Novell Documentation: Nterprise Linux Services

NNLS Server

The following sections outline the basic requirements for an NNLS server.

Server Hardware Requirements

Install NNLS only on a machine that meets the following requirements.

Server-class computer
Manufacturer and model: _______________________________________________
Pentium* II processor (Pentium 4 at 1.5 GHz recommended)
Processor model and speed: ____________________________________________
512 MB RAM minimum (1 GB recommended)
Total RAM required: ______________________

NOTE: The RAM amounts shown here are for system components only. The NNLS service components you install might require additional RAM.
Be sure to complete the planning instructions found in the Novell Nterprise Linux Services Overview, Planning, and Implementation Guide for each component you install. During that planning process, you are instructed to record and track the additional RAM you need on this sheet.
30 GB free disk space
Total disk space required: ________________________

NOTE: The disk space amount shown here is for system components only. The NNLS service components you install (such as file services) require additional disk space.
Be sure to complete the planning instructions found in the Novell Nterprise Linux Services Overview, Planning, and Implementation Guide for each component you install. During that planning process, you are instructed to record and track the additional disk space you need on this sheet.

System Software Requirements

IMPORTANT: NNLS must be installed on a server that contains only a newly installed operating system with its accompanying utilities, etc.

One of the following operating systems:
- Red Hat Enterprise Linux AS 2.1
- Red Hat Enterprise Linux ES 2.1
- SuSE Linux Enterprise Server 8.0
The gettext RPM (for eDirectory^TM to function correctly)
This package is needed if you are using a response file to install NNLS for both Express and Custom noninteractive installations.

Server Network Configuration

IMPORTANT: As explained in Use a Static IP Address, the NNLS server must use a static IP address.

Linux server's IP address (for example, 10.1.1.123): _____._____ ._____._____
Hostname (for example, myserver): _______________________
IMPORTANT: When installing the operating system, specify only the hostname. Do not include the DNS context with the name (for example, myserver.mycompany.com).
DNS context of hostname (for example, mycompany.com): ______________________
Subnet mask (for example, 255.255.255.0): _____._____._____._____
Default gateway (for example, 10.1.1.1): _____._____._____._____
Primary DNS server (for example, 10.1.1.2): _____._____._____._____

Disk Partitions

Table 2 presents guidelines for setting up disk partitions on your NNLS server.

Table 2. Partition Requirements

Partition	Minimum Disk Space	Other Considerations
/boot	*	* See the documentation for your chosen operating system.
/swap	*	* This should normally equal twice the RAM installed on your server up to 1 GB. For more information, see the documentation for your chosen operating systerm.
/	*	* The simplest partitioning method is to include all remaining disk space in this partition. Space for the subpartitions (/var, /opt, /usr, /etc, /home) is automatically available as the partitions expand. If you choose to define the partitions shown in the following rows (/var, /opt, and /usr), you should define this partition last and allocate all unused disk space to it.
/var	350 MB	If you define this partition separately and you plan to install Novell^® iFolder^®, be aware that iFolder user data is stored in this partition by default.
/opt	250 MB
/usr	310 MB

Firewall

Table 3 Shows the default ports used by NNLS. If you plan to use different ports for any listed items, you might want to note that in the table. This information is provided for integrating NNLS with your firewall.

Existing Apache Web Server

If the server where you install NNLS is already running an Apache Web server, the NNLS installation will disable the server and shut it down. It will not, however, uninstall the server.

The Apache Web server installed with NNLS must use the standard ports 80 and 443. The server's configuration files are installed to /etc/opt/novell/httpd/ and its document root is set to /var/opt/novell/httpd/htdocs.

If you want to run the previously installed Apache server in addition to the NNLS Apache server, you must change the ports it uses, re-enable it to run when the system boots, and restart it.
