This article dedicated to developer ,project leaders , Cloud architects . I am gonna explain how to setup a cloud using command line .This useful for newbies to cloud and UNIX both !
I am using a Ubuntu 11.10 (64 bit server ), so lets play with shell !!
for setting up a prefect cloud you need minimum two network NIC on your hardware , a lot of public Ip . :)
But i am setting it on one network it on one NIC hardware , with One IP (students and tester can with way those have less resources ) :)
We are setting up it with
open-stack .
Official website of this document is below:
ubuntu 11.10 environment deployment, select the network mode FLATDHCP
public interface: eth0 used to connect to the user
private interface: eth1 do bridge br100, used, and other nodes, keystone, glance, volume and other connections
Minimum installed Ubuntu
Remember to open-ssh installed, where we have
established a common user open-stack
Giving it the NOPASSWD sudo
privileges, so easy to operate behind
$ Sudo apt-get update // (apt update about the tree)
$ Sudo apt-get install bridge-utils // ( installed bridge components )
Configure the network
$ vi / etc / network / interfaces //(gksudo also can be used instead of vi for GUI Fans )
auto eth0
iface eth0 inet static
address 192.168.200.21
netmask 255.255.255.0
network 192.168.200.0
broadcast 192.168.200.255
gateway 192.168.200.10
auto br100
iface br100 inet static
bridge_ports eth1
bridge_stp off
bridge_maxwait 0
bridge_fd 0
address 10.200.200.2
netmask 255.255.255.0
$ Sudo / etc / init.d / networking restart
Initial preparatory work to do, the next step is to install on nova, glance and other components
$ Sudo apt-get install-y rabbitmq-server // (install the MQ message components )
$ Sudo apt-get install-y python-greenlet python-mysqldb // (install Python dependencies )
Next, install the various nova components and dependencies
$ Sudo apt-get install nova-volume nova-vncproxy nova-api nova-ajax-console-proxy
$ Sudo apt-get install nova-doc nova-scheduler nova-objectstore
$ Sudo apt-get install nova-network nova-compute
$ Sudo apt-get install glance
Installation euca2ools and unzip
$ Sudo apt-get install-y euca2ools unzip
Next we install the database, I chose MYSQL, PostgreSQL actually personally feel better
$ Sudo su - to root user to change
# MYSQL_PASS = nova nova set mysql database password and the password
# NOVA_PASS = notnova here nova and notnova modified according to their definitions
# Cat <<MYSQL_PRESEED | debconf-set-selections
> Mysql-server-5.1 mysql-server/root_password password $ MYSQL_PASS
> Mysql-server-5.1 mysql-server/root_password_again password $ MYSQL_PASS
> Mysql-server-5.1 mysql-server/start_on_boot boolean true
> MYSQL_PRESEED
# Apt-get install-y mysql-server
# Exit exit root environment
$ Sudo sed-i 's/127.0.0.1/0.0.0.0/g' / etc / mysql / my.cnf modify my.cnf configuration file
$ Sudo service mysql restart
$ MYSQL_PASS = nova in the general user environment variable to the password once again set about
$ NOVA_PASS = notnova
$ Sudo mysql-uroot-p $ MYSQL_PASS-e 'CREATE DATABASE nova;'
// (to create a
name for the ova of the database, I recommend that new users nova's
name, if here for another name, then the configuration file in the nova
which also need to change )
$ Sudo mysql-uroot-p $ MYSQL_PASS-e "GRANT ALL PRIVILEGES ON *.* TO
'Nova'@'%' WITH GRANT OPTION; "
$ Sudo mysql-uroot-p $ MYSQL_PASS-e "SET PASSWORD FOR 'nova'@'%' =
PASSWORD ('$ NOVA_PASS'); "
This point. nova, glance of the installation completed, next is the configuration
nova configuration
$ Sudo vi / etc / nova / nova.conf

$ Sudo vi / etc / glance / glance-api.conf
// (In this file without using keystone of the present case, according to
your needs, modify filesystem_store_datadir parameter to specify the
directory you need to store images, Dangran are the main users have
Gaicheng glance )
$ Sudo vi / etc / glance / glance-registry.conf
// (This file can be selected to modify sql_connection parameter to specify your database. Of course you can not change.
If you want to modify, use mysql which database to ensure that the mysql which established a corresponding database )
sql_connection = mysql: / / nova: notnova @ localhost / glance this is
my configuration, I created a glance in the mysql database
$ Sudo chown-R root: nova / etc / nova to change / etc / nova's owner
$ Sudo chmod 640 / etc / nova / nova.conf
Restart all services
$ Sudo restart libvirt-bin
$ Sudo restart nova-network
$ Sudo restart nova-compute
$ Sudo restart nova-api
$ Sudo restart nova-objectstore
$ Sudo restart nova-scheduler
$ Sudo restart glance-registry
$ Sudo restart glance-api
Note: We do not have from the nova-volume, because although we
installed the volume, but the volume needs to use a separate vg, we have
not configure the volume, so get up.
