2.2.2. Red Hat Enterprise Linux 4 and 5

Directory Server is supported on two versions of Red Hat Enterprise Linux:
  • Red Hat Enterprise Linux 4 AS and ES on x86 and x86_64 platforms
  • Red Hat Enterprise Linux 5 Server on x86 and x86_64 platforms

NOTE

Red Hat Directory Server is also supported running on a virtual guest on a Red Hat Enterprise Linux 5 virtual server.
Both Red Hat Enterprise Linux versions 4 and 5 on 32-bit and 64-bit platforms have the same system requirements, as listed in Table 2.2, “Red Hat Enterprise Linux Operating System and Hardware Requirements”. The patches required are listed in Section 2.2.2.1, “Red Hat Enterprise Linux Patches”, and the recommended system configuration changes are described in Section 2.2.2.2, “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 3 or higher; 500MHz or higher
Memory/RAM
256 MB minimum
Up to the system limit (on 32 bit systems, typically 3 GB RAM or 4 GB RAM with hugemem kernel) for large environments
Hard Disk
200 MB of disk space minimum for a typical deployment
2 GB minimum for larger environments
4 GB minimum for very large environments (more than a million entries)
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.

2.2.2.1. 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. To 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 2.2.1, “Using dsktune”.
