Upgrading Process

Download the latest php source, currently at version 5.2.5, from php.net.

wget http://us2.php.net/distributions/php-5.2.5.tar.bz2

Unpack the PHP source.

tar -jxvf php-5.2.5.tar.bz2

Change directory to php-5.2.5/sapi

cd php-5.2.5/sapi

Download the latest PHP LSAPI source, currently at version 4.4, from litespeedtech.com

wget http://www.litespeedtech.com/packages/lsapi/php-litespeed-4.4.tgz

Unpack the PHP LSAPI source.

tar -zxvf php-litespeed-4.4.tgz

Change directory to the parent directory. You should now be in the base directory of the PHP source

cd ..

Run:

touch ac*
./buildconf --force

Configure PHP source for compile. Run ./configure --help for all options. The below options are enough to support Gallery running on a PostgreSQL database.

./configure --prefix=/usr/local/php5 --with-litespeed \  
--with-config-file-path=../php --with-pgsql --with-exif --enable-bcmath \
--with-gd --with-jpeg-dir=/usr/lib --with-png-dir=/usr/lib --with-gettext

Compile PHP.

make

Change directory to the fcgi-bin folder in your Litespeed webserver installation.

cd /usr/local/lsws/fcgi-bin

Move the current lsphp binary.

mv lsphp lsphp.old

Copy the new lsphp from the source PHP source tree.

cp ~/php-5.2.5/sapi/litespeed/php ./lsphp

Test the new lsphp binary. Notice (litespeed) in the output.

# ./lsphp -v

We compiled PHP to look in ../php for its configuration file. This corresponds to the PHP folder in the base of the litespeed webserver installation. This is where you should have your php.ini file. If you need a default php.ini copy php.ini-recommended from the based of the PHP source tree.

Prerequisites

First off you will need to make sure that you install Perl Compatible Regular Expression or PCRE for short. This will enable the correct processing of the configuration file. This installation process is different then most because it is a two step procedure for nginx. I will go over that when I go over the installation of Nginx. To install PCRE, follow the next section.

Note: Make sure that /opt/local is in your path, to check this type the following command.

echo $PATH

Installing PCRE

mkdir -p /opt/local/src
cd /opt/local/src
wget ftp://ftp.csx.cam.ac.uk:21//pub/software/programming/pcre/pcre-7.3.tar.gz
gunzip pcre-7.3.tar.gz
tar -xf pcre-7.3.tar
cd pcre-7.3
./configure --prefix=/opt/local

Configure Compile and Install

The configure options I used was the following:

./configure --with-pcre=/opt/local/src/pcre-7.3 \
            --prefix=/opt/local --user=webservd --guest=webservd

Note: PCRE directory included in the configure statement is NOT the prefix to the pcre installation directory but it is indeed the source code directory of which version PCRE that we just installed.

make
make install

Once the Nginx configuration has been modified to suite your needs then you are all set to run your new and improved extreme fast, stable, and secure web server.
