CentOS 7.2 + Ambari 2.6.1.3 + HDP 2.6.4, got MySQL install error, package conflict

[#1]

resource_management.core.exceptions.ExecutionFailed: Execution of '/usr/bin/yum -d 0 -e 0 -y install mysql-community-release' returned 1. Error: Nothing to do

Ambari got the error above.

Try install mysql directly:

[centos@zzeng-hdp-2 ~]$ sudo yum install mysql-community-release
Loaded plugins: fastestmirror

Try MySQL 5.7

[centos@zzeng-hdp-2 ~]$ sudo rpm -ivh http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

[centos@zzeng-hdp-2 ~]$

This still didn't resolve the problem.

At last, I tried to use MySQL 5.6 ( http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm )

[centos@zzeng-hdp-2 ~]$ sudo yum remove mysql57-community-release
