This blog has been migrated from Apache2 + mod_php to Nginx + PHP-FPM. In this entry I'm going to explain the whole process (just for fun).
The easiest way is just install the precompiled packages from www.dotdeb.org as explained here.
Unfortunatelly my blog isn't compatible with the latest PHP versions provided by dotdeb, so I've had to compile my own version of PHP-FPM.
Firts of all, we need to install Nginx:
apt-get install nginx
Then I downloaded the source code of PHP 5.4.3 from http://www.php.net/releases/
cd /var/tmp
wget http://museum.php.net/php5/php-5.3.4.tar.gz
tar zxvf php-5.3.4.tar.gz
cd php-5.3.4
./configure --prefix=/opt/php-5.3.4 --enable-fpm --with-mcrypt --with-zlib --enable-mbstring --disable-pdo --with-mysql --with-curl --disable-debug --disable-rpath --enable-inline-optimization --with-bz2 --with-zlib --enable-sockets --enable-sysvsem --enable-sysvshm --enable-pcntl --enable-mbregex --with-mhash --enable-zip --with-pcre-regex
make all
make install
Now, the required PHP version, including the PHP-FPM service are installed here: /opt/php5-3.4
The easiest way to get the PHP-FPM service running is by using the init script and the config files contained in the php5-fpm dotdeb package.
wget http://packages.dotdeb.org/dists/squeeze/php5/binary-i386/php5-fpm_5.3.8-1~dotdeb.2_i386.deb
dpkg-deb -x php5-fpm_5.3.8-1~dotdeb.2_i386.deb /tmp/php5-fpm
cp /tmp/php5-fpm/etc/init.d/php5-fpm /etc/init.d/php5-fpm
cp -R /tmp/php5-fpm/etc/fpm /etc/php5/
ln -s /opt/php-5.3.4/sbin/php-fpm /usr/sbin/php5-fpm
Now you should copy your previous php.ini file into the correct place: Use phpinfo () to know the correct path for the php.ini file:
/opt/php-5.3.4/bin/php -i|grep php.ini
In this case, the PHP-FPM will look for php.ini here /opt/php-5.3.4/lib, so just drop your previous file here.
cp /etc/php5/apache2/php.ini /opt/php-5.3.4/lib |
