHM/Cpanel controlled environment? How did you install Percona? Did you have any problems? How do you maintain that installation? Were you able to have WHM "automatically" upgrade Percona, or at least prevent it from upgrading Percona down to MySQL? Is there a better way?
As a background, I am a software developer. I can run make, but managing a secure DB installation is beyond my scope.

The install is pretty straight forward. The database upgrading will not be managed within WHM/cpanel, so you would need to use your own method to administer updates. You should be able to install Maria in about the same matter.
I would personally keep a close eye on the installed database when cpanel does an update, just to make sure that it doesn't do something crazy like kicking the Percona version out. But, it should work without too much fuss.

Which mysql server package should I install?

I posted this question on serverfault but have not received an answer. Maybe someone here can answer this:
I just switched hosts and now have the task of reinstalling everything. I'm on CentOS now and I need to install mysql but have no idea which package to install. I can't seem to find any info on the differences either. Would anyone know? Yum is not an option as it wants to install 5.0.77 and this is too old. The machine is 64 bit.
5.0 is not supported anymore (unless you have a contract). 5.1 is the only GA-version with support, the only option you have for a free MySQL-database with support.
