mariadb-libs replaced by mysql-community-libs

1.Problem description

        Installing mysql database Error: Dependency detection failed:

[root@tidbserver mysqlrpm]# rpm -ivh mysql-community-libs-8.0.34-1.el7.x86_64.rpm 
Warning: mysql-community-libs-8.0 .34-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, Key ID 3a79bd29: NOKEY
Error: Dependency check failed:
    mariadb- libs replaced by mysql-community-libs-8.0.34-1.el7.x86_64
 

2.Cause of occurrence

        Mariadb belongs to the mysql branch, so there is a conflict when installing libs

[root@tidbserver mysqlrpm]# rpm -qa | grep -E 'mysql|mariadb'
mysql-community-client-plugins-8.0.34-1.el7.x86_64
mariadb-libs-5.5.68-1.el7.x86_64
mysql-community-common-8.0.34-1.el7.x86_64

3.Solution

        Just delete the lib package that adjusts mariadb

 rpm -e mariadb-libs-5.5.68-1.el7.x86_64 --nodeps 

        After executing the installation of mysql-libs, the installation was successful.
