HOWTO/Install PHP 4.3.x on a RAQ550

Introduction

This details the steps I took to upgrade two (going on three) RAQ550 machines and one Qube 3 to 4.3.x, and is presented more for my own future reference than as a compreehensive setup guide.

DISCLAIMER: Following this procedure will invalidate your warranty. This is not a supported upgrade path, and if you decide to do this, you're on your own. Some people have broken their administrative interface by overlooking a couple of steps and/or failing to make backups of the original Cobalt files - you have been warned.

The base procedure can be outlined as follows:

  • Make httpd.admserv fully independent
  • Get the sources and any dependent libraries you might need
  • Compile for the Cobalt layout
  • Enjoy

Isolating the admin server

Go to /usr/lib and copy /usr/lib/apache to /usr/lib/apache.admserv. For good measure, make another copy called apache.orig, since you will change the apache directory contents as well later on, and backups are always nice to have:

# cd /usr/lib
# cp -R apache apache.admserv
# cp -R apache apache.orig

Now let's make the administration server use the new apache.admserv directory: Edit the administration server's httpd.conf file to load the module from /usr/lib/apache.admserv/libphp4.so. The relevant line in the file should look like this:

# cat /etc/admserv/conf/httpd.conf | grep LoadModule | grep -i php4
LoadModule /usr/lib/apache.admserv/libphp4.so

Now has to be configured to load the custom cce.so extension. Edit the administration server's php.ini file to load extensions from /usr/lib/apache.admserv/php.

This is different from the /etc/httpd/php.ini file used by the hosted sites, since the startup scripts for each web server set the PHPRC environment variable (reading through /etc/rc.d/init.d/httpd and /etc/rc.d/init/admserv is strongly recommended for those who want to compare the hosting web server with the admin server).

Again, the relevant line is:

# cat /etc/admserv/php.ini | grep extension_dir
extension_dir = /usr/lib/apache.admserv/php

Not test it by restarting httpd.admserv:

# /etc/rc.d/init.d/admserv restart

And test it by going to the administration front-end. So far, everything you have done is easily reversible, and the hosted web sites are still running from /usr/lib/apache.

Information on recompiling was axed from the Sun Knowledge Base, so here are the command lines I used:

# cd /root/Packages
# tar -zxvf php-4.3.2.tar.gz
# mv php-4.3.2 /usr/src/
# wget http://planetmirror.com/pub/sourceforge/libpng/libpng-1.2.5.tar.gz
# mkdir ../Build
# cd ../Build/
# tar -zxvf ../Packages/libpng-1.2.5.tar.gz
# cd libpng-1.2.5/
# cp scripts/makefile.linux Makefile
# make install
# cd ../../Packages/
# wget http://www.ijg.org/files/jpegsrc.v6b.tar.gz
# cd ../Build/
# tar -zxvf ../Packages/jpegsrc.v6b.tar.gz
# cd jpeg-6b/
# ./configure ; make
# make install
# make install-lib
# make install-headers

I then searched for libttf - don't remember if it's already installed on the 550, but I recompiled the new version on the Qube without any issues - and proceeded to recompile with the following command line (you can get the command-line used to compile any version of by reading the phpinfo() output - check your manual).

# cd /usr/src/php-4.3.3/
# ./configure --prefix=/usr --with-apxs=/usr/sbin/apxs --enable-safe-mode \
--with-config-file-path=/etc/httpd/ --with-exec-dir=/usr/bin --with-zlib \
--enable-magic-quotes --with-regex=system --with-pear --enable-calendar \
--with-gd --with-iconv --disable-debug --with-gettext \
--with-ttf=/usr/lib/libttf.so --enable-mbstring --with-interbase=shared \
--with-mysql=shared --with-pgsql=shared --with-jpeg=/usr/local/lib \
--with-png=/usr/local/lib
# make
# make install
# cp modules/* /usr/lib/apache/php/
# /etc/rc.d/init.d/httpd restart

I then proceeded to change php.ini to my settings, takink special care to change the extension_dir to the new one creates upon installation. I have also added Turck MMCache to all installations with great results.

Note: If you have installed any Apache or updates from Cobalt (at least any after June 2003), it might actually be a good idea to rename /usr/lib/apache temporarily to something else and make doubly sure that the administration server is not using anything in that directory - any new updates or third-party extensions may well add more stuff to that directory that I'm not aware of.
