Percona安装失败

Question

在安装percona服务器这么多次之后，没有问题，我似乎碰到了一个唯一的服务器。

# yum list installed | grep -i perc
percona-release.noarch               0.1-10                           @percona-release-noarch

如你所见，我只安装了回购工具。当我安装PXC5.7时，我得到以下内容：

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

运行建议的命令不会产生任何结果。我尝试过安装PXC56，它工作得很好。然后，我对这些包进行yum remove处理，然后再试一次，得到相同的结果。我还试着安装它提到的与之冲突的特定包

yum install https://repo.percona.com/centos/7/RPMS/x86_64/Percona-Server-shared-56-5.6.42-rel84.2.el7.x86_64.rpm

它将安装良好，yum删除工作，尝试安装PXC57，得到同样的冲突。我甚至尝试过用rpm -e和yum来删除它。我从来没遇到过这样的问题。

更新：

我已经把它缩小到了perl-DBD-MySQL是问题包。

但还是不知道怎么解决

Answer 1

不幸的是，您在这里遇到了一个已知的问题，您是对的，这与perl-DBD-MySQL包有关。

您应该能够通过运行以下命令来补救这一问题

yum install perl-DBD-MySQL

之后，安装Percona包，然后您可以安装Percona XtraDB集群，Percona for MySQL
