Network Topology

Prepare VMs

Fedora: Using udev rename, networkManager

Fix 

  systemctl restart NetworkManager.service

Fedora: Fix udev, NetworkManager

Disable systemd-udevd remane network iface

Approach 1: 

   vi /boot/grub/grub.conf
   Pass biosdevname=0 to kernel command line

Approach 2: You may continue to write rules in /etc/udev/rules.d/70-persistent-net.rules to change the device names to anything you wish. Such will take precedence over this physical location naming scheme. Such rules may look like: 

 SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:11:22:33:44:55", ATTR{type}=="1", KERNEL=="eth*", NAME="public"

Disable NetworkManager and enable network 

systemctl stop NetworkManager.service
systemctl disable NetworkManager.service
rm /etc/sysconfig/network-scripts/ifcfg-enp5s0f1

systemctl start network.service
systemctl enable network.service

Fedora: firewalld

Disable firewalld 

  systemctl stop firewalld
  systemctl disable firewalld
  yum install iptables-services
  # Create this below file, otherwise starting iptables will fail
  touch /etc/sysconfig/iptables
  systemctl enable iptables && systemctl start iptables

Prepare Installation on each VM

Host:

vim /etc/hosts

192.168.200.209	controller
192.168.200.212	compute
192.168.200.215	network

Fedora Network:

There are 3 networks 

# The primary network interface - VirtualBox NAT connection
# (VirtualBox Network Adapter 1)
auto eth0
iface eth0 inet dhcp

# VirtualBox vboxnet0 - OpenStack management network
# (VirtualBox Network Adapter 2)
auto eth1
iface eth1 inet static
address 10.10.10.51
netmask 255.255.255.0

# VirtualBox vboxnet2 - OpenStack API network
# (VirtualBox Network Adapter 3)
auto eth2
iface eth2 inet static
address 192.168.100.51

Maven:

yum install maven -y
# java etc also installed

sudo cd /opt
wget http://apache.openmirror.de/maven/maven-3/3.2.3/binaries/apache-maven-3.2.3-bin.tar.gz
tar -xvzf apache-maven

JAVA_HOME

vim .bash_profile
    
# User specific environment and startup programs
export M2_HOME=/opt/apache-maven-3.2.3
export M2=$M2_HOME/bin
export MAVEN_OPTS='-Xms256m -XX:MaxPermSize=1024m -Xmx1024m'

export JVM_ROOT=/usr/lib/jvm
export JAVA_HOME=$JVM_ROOT/java

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH=$JAVA_HOME:$M2:$PATH
  source .bash_profile

On other nodes 

  sudo scp -rp root@controller:/opt/apache-maven* /opt/
  scp -rp fedora@controller:~/.bash_profile ./.bash_profile
  source .bash_profile

Misc

sudo yum install python-pip.noarch
pip install git-review
