從最底層基礎建設到軟體開發，無所不包的雲端(Openstack Day 21)

最後一天的稿了


中間面臨到 雙十連假 生病 重感冒 心情低落  但還是到最後一天了


今天就讓我們繼續翱翔於 Openstack 的 雲端中

Go to http://[Controller_IP]/horizon

讓我們連到你原先設定好的主機上

然後！！

快利用先前Day 26的實作操作筆記

export OS_USERNAME=admin

export OS_PASSWORD=ADMIN_PASS

來做登入

登入之後 我們一樣會看到先前介紹的

使用者的使用量的資訊

讓我們點選到instances 的頁面 來開設虛擬機器!!

這裡 需要調整的主要是 Flavor 與 os  image 的部份

當然別忘了開設虛擬機器名稱

建立完成 你就可以再介面上看到

你剛剛建立的虛擬機器 且 網路是依照你先前設定的 環境
於nova-network  的 192.168.1.x的網路中

點選到虛擬機器的 console 介面 應該就會看到先前安裝的novnc 的登入服務了

記得帳號密碼用:

cirros 與 cubswin:)

就可以體驗一下虛擬機器建完的速度 與 native 的主機使用操作差距

當然您也可以嘗試看看虛擬機器來額外加載一個volume 透過cinder service.

這邊就不截圖了

讓各位有自行操作與學習的空間


一連串的發文 總算到了底了。

這次的鐵人賽雖然沒有時間介紹  ezilla  與 ceph等 雲端上常用的opensource 專案

但沒關係，我們還有2015年的IT 鐵人

期待鐵人賽的修成T-shirt!!!!

打到這的時候，真的有種放下胸口重擔的感覺

完美的
Day 30. Ending

從最底層基礎建設到軟體開發，無所不包的雲端(Openstack Day 20)

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

2. 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 

3. 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

4. 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

5. 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！！

Day 29 Ending 

從最底層基礎建設到軟體開發，無所不包的雲端(Openstack Day 19)

由於Nova 的部分 比較複雜 將會分為幾天來做教學



首先 我們先需要一個Controller Node 來做虛擬機器的管理

所以，今天就讓我們先來安裝Controller node吧

1. Install Compute controller services on controller node

# apt-get install -y nova-api nova-cert nova-conductor nova-consoleauth nova-novncproxy nova-scheduler python-novaclient nova-compute-kvm python-guestfs nova-network

(若使用qemu，請改裝nova-compute-qemu，並修改nova.conf)

設定libguestfs0 : Create or update supermin appliance now? (是)

# rm /var/lib/nova/nova.sqlite

# dpkg-statoverride --update --add root root 0644 /boot/vmlinuz-$(uname -r)

# modprobe kvm_intel

# nano /etc/libvirt/qemu.conf (modify)

user = "root"

group = "root"

cgroup_device_acl = [

"/dev/null", "/dev/full", "/dev/zero",

"/dev/random", "/dev/urandom",

"/dev/ptmx", "/dev/kvm", "/dev/kqemu",

"/dev/rtc", "/dev/hpet","/dev/net/tun"

]

# service libvirt-bin restart

2. Configure Compute controller services on controller node

這代表著是 目前所有服務正常啟動中

Day 28 Ending !

從最底層基礎建設到軟體開發，無所不包的雲端(Openstack Day 18)

今天主要的安裝目標是將Glance Service 安裝完成，並且註冊一個image 

提供之後Nova Service 來做虛擬機器的開設

Step 1.      Installing the Image Service

# apt-get install -y glance python-glanceclient

Step 2.      Edit the Glance configuration files and paste ini middleware files

# nano /etc/glance/glance-api.conf  (modify)

auth_host = [Controller_IP]

auth_port = 35357

auth_protocol = http

admin_tenant_name = service

admin_user = glance

# mysql -u root -p

> CREATE DATABASE glance;

> GRANT ALL ON glance.* TO 'glance'@'%' IDENTIFIED BY 'GLANCE_DBPASS';

> GRANT ALL ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'GLANCE_DBPASS';

# su -s /bin/sh -c "glance-manage db_sync" glance

# keystone user-create --name=glance --pass=GLANCE_PASS --email=glance@example.com

# keystone user-role-add --user=glance --tenant=service --role=admin

# service glance-registry restart

# service glance-api restart

Step 3.      Adding and Verifying the Image Service Installation

# glance image-create --name="cirros-0.3.2-x86_64" --disk-format=qcow2 --container-format=bare --is-public=true --copy-from http://cdn.download.cirros-cloud.net/0.3.2/cirros-0.3.2-x86_64-disk.img

# glance image-list
