Jump Server ConfigurationΒΆ

Jump server install procedures are maintained by each installer project. Addional Jump server configuraton BKMs will be maintained here. The below install information was used for Fuel however may be outdated (please refer to Fuel Installer documents).

Procedure

  1. Obtain CentOS 7 Minimal ISO and install
wget http://mirrors.kernel.org/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-1503-01.iso
  1. Set parameters appropriate for your environment during installation
  2. Disable NetworkManager
systemctl disable NetworkManager
  1. Configure your /etc/sysconfig/network-scripts/ifcfg-* files for your network
  2. Restart networking
service network restart
  1. Edit /etc/resolv.conf and add a nameserver, for example 8.8.8.8
echo nameserver 8.8.8.8 >> /etc/resolv.conf
  1. Install libvirt & kvm
yum -y update yum -y install kvm qemu-kvm libvirt systemctl enable libvirtd
  1. Reboot:
shutdown -r now
  1. Configure SSHD

If you wish to avoid annoying delay when use ssh to log in, disable DNS lookups:

When UseDNS is existed in the config file, update it:

sed -i -e 's/^#*UseDNS\ \+yes/UseDNS no/' /etc/ssh/sshd_config

or append the setting when not existed:

echo UseDNS no >> /etc/ssh/ssd_config

Disable Password Authenticaion for security:

sed -i -e 's/^#PasswordAuthentication\ \+yes/PasswordAuthentication no/' /etc/ssh/sshd_config

If you want to disable IPv6 connections, comment IPv6 ListenAddress and change AddressFamily to inet:

sed -i -e 's/^ListenAddress\ \+::/#ListenAddress ::/' /etc/ssh/sshd_config sed -i -e 's/^AddressFamily\ \+any/AddressFamily inet/' /etc/ssh/sshd_config

  1. Restart sshd
systemctl restart sshd
  1. Install virt-install
yum -y install virt-install
  1. Visit artifacts.opnfv.org and D/L the OPNFV Fuel ISO
  2. Create a bridge using the interface on the PXE network, for example: br0
brctl addbr br0
  1. Make a directory owned by qemu:

mkdir /home/qemu; mkdir -p /home/qemu/VMs/fuel-6.0/disk

chown -R qemu:qemu /home/qemu

  1. Copy the ISO to /home/qemu

cd /home/qemu

virt-install -n opnfv-2015-05-22_18-34-07-fuel -r 4096 --vcpus=4 --cpuset=0-3 -c opnfv-2015-05-22_18-34-07.iso --os-type=linux --os-variant=rhel6 --boot hd,cdrom --disk path=/home/qemu/VMs/mirantis-fuel-6.0/disk/fuel-vhd0.qcow2,bus=virtio,size=50,format=qcow2 -w bridge=br0,model=virtio --graphics vnc,listen=0.0.0.0

  1. Temporarily flush the firewall rules to make things easier:
iptables -F
  1. Connect to the console of the installing VM with your favorite VNC client.
  2. Change the IP settings to match the pod, use an IP in the PXE/Admin network for the Fuel Master
