title: Using httpd 2.4 instead of 2.2 on centos 6
body: <p>I use Centos 6.5, I've installed apache 2.2 on my server by yum, I want to upgrade my apache to 2.4, but yum not support that, so I download apache 2.4.7 and install it to opt/apache/httpd-2.4.7 follow the tutorial here: <a href="https://stackoverflow.com/questions/20112355/apache-2-4-x-manual-install-on-rhel-6-4-no-apache-modules-will-load-on-start">Apache 2.4.x Manual install on RHEL 6.4 - No apache modules will load on start</a> . I want to change environment variables to new apache version to write apache 2.4 modules (change include folder for header file, change "modules" folder when build with apxs,...). I think I must install another httpd-devel for apache 2.4.7, because I still not install httpd-devel-2.4.7, but I don't know how to install and use it instead of httpd-devel-2.2 by yum. I can not describe my problems clearly in English, so I hope you can understand it. I'm a newbie and I really need your help. Thank you!</p>
