If you are running a cPanel server, you are able to use EasyApache to add and remove many PHP extensions. cPanel has the ability to also install and uninstall PHP modules on the fly using the phpextensionmgr, which can be found at /scripts/phpextensionmgr. You are able to see the usage and option by using the –help flag, as shown below.

[email protected] [~]# /scripts/phpextensionmgr --help
    phpextensionmgr [options] [action] [extension]

          --help       Help message
          --prefix     Installation prefix for PHP (normally /usr/local or /usr/local/php4)

          install      Install or update the extension
          uninstall    Uninstall the extension
          status       Display the installation status of the extension
          list         Show available extensions


As you can see, you are able to install, uninstall, display whether or not the extension is installed, or list all of the available modules. Running the list command as below will show all of the modules that are available to be added on your server.

[email protected] [~]# /scripts/phpextensionmgr list 
Available Extensions:

You can also find the status of a single module by using the status flag.

[email protected] [~]# /scripts/phpextensionmgr status Xcache

Determining status of Xcache
Xcache extension is NOT installed


If we wanted to install Xcache, we would use the install flag, which will take care of the entire install process.  Keep in mind that we are only using Xcache as an example and it’s usage will depend on your server configuration as well.

[email protected] [~]# /scripts/phpextensionmgr install Xcache
Installing Xcache
Determining PHP version
Configuring for:
PHP Api Version:         20090626

checking for cc option to accept ANSI C... none needed
(More compiling stuff)
/bin/sh /home/cpeasyapache/phpextensions/xcache/xcache-1.3.2/libtool --mode=install cp ./xcache.la /home/cpeasyapache/phpextensions/xcache/xcache-1.3.2/modules
cp ./.libs/xcache.so /home/cpeasyapache/phpextensions/xcache/xcache-1.3.2/modules/xcache.so
cp ./.libs/xcache.lai /home/cpeasyapache/phpextensions/xcache/xcache-1.3.2/modules/xcache.la
PATH="$PATH:/sbin" ldconfig -n /home/cpeasyapache/phpextensions/xcache/xcache-1.3.2/modules
Libraries have been installed in:

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Build complete.
Don't forget to run 'make test'.

rm -f libphp.la   modules/* libs/*
Got ret value 0 from system( make,clean )
Xcache extension activated
./cpanel-install exiting with exit code 0

If you wanted to remove that module, you could do so with the uninstall flag.

[email protected] [~]# /scripts/phpextensionmgr uninstall Xcache
Uninstalling Xcache
Removing xcache from /usr/local/lib/php.ini


Using /scripts/phpextensionmgr can help you to add, remove, find the status of particular modules and list the available modules.  In you day to day work, this can help you to save time by not needing to run EasyApache to install the PHP modules which can save time and unnecessary load on your server.
