OpenStack安装手册 - 计算节点安装，包括PYTHON-NOVACLIENT库安装，GLANCE镜像存储服务安装。
4 计算节点安装
4.1 前提工作
· 导入第三方软件源
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
rpm -Uvh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
· 安装依赖包
yum -y install swig libvirt-python libvirt qemu-kvm gcc make gcc-c++ patch m4 python-devel libxml2-devel libxslt-devel libgsasl-devel openldap-devel sqlite-devel openssl-devel wget telnet gpxe-bootimgs gpxe-roms gpxe-roms-qemu dmidecode git scsi-target-utils kpartx socat vconfig aoetools python-pip
rpm -Uvh http://veillard.com/libvirt/6.3/x86_64/dnsmasq-utils-2.48-6.el6.x86_64.rpm
ln -sv /usr/bin/pip-python /usr/bin/pip
4.2 NTP时钟同步配置
· 安装NTP相关命令包
yum -y install ntpdate
· 跟控制节点同步时间并写入硬件
ntpdate 192.168.1.2
hwclock -w
· 将时间同步添加到计划任务
echo '30 8 * * * root /usr/sbin/ntpdate 192.168.1.2;hwclock -w' >>/etc/crontab
4.3 PYTHON-NOVACLIENT库安装
· 下载源码包
wget https://launchpad.net/nova/essex/2012.1/+download/python-novaclient-2012.1.tar.gz -P /opt
· 安装依赖包
yum -y install python-simplejson python-prettytable python-argparse python-nose1.1 python-httplib2 python-virtualenv MySQL-python
· 解压并安装PYTHON-NOVACLIENT库
cd /opt
tar xf python-novaclient-2012.1.tar.gz
cd python-novaclient-2012.1
python setup.py install
rm -f ../python-novaclient-2012.1.tar.gz
4.4 GLANCE镜像存储服务安装
· 下载源码包
wget https://launchpad.net/glance/essex/2012.1/+download/glance-2012.1.tar.gz -P /opt
· 安装依赖包
yum install -y python-anyjson python-kombu
pip install xattr==0.6.0 iso8601==0.1.4 pysendfile==2.0.0 pycrypto==2.3 wsgiref boto==2.1.1
· 解压并安装GLANCE镜像存储服务
cd /opt
tar xf glance-2012.1.tar.gz
cd glance-2012.1
python setup.py install
rm -f ../glance-2012.1.tar.gz
