system administration

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>

3. 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 Be Better Dork: Command Line Stuff Be geeky and look at the Apache modules: ``` /usr/sbin/httpd -l Compiled in modules: core.c prefork.c http_core.c mod_so.c ``` Set your path: ``` PATH=$PATH:/usr/sbin export PATH ```
