鐵人賽要進入尾聲了，

希望可以再這幾天的課程中，把Openstack剩下的安裝介紹完成

今天剩下的是我們來設置有關虛擬機器上網的路徑

我們暫時性以小規模的狀態來使用的虛擬機器的網路，

所以我們用Nova的network module 而不是選用先前介紹的Neutron專案

設定Nat for 192.168.1.0 於 br0裝置上

1. Create Nova Network on Controller node

nova network-create vmnet --fixed-range-v4=192.168.1.0/24 --bridge-interface=br0

9. Launch an instance on Controller node

nova secgroup-add-rule default tcp 22 22 0.0.0.0/0

nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0

ssh-keygen

nova keypair-add --pub_key ~/.ssh/id_rsa.pub mykey

nova flavor-list

nova image-list (得到 [Image_ID]填入下方)

nova boot --flavor 1 --key_name mykey --image [Image_ID] --security_group default cirrOS

nova list (得到 [VM_IP]填入下方)

ssh cirros@[VM_IP]

這邊我們來設定安裝 Cinder 這個 for vm使用的 block-storage

20. Install Cinder Central Service on Controller node

apt-get install -y cinder-api cinder-scheduler

nano /etc/cinder/cinder.conf (add)

[DEFAULT]

rpc_backend = cinder.openstack.common.rpc.impl_kombu

rabbit_host = [Controller_IP]

rabbit_port = 5672

rabbit_userid = guest

rabbit_password = RABBIT_PASS

glance_host = [Controller_IP]

[database]

connection = mysql://cinder:CINDER_DBPASS@[Controller_IP]/cinder

[keystone_authtoken]

auth_uri = http://[Controller_IP]:5000

auth_host = [Controller_IP]

auth_port = 35357

auth_protocol = http

admin_tenant_name = service

admin_user = cinder

admin_password = CINDER_PASS

mysql -u root -p

CREATE DATABASE cinder;

GRANT ALL ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'CINDER_DBPASS';

GRANT ALL ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'CINDER_DBPASS';

su -s /bin/sh -c "cinder-manage db sync" cinder

keystone user-create --name=cinder --pass=CINDER_PASS --email=cinder@example.com

keystone user-role-add --user=cinder --tenant=service --role=admin

keystone service-create --name=cinder --type=volume --description="Cinder Volume Service"

keystone endpoint-create --service-id=$(keystone service-list | awk '/ volume / {print $2}') --publicurl=http://[Controller_IP]:8776/v1/%\(tenant_id\)s --internalurl=http://[Controller_IP]:8776/v1/%\(tenant_id\)s --adminurl=http://[Controller_IP]:8776/v1/%\(tenant_id\)s

keystone service-create --name=cinderv2 --type=volumev2 --description="Cinder Volume Service V2"

keystone endpoint-create --service-id=$(keystone service-list | awk '/ volumev2 / {print $2}') --publicurl=http://[Controller_IP]:8776/v2/%\(tenant_id\)s --internalurl=http://[Controller_IP]:8776/v2/%\(tenant_id\)s --adminurl=http://[Controller_IP]:8776/v2/%\(tenant_id\)s

service cinder-scheduler restart

service cinder-api restart

53. Install Cinder LVM Volume Service on Controller nodes

apt-get install -y lvm2 cinder-volume

dd if=/dev/zero of=/root/cinder-volumes.img bs=1M seek=100000 count=0

losetup /dev/loop0 /root/cinder-volumes.img (加載裝置)

(可加到/etc/rc.local)

losetup -a

pvcreate /dev/loop0

vgcreate cinder-volumes /dev/loop0

vgdisplay

nano /etc/lvm/lvm.conf

devices {

filter = [ "a/loop0/","r/.*/"]

}

service cinder-volume restart

service tgt restart

68. Installing the OpenStack Dashboard

apt-get install -y apache2 memcached libapache2-mod-wsgi openstack-dashboard

apt-get remove -y --purge openstack-dashboard-ubuntu-theme

nano /etc/openstack-dashboard/local_settings.py

OPENSTACK_HOST = "[Controller_IP]"

ALLOWED_HOSTS = ['localhost', '[Controller_IP]','[Controller_Hostname]']

service apache2 restart

service memcached restart

明天將邁入最後一天，介面操作！！
