我想安装 Percona 5.7，但是当我运行相关的 yum 命令时，它告诉我 57 与 Percona-Server-shared-51 发生冲突。我真的不知道为什么我还要安装它，因为我也有 Percona-Server-shared-56。
rpm -qa | grep Percona
Percona-Server-client-56-5.6.30-rel76.3.el6.x86_64
Percona-Server-shared-51-5.1.73-rel14.12.625.rhel6.x86_64
Percona-Server-shared-56-5.6.30-rel76.3.el6.x86_64
Percona-Server-server-56-5.6.30-rel76.3.el6.x86_64
我可以轻松卸载 56 版本，但仍然会遇到与 51 相同的冲突。
当我尝试删除它时，我遇到了这个问题：
yum remove Percona-Server-shared-51

sysstat x86_64 9.0.4-31.el6 @base 826 k
yum-cron noarch 3.2.29-73.el6.centos @base 28 k
我可以继续，然后在安装 Percona 5.7 后重新安装这些软件包，还是会遇到问题？我会丢失这些软件包当前设置的任何配置等吗？
谢谢！
如果我卸载所有 56 个软件包，然后尝试安装 57 个服务器/客户端（不共享），我会得到以下输出：
yum install Percona-Server-server-57 Percona-Server-client-57

你应该保留 Percona-Server-shared-51。其余的可以卸载。
