##5.2 Nova计算节点--openstack

##5.2 Nova计算节点
# compute 安装
#5.2.Nova-compute.sh

#基本配置：
#关闭selinux、防火墙
#更换阿里源、升级、重启、时间同步
#hostname设置
#安装OpenStack库

#安装配置Nova
yum install -y openstack-nova-compute
yum install -y python-openstackclient openstack-selinux

#设置Nova实例路径(磁盘镜像文件)
Vdir=/XLH_Data/nova
VHD=$Vdir/instances
mkdir -p $VHD
chown -R nova:nova $Vdir

#使用QEMU或KVM ,KVM硬件加速需要硬件支持
[[ `egrep -c ‘(vmx|svm)‘ /proc/cpuinfo` = 0 ]] && { Kvm=qemu; } || { Kvm=kvm; }
echo "使用 $Kvm"

# #nova配置
cp /etc/nova/nova.conf{,.bak}
#egrep -v ‘^$|#‘ /etc/nova/nova.conf
