PECL Alternative PHP Cache (APC) Installation

Time required: 1 minute

1. Install APC using the PECL command (and skip to #5 if successful):

   # pecl install apc

2. Or via compilation. Download the latest stable version and extract:

   # cd /usr/local/src && wget http://pecl.php.net/get/APC-3.0.19.tgz && tar -xzf APC-3.0.19.tgz && cd APC-3.0.19

3. Note the paths returned for the following commands:

   # whereis php-config
   # whereis apxs

4. Use the output from #2 to modify the –with-apxs and –with-php-config flags in the following compile command:

   # phpize && ./configure --enable-apc --enable-apc-mmap --with-apxs=/usr/sbin/apxs --with-php-config=/usr/bin/php-config && make && make install

   The result should be similar to:

   Installing shared extensions: /usr/lib/php/modules/

5. You can also use the apc.ini file we prepared for you:

   # cp /var/www/vhosts/domain.com/httpdocs/wp-content/plugins/w3-total-cache/ini/apc.ini /etc/php.d/

6. Restart apache when ready:

   # /etc/init.d/httpd restart

7. You’re done! APC should now be available. If the following command retuns anything, you’re all set:

   # php -r 'phpinfo();' | grep 'apc'
