NOTE
Red Hat Directory Server is also supported running on a virtual guest on a Red Hat Enterprise
Linux virtual server.
Both Red Hat Enterprise Linux versions on both 32-bit and 64-bit platforms have the same system
requirements, as listed in T able 2.2, “Red Hat Enterprise Linux Operating System and Hardware
Requirements”. The patches required are listed in Section 2.3.1, “Red Hat Enterprise Linux Patches”,
and the recommended system configuration changes are described in Section 2.3.2, “Red Hat Enterprise
Linux System Configuration”.
Table 2.2. Red Hat Enterprise Linux Operating System and Hardware Requirements
Criteria Requirements
Operating System Red Hat Enterprise Linux 4 or 5 with the latest
patches and upgrades
CPU Type Pentium 4 or higher; 2 GHz or higher
Memory/RAM 1 GB minimum, up to the system limit
Hard Disk 4 GB minimum
Other To run the Directory Server using port numbers
less than 1024, such as the default port 389, you
must setup and start the Directory Server as
root, but it is not necessary to run the Directory
Server as root.
2.3.1. Red Hat Enterprise Linux Patches
The default kernel and glibc versions for Red Hat Enterprise Linux 4 and 5 are the only required
versions for the Red Hat Directory Server host machine. If the machine has a single CPU, the kernel
must be presented in the form kernel-x.x.x.x. If the machine has multiple CPUs, the kernel must be
presented the form kernel-smp-x.x.x.x. T o determine the components running on the machine, run
rpm -qa.
Run the dsktune utility to see if you need to install any other patches. dsktune helps verify whether
the appropriate patches are installed on the system and provides useful information for tuning your
kernel parameters for best performance. For information on dsktune, see Section 2.2, “Using dsktune”.
