body: <p>I tried ,but didn't work for me.</p>
  
  <p>Apache 2.4 on CentOS 6.6:</p>
  
  <p>Step 1:</p>
  
  <pre><code>cd /etc/yum.repos.d/
  wget http://repos.fedorapeople.org/repos/jkaluza/httpd24/epel-httpd24.repo
  </code></pre>
  
  <p>Step 2:</p>
  
  <pre><code>yum install httpd24.x86_64
  </code></pre>
  
  <p>Step 3:</p>
  
  <pre><code>$ /opt/rh/httpd24/root/usr/sbin/httpd -version
  Server version: Apache/2.4.6 (Red Hat)
  Server built:   Sep 25 2013 05:25:46
  NOTE: config files are in: /opt/rh/httpd24/root/etc/httpd
  
  $ ls
  conf  conf.d  conf.modules.d  logs  modules  run
  EDIT: in case you want to switch off Apache 2.2
  
  $ chkconfig httpd off
  $ chkconfig --list | grep httpd
  httpd           0:off   1:off   2:off   3:off   4:off   5:off   6:off
  httpd24-httpd   0:off   1:off   2:off   3:off   4:off   5:off   6:off
  EDIT 2: http://wiki.apache.org/httpd/PHP-FPM

  /etc/init.d/php-fpm start
  </code></pre>
