【中文标题】由于 mariadb 安装，Mysql 将无法安装但 mariadb 未安装【英文标题】：Mysql will not install due to mariadb install but mariadb is not installed 【发布时间】：2020-03-19 13:07:32 【问题描述】：已经尝试了几个小时来安装 mysql，但由于冲突而失败。
这是全新安装的 CentOS 8 x64（最新），并且已全面更新。没有安装自定义包，这是一个最小安装。
这是在一个相对强大的专用服务器上，上面没有其他任何东西。
我第一次在尝试安装 CentOS Web Panel 时遇到了这个问题。这是我在安装和更新后在这台服务器上所做的唯一事情。 centos web 面板的失败与我与 mysql 遇到的冲突相同。 Mysql 失败，因为它说 mariadb 已安装。但即使我删除了 mariadb，它仍然给出了同样的问题。
当我尝试直接安装 mysql 时会发生同样的问题，这就是这个问题的意义所在。我可以毫无问题地安装 mariadb，甚至可以将其删除。但是在安装和删除mariadb之后，由于不存在冲突，mysql仍然拒绝。

另外没有安装 mariadb-libs。
# 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 并不是解决方案。
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
运气不好。即使它不存在且未安装，也存在相同的错误。
最后一次尝试：尝试在重新安装 mariadb 的情况下安装也失败
最后，我又尝试了一件事，就是做完这一切之后，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.

并且 mariadb 安装正常，但 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，它会再次像上面一样给出原始错误。
# yum install mysql -y

请帮我解决这个问题，谢谢。
【问题讨论】：
一开始似乎很明显。您尝试安装 mysql 而 yum 想要同时安装 mysql-common 和 MariaDB-common，这对我来说听起来像是一个打包问题。为什么不直接使用玛丽亚？无论如何，这不是一个编程问题，并且对于 SO 来说是题外话。请改用Server Fault 或Super User。 不幸的是，这不是答案。 Centos 网络面板想要同时安装两者，所以这样做显然没有任何问题，所以不幸的是，你是不正确的，因为这不是问题的解决方案。 【参考方案1】：我怀疑您遇到了由 MariaDB 错误导致的问题，当 fts 表具有 FK 关系时，InnoDB 无法启动，如下所述：MDEV-20987
为了快速解决此问题，解决此问题的唯一方法是降级安装。使用以下命令进行降级。
yum downgrade MariaDB-server MariaDB-common MariaDB-shared MariaDB-client MariaDB-compat MariaDB-devel
注意： MariaDB 已在以下未发布版本中正式修复了该问题：
10.1.43 [ 23703 ]
10.2.29 [ 23911 ]
10.3.20 [ 23909 ]
10.4.10 [ 23907 ]
【讨论】：
【参考方案2】：尝试安装 mysql-server，而不是使用：yum install mysql-server
【讨论】：
刚试了一下，还是一样的错误。用输出更新了我的问题。以上是关于由于 mariadb 安装，Mysql 将无法安装但 mariadb 未安装的主要内容，如果未能解决你的问题，请参考以下文章
centos通过yum安装mariadb（mysql)无法启动服务或者找不到mysql.sock
