Centos 基于rdo多节点安装openstack

一、系统配置

1.修改网卡 emX为ethX

修改/etc/udev/rules.d/70-persistent-net.rules

# PCI device 0x14e4:0x163b (bnx2) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="d4:ae:53:c4:ff:22", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" 
# PCI device 0x14e4:0x163b (bnx2) (custom name provided by external tool) 
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="d4:ae:53:c4:ff:23", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" 

重命名网卡配置文件并修改设备名称

mv /etc/sysconfig/network-scripts/ifcfg-em1 /etc/sysconfig/network-scripts/ifcfg-eth0 

mv /etc/sysconfig/network-scripts/ifcfg-em2 /etc/sysconfig/network-scripts/ifcfg-eth1 

将其中的DEVICE=em1改为eth0，DEVICE=em2改为eth1

修改完之后重启机器。

2.配置IP

主机名   	角色	        NIC1	IP地址(外网)	NIC2	IP地址(内网)
controller	控制节点 	eth0	192.168.2.92	eht1	10.1.1.10
compute1	计算节点	eth0	192.168.2.93	eth1	10.1.1.11

3.安装packstack

yum install -y 

yum install openstack-packstack -y

二、packstack安装openstack

1.创建应答文件

packstack --gen-answer-file my_answers.txt

2.编辑

CONFIG_SWIFT_INSTALL=y
CONFIG_NOVA_COMPUTE_HOSTS=10.1.1.10,10.1.1.11
CONFIG_NEUTRON_OVS_TENANT_NETWORK_TYPE=gre
CONFIG_NEUTRON_OVS_TUNNEL_RANGES=1:1000
CONFIG_NEUTRON_OVS_TUNNEL_IF=eth1

3.开始安装

packstack --answer-file my_answers.txt

三、调整

1.设置br-ex

cat /etc/sysconfig/network-scripts/ifcfg-br-ex 
DEVICE=br-ex
IPADDR=192.168.2.92
PREFIX=16
GATEWAY=192.168.2.1
DNS1=114.114.114.114
ONBOOT=yes

cat /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
ONBOOT=yes
HWADDR=78:2b:cb:4c:de:64

2.升级dnsmasq

版本要求高于2.59。

rpm -Uvh
