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>
      </table>
    </div>
    
    1. 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>
        </table>
      </div>

      JSON on RHEL & PHP 5.1.6

      Stuck with PHP 5.1.6 on RHEL or even CentOS (and a sysadmin who insists on using packages)? Need JSON? I did. The solution is easy:

      yum install php-devel<br /> pecl install json

      The pecl install failed when it hit an 8MB memory limit, and I was clueless about how to fix it until I learned that the pecl installer ignores the php.ini. Turns out the best solution is to use the pear installer (which does follow php.ini settings):

      pear install pecl/json
