6.4 Deploy mgmt1 and Configure
The mgmt1 server is the catalyst for the rest of the environment. This system will host virtual
machines and become one node of a two node cluster which is covered in Configure High
Availability Environment. When installing this host, make sure to disconnect the SAN
storage or use the ignoredisk as a kernel option in the Kickstart profile for RHEL 6 hosts or
nostorage for RHEL5 so the operating system does not get installed on the external LUN.
Target System: mgmt1
1. Install Red Hat Enterprise Linux 6 (Reference a Red Hat Enterprise Linux 6 Admin
Guide Here – Follow best practices for Security)
• Include Clustering and Virtualization software groups when selecting software
components
• Set SELinux to permissive mode
• Enable the firewall leaving ports open for ssh, http, and https
2. Register the system with RHN if that has not been completed
1. Update the system via RHN
# yum update
3. Reboot into the new kernel if available
4. Install the bridge-utils package
# yum -y install bridge-utils
5. Make the following modifications to ifcfg-eth0 file (Configuring the Bridge)
6. This will create a bridge to allow the virtual machines to communicate with each other
directly.
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="none"
HWADDR="00:1A:64:76:00:00"
NM_CONTROLLED="yes"
ONBOOT="yes"
# IPADDR=10.16.139.20
# NETMASK=255.255.248.0
BRIDGE=rhcf
7. Copy ifcfg-eth0 to ifcfg-rhcf and make the following changes to the ifcfg-rhcf file
# cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-
scripts/ifcfg-rhcf
# cat /etc/sysconfig/network-scripts/ifcfg-rhcf
DEVICE="rhcf"
BOOTPROTO="none"
NM_CONTROLLED="yes"
ONBOOT="yes"
IPADDR=10.16.139.20
