Target deployment for production will be the Amazon AWS cloud stack executing on top of Ubuntu Amazon Machine Image. Currently foreseen is an AMI for the Ubuntu Server 12.10 of architecture AMD 64bit. Any
Each AMI is a machine template from which you can instantiate new servers. Each AMI has its own unique ID
The goal is to use a standard template offered by Amazon via EC2(refer to Amazon AMI Locator and have a highly automated deploying process on top of that for installing all required software, as well as the Cloudburo platform and apps.
For the automation we will take Salt. Salt is a
It was developed in order to bring the best solutions found in the world of remote execution together and make them better, faster, and more malleable. Salt accomplishes this through its ability to handle large loads of information, and not just dozens but hundreds and even thousands of individual servers quickly through a simple and manageable interface.
The following setup is done using the Oracle VM VirtualBox Manger on a Max OSX system.
This is straighforward, download from the Ubuntu Homepage a up-to-date version (ISO format) a Ubuntu Server, e.g.
ubuntu-12.10-server-amd64.iso. Create a new guest system in thea Virtualbox (wizard driven) and do a default installation of the Ubuntu Server (incluede the openssh package as a minimum).
After having completed these steps you have your Ubuntu guest system running which is connected to the Internet only (supposing that you did a default installation), this means the host system (Mac) doesn’t know and can’t access the guest and vice versa. In order to enable that you have to configure a host to guest network interface.
Go to top menu Virtual Box -> Preferences select the tab Network and add a new Host-only Network
“Screenshot Host-only Network” %}
Open Virtual Box Settings Menu and select Network tab. Add a second network adapter (Host-only Adapter). Refer to screenshot (in your setup that would Adapter 2, for the Advanced part take the default). Select the corresponding Host-only Adapter.
For our example below we have it configured to an adapter called vboxnet1.
My host is a OSX based iMac machine. Having now setup the additional network adapters I could check it’s configuration on the host, by running
iMac:~ Felix$ ifconfig vboxnet1 vboxnet1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 0a:00:27:00:00:01 inet 192.168.57.1 netmask 0xffffff00 broadcast 192.168.57.255
My assumption was that I now can login via ssh via 192.168.57.1, which is also pingable. Doing a ssh against this address will result in a ssh login to your host system (and not the guest one).
Obviously this Host-only Adapter
vboxnet1 cannot be used as access point to the Ubuntu guest system. You have to configure another adapter in the Ubuntu Guest system which is in the IP range of the
vboxnet1. e.g. you can define for it the IP address
Login to the Ubuntu guest system and open the following interface configuration file
[email protected]:~$ sudo vi /etc/network/interfaces
The file will contain something like this
# 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 dhcp
Now add a new
eth1interface definition to the end of the file and save id
auto eth1 iface eth1 inet static address 192.168.57.10 netmask 255.255.255.0
Having done that bring up the new interface.
[email protected]:~$ sudo ifup eth1
Now you can directly login from the Mac machine via ssh to the Ubuntu guest system
iMac:~ Felix$ ssh [email protected] [email protected]'s password: Welcome to Ubuntu 12.10 (GNU/Linux 3.5.0-17-generic x86_64) Last login: Sun Feb 3 01:31:12 2013 from 192.168.57.1 [email protected]:~$
I did a same setup with a RedHat Enterprise Linux system, where the interfaces are defined a little bit differently. So go to the following directory
Add a new file ifcfg-eth1 and put the following content (adjust your ip address to the range of your vboxnet
DEVICE=eth1 TYPE=Ethernet ONBOOT=Yes NM_CONTROLLED=yes BOOTPROTO=static IPADDR=192.168.58.10 NETMASK=255.255.255.0
Run the following command
service network restart
That’s it you should now have a ssh connection to your RedHat VM.
Similar steps necessary as above described:
[[email protected] network-scripts]$ more ifcfg-eth2 DEVICE=eth2 HWADDR=08:00:27:FF:80:FD TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=static IPADDR=188.8.131.52 NETMASK=255.255.255.0
