FAQ: Installation: PHP Modules
The following modules are recommended for installation in order to support various caching methods:
- php-redis
- php-memcache
- php-memcached
- php-opcache
apt-get -y install php-redis php-memcache php-memcached php-opcache
service php*-fpm restart
Using PECL:
pecl install memcached
Or manually:
cd /usr/local/src
wget http://pecl.php.net/get/memcache-2.2.6.tgz
tar -xzf memcache-2.2.6.tgz
cd memcache-2.2.6
phpize && ./configure
make && make install
Use the memcache.ini file we prepared for you:
cp /path/to/your/website/wp-content/plugins/w3-total-cache/ini/memcache.ini /etc/php.d/
Restart Apache:
/etc/init.d/httpd restart
Test module:
php -r 'phpinfo();' | grep 'memcache'
Install APC using PECL:
pecl install apc
Or manually:
cd /usr/local/src
wget http://pecl.php.net/get/APC-3.1.9.tgz
tar -xzf APC-3.1.9.tgz
cd APC-3.1.9
phpize
./configure --enable-apc --enable-apc-mmap --with-apxs=/usr/sbin/apxs --with-php-config=/usr/bin/php-config
