php on cpanel server

[anewday]

My existing server with all my websites has cpanel 11, mysql 4,1, and php 4.4.7 installed. If I'm installing litespeed and PHP 5 LSAPI for the first time, can I use the existing php on the server or do I need to recompile? If the latter, will it conflict with the one already installed? I lost the link to the instructions on how to compile it via the GUI. Please advise. Thank you.

You need to recompile, install it to a different directory, it will not conflict with existing installation. It is recommended to keep cPanel installation and LSAPI installation in sync.

So, upgrade your cPanel installation to PHP5, then build Litespeed PHP with similar configuration parameters.

The instruction for the GUI is in the wiki of compiling PHP and cPanel+LiteSpeed.

Is it ok if I leave my Cpanel PHP at 4.4.7 and install LSAPHP 5 for Litespeed in a different directory? Thank you.

You can do that, this two will not interfere with each other. However, you may have compatibility issue as some PHP script written for 4.4.7 which may not work that well under PHP 5, it has nothing to do with LiteSpeed.
I think you should at least upgrade cPanel PHP to 4.4.8, and install LSAPI php 4.4.8 as well, after everything working properly, start to convert your site from PHP 4 to PHP 5 one by one. LiteSpeed can run both PHP 4 & 5 at the same time.

Ok, below is a confusing on the wiki.

Just remember to upgrade both LiteSpeed PHP and Apache mod_php later together if you want to keep both LiteSpeed and Apache work properly. Mixing different version of PHP together may break you PHP installation.

You said I can just install Litespeed + LSAPI PHP and leave cPanel PHP alone. And mixing different version should be ok, right?

[mistwang]

Yes, it is OK. That statement is based on the assumption that you install cPanel PHP and LiteSpeed PHP to the same location.

Ok, thanks a lot for the clarification. Great support here.

Hi,

Can you tell me which configure parameters won't work with build PHP 5.25 in the GUI?

'--prefix=/usr/local'
'--with-xml'
'--enable-bcmath'
'--enable-calendar'
'--with-curl'
'--enable-exif'
'--with-swf=/usr/local/flash'
'--enable-ftp'
'--with-gd'
'--with-jpeg-dir=/usr/local'
'--with-png-dir=/usr'
'--with-xpm-dir=/usr/X11R6'
'--with-gettext'
'--enable-magic-quotes'
'--with-mysqli'
'--with-mysql=/usr'
'--with-openssl'
'--enable-discard-path'
'--with-pear'
'--enable-sockets'
'--enable-track-vars'
'--with-ttf'
'--with-freetype-dir=/usr'
'--enable-gd-native-ttf'
'--enable-wddx'
'--with-xmlrpc'
'--with-zip'
'--with-zlib'

Also, why isn't --with-litespeed included in the default configure parameters? Also, how do I enable PHP 5 only for my websites? I see that PHP4 and PHP5 are installed by default. Thanks for your help.

--with-litespeed will be added automatically by the GUI tool.
If you want to install PHP to a different directory that cPanel does, you should remove '--prefix=/usr/local'.
All the configuration parameter should work, if it does not, just build PHP in cPanel with similar configuration, cPanel will fix all dependencies.
