Install PHP 5 on Red Hat Enterprise Linux version 4

It appears that many people or sys admin want to run php 5 on Red Hat Enterprise Linux. Unfortunately Redhat does not provide this package (RPM file) for RHEL. You can download source code and install php 5 from official php site. This requires compiler collection on your system. Download source code and just follow instructions presented in INSTALL or REDME file.

Another option is search and installs PHP 5 packages. You can download x86_64 PHP 5 package here. Use wget command to download these packages and rpm command to install new packages. But first remove old php4 package using rpm -e command.

Alert: This post is outdated. Please use the latest version of RHEL/CentOS v6.x+ for PHP 5.x. The author no longer support php 5 rpm on RHEL 4.x.

However these rpm packages 64 bit so if you are running 32 bit os rebuild RPM file.

Step # 1: Download src rpm

# cd /tmp
# wget http://www.cyberciti.biz/files/lighttpd/rhel4-php5-fastcgi/php-5.1.4-1.esp1.src.rpm
# rpm -ivh php-5.1.4-1.esp1.src.rpm

Step #2: Rebuild RPM for 32 bit RHEL version

# cd /usr/src/redhat/SPECS
# rpmbuild -bb php.spec

It will take some time to compile and rebuild RPM files.

Step #3: Install new php5 RPM file

Remove old php4 rpm. Go to /usr/src/redhat/RPMS directory and install PHP5 RPM files.

Please note that PHP 5 is not official supported by Red Hat on RHEL 4.0. You are using these packages on your own risk ;)

Q. I need to build a source RPM, how do I build it?

A. In order to build a source RPM you need to use rpmbuild command. rpmbuild is used to build both binary and source software packages. A package consists of an archive of files and meta-data used to install and erase the archive files. The meta-data includes helper scripts, file attributes, and descriptive information about the package. Packages come in two varieties: binary packages, used to encapsulate software to be installed, and source packages, containing the source code and recipe necessary to produce binary packages.

You need to use .spec file to build the RPM file. Next type rpmbuild command as follows:

# rpmbuild -ba pakagename.spec
