Percona 安装失败

Question

安装 percona server 这么多次都没有问题之后，我似乎遇到了一个独特的问题。

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

如您所见，我只安装了存储库。当我去安装 PXC5.7 时，我得到这个：

运行建议的命令没有结果。我试过安装 PXC56，它工作正常。然后我 yum remove 这些包并再次尝试只是为了得到完全相同的东西。我也试过安装它提到的与

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

安装正常，yum remove 可以，尝试安装PXC57，同样出现冲突。我什至尝试使用 rpm -e 删除它并使用 yum-utils。我以前从来没有遇到过这个问题。

更新：

我已经缩小到 perl-DBD-MySQL 是问题包。

仍然不知道如何修复

Answer 1

不幸的是，你运行进入了这里的一个已知问题，你是对的，它与 perl-DBD-MySQL 包有关

您应该可以通过运行解决这个问题

yum install perl-DBD-MySQL

之后，安装 Percona repo 包，然后就可以安装 Percona XtraDB Cluster，Percona Server for MySQL

有关更多信息，您可以在 https://jira.percona.com 找到大量报告...希望这对您有用！
