Linux server installation on Dell iDRAC

 

In this article, we have just given the overview of the Linux installation on Dell iDRAC.

# Set iDRAC to DHCP

# Change iDRAC root password

– default: root:calvin

# Configure filesystem layout

– Make your default layouts

——————————————————————
rootvg rootvg_vol00 10G /

rootvg rootvg_vol01 10G /home

rootvg rootvg_vol02 14G /usr/openv

rootvg rootvg_vol03 10G /opt

rootvg rootvg_vol05 10G /var

N/A /dev/sda1 100M /boot

NOTE: The “/usr/openv” volume is only needed for NetBackup installation if needed.

# Configure Firewall

– Allow

– SSH
– NFS
– NTP (123 UDP)

# Set SELinux to “Passive”

# Configure Network Interfaces

– “/etc/sysconfig/network”

EXAMPLE:

NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=myserver
GATEWAY=10.1.4.56

NOTE: GATEWAY = Default Gateway

– “/etc/sysconfig/network-scripts/ifcfg-*”

EXAMPLE:

DEVICE=eth2
HWADDR=00:2B:31:88:AB:8C
BOOTPROTO=none
ONBOOT=yes
HOTPLUG=no
IPADDR=10.0.0.100
NETMASK=255.255.255.0
NETWORK=10.0.0.0
BROADCAST=10.0.0.255
TYPE=Ethernet

# Configure Host Routing

– Create “/etc/sysconfig/static-routes”

– Add the default route, and any other static routes that are needed to this file

EXAMPLE:

# Static Routes to add at boot

bond0 route add -host default netmask 255.255.255.0 gw 10.1.4.254
bond1 route add -host 10.4.68.0 netmask 255.255.255.0 gw 10.4.68.254

# Configure Hostname

– edit “HOSTNAME” value in “/etc/sysconfig/network”
– $ hostname [new hostname]
– Verify
$ hostname

# Configure DNS (“/etc/resolve.conf”)

search example.com
nameserver 192.168.2.1
nameserver 192.168.3.1

# Configure NTP (“/etc/ntp.conf”)

server 192.172.3.1
server 192.172.6.1

# Apply Hardening (See additional documentation)

– SSH
– Password Complexity
– Password Aging
– Services

# Set default run-level to “3”

– “/etc/inittab”

id:3:initdefault:
