我想安装Percona 5.7，但是当我运行相关的yum命令时，它告诉我与Percona-Server-shared-51有57次冲突。 我真的不知道为什么我安装了，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 我可以轻松地卸载56版本，但仍然遇到与51相同的冲突。
当我试图去除这个问题时，我碰到了这个问题：
yum remove Percona-Server-shared-51 Removing: Percona-Server-shared-51 x86_64 5.1.73-rel14.12.625.rhel6 @percona-release-x86_64 5.9 M Removing for dependencies: cronie x86_64 1.4.4-15.el6_7.1 @updates 174 k cronie-anacron x86_64 1.4.4-15.el6_7.1 @updates 43 k crontabs noarch 1.10-33.el6 @anaconda-CentOS-201311291202.x86_64/6.5 2.4 k munin noarch 2.0.25-11.el6 @epel 535 k munin-node noarch 2.0.25-11.el6 @epel 1.3 M postfix x86_64 2:2.6.6-6.el6_7.1 @updates 9.7 M 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，否则会遇到问题？ 我会失去这些软件包当前设置的configuration吗？
谢谢！
如果我卸载所有的56包，然后尝试安装57服务器/客户端（不共享），我得到这个输出：

你应该保持Percona-Server-shared-51。 剩下的可以卸载。
你只需要：
yum remove Percona-Server-client-56-\* Percona-Server-shared-56-\* Percona-Server-server-56-\* yum install Percona-Server-server-57 Percona-Server-client-57
你可以看到依赖关系：
sudo yum deplist postfix|egrep -i "mysql|percona"