There may be network services and can not compute it, do not worry about being first
Next, we do configure the operating environment of the nova
$ Sudo nova-manage db sync
nova-manage user admin <user_name> where we can create a user, such as
$ Sudo nova-manage user admin test, create a successful return on the screen like:
export EC2_ACCESS_KEY = d6aa7747-4324-4abc-9604-4f7d6a2f8f3f
export EC2_SECRET_KEY = 2b204b75-da2d-47b8-ba7a-611d71f0ecbf
nova-manage project create <project_name> <user_name> create a project, we built that are just users, such as:
$ Sudo nova-manage project create test-proj test
nova-manage network create - help create an instance of the network, such as:
$ Sudo nova-manage network create - label = test-net - fixed_range_v4 = 10.200.200.0/24 - num_network = 1 - network_size = 256
Services have failed to start again
$ Sudo start nova-network
$ Sudo start nova-compute
$ Sudo start nova-scheduler
In addition, since each service, the best look at the log, such as sudo
tail-f / var / log / nova / nova-network to determine there is no
error, you can also use the ps aux | grep [n] ova-network to confirm the
service is not open.
If the starting service fails, you confirm that a good reason to modify
a good future, need to use sudo start to play instead of sudo restart
Well. This computing environment, we deployed the. We can look at the state command
$ Sudo nova-manage service list
$ Sudo nova-manage network list
Etc.
Next, create a certificate, to facilitate the tool we use euca
$ Cd
$ Mkdir creds
$ Sudo nova-manage project zipfile test-proj test creds / novacreds.zip
$ Unzip creds / novacreds.zip-d creds /
$ Source creds / novarc
OK, done, we can use the tool to look at
$ Euca-describe-availability-zones verbose
VAILABILITYZONE nova available
AVAILABILITYZONE | - Nova-test
AVAILABILITYZONE | | - Nova-network enabled :-) 2011-10-17 04:45:44
AVAILABILITYZONE | | - Nova-compute enabled :-) 2011-10-17 04:45:45
AVAILABILITYZONE | | - Nova-scheduler enabled :-) 2011-10-17 04:45:46
So far, successfully enabled services.
When you find that service is not working, use ps aux | grep nova check
services are not open, and the need for detailed observations / var /
log / nova / directory log files for each service, in order to obtain
further information.
Then we can use kvm to create a mirror image
$ Sudo apt-get install kvm-pxe installation about this, otherwise there will be time to run kvm warning
$ Kvm-img create-f raw server.img 5G
$ Sudo kvm-m 1024-cdrom rhel5.iso-drive file = server.img, if = virtio, index = 0-boot d-net nic-net user-nographic-vnc: 0
Here we use rhel5(Redhat) the iso, after running this command, you can use vnc
to connect the machine to connect to your server: ssvncviewer
192.168.200.21: 0
Open vnc you can see the installation interface After the installation,
the following paragraph written rhel mirror / etc / rc.local the
beginning of the
depmod-a
modprobe acpiphp
# Simple attempt to get the user ssh key using the meta-data service
mkdir-p / root / .ssh
echo>> / root / .ssh / authorized_keys
curl-m 10-s
http://169.254.169.254/latest/meta-data/public-keys/0/openssh-key | grep
'ssh-rsa'>> / root / .ssh / authorized_keys
echo "AUTHORIZED_KEYS:"
echo "************************"
cat / root / .ssh / authorized_keys
echo "************************"
Save and exit, so that image on the well
Upload images using glance
$ Glance - verbose add name = "rhel5" disk_format = raw is_public = true <server.img
You should also observe the / var / log / glance / registry and the log api
$ Glance index to see a list of mirrors
Start your instance
$ Euca-describe-images
You can now view the image, output similar to the
IMAGE ami-00000003 server.img
Remember this image here ami-000000003 No.
$ Euca-run-instances-t m1.tiny ami-00000003 start an instance of ami-00000003 image
-T specifies the type of instance, provides the type of cpu, memory, disk size, etc..
Watch / var / log / nova / nova-api.log nova-scheduler.log,
nova-compute, nova-network.log of output, but you can also use vnc to
connect serverip: 0 look at the console instance
With the command $ euca-describe-instances to see your current instance
of the first instance will be relatively slow start because of the need
to copy the image from a glance under the instance directory to the
nova
Conclusion As the nova is currently growing fast, diablo release
version of the function of some of the requirements to be completed
daily. But the development version of the nova can be better combined with keystone, novaclient, dashboard and some other projects. Makes openstack more robust.
Friends who are interested, you can use in a production environment
repo's installation, test development versions of the test environment. Since I use in a production environment install git development version. Therefore, a more complete integration of follow-up, I will develop versions of the form.
Of course, using the development version, then there will be more
trouble, but also have more fun and hands-on practice, to further
understand the mechanism of its working principle.
Looking for help /technical support !
