End of Life – PHP version 4 webhosting

PHP version 4 was officially retired 8 years ago and no longer receives any kind of official patches or support. To preserve functionality for our resellers who have customer services requiring PHP v4 we have maintained our own patch subset for PHP v4 since 2008.

Our volume of PHPv4 websites has now reached a low enough level that it no longer makes business sense to maintain our PHPv4 Webhosting services. Effective 1 August 2017, we will no longer offer / support PHPv4 websites.

We recommend to all customers to either upgrade their websites to PHPv5, PHPv6, or PHPv7. You can select the different version from our webhosting panel to temporarily change your php version to see how it may affect your website. We would recommend trying PHP 5.2.

If you need help with migration we recommend placing a RackCorp support ticket. Any sites still operating on PHPv4 will be automatically upgraded to PHPv5.2 on August 1st. Please note there is a VERY HIGH chance that this will break sites that were built for PHPv4.

RackCorp welcomes Melbourne to our global network

We are pleased to announce high-availability premium virtual servers via in Metronode’s recently completed Melbourne 2 Data Centre located in Victoria, Australia.

This data centre is unique in that not only does it allow us to offer hosting and server products in a location geographically convenient to Southern Australian users, but provides very high security and energy efficiency features.

Our Melbourne point of presence is ideal for customers in Victoria, South Australia and especially Tasmania who are seeking the best latency and speeds to their websites.


RackCorp’s in-house developed management system and global network

Combined with Metronode’s Tier 3 Rating means our Melbourne site is ideal for customers who require a higher level of redundancy and reliability

What Exactly is a Tier 3 rating?

A specification defined by both the Uptime institute and ANSI/TIA of USA which contains formal requirements for the design of a data centre.

Tier III Certified

The rating covers items such as

  • Site space and layout
  • Physical infrastructure such as cabling, site security, access control and power.
  • Reliability rating of the sites infrastructure
  • Environmental efficiency and Management, both internal and external

Very few data centres in Australia are Tier 3 rated as a number are just designed to best-practise rather than an industry recognised specification.

Energy Efficiency – the future key to reliable web hosting

A commonly cited metric to measure a data centre is its PUE (power utilization efficiency) rating. The lower the PUE, the more efficient the cooling, better the reliability with less chance of outages and the lower the energy costs.

Metronode’s unique ‘BladeRoom’ data hall design and Melbourne’s cool climate enable a very low PUE of 1.1, one of the lowest possible and best in Australia.

Apache 2 + FastCgi + PHP 5 compile / build

Building the three of these is fairly easy, but a bit tricky if you’re used to how it worked in previous versions of Apache or PHP.  Please note that we install everything into prefix trees and use a tool called graft to manage the versions.  If you simply install your versions into default locations, you can probably leave out anything to do with prefix=, and top_dir.  We also download all install archives into /usr/local/PKG_BUILD.

Anyway to get started, the first trick is to build Apache 2 first by itself.  Here is an example:

cd /usr/local/PKG_BUILD
tar -xvzf httpd-2.2.8.tar.gz
cd httpd-2.2.8
./configure –prefix=/usr/local/PACKAGES/httpd-2.2.8 –enable-file-cache –enable-cache –enable-deflate –enable-mime-magic –enable-expires –enable-headers –enable-version –enable-ssl –enable-http –enable-cgi –enable-rewrite –enable-so –with-ssl=/usr/local/PACKAGES/openssl-0.9.8
make install

This will install Apache into /usr/local/PACKAGES/httpd-2.2.8.  If you want to make some modules shared (such as how we’re going to build mod_fastcgi shortly) then you can do so by adding things like: –enable-rewrite=shared.

The first part of installing fastcgi is to download fcgi from  To install this:

cd /usr/local/PKG_BUILD
tar -xvzf fcgi-2.4.0.tar.gz
cd fcgi-2.4.0
./configure –prefix=/usr/local/PACKAGES/fcgi-2.4.0
make install

The next step is to download mod_fastcgi (this is a DIFFERENT package to the fcgi one).  You can also download this from

cd /usr/local/PKG_BUILD
tar -xvzf mod_fastcgi-2.4.6.tar.gz
cd mod_fastcgi-2.4.6
cp Makefile.AP2 Makefile
make top_dir=/usr/local/PACKAGES/httpd-2.2.8/
make install top_dir=/usr/local/PACKAGES/httpd-2.2.8/

This will actually find your httpd source and compile mod_fastcgi for you, as well as install it with the Apache 2 modules! (Easy huh?).

The final step is to download and install PHP 5.  You can obtain PHP from  After downloading:

cd /usr/local/PKG_BUILD
tar -xvzf php-5.2.4.tar.gz
cd php-5.2.4

Now the next part will no doubt differ depending upon what features you want to compile PHP with.  That’s left up to you and google to work out how to compile the other modules.  I’ll show what we compile some of our systems with, but the only ones that are really applicable to this blog are the –enable-force-cgi-redirect –enable-fastcgi ones.

./configure  –prefix=/usr/local/PACKAGES/php-5.2.4-norm –with-openssl=/usr/local/PACKAGES/openssl-0.9.8d –with-zlib –enable-force-cgi-redirect –enable-fastcgi –with-mysql=/usr/local/PACKAGES/mysql-5.0.41 –enable-static –with-config-file-path=/etc/php.ini –with-imap –with-mcrypt –with-curl=/usr/local/PACKAGES/curl-7.16.1/ –with-kerberos –with-imap-ssl
make install

And that’s it for the compiling stage.  I’ll put up a blog at a later date on how to configure Apache 2 to work with FastCgi.  Stay tuned.

php_network_getaddresses failed

We came across a problem today which we have seen a few times before. They were attempting to install wordpress akismet and when attempting to verify their API key they would always receive the following error:

There was a problem connecting to the Akismet server

This rather trivial message in this instance, and in other instances has been due to a badly set up chroot environment. The actual PHP error being generated is this one:

Warning: fsockopen(): php_network_getaddresses: getaddrinfo failed: Name or service not known

Which simply means that it could not resolve the hostname into an IP address in this instance. There is talk over at PHP bugs about it in which it has been repeated many times that this is NOT a PHP bug! Unfortunately people tend not to read before they post….

Anyway, the important files that you are going to need to make sure are in your chroot environment (with appropriate permissions) to resolve this problem are:


And if you have any wierd and wonderful domain configuration going on, you may need other libnss files too.
