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

[Ryan Stille]

Oh Travis, thats really not the answer I wanted to hear...  ;-)

I have done it that way for many years, but at my new job I am trying to 
go the rpm route.  I'm the only guy there with Linux administration 
experience, and I want to make it easier for the others if they need to 
do something in my absence.

The PHP5.0 packages in the repository a few months ago were compiled 
against MySQL 4.  So now that they've moved to PHP 5.1, they've decided 
to compile it against MySQL 5?  It doesn't make a whole lot of sense to 
me.  It was a minor version increment on the PHP side, forcing a *major* 
version change to MySQL.  And I mean major, I haven't had good luck in 
the past moving to MySQL 5 without breaking stuff.

So anyway, putting that aside - PHP5.1.3 is compiled with MySQL 5.x 
libraries.  Ok.  But those client libraries can connect to a MySQL 4.x 
server just fine.  So isn't there a way I can install the PHP5.1.3 
stuff, including whatever client libraries it needs, without updating my 
MySQL *server* to 5.x?    This wouldn't be an issue at all if my 
webserver and database server weren't on the same machine.  I really 
think there's a way I can update the client stuff to 5 without updating 
the server, no?
