[olug] CentOS / yum users - a little help? Want to upgrade php without MySQL

Fri Mar 2 03:41:40 UTC 2007

Ryan,

I agree, it doesn't make sense to jump a major version like that,
especially when I've heard pretty mixed reviews about MySQL 5x... (for
another thread) ;)

But, to answer your question, there is a way with both Debs and RPMs
to install w/o paying attention to the required dependencies. The
option in the RPM world is:

rpm -i --force --nodeps <pkg name>

Obviously, this is not what you want to start doing if your goal is ease of use.

I really hate to ask this type of question, since it "sounds" like
this is an environment where distro change is not feasible, but...
When you're running a binary-based distribution, your options on how
things relate to each other and what gets updated when and what
version you're going to use, and what options you want compiled in are
not *yours* to choose. They're decided by whoever is rolling those
packages.

So, would moving to a different distro be an option. (no, I haven't
lost my mind, and yes, I am still on the same page with you for ease
of use) :)

Cheers!
Travis
