System requirement

• – Php
• – OpenSSL

Setup

In this tutorial i have already installed Apache2 and Php 5.2.5 . I just need to add OpenSSL module on my php i also decided to upgrade my php from 5.2.5 to 5.2.9. First you need to download the Php (http://us.php.net/downloads.php) and Openssl sourcode (http://www.openssl.org/source/)

#wget http://www.openssl.org/source/openssl-0.9.8k.tar.gz
#wget http://us.php.net/distributions/php-5.2.9.tar.gz

Extract and compile the openssl

#cd /root
#tar -zxvf openssl-0.9.8k.tar.gz
#cd openssl-0.9.8k
#./config && make && make install

Extract, configure and installed the php

Before you configure the php sourcecode you must remember the previous php configuration right ? if not you can use php -i |grep configure to see the previous configuration

# php -i |grep configure
Configure Command =>  ‘./configure’  ‘–with-apxs2=/usr/local/apache2/bin/apxs’ ‘–with-mysql=/usr/local/mysql’ ‘–with-gd=/usr/local’ ‘–with-jpeg-dir=/usr/local/lib’ ‘–with-zlib-dir=/usr/local’ ‘–with-ftp’ ‘–with-gif’ ‘–enable-ftp’ ‘–with-png-dir=/usr/local/lib’ ‘–with-freetype-dir=/usr/local’ ‘–with-curl=/usr/local’

Now you have the config list, start the php installation

#cd /root
#tar -zxvf php-5.2.9.tar.gz
#cd php-5.2.9
./configure –with-openssl=/usr/local/ssl  –with-apxs2=/usr/local/apache2/bin/apxs –with-mysql=/usr/local/mysql –with-gd=/usr/local –with-jpeg-dir=/usr/local/lib –with-zlib-dir=/usr/local –with-ftp –with-gif –enable-ftp –with-png-dir=/usr/local/lib –with-freetype-dir=/usr/local –with-curl=/usr/local

#make
#make install

And the last thing don’t forget to restart your apache2

#/usr/local/apache2/bin/apachectl stop

#/usr/local/apache2/bin/apachectl start

Now check your openssl module

# php -m | grep openssl
openssl
if you see openssl it means you did it
