Configuring and Compiling Nginx and PHP-FPM on Ubuntu for Magento, Part 2

| Comments

This is the second part of my little guide to get Magento running on Nginx with PHP-FPM and APC. Check out Part 1 here and Part 3 here.

In this part, we compile PHP-FPM and get it working with the APC “Accelerator” cache for Nginx. The first step is to compile PHP-FPM. Some of this is taken almost verbatim from the FPM readme:

# aptitude install -y libxml2-dev libevent-dev libjpeg-dev
# export LE_VER=1.4.12-stable
# wget "$LE_VER.tar.gz"
# tar -zxvf "libevent-$LE_VER.tar.gz"
# cd "libevent-$LE_VER"
# ./configure && make
# DESTDIR=$PWD make install
# export LIBEVENT_SEARCH_PATH="$PWD/usr/local"
# export PHP_VER=5.2.11
# cd ~/sources
# wget "$PHP_VER.tar.gz"
# tar -zxvf "php-fpm-0.6~$PHP_VER.tar.gz"
# ./php-fpm-0.6-5.2.11/generate-fpm-patch
# wget "$PHP_VER.tar.gz/from/"
# tar xvfz "php-$PHP_VER.tar.gz"
# cd "php-$PHP_VER"
# patch -p1 < ../fpm.patch
# ./buildconf --force
# mkdir fpm-build && cd fpm-build
# aptitude install libxml2-dev libbz2-dev libpcre3-dev libmcrypt-dev libmhash-dev libmhash2 libcurl4-openssl-dev libsyck0-dev libgd-dev zlib1g-dev
# ../configure --with-fpm --with-libevent="$LIBEVENT_SEARCH_PATH" --enable-mbstring --with-zlib --enable-zip --with-mcrypt --with-jpeg-dir=/usr/lib --with-gd --without-sqlite --without-pdo_sqlite --enable-fastcgi --with-curl --with-mhash --with-mysql=/etc/mysql/ --enable-pdo=shared --with-pdo-mysql=shared
# make all install
# make test
# aptitude install m4 autoconf
# mount -o remount,exec,suid /tmp
# pecl install apc
# cp /root/sources/php-5.2.11/php.ini-recommended /usr/local/lib/php.ini
# ln -s /usr/local/lib/php.ini /etc/php/php.ini
# ln -s /etc/php-fpm.conf /etc/php/php-fpm.conf

At the end of the commands above, you will notice we installed APC. Now, in /etc/php/php-fpm.conf there are four places you need to change the user and group to the correct ones for the web server. On my install, the user and group were both www-data:

&lt;value name="owner"&gt;www-data&lt;/value&gt;
&lt;value name="group"&gt;www-data&lt;/value&gt;
&lt;value name="user"&gt;www-data&lt;/value&gt;
&lt;value name="group"&gt;www-data&lt;/value&gt;

To set up some basic parameters for the PHP-FPM FastCGI install, create the file /etc/nginx/fastcgi_params. We will be importing this into the Nginx config files later. This is what I am using, but you may need to tweak yours for better performance:

fastcgi_connect_timeout 60;
fastcgi_send_timeout 180;
fastcgi_read_timeout 180;
fastcgi_buffer_size 128k;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_intercept_errors on;

Lastly, edit your php.ini file /etc/php/php.ini to enable PDO on mySql (which Magento needs) and APC. To do so, add the following lines:

extension_dir = /usr/local/lib/php/extensions/no-debug-non-zts-20060613
extension =
extension =
extension =
apc.enabled = 1
apc.shm_size = 96
apc.include_once_override = 1

I remember there being some sort of confusion the first time I tried setting the extension_dir, so check and make sure that it’s correct for your environment. It might also be /usr/lib/php5/20060613.

There, nothing to it! You should have PHP-FPM running now. The final step is to create the Nginx config files so requests for PHP are passed over to PHP-FPM for processing. This is covered in Part 3, along with some Magento specific Nginx config options.
