300 Part III . Choosing and Installing a Linux Distribution Servers A Linux server installation generally consists of only the minimum set of packages required to provide the service for which it was designed. In particular, this means that servers do not usually have a graphical interface installed. Server hardware is generally more expensive than workstation hardware, although you can still run smaller servers on less-expensive desktop hardware. If you are planning to store important data on your server, then you will want to look into a RAID array for storage. A number of inexpensive ATA RAID controllers work well under Linux. More information about ATA RAID compatibility is available at http://linux mafia.com/faq/Hardware/sata.html and http://ibiblio.org/pub/ Linux/docs/HOWTO/other-formats/html_single/Hardware-HOWTO.html #IDERAID. Higher-end servers will, of course, require more expensive hardware. In applications such as mail servers where you will have a lot of disk activity, plan on splitting the disk-intensive tasks across multiple arrays. When it comes to CPU and RAM, more of both is good, but most applications benefit more from extra RAM than they do from multiple CPUs. Running the Installer The Debian installation process consists of two stages. Stage 1 The first stage boots from the installation medium (generally a CD); configures hardware drivers, disk partitions, and file systems; and then copies a set of essential packages known as the base system. Here s the procedure: 1. Boot the CD that comes with this book and type debian to begin the installation from the initial boot screen. 2. After the installer has finished booting, you are presented with the series of menus that make up the installation process. Use the arrow keys to navigate through the menus and select your language, region, and keyboard mapping. 3. Depending on whether a network card was detected in your system, you may be prompted to set up the network for your new Debian system. By default, the installer attempts to use DHCP to configure the IP addressing on the network card. If you configured it to skip DHCP, or if the DHCP configuration fails, you are prompted to enter the IP address, network mask, default gateway, and DNS server addresses. Note
