COMMENTED COMMAND LINE LISTING FOR CREATING VM :


1.Installation of Openstack CLI in our system by using python:

> apt install python-openstackclient

2. To export the environment by downloading the .sh file:

>  source cc1718-group09-openrc.sh

3. Openstack is now running:

(openstack)

4.Create ssh key without paraphrase

> ssh-keygen -N”” -f~/.ssh/cc1718-group09

5.Load the public key to the server:

> openstack keeper create —public-key~/.ssh/cc1718-group09

6. Creation of the default security group:

> (openstack) security group rule create  grp09 —proto tcp --dst-port 22:22 default

> (openstack) security group rule create grp09 --proto icmp

7.Create server with configuration “Cloud Computing” and image “ubuntu 16.04” with the default security group and ssh key and the ssh which was created with the network ccnet :

> (openstack) server create --image ubuntu-16.04 --flavor 'Cloud Computing' --security-group default --key-name cc1718-group09 —network ccnet cc1718-group09

8.Delete unused floating ip :

>floatingip=‘openstack floating ip list -status DOWN|awk’{print$4}’|grep’^[[:digit:]]’|tail -n 1’

9.Adding floating ip to the VM Instance :

>(openstack) server add floating ip cc1718-group09 $floatingip

10.Copying the files from local system to VM :

> scp -i ~/.ssh/cc1718-group09 memsweep.sh memsweep.c linpack.sh linpack.c benchmark.sh
ubuntu@$floatingip:~

11.Connect to the VM Instance via ssh:

>ssh -i ~/.ssh/cc1718-group09 ubuntu@$floatingip

/////LOGGED IN THE VM INSTANCE//////

Making the permission of shell script as executable :
chmod 0777 memsweep.sh linpack.sh benchmark.sh

Installation of dependencies :
sudo apt-get install gcc fio 

adding cronjob for user ubuntu :
0 */4 * * *  ./benchmark.sh
