CONFIGURE & COMPILE PHP4

[root@server]# cd php-4.4.7

[root@server]# ./configure '--prefix=/usr/local/php4' '--bindir=/usr/bin' '--sbindir=/usr/sbin' '--sysconfdir=/etc' '--datadir=/usr/share' '--includedir=/usr/include'
'--libdir=/usr/lib' '--libexecdir=/usr/libexec' '--with-libdir=lib' '--with-config-file-path=/usr/local/php4/lib' '--with-pic' '--disable-rpath' '--with-exec-dir=/usr/bin' '--with-png-dir=/usr' '--enable-gd-native-ttf' '--without-gdbm' '--with-gettext' '--with-iconv' '--with-jpeg-dir=/usr' '--with-png' '--with-zlib' '--enable-exif' '--enable-ftp' '--enable-magic-quotes' '--enable-sockets' '--enable-track-vars' '--enable-trans-sid' '--enable-yp' '--enable-wddx' '--with-pear=/usr/share/pear' '--enable-calendar' '--with-libxml-dir=/usr' '--with-xml' '--enable-force-cgi-redirect' '--enable-pcntl' '--enable-mbstring' '--enable-mbregex' '--with-ncurses' '--with-gd' '--enable-bcmath' '--with-xmlrpc' '--with-mysql' '--with-mysqli' '--enable-dom' '--with-xsl' '--enable-fastcgi' '--program-suffix=4' '--with-expat-dir=/usr'

Note :: You may get too many errors while configuring PHP which can be easily resolved by installing required devel through YUM (For exa:: yum install libmhash-devel), also you can always choose to remove an option above from the compile command if you can't or don't want to install a dependency..


Once the complie command succeeds, run:

make

then

make install

then Copy php source files.

[root@server]# cp -rf ./sapi/cgi/php /usr/local/php4/bin/
[root@server]# mkdir -pv /etc/httpd/cgi-sys/
[root@server]# cp -rf ./sapi/cgi/php /etc/httpd/cgi-sys/
[root@server]# cp -rf php.ini-recommended /usr/local/php4/lib/php.ini

Make a php4.conf file:

The previous PHP5 installation created a the file /etc/httpd/conf.d/php.conf- duplicate this file and rename it php4.conf, then edit the "DirectoryIndex" "Action" and "AddHandler" lines with the following information:

DirectoryIndex index.php4 index.php3
Action php4-script /cgi-bin/php
AddHandler php4-script .php3 .php4

and comment out the "LoadModule php5..." line

Instead of creating "php4.conf" you can add following lines at the bottom of the file /etc/httpd/conf/httpd.conf

ScriptAlias /cgi-sys/ /etc/httpd/cgi-sys/
Action application/x-httpd-php4 "/cgi-sys/php"
AddHandler application/x-httpd-php4 .php4

and then restart Apache:
[root@server]# /etc/init.d/httpd restart

Create link to PHP4 in Client's cgi-bin Directory
# Due to Security Issues the PHP4 CGI is installed at /usr/local/etc/php4/cgi/php.ini. In the Interworx virtual host setup using suexec, each user has their own cgi-bin. Do the following to link the PHP4 CGI into your hosting client's cgi-bin directory.

[root@server]# cd /chroot/home/client/public_html/cgi-bin
[root@server]# ln /usr/local/php4/bin/php php
[root@server]# chown client php
[root@server]# chgrp client php
[root@server]# chmod 755 php

Test your PHP installation
try creating a php.info doc for both versions of PHP:

/chroot/home/client/public_html/info.php4
/chroot/home/client/public_html/info.php
using the same code:

phpinfo();
?>

The phpinfo() function reports the version number, as well as the features that are compiled into PHP. You'll see that info.php4 uses php4 and info.php5 uses php5.
