X86单网卡Desktop源码安装Openstack 组件之Keystone、Glance、Nova

由于我的试验环境有限， 所以在本地的x86的电脑上单节点安装Openstack的基础组件， 而没有使用多Compute节点的方式来部署， 据说那也是挺挑战的， 等有闲置的机器我会去尝试一下。

电脑配置如下：
OS： Fedora 17
CPU: Intel(R) Core(TM) i3 CPU M 370 @ 2.40GHz
Memory: 4G

安装步骤如下：

1、到Github中下载各个组件的源码

Keystone >> https://github.com/openstack/keystone.git
keystoneClient >> https://github.com/openstack/python-keystoneclient.git
Nova >> https://github.com/openstack/nova.git
NovaClient >> https://github.com/openstack/python-novaclient.git
Glance >> https://github.com/openstack/glance.git
GlanceClient >> https://github.com/openstack/python-glanceclient.git

下载想要的版本，解压
  以下假定都解压到/opt/openstack/ 下

2、安装Mysql、RabbitMq-Server（可选）或Qpid ，用于组件内的通信
mysql、rabbiqmq 均是通过yum安装的，也可以源码安装。

配置Rabbitmq
将以下两行添加至/etc/rabbitmq/rabbitmq.conf 以及/etc/rabbitmq/rabbitmq-env.conf
DENAME=rabbit@localhost
NODE_IP_ADDRESS=127.0.0.1

为rabbitmq设置guest的密码 
    rabbitmqctl change_password guest flopsymopsy
mysql设置root密码
    mysqladmin -u root password 'nomoresecret' 
    mysql -u root -pnomoresecret
        create database keystone;
        create database glance;
        create database nova;


添加网卡br100

vim /etc/networks
添加以下至/etc/networks中
auto br100
iface br100 inet static
address 10.0.0.0
netmask 255.255.255.0
gateway 10.0.0.1
bridge_ports wlan0
bridge_stp off
bridge_fd 0
增加一个桥接设备， 我们将它命名为br100
brctl addbr br100
/etc/init.d/networking restart

3、编译安装个组件
cd ~/nova
 pip install -r tools/pip-requires
 python setup.py install
cd ~keystone 
 pip install -r tools/pip-requires
 python setup.py install
cd ~/glance
 pip install -r tools/pip-requires
 python setup.py install

如何安装正常的情况下，在每个组件下面有etc目录
将每个组件etc目录下的文件拷贝至/etc目录下
 cd keystone/
 cp -R etc/* /etc/
 cd glance/
 cp -R etc/* /etc/
 cd nova/
 cp -R etc/* /etc/

4、配置keystone
vim /etc/keystone/keystone.conf
设置admin的Token
[DEFAULT]
admin_token = 721457575107e4d57fe3
也可代码修改token的值 方法如下
    export ADMIN_TOKEN=$(openssl rand -hex 10)
    openstack-config --set /etc/keystone/keystone.conf DEFAULT \ 
    admin_token $ADMIN_TOKEN
修改mysql链接，修改为之前设置的用户名密码
[sql]
connection = mysql://root:nomoresecret@localhost/keystone?charset=utf8

启动keystone服务
    keystone-all --config-dir=/etc/keystone &

数据库中创建相应的数据表
    keystone-manage db_sync

5、配置glance

vim /etc/glance-api.conf
sql_connection = mysql://root:nomoresecret@localhost/glance?charset=utf8

vim /etc/glance/glance-api-paste.ini
[filter:authtoken]
paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
delay_auth_decision = true
admin_tenant_name = service
admin_user = glance
admin_password = supersecret

vim /etc/glance-registry.conf
[keystone_authtoken]
signing_dir = /var/cache/glance/registry
auth_uri = http://127.0.0.1:5000/
auth_host = 127.0.0.1
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = glance
admin_password = supersecret

[paste_deploy]
flavor = keystone

创建glance数据表
    glance-manage db_sync

6、配置nova

vim /etc/nova/nova.conf

[DEFAULT]
verbose=True
auth_strategy=keystone
allow_resize_to_same_host=True
api_paste_config=/etc/nova/api-paste.ini
rootwrap_config=/etc/nova/rootwrap.conf

auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = nova
admin_password = supersecret
signing_dir = /tmp/keystone-signing-nova

至此，openstack的三个基础单节点搭建成功，启动服务流程见这
然后剩下的就是启动各个服务，创建初始化数据，进行相关的操作了

安装中主要参考了以下文章
