Install

First, install the tools needed to build XCache:

/usr/bin/apt-get install php5-dev make

Set the version of XCache you want to install:

VERSION=1.3.0

You can now download the XCache sources:

/usr/bin/wget http://xcache.lighttpd.net/pub/Releases/$VERSION/xcache-$VERSION.tar.gz \
    --output-document=/tmp/xcache-$VERSION.tar.gz

Extract the contents of the archive:

/bin/tar --directory=/tmp -xzf /tmp/xcache-$VERSION.tar.gz

And go to the created folder:

cd /tmp/xcache-$VERSION

You can now build XCache:

/usr/bin/phpize --clean
/usr/bin/phpize
./configure --enable-xcache
/usr/bin/make
/usr/bin/make install

Once the build is done without errors, configure PHP to use XCache:

/bin/cp /tmp/xcache-$VERSION/xcache.ini /etc/php5/conf.d/xcache.ini
/bin/sed -i -e 's/^zend_extension_ts.*/; \0/' \
            -e 's/^\(zend_extension =\).*/\1 \/usr\/lib\/php5\/20060613+lfs\/xcache.so/' \
         /etc/php5/conf.d/xcache.ini

And setup the amount of memory you want to use for cache:

/bin/sed -i -e 's/^\(xcache\.size[ ]*=\).*/\1 64M/' \
            -e 's/^\(xcache\.var_size[ ]*=\).*/\1 64M/' \
         /etc/php5/conf.d/xcache.ini

Note: If you plan to use XCache with Symfony, you need to disable the admin authentification in order to allow your symfony code to use the xcache_count function:

/bin/sed -i -e 's/^\(xcache\.admin\.enable_auth[ ]*=\).*/\1 Off/' \
         /etc/php5/conf.d/xcache.ini

And restart your HTTP server:

• For Apache 2:
  

  /etc/init.d/apache2 force-reload

• For Lighttpd:
  

  /etc/init.d/lighttpd force-reload
