Good bye CentOS! Hello Ubuntu

CentOS, Linux, PHP, Reviews, Tips and Tricks, Ubuntu
Its been about almost more then two years since I have been playing with CentOS on many different platforms etc. Its very stable but on the other hand, PHP/MySQL updates are very hard to get and still PHP is 5.1.6. I tried EPEL repo and it updated PHP to 5.3.1 but still there were conflicts with stuff and many core packages. So, I thought why not move to Ubuntu since it has just announced 10.04LTS (Long Term Support) in April 2010. Folks at iWeb were really nice to do a reinstall without any charges and also process a memory upgrade request at an amazing 50% discount. Ubuntu 10.04 LTS Apache 2 version is 2.2.14 PHP version is 5.3.2 MySQL version is 5.1.41-3ubuntu12 SVN (Subversion) version is 1.6.6 As a comparison…

How to Install Apache, PHP and MySQL on CentOS

How to, Linux, OpenSource, PHP, Resources, Tips and Tricks, Tutorials
I have seen people installing Apache, PHP and MySQL from source code on a production server. You should NEVER, NEVER, NEVER install these packages from source on an RPM or DEB based Linux distributions. Did I say “NEVER” enough times to make your realize that it is not a good practice? Installing from source is bad idea; there are many reasons for this but the major one is that you will be spending a lot of time keeping the system updated. If you love installing from source then I would suggest using a different distribution e.g. Gentoo. You can build from source if the package is not available in yum but still, try to use “yum” (or “apt-get” on Ubuntu) because it will save a lot of your time when…
