linux-logoHow to install APC on Linux ?

Ans:

The Alternative PHP Cache (APC) is a free and open opcode cache for PHP. Its goal is to provide a free, open, and robust framework for caching and optimizing PHP intermediate code. Besides being a opcode cache it provides a user cache for storing application data.

APC is  a free, open, and robust framework for caching and 
intermediate code. Here are the most simple steps :

# Login to the server as root and then

cd /usr/local/src

wget http://pecl.php.net/package/APC

eg : wget http://pecl.php.net/get/APC-3.0.19.tgz

# Extract it

tar -xzf APC-3.0.19.tgz
cd APC-3.0.19
phpize
./configure --enable-apc --enable-apc-mmap --with-apxs --with-php-config=/usr/local/bin/php-config
make
make install

Check  php.ini file path by using following command

php -i | grep php.ini

This will usually return /usr/local/Zend/etc/php.ini on a server that has Zend optimizer installed. Now edit php.ini and add the APC extension.

vi /usr/local/Zend/etc/php.ini
OR
vi /usr/local/lib/php.ini

Scroll down to the bottom and add the fallowing before the lines about the zend optimizer (They start with [Zend])

extension=”/apc_location/apc.so”

# restart Apache

service httpd restart
