尝试了几个小时才能安装mysql，但由于冲突而失败。
这是一个全新安装的CentOS 8 x64（最新版本），并且已完全更新。 没有安装自定义软件包，这是最小安装。
这是在功能相对强大的专用服务器上，上面没有其他任何东西。
我首先遇到了尝试安装CentOS Web Panel的问题。 在安装和更新之后，这是我在该服务器上所做的唯一一件事。 centos Web面板的失败与我在mysql中遇到的冲突完全相同。 Mysql失败，因为它说已安装mariadb。 但是，即使我删除了mariadb，它仍然会出现相同的问题。
当我尝试直接安装mysql时，也会发生同样的问题。 我能够毫无问题地安装mariadb，甚至也可以将其删除。 但是仍然在安装和删除mariadb之后，由于不存在冲突，mysql仍然拒绝。

# yum remove mariadb-libs -y No match for argument: mariadb-libs No packages marked for removal. Dependencies resolved. Nothing to do. Complete! 因此，与另一个提出该问题的问题不同，删除maria-libs不是解决方案。
还尝试删除任何无关的文件/文件夹。
rm -f /var/log/mariadb rm -f /var/log/mariadb/mariadb.log.rpmsave rm -rf /var/lib/mysql rm -rf /usr/lib64/mysql rm -rf /usr/share/mysql 没运气。 即使它不存在并且未安装，也存在同样的错误。
最后尝试：尝试重新安装mariadb进行安装也失败
最后，我尝试了另一件事，就是完成所有这些之后，然后尝试安装mariadb ，然后尝试安装mysql，
~# yum install mariadb -y Last metadata expiration check: 0:02:02 ago on Sat 23 Nov 2019 02:51:37 PM EST. Dependencies resolved. ... Installed: mariadb-3:10.3.11-2.module_el8.0.0+35+6f2527ed.x86_64 mariadb-common-3:10.3.11-2.module_el8.0.0+35+6f2527ed.x86_64 mariadb-connector-c-3.0.7-1.el8.x86_64 MariaDB-common-10.1.43-1.el7.centos.x86_64 Complete! 而且mariadb可以很好地安装，但是mysql仍然没有安装。 它给出了一个不同的错误，但这是因为在这种情况下安装了mariadb。 如果我再次删除mariadb，则会再次出现上述原始错误。
