《OpenStack系统架构设计实战》7.5.2 简化安装

关灯直达底部

Ironic简化安装通常适用于开发者搭建开发原型环境,可以不依赖于OpenStack的其他组件,将Ironic的内部组件运转起来。以Ubuntu系统为例,环境为Python2.7。

1)安装Ironic依赖包。

sudo apt-get install python-dev libssl-dev python-pip libmysqlclient- dev libxml1-dev libxslt-dev libpq-dev git git-review libffi-dev gettext ipmitool psmisc graphviz

2)安装virtualenv环境。

sudo easy_install nosesudo pip install virtualenv setuptools-git flake8 tox testrepository

3)安装rabbit-mq和mysql。

# install rabbit message broker# Ubuntu/Debian:sudo apt-get install rabbitmq-server# optionally, install mysql-server# Ubuntu/Debian:# sudo apt-get install mysql-server

4)从git下载Ironic代码库,并使用virtualenv安装。

# activate the virtualenvcd ~git clone https://git.openstack.org/openstack/ironiccd ironictox -evenv --notestsource .tox/venv/bin/activate# install ironic within the virtualenvpython setup.py develop

5)配置Ironic配置文件。

# copy sample config and modify it as necessarycp etc/ironic/ironic.conf.sample etc/ironic/ironic.conf.local# disable auth since we are not running keystone heresed -i "s/#auth_strategy=keystone/auth_strategy=noauth/" etc/ironic/ironic.conf.local# Use the 'fake_ipmitool' test driversed -i "s/#enabled_drivers=pxe_ipmitool/enabled_drivers=fake_ipmitool/" etc/ironic/ironic.conf.local# set a fake host name [useful if you want to test multiple services on the same host]sed -i "s/#host=.*/host=test-host/" etc/ironic/ironic.conf.local# turn off the periodic sync_power_state task, to avoid getting NodeLocked exceptionssed -i "s/#sync_power_state_interval=60/sync_power_state_interval=-1/" etc/ironic/ironic.conf.local

6)初始化Ironic数据库,根据实际情况配置数据库连接。

mysql -u root -e “create schema ironic”sed -i “s/#connection=.*/connection=mysql://[email protected]/ironic/” etc/ironic/ironic.conf.localironic-dbsync --config-file etc/ironic/ironic.conf.local create_schema

7)debug模式启动ironic-api。

# start the API serviceironic-api -v -d --config-file etc/ironic/ironic.conf.local

8)debug模式启动Ironic-conductor。

ironic-conductor -v -d --config-file etc/ironic/ironic.conf.local

9)安装ironic-pythonclient。

# from your home or source directorycd ~git clone https://git.openstack.org/openstack/python-ironicclientcd python-ironicclienttox -evenv --notestsource .tox/venv/bin/activateexport OS_AUTH_TOKEN=fake-tokenexport IRONIC_URL=http://localhost:6385/

现在可以使用ironic命令与ironic-api交互了,也可以测试Ironic接口了。

# get a list of available commandsironic help# get the list of drivers currently supported by the available conductor(s)ironic driver-list# get a list of nodes (should be empty at this point)ironic node-list

也可以注册一个伪节点。
