Openstack Folsom - Installation of Nova

Before Installation

Add repository

root@nova:~$ apt-get install -y python-software-properties
root@nova:~$ add-apt-repository ppa:openstack-ubuntu-testing/folsom-trunk-testing
root@nova:~$ add-apt-repository ppa:openstack-ubuntu-testing/folsom-deps-staging
root@nova:~$ apt-get update && apt-get -y dist-upgrade

Hostname Setting

最簡單的方式是在 /etc/hosts 內設定會用到的 hostname
172.17.123.12   rabbitmq
172.17.123.12   mysql
172.17.123.12   cinder
172.17.123.13   keystone
172.17.123.14   swift-proxy
172.17.123.16   glance
172.17.123.17   nova

MySQL Setting

在 MySQL 內加入一個新的 database, 如果 MySQL 和 Glance 在同一台 Server 上, 記得也要設定從 localhost 登入的權限及密碼
mysql> CREATE DATABASE nova;
Query OK, 1 row affected (0.00 sec)

mysql> GRANT ALL ON nova.* TO 'nova'@'%' IDENTIFIED BY 'password';
Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'password';
Query OK, 0 rows affected (0.00 sec)

在 Nova 這邊記得也要裝 mysql-client, 然後可以測試看看能不能連線成功
root@nova:~$ apt-get install mysql-client python-mysqldb
root@nova:~$ mysql -h 172.17.123.12 -u nova -ppassword
Welcome to the MySQL monitor.  Commands end with ; or \g.

mysql>

Environment Variable Setting

編輯一個設定檔: novarc, 設定一些等下會用到的區域變數, 並且匯到 .bashrc 之中, 下次再進來就不需要重新設定
root@glance:~$ cat novarc
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=password
export OS_AUTH_URL="http://keystone:5000/v2.0/"
export SERVICE_ENDPOINT="http://keystone:35357/v2.0"
export SERVICE_TOKEN=password
root@glance:~$ source novarc
root@glance:~$ echo "source novarc">>.bashrc

Keystone Setting

把 endpoint 的網址設定好
root@nova:~$ apt-get install python-keystoneclient
root@nova:~$ keystone endpoint-list

Nova Package

因為是要和 Cinder 整合, 所以沒有安裝 nova-volume

/etc/nova/nova.conf

內容是設定成和 Keystone, Cinder(Ceph), Glance(Ceph), 整合在一起, 中間其實用不到 iscsi server.

/etc/nova/api.paste.ini

要設定 keystone 的相關資訊
...
[filter:authtoken]
paste.filter_factory = keystone.middleware.auth_token:filter_factory
auth_host = keystone
auth_port = 35357
auth_protocol = http
#admin_tenant_name = %SERVICE_TENANT_NAME%
#admin_user = %SERVICE_USER%
#admin_password = %SERVICE_PASSWORD%
admin_tenant_name = service
admin_user = nova
admin_password = password
signing_dirname = /tmp/keystone-signing-nova

/etc/nova/nova_restart.sh

另外準備一個 nova_restart.sh, 方便等下使用
#!/bin/bash
for a in nova-network nova-compute nova-api nova-scheduler; do sudo service $a stop; done
for a in nova-consoleauth nova-cert novnc libvirt-bin; do sudo service $a stop; done
for a in nova-network nova-compute nova-api nova-scheduler; do sudo service $a start; done
for a in nova-consoleauth nova-cert novnc libvirt-bin; do sudo service $a start; done

啟動 nova 之後, 要記得成生成 database, 完成後就可以把服務啟動
root@nova:~$ chown -R nova:nova *
root@nova:~$ nova-manage db sync
root@nova:~$ /etc/nova/nova_restart.sh
root@nova:~$ nova-manage service list

驗証一下和所有的 component 是否正確連結, 首先驗証一下 Cinder

再來驗証一下和 Glance 的連結是否正確

看起來是成功了, 再多看一下這個 VM 的 xml 設定, 透過以下這個指令 virsh dumpxml instance-00000006 可以看到他新增了一個 disk, 是透過 rbd protocol
...

Create Ubuntu(Precise) Virtual Machine

Ubuntu 的 image 可以到這邊下載
http://uec-images.ubuntu.com/precise/current/
裡面分成兩種, 一種是把 kernel image & machine image 分開的, 另一種則是用 qcow2 包起來

拆開的: precise-server-cloudimg-amd64-root.tar.gz
包起來的: precise-server-cloudimg-amd64-disk1.img
Openstack Folsom - Installation of Glance with Ceph 內有紀錄怎麼第二種的上傳方式, 至於第一種就要解壓縮後, 分別上傳 aki & ami, 然後連結起來. 這邊假設已經上傳好了

註1:

在執行 nova 指令時, 會不斷的叫你輸入 keyring 的 password, 目前也有人把他提報成一個 bug.
https://bugs.launchpad.net/python-novaclient/+bug/1020238
http://wiki.openstack.org/KeyringSupport
如果不想要一直輸入 password, 可以在 .bashrc 內加上一行
alias nova='nova --no-cache'

註2:

在裝完 horizon 之後, 發現 vnc 起不來, 才發現 vncproxy 啟動失敗
在 /var/log/upstart/nova-novncproxy.log 內
Traceback (most recent call last):
  File "/usr/bin/nova-novncproxy", line 29, in 
    import websockify
在網路上找了一下發現是 known issue, 只需要去下載最新的 package, 就會解掉這個問題
https://bugs.launchpad.net/ubuntu/+source/websockify/+bug/1060374

root@nova:~$ wget https://launchpad.net/ubuntu/+archive/primary/+files/websockify_0.2~20121002-0ubuntu1_amd64.deb
root@nova:~$ dpkg -i websockify_0.2~20121002-0ubuntu1_amd64.deb
root@nova:~$ ./nova_restart.sh

您好可否請教您是否有試過floating IP也就是外部的IP是抓取區網的DHCP server分配的IP而不是nova自己分配的IP? 謝謝~~

有試過類似的, 但遇過 DHCP server 發了 ip, 但 VM 卻收不到的狀況, 後來沒有再追這個問題, 因為都從 nova 內部設定 DHCP server. 你可以試試去 forum 問問看.
