Percona XtraDB wont install due to conflict with MariaDB in CentOS 7

In this case, i want to install Percona XtraDB Cluster 5.7 to replace MariaDB 10.7 on my CentOS 7 VPS.

First i have to remove mariadb 10.7

yum remove mysql
rm -rf /var/lib/mysql

yum remove mysql

Complete!

Uninstall process was completed and I'm going to install Percona XtraDB Cluster 5.7.

All i have to do is install percona-release first, and install percona

# Setup repository
sudo yum install https://repo.percona.com/yum/percona-release-latest.noarch.rpm

# Turns a release on
sudo percona-release enable pxc-57 release

# Setup Percona XtraDB Cluster 5.7
sudo percona-release setup -y pxc-57

# Enabling the Percona XtraDB Cluster 5.7 repository
# Enabling the Percona XtraBackup 2.4 repository

sudo yum install -y Percona-XtraDB-Cluster-57

Transaction check error:
  file /etc/my.cnf from install of Percona-XtraDB-Cluster-server-57-5.7.37-31.57.1.el7.x86_64 conflicts with file from package MariaDB-common-10.7.3-1.el7.centos.x86_64
  file /usr/lib64/mysql/plugin/dialog.so from install of Percona-XtraDB-Cluster-server-57-5.7.37-31.57.1.el7.x86_64 conflicts with file from package MariaDB-common-10.7.3-1.el7.centos.x86_64

But the installation was not completed, looks like mariadb package still there and it conflict with Percona XtraDB package (or like any mysql variant).

Solution :

Remove completely mariadb first by using this command :

yum remove mariadb-libs

and try reinstall percona-xtradb-cluster-57 again.

yum install Percona-XtraDB-Cluster-57

I got this solution from stackoverflow.

Thanks
