Installing VMWare Tools

After reboot, log in using the account created during install.

Note: in our build the network was configured using dhcp. If this is not the case in your environment you will need to set a static ip address. See Ubuntu Configure Static IP Address

The first thing we will do after install is update the system. Enter the following command to update the apt database:

sudo apt-get update

If prompted for sudo password enter your password. Next type the following to upgrade your system:

sudo apt-get upgrade

The following packages are required before installing VMWare Tools:

sudo aptitude install build-essential linux-headers-$(uname -r)

Then enter:

sudo aptitude install psmisc

Now we are ready to install VMWare tools. In Workstation click on VM and click Install VMWare Tools

Next, enter the following command in Jeos to mount the CD

mount /media/cdrom0

Change directories to the /tmp directory

cd /tmp

Enter the following to unzip the VMWare Tools files

tar xvzf /media/cdrom0/VMwareTools*.gz

Enter the following to run the VMWare Tools install script:

sudo vmware-tools-distrib/vmware-install.pl

Press Enter to accept all defaults

When install finishes clean up files

rm -rf *

Install Application(s)

At this point install whatever applications will be included in this virtual appliance. In this build we will be installing Red5.

Please see Building a Red5 Virtual Appliance on Jeos for installing Red5.

Preparing Virtual Appliance For Shipping

Create the following directories:

sudo mkdir /etc/opt/va
sudo chmod 777 /etc/opt/va
sudo mkdir /opt/va/bin

The following script will prompt the user to set new password and ip address. Add the following script to the directory /opt/va/bin

echo "Welcome to your new Appliance"
echo "--------------------------------------------------"
echo "Please Enter a new password:"
passwd
while true; do
 read -p "Do you wish to configure a static ip address Y/N?" yn
 case $yn in
 [Yy]* ) echo "Enter New IP Address:";
 read ip;
 echo "Enter Subnet Mask:"
 read netmask;
 echo "Enter default gateway:";
 read gateway;
 echo "Enter Primary DNS Server:";
 read dns1;
 echo "Enter Secondary DNS Server:";
 read dns2;

sudo cp /etc/opt/va/network_setup /etc/opt/va/new_settings
sudo chmod 777 /etc/opt/va/new_settings
sudo echo "address $ip" >> /etc/opt/va/new_settings
sudo echo "netmask $netmask" >> /etc/opt/va/new_settings
sudo echo "gateway $gateway" >> /etc/opt/va/new_settings
sudo cp /etc/opt/va/new_settings /etc/network/interfaces
sudo cp /etc/opt/va/dns_setup /etc/opt/va/new_dns
sudo chmod 777 /etc/opt/va/new_dns
sudo echo "nameserver $dns1" >> /etc/opt/va/new_dns
sudo echo "nameserver $dns2" >> /etc/opt/va/new_dns
sudo cp /etc/opt/va/new_dns /etc/resolv.conf
sudo /etc/init.d/networking restart
 break;;
 [Nn]* ) exit;;
 * ) echo "Please answer yes or no.";;
 esac
done

 

Next, edit the /etc/bash.bashrc file adding the following to the end

if [ ! -e /etc/opt/va/ran_setup ]; then
/opt/va/bin/initial_config
sudo touch /etc/opt/va/ran_setup
fi

Finally, add the following file to /etc/opt/va

network_setup

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static

Create a blank file named dns_setup in /etc/opt/va

Finally, enter the following to clear the history and poweroff the system

history -c

sudo poweroff
