Mat*_*hew 2 mysql installation centos
这可能看起来像一个重复的问题，但我已经完成了我的研究，但仍然无法找到这个问题的解决方案。
问题：
在我的 Linux 机器上安装 mysql 服务器时，我Error在 mysql 安装过程中收到通知。这些错误表明缺少依赖项。
安装输出：

You could try using --skip-broken to work around the problem
我运行了该--skip命令，它只是重复了该部分中的包error。
我尝试通过下载 yumutils 并删除重复项来解决此问题，但显然没有重复项。
我在路易斯的第一个答案以及埃德·莫克斯利的第二个答案中尝试了解决方案。两次尝试都没有骰子。
mysql 文档（我可以看到）中没有任何内容可以解决这个问题。我一直在关注 mysql 的安装过程，在这里找到了。
其他解决方案：
Mysql 文档指出您可以下载单独的包。我尝试通过 解决缺少的依赖项之一sudo yum install libstdc++.so.6。此安装失败，并提供以下消息：
Error: Multilib version problems found. This often means that the root
cause is something else and multilib version checking is just
pointing out that there is a problem. Eg.:
1. You have an upgrade for libstdc++ which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of libstdc++ of the
different architecture. If you exclude the bad architecture
yum will tell you what the root cause is (which package
requires what). You can try redoing the upgrade with
--exclude libstdc++.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of libstdc++ installed, but
yum can only see an upgrade for one of those architectures.
If you don't want/need both architectures anymore then you
can remove the one with the missing update and everything
will work.
3. You have duplicate versions of libstdc++ installed already.
You can use "yum check" to get yum show these errors.
...you can also use --setopt=protected_multilib=false to remove
this checking, however this is almost never the correct thing to
do as something else is very likely to go wrong (often causing
much more problems).
当我尝试运行时，package-cleanup --cleandupes我被告知没有重复项，这与上述错误直接矛盾......
更新：
卸载mysql后，我重新安装了mysql centos 7版本。我运行了安装命令并遇到了同样的问题。可以在此处查看输出。
wget https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpmsudo rpm -ivh mysql80-community-release-el7-3.noarch.rpm.2sudo yum install -y mysql-server第四步是触发所有错误。
非常感谢解决此问题的任何帮助。
您以某种方式安装了一个名为 RHEL/CentOS 8 的软件包mysql80-community-release，但您的系统是 CentOS 7。该软件包提供了下载 MySQL 的存储库，但它提供了适用于 RHEL/CentOS 8 的软件包。这在您的系统上不起作用。
您需要删除此软件包并将其替换为 CentOS 7 的等效软件包，即yum remove mysql80-community-release. 执行此操作后，您需要使用 清除 yum 的缓存yum clean all，然后您可以安装正确的发行包并再次尝试安装。
或者，您可以升级到 CentOS 8，然后即可安装 CentOS 8 的软件包。
