使用这个 repo：http://dl.iuscommunity.org/pub/ius/stable/CentOS/6/x86_64/ius-release-1.0-13.ius.centos6.noarch.rpm对于 php 安装，
对于 Apache，我使用 amazon linux repo

httpd24-tools.x86_64 2.4.10-1.59.amzn1 @amzn-main
一切都很好，直到这个水平
现在，当我尝试为 apache:php56u.x86_64 安装 php-extension 时，
发生了以下情况：yum install php56u.x86_64

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
答案1
这里发生的事情非常清楚。php56u需要httpd来自 CentOS 基础。
但您从 Amazon 存储库安装了 httpd。
通常，IUS 与标准 CentOS/RHEL 兼容。
我非常怀疑 IUS 测试与 Amazon 存储库的兼容性（提示：IUS 是为 Rackspace 客户构建的，它由 Rackspace 赞助，而 Rackspace 几乎是 Amazon 的竞争对手……）。
