 +====== CageFS Prevents Installed PHP Module From Being Loaded ======
 +
 +\\
 +
 +If you are using CageFS, you may find that your sites display errors about missing modules when the modules in fact are not missing and have just been installed. ​
 +
 +In a recent case, Bcmath was not being detected when loading the site via the browser, but Bcmath showed as enabled when checking using the following command:
 +
 +  php -m | grep -i bcmath ​
 +
 +I tested with the following PHP script further:
 +
 +  <?php
 +  if(extension_loaded('​bcmath'​)) {
 +   ​echo("<​html><​body><​p>​Yay! BCMath is loaded!</​p></​body></​html>"​);​
 +  } else {
 +   ​echo("<​html><​body><​p>​BCMath is not loaded.</​p></​body></​html>"​);​
 +  }
 +  ?>
 +
 +Running the script manually via the browser would yield "​BCMath is not loaded."​ but running the script manually would yield "Yay! BCMath is loaded!":​
 +
 +  [root@host ]# php extensiontest.php ​
 +  <​html><​body><​p>​Yay! BCMath is loaded!</​p></​body></​html>​[root@restaurantjobs public_html]# ​
 +  [root@host ]#
 +
 +With CageFS, each user has a separate caged command binary folder. Thus, any new RPM package installed must be added to the CageFS of the users who need to execute them.
 +
 +I added the package to CageFS with the command:
 +
 +  cagefsctl --addrpm ea-php53-php-bcmath
 +
 +I then forced the users' CageFS configurations to update like so:
 +
 +  cagefsctl --force-update
 +
 +The error was no longer shown in the browser. If you were to encounter this error, you could use a phpinfo page to confirm that the module is loaded after making the changes to CageFS. ​
 +
 +:)
