Mysql包跳过[依赖关系问题]

Question

这似乎是一个重复的问题，但我已做了研究，但仍未能找到解决这个问题的办法。

问题：

在我的linux机器上安装mysql服务器时，我会在mysql安装期间收到Error通知。这些错误声明缺少依赖项。

安装输出：

 You could try using --skip-broken to work around the problem

我运行了--skip命令，它只是重复了error部分中的包。

我尝试通过下载yumutils来解决这里问题&删除重复项，但显然没有重复项。

我尝试了这里在路易的第一个答案中的解决方案，以及Ed的第二个答案。两次尝试都没有骰子。

mysql文档(我可以看到)中没有任何东西可以解决这个问题。我一直在遵循mysql的安装过程找到这里。

其他解决方案：

Mysql文档声明您可以下载各个包。我试图通过sudo yum install libstdc++.so.6来解决缺少的依赖项之一。此安装失败，并提供了以下消息：

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package-cleanup --cleandupes时，我被告知没有副本，这与上面的错误是直接矛盾的。

更新：

卸载mysql之后，我重新安装了mysql 7版本。我运行了安装命令，并遇到了同样的问题。输出可以看到这里。

1. 我在这里使用了以下mysql 7版本链接：https://dev.mysql.com/downloads/file/?id=484922 (红帽下载)
2. 我运行了wget https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm
3. 我运行了sudo rpm -ivh mysql80-community-release-el7-3.noarch.rpm.2
4. 我运行了sudo yum install -y mysql-server

第四步是触发所有错误。

解决这个问题的任何帮助都是非常感谢的。

Answer 1

您以某种方式安装了一个用于RHEL/CentOS 8的名为mysql80-community-release的包，但是您的系统是CentOS 7。这个包提供了下载MySQL的存储库，但是它为RHEL/CentOS 8提供了软件包。这在您的系统中是行不通的。

您需要删除此包并将其替换为与CentOS 7等效的包，即用yum remove mysql80-community-release替换它。这样做之后，您需要使用yum clean all清除yum的缓存，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，然后安装CentOS 8的软件包就可以工作了。

Answer 2

我试着做yum remove mysql80-community-release和yum clean all，在包依赖项方面仍然存在同样的问题。我不得不做一个yum clean all --verbose，它向我展示了列在“未跟踪的repos”下的缓存目录：

Disk usage under /var/cache/yum/*/* after cleanup:
0      enabled repos
7.9 M  disabled repos:
  4.8 M  /var/cache/yum/x86_64/7/myorg-elastic-6.x
  3.2 M  /var/cache/yum/x86_64/7/myorg-elastic-7.x
5.3 M  untracked repos:
  3.9 M  /var/cache/yum/x86_64/7/myorg-puppet5
  700 k  /var/cache/yum/x86_64/7/mysql80-community
  376 k  /var/cache/yum/x86_64/7/mysql-connectors-community
  340 k  /var/cache/yum/x86_64/7/mysql-tools-community
4.0 k  other data:
  4.0 k  /var/cache/yum/x86_64/7/timedhosts
13 M   total

我手动删除了/var/cache/yum/x86_64/7/mysql*文件夹，然后尝试了sudo yum install -y mysql-server，这就成功了。
