Installing PHP APC On RHEL/CentOS

  1. Yum up some packages:

    ``` yum install php-pear php-devel httpd-devel

          </td>
        </tr>
      </table>
    </div>
    
    2. Install APC using pear (the pear installer is smarter than the pecl installer):
      
    When the installer asks about APXS, say ‘no’. </p> <div class="wp_syntax">
      <table>
        <tr>
          <td class="code">
            ```
    pear install pecl/apc
    
      </td>
    </tr>
    

  2. Tell PHP to load APC:

    ``` echo extension=apc.so > /etc/php.d/apc.ini

          </td>
        </tr>
      </table>
    </div>
    
    4. Restart Apache: <div class="wp_syntax">
      <table>
        <tr>
          <td class="code">
            ```
    /sbin/service httpd graceful
    
      </td>
    </tr>
