尝试在cent os 6上安装mysql 8.0时出现问题。 来自“ uname -a”的输出

Linux instance-1 2.6.32-754.24.3.el6.x86_64 #1 SMP Thu Nov 14 15:35:16 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

下一步是我要尝试的步骤：

• $ wget http://dev.mysql.com/get/mysql80-community-release-el6-3.noarch.rpm
• $ sudo yum localinstall mysql80-community-release-el6-3.noarch.rpm
• $ sudo yum安装mysql-community-server

结果是有此输出，似乎它试图从el7安装。

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

注意：在尝试以相同的步骤安装el7版本之前，似乎根本无法删除它。 问：如何从系统中删除el7版本并为cent os 6正确安装mysql 8.0？
