How 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
