Configuring Open Source Private Cloud

Asked By maryann carey 20 points N/A Posted on - 10/28/2011

I am doing a research on setting up and operating a private cloud using Open Source Cloud Computing software. This is less expensive than hiring a cloud hosting company. And also, we don’t have enough security issues in any case. So I am seeking your help here.

I need the steps in configuring an Open Source private cloud, the installation procedures for different servers and client and all the requirements needed.

 

Thank you in advance.

Configuring Open Source Private Cloud

These are steps below I found helpful to set up.

Step 1: Prepare a raw Ubuntu OS system. 

 

Install Ubuntu 9.04 on a machine. Select ssh server to be installed on the machine by default, so we can connect to machine remotely.

 

Step 2: Install postfix. 

 

Postfix is a mail server. Eucalyptus sends mails to users that are added by admin on Eucalyptus web interface. So we install postfix that Eucalyptus will use as mail server.

 

Steps to install postfix and to setup configurations and testing successful Postfix installation

 

Command# apt-get install postfix

 

Set configurations

 

Command# sudo dpkg-reconfigure postfix

 

Set following parameters with given values.

 

General type of mail configuration: Internet Site

 

NONE doesn't appear to be requested in current config

 

System mail name: server1.example.com

 

Root and postmaster mail recipient: <admin_user_name> (Optional)

 

Other destinations for mail: server1.example.com, example.com, localhost.example.com, localhost

 

Force synchronous updates on mail queue?: No

 

Local networks: 127.0.0.0/8

 

Yes doesn't appear to be requested in current config

 

Mailbox size limit (bytes): 0

 

Local address extension character: +

 

Internet protocols to use: all

 

Test postfix installation

 

Command# EHLO localhost

 

Mail from: root@localhost

 

Rcpt to: [email protected]

 

Data

 

Subject: your sub (press enter twice)

 

Type your message and finish with "." then Enter

 

Finish with "Quit"

 

Check your mail (if received your mail is working)

 

Step 3 Install Cloud and Cluster controller

 

Install the packages provided by Ubuntu, all the dependencies will be installed automatically by package manager.

 

Command# apt-get install eucalyptus-cloud eucalyptus-cc

 

Step 4 Install dhcp server

 

Install the DHCP server which is used by eucalyptus for assigning the IPs to instances. DHCP server should not be in running state and set the DHCP server not to run when system is booted up again.

 

Command# apt-get install dhcp3-server

 

Command# /etc/init.d/dhcdbd stop

 

Command# update-rc.d -f dhcdbd remove

 

Set the DHCP server path in the eucalyptus config file '/etc/eucalyptus/eucalyptus.conf'

 

VNET_DHCPDAEMON="/usr/sbin/dhcpd3"

 

Step 5 Eucalyptus configuration

 

Set the static mode for Eucalyptus so that Eucalyptus uses IP's from the pool of IP's provided in the config file and use the machine addresses provided along with IPs.

 

Configuration file for eucalyptus is '/etc/eucalyptus/eucalyptus.conf'

 

Open /etc/eucalyptus/eucalyptus.conf and set the following parameters

 

VNET_INTERFACE="peth0"

 

VNET_BRIDGE="eth0"

 

Locate 'kvm' and replace to 'xen'

 

Locate VNET_MODE="SYSTEM" and disable it

 

Locate VNET_MODE="STATIC" and enable it

 

Add machine and IPs for instances to be used and change the network setting to current network settings.

 

VNET_MODE="STATIC"

 

VNET_SUBNET="192.168.145.0"

 

VNET_NETMASK="255.255.255.0"

 

VNET_BROADCAST="192.168.145.255"

 

VNET_ROUTER="192.168.145.1"

 

VNET_DNS="192.168.150.42"

 

VNET_MACMAP="AA:DD:11:CE:FF:ED=192.168.145.73 AA:DD:11:CE:FF:EE=192.168.145.75

 

AA:DD:11:CE:FF:EF=192.168.145.77"

 

Step 6 Other configurations

 

Edit : /usr/share/eucalyptus/gen_libvirt_xml

 

Locate all 'sda' to 'xvda'

 

Edit : /etc/xen/xend-config.sxp

 

(xend-http-server yes)

 

Gateway = 192.168.145.1

 

Netmask = 255.255.255.0

 

Broadcast = 192.168.145.255

 

Step 7 Reboot the system to take effect

 

Step 8 Cloud configurations

 

Once Eucalyptus front end has been installed, we can use the Eucalyptus web interface and setup cluster and set other parameters.

 

Eucalyptus cloud web URL: https://<front end ip>:8443/

 

Under configuration tab add cluster name

 

Set host to 'localhost'

 

Create kernel and ramdisk images and set in eucalyptus site. (Procedure to create images will be described later in the page)

 

Restart the Eucalyptus daemon to take effect.
