我正在使用 SCL 测试 PHP 升级。测试是在本地虚拟机上进行的，因此在我们开发程序时可以破坏一些东西。下列的SCL 存储库我能够将 Python 更新到 2.7.13 并通过 激活它profiles.d/。我现在正在尝试升级 Apache 和 PHP。
根据阿帕奇下载最新的是 Apache 2.4.29。当我尝试更新 Apache 时，yum install httpd我被告知软件包 httpd-2.4.6-67.el7.centos.6.x86_64 已安装且最新。如果我使用，yum install httpd24那么 SCL 会尝试安装 Apache 1.18。
yum search httpd没那么有帮助。它列出了软件包（有时还注明 SCL），但缺少版本号。
使用SCL程序时如何安装最新的Apache和PHP？
答案1
以下是我对 Apache、Python 和 PHP 升级的现场笔记。它也包括mod_ssl，但缺乏mod_security。我mod_security在 SCL 中找不到。
