  • Methods of installation


Hardware l.jpg
Hardware

Hardware Compatibility List (HCL):

  • Red Hat http://www.redhat.com/hardware

Server design l.jpg
Server design

Significant issues:

  • Stability

  • Availability

  • Performance


Design decision l.jpg
Design decision

  • The most significant design decision to make when managing a server configuration is not technical, but administrative.

  • The server designed should have a good environment.


Design decision7 l.jpg
Design decision

Server design should not be user friendly:

  • No multimedia tools.

  • No sound card support.

  • No distracting web browsers.


Physical safety of servers l.jpg
Physical safety of servers

  • Keep servers in a separate, physically secure room.

  • Restrict server access for non-administrative personnel only through the Network.

  • Install a battery backup.


Improve server situation l.jpg
Improve server situation

  • Avoid starting X Window until required.

  • Determine what functions you want the server to perform and disable the other functions.

  • Linux allows tailoring of the kernel.


Uptime l.jpg
Uptime

Uptime command provides:

  • Duration of the system since its last boot.

  • Number of users currently logged in.

  • Load the system is experiencing.


Dual booting issues l.jpg
Dual-Booting issues

  • Windows 95 or Windows 98 – use the fips.exe.

  • Windows NT – move some of the data around manually to free a partition.


Dual booting issues12 l.jpg
Dual-Booting issues

  • To repartition a system that has already had Windows 9x/NT installed onto it –use third party software like “Partition Magic”.
