OpenStack集群安装-11_nova计算节点安装

# Computer 计算服务
# 计算节点安装配置

计算节点安装

初始化环境

curl http://home.onlycloud.xin/code/openstack-01_init.sh | sh

安装OpenStack客户端,工具

yum install -y python-openstackclient openstack-selinux python2-PyMySQL openstack-utils

安装 Nova

yum install -y openstack-nova-compute

安装 Neutron

yum install -y openstack-neutron-linuxbridge ebtables ipset

计算节点配置

备份默认配置

[ -f /etc/nova/nova.conf.bak ] || cp /etc/nova/nova.conf{,.bak}
[ -f /etc/neutron/neutron.conf.bak ] || cp /etc/neutron/neutron.conf{,.bak}
[ -f /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak ] || cp /etc/neutron/plugins/ml2/linuxbridge_agent.ini{,.bak}

设置 Nova 实例路径(磁盘镜像文件)

Vdir=/date/nova
VHD=$Vdir/instances
mkdir -p $VHD
chown -R nova:nova $Vdir

虚拟化类型

使用QEMU或KVM ,KVM硬件加速需要硬件支持,虚拟机使用 qemu

#[[ `egrep -c '(vmx|svm)' /proc/cpuinfo` = 0 ]] && { Kvm=qemu; } || { Kvm=kvm; }
Kvm=qemu

nova 配置

获取第一块网卡名

Netname=$(ip add|egrep global|awk '{ print $NF }'|head -n 1)

---

获取第一块网卡 ip地址

MyIP=$(ip add|grep global|awk -F'[ /]+' '{ print $3 }'|head -n 1)

---

VNC代理地址vip

VncProxy=10.0.0.10

---

服务管理

配置服务跟随系统启动, 启动服务

systemctl enable libvirtd openstack-nova-compute neutron-linuxbridge-agent
systemctl start libvirtd openstack-nova-compute neutron-linuxbridge-agent

使用脚本

site='http://home.onlycloud.xin'
curl $site/code/openstack-11_nova.sh -o openstack-nova.sh
sh openstack-nova.sh
