利用rdo安装openstack

1、利用rdo安装openstack一、 系统网络规划：节点eth0（外网）eth1（内网）controller4343compute14444compute2442结构图：二、 安装1、 安装操作系统三个节点采用centos6.5，安装都采用minimal desktop方式，其中两个计算节点的安装不采用手动分区，而控制节点安装使用手动分区，主要是分出一个lvm分区。2、 系统配置（所有节点）（1）关闭防火墙和网络管理器，并使其永久关闭：# service iptables

2、stop#chkconfig iptables off#service networkmanager stop# chkconfig networkmanager off（2）关闭selinux：编辑/etc/sysconfig/selinux，如下：selinux=disabled（3）配置网络 依据网络规划配置网络，如下所示：# cat /etc/sysconfig/network-scripts/ifcfg-eth0device=eth0hwaddr=90:2b:34:33:94:d9type=ethernetipaddr=43netmask=255.255.25

4、f30-47a5-9742-bf59278c01bdonboot=yesnm_controlled=nobootproto=static 依据上述文件类型配置，最终达到任意外网可以相互ping通，且能上网，任意内网可以相互ping通！（4）、设置下载源 #cd /etc/yum.repos.d/# wget # yum makecache #更新yum源（5）、设置lvm（只在controller节点，如果没有进行手动分区的话，这步可忽略）（这个主要是提高虚拟机性能）# pvcreate /dev/sda5# vgcreate cinder-volumes /dev/sda5#sed -i /

5、cinder-volume/s/#/ /etc/fstab #去掉开机挂载3、安装openstack（1）、安装packstack（所有节点）# yum install -y /openstack/openstack-havana/rdo-release-havana.rpm# yum install -y openstack-packstack# yum -y update（2）packstack配置(只在controller节点) 创建应答文件# packstack -gen-answer-file=multi-node-gre-cont

6、roller.txt修改应答文件如下（网络采用gre模式）：config_nova_compute_hosts=43,42,44 config_neutron_ovs_tenant_network_type=gre config_neutron_ovs_tunnel_ranges=1:1000 config_neutron_ovs_tunnel_if=eth1（3）进行安装（只在controller节点）安装前确保所有网络畅通，三台机器都开启# packstack -answer-file=multi-node-gre-c

7、ontroller.txt（中间可能由于网络问题中断，可以重新运行上述命令）当出现installaton completed successfully，表示安装成功。 （4）配置网络（只在controller节点进行） 创建br-ex文件如下： # cat /etc/sysconfig/network-scripts/ifcfg-br-ex device=br-ex ipaddr=43 prefix=16 gateway=54 dns1=54 onboot=yes修改eth0如下（mac地址不能少）# cat /etc/s

8、ysconfig/network-scripts/ifcfg-eth0device=eth0onboot=yeshwaddr=90:2b:34:33:94:d9将eth0接口添加到br-ex网桥上，并重启网络：# ovs-vsctl add-port br-ex eth0; service network restart检查网络是否成功：#ovs-vsctl show #查看网桥信息198a4eec-a4d4-4bb1-8ba8-61a683e7424d bridge br-int port qvodc7814c2-e9 tag: 2 interface qvodc7814c2-e9 port
