 You could try using --skip-broken to work around the problem
** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows:
rdma-core-devel-51mlnx1-1.51066.x86_64 has missing requires of ibacm(x86-64) = ('0', '51mlnx1', '1.51066')

reason

Because there is no MySQL source, you will be prompted to install mariadb-devel-5.5.50-1.el7 when installing MySQL devel_ 2.x86_ 64, and the system does not have mysql_ config

Solution

wget http://repo.mysql.com/mysql57-community-release-el7-10.noarch.rpm
rpm -ivh mysql57-community-release-el7-10.noarch.rpm
ls /etc/yum.repos.d/

The installation source appears

[root@VM-0-17-centos software]# ls /etc/yum.repos.d/
CentOS-Base.repo  CentOS-Epel.repo  CentOS-SCLo-scl.repo  CentOS-SCLo-scl-rh.repo  mysql-community.repo  mysql-community-source.repo

Continue to complete the installation

yum install mysql-devel
