Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have a general question, and then a narrower one. The general question:
On a system with a 64-bit Xeon (Intel EM64T) CPU, how much does one lose (if anything) by installing the 32-bit version of an application instead of the 64-bit version? What happens when the 32-bit app talks to the 64-bit OS? Is there some kind of thunking or context switching that has to happen? If so, is it significantly time consuming?
The narrower question:
I'm installing MySQL 5 on a Dell PowerEdge with a 64-bit Xeon (Intel EM64T) CPU. After installing the 64-bit RPM's, and try to start the Apache web server, I get the following:
[root@edge rhel4-em64t]# service httpd start
Starting httpd: Syntax error on line 6 of /etc/httpd/conf.d/auth_mysql.conf:
Cannot load /etc/httpd/modules/mod_auth_mysql.so into server: libmysqlclient.so.14: cannot open shared object file: No such file or directory
I found out that in this case one must install the "compat" version of the shared library instead of the "standard version".
I've found the 32 bit one (MySQL-shared-compat-5.0.18-0.i386.rpm) but cannot find a 64 bit version. Does it exist? If not, how can I get MySQL 5 to work in 64 bit mode? I'd prefer an rpm to building it myself so that the package manager has knowledge of it.
