Recompile PHP for Litespeed webserver

LSAPI is LiteSpeed’s open-source API between external applications and LiteSpeed Web Server. This how-to is for compiling and installing PHP + LSAPI on Linux, OS X, FreeBSD, Solaris, and so on.  LiteSpeed  comes with PHP 4.4.x compiled with LSAPI. To change the LightSpeed php to the latest stable one, we need to recompile the php with the LSAPI for LiteSpeed.

I  am trying to provide some info for doing this task.

Instructions:

a)  Download the required php  from php.net

wget  http://in2.php.net/get/php-5.2.11.tar.bz2/from/this/mirror

tar -xzvf  php-5.2.11.tar.bz2

cd php-5.2.11/sapi

b) Download and  the  latest LSAPI for PHP from http://www.litespeedtech.com/ into the “sapi” folder of php source:

wget http://www.litespeedtech.com/packages/lsapi/php-litespeed-4.10.tgz

tar  -xvf php-litespeed-4.10.tgz

c) Change directory to root PHP source directory and run commands:

cd ..

touch ac*

./buldconf –force

d) Configure/Compiling

If you have an  apache compilation already , remove the part   option “–with-apxs” and use    ” –with-litespeed”  . Also  you may need to change the “prefix” option too . So a basic  configure command would be like  this

./configure  ‘–prefix=/lsphp5′ ‘–with-litespeed’ ‘with-mysql’

make

make install

Note: You must compile PCRE support inorder for the default auto-index php script to work correctly

Post Install Configurations

1. Replace the existing lsphp binary with the new one.

Change the directory to the current installation of “lsws” ( it varies on different machines)

cd  /usr/local/lsws/fcgi-bin

mv lsphp lsphp.old

cp /php-5.2.11/sapi/litespeed/php lsphp-5.2.11

ln -sf lsphp5 lsphp-5.2.11

Check Installation

/usr/local/lsws/fcgi-bin/lsphp5 -v

It should return something like:

PHP 5.2.11 (litespeed) (built: Sep26 2008 14:09:09)
Copyright (c) 1997-2004 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies

Notice litespeed in parenthesis. This means that the PHP binary has litespeed (LSAPI) support builtin.

2. php.ini

The php.ini file will be located at /usr/local/lsws/php/php.ini

If we want to use the old PHP.ini just copy it here.

# cd /usr/local/lsws/php
# mv php.ini php.ini.old
# cp /usr/local/ZEND/etc/php.ini .

3. Restart Litespeed Webserver

Finally restart LSWS and use our new PHP binary.

/usr/local/lsws/bin/lswsctrl restart
