How to uninstall MariaDB and re-install MySQL? MySQL install turns into MariaDB install
Solution 1
You still have the MariaDB yum repository on your system. As long as you do so, MariaDB will continue to replace MySQL.
To resolve the issue, remove the MariaDB repository. Do this by locating the file (it may be named something like mariadb.repo
) in the /etc/yum.repos.d
directory. Once you locate the file, you may remove it, or you may edit the file and change enabled=1
to enabled=0
.
Solution 2
If you must have mysql you need to add the mysql-community repo sudo rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
and then you can install MySQLl like you normally do.

I recently upgraded my CentOS system via the desktop. Mistake!
I had MariaDB, phpMyAdmin working just fine before - but after the upgrade they stopped.
I frantically googled and tried to follow some tutorials about MariaDB MySQL reinstall until I came to this one:
I executed this command to remove all of MySQL:
yum remove mysql-server mysql-libs mysql-devel mysql*
and then tried to reinstall MySQL:
as below - it crashes with errors as follows:
***************************************************************** [root@localhost ~]# yum install mysql-server mysql mysql-devel ***************************************************************** Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: centos.serverspace.co.uk * extras: centos.serverspace.co.uk * rpmforge: www.mirrorservice.org * updates: mirror.rmg.io Setting up Install Process Package mysql-server is obsoleted by MariaDB-server, trying to install MariaDB-server-5.5.29-1.i686 instead Package mysql is obsoleted by MariaDB-server, trying to install MariaDB-server-5.5.29-1.i686 instead Package mysql-devel is obsoleted by MariaDB-devel, trying to install MariaDB-devel-5.5.29-1.i686 instead Resolving Dependencies --> Running transaction check ---> Package MariaDB-devel.i686 0:5.5.29-1 set to be updated --> Processing Dependency: MariaDB-common for package: MariaDB-devel ---> Package MariaDB-server.i686 0:5.5.29-1 set to be updated --> Processing Dependency: libssl.so.10 for package: MariaDB-server --> Processing Dependency: libcrypto.so.10 for package: MariaDB-server --> Running transaction check ---> Package MariaDB-common.i686 0:5.5.29-1 set to be updated --> Processing Dependency: MariaDB-compat for package: MariaDB-common ---> Package MariaDB-server.i686 0:5.5.29-1 set to be updated --> Processing Dependency: libssl.so.10 for package: MariaDB-server --> Processing Dependency: libcrypto.so.10 for package: MariaDB-server --> Running transaction check ---> Package MariaDB-compat.i686 0:5.5.29-1 set to be updated ---> Package MariaDB-server.i686 0:5.5.29-1 set to be updated --> Processing Dependency: libssl.so.10 for package: MariaDB-server --> Processing Dependency: libcrypto.so.10 for package: MariaDB-server --> Finished Dependency Resolution MariaDB-server-5.5.29-1.i686 from mariadb has depsolving problems --> Missing Dependency: libcrypto.so.10 is needed by package MariaDB-server-5.5.29-1.i686 (mariadb) MariaDB-server-5.5.29-1.i686 from mariadb has depsolving problems --> Missing Dependency: libssl.so.10 is needed by package MariaDB-server-5.5.29-1.i686 (mariadb) Error: Missing Dependency: libcrypto.so.10 is needed by package MariaDB-server-5.5.29-1.i686 (mariadb) Error: Missing Dependency: libssl.so.10 is needed by package MariaDB-server-5.5.29-1.i686 (mariadb) You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest [root@localhost ~]
If I now try to install libssl.10, I get asked to install glibc libraries. 2.17 and 2.7.
Other discussions have said to stay clear of them as this will explode my system. I tried download 2.17 and it's huge - took ages to unzip.Could someone please help me to completely remove MariaDB and install MySQL - so that I don't get the above errors and pushed over to MariaDB when I run:
yum install mysql-server mysql mysql-devel
There are tons of material on how to install MariaDB - but none I found so far that plainly explains how to go backwards to MySQL.
