Chapter 1. Installing the software

php-ldap

This package provides the hooks for PHP to perform lookups in LDAP directo-

ries.

php-pgsql

This package provides the hooks for PHP to work with PostgreSQL relational

databases.

mod_auth_pgsql

This package provides the facility to use a PostgreSQL database to do password

lookups for access controls rather than the plain text ﬁles that are often used.

squid

Squid is a proxy caching server.

tux

Tux is an alternative web server. We will not be discussing tux in this course.

webalizer

Webalizer is a Web server log analysis program. We will examine its use in the

Section called Log ﬁle analysis in Chapter 7.

There are other packages released with Red Hat Linux version 9 which depend on

the httpd package and which enhance its functionality. In particular, if you want to

connect to a database running MySQL rather than PostgreSQL then the corresponding

packages are mod_auth_mysql and php-mysql.

For the purposes of this course we will need only some of the packages. We will also

make use of another system package for log rotation. This is a base system package

and should already be installed on the system.

Packages used directly in this course

• httpd

• webalizer

• logrotate

Installing the packages

Location:

We detail where to ﬁnd the packages. This element is Cambridge-speciﬁc.

rpm:

Then we describe exactly how to install the packages.

Components

Finally we review what’s actually been added to the system (before we delete large

chunks of it).

To install the packages we will have to be root. We either log in as root or su to root.

If you su please be sure to use the - option to get the right environment.
