How to install PHP-APC in WHM/cPanel

 

If you are trying to install APC are not able to using the WHM PECL installer then try this. APC needs to be installed from source so these instructions assume you have root access to the server using a client like putty.

login to server as root and run the following commands:

 

cd ~ 
mkdir setups
cd setups 
wget http://pecl.php.net/get/APC-3.1.5.tgz 
tar -xvf APC-3.1.5.tgz 
cd APC-3.1.5
phpize
./configure --enable-apc --enable-apc-mmap --with-apxs --with-php config=/usr/local/bin/php-config
make

 

If you face any kind of error like :- 

In file included from /usr/local/src/APC-3.1.5/apc.c:38:
/usr/include/php/ext/pcre/php_pcre.h:29:18: error: pcre.h: No such file or directory

make: *** [apc.lo] Error 1
Then you need to install pcre and make sure you do this from the / directory or it will not install.

Again do:

If no errors then do:

update php.ini through WHM PHP Configuration Editor. Switch to Advanced and find Section:Core Directive:extension and add this to the end of the list:

Then restart apache and your done. the phpinfo function should show that APC is installed
 
Hope this helps someone.
