Установка XCache 1.3.0 на Debian 5 Lenny

Ставим зависимости:

apt-get install -y php5-dev

Собираем:

cd /usr/src
wget http://xcache.lighttpd.net/pub/Releases/1.3.0/xcache-1.3.0.tar.gz
tar -xf xcache-1.3.0.tar.gz
cd xcache-1.3.0
phpize
./configure --enable-xcache
make
make install

Создаем конфиг:

vi /etc/php5/conf.d/xcache.ini

Со следующим содержимым:

Все :) После этой фичи продакшен сервер лег насмерть с ла уходящим за 70 и помог только резет. Софтег, однако.
