解释：我尽量把我能记录的步骤记录下来；
**************************************************************************************************
服务器：DELL R720
CPU:4
内存：64GB
硬盘：6TB (做RAID10) 可用空间 3TB
系统：Centos 6.4
用光盘安装Centos 6.4系统，这个大家都熟悉吧！到了分区的时候选择自定义分区：
| 分区名称 | 大小（MB） | | /boot | 1024 | | / | 102400 | | swap | 64000 | | 剩余空间 | --- |
网络配置：
有4块网卡我用了2块
eth0 外部网络地址，作用为了和openstack中创建的实例instance通信；关联浮动ip
eth1 管理ip地址192.168.1.199
*************************************************************************************************************************************
步骤一、安装好系统，在dell服务器中安装的centos6.4中网卡的名称成了em1、em2、em3、em4、现在我给他改成咱们熟悉的eth0、eth1、eth2、eth3
修改
# vi /etc/grub.conf
//找到这段，添加参数
title CentOS (2.6.32-358.el6.x86_64)
root (hd0,0)
kernel /vmlinuz-2.6.32-358.el6.x86_64 ro root=UUID=a13f3beb-1ff3-4295-93f8-2488add1de59 rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet biosdevname=0
initrd /initramfs-2.6.32-358.el6.x86_64.img
|
删除此文件
# rm -f /etc/udev/rules.d/70-persistent-cd.rules
更改网卡名称:
# cd /etc/sysconfig/network-scripts/
# mv ifcfg-em1 ifcfg-eth0
# mv ifcfg-em2 ifcfg-eth1
# mv ifcfg-em3 ifcfg-eth2
# mv ifcfg-em4 ifcfg-eth3
# perl -p -i -e 's/em1/eth0/g' ifcfg-eth0
# perl -p -i -e 's/em2/eth1/g' ifcfg-eth1
# perl -p -i -e 's/em3/eth2/g' ifcfg-eth2
# perl -p -i -e 's/em4/eth3/g' ifcfg-eth3
给dns文件+ i 节点不允许修改此文件中内容
# chattr +i /etc/resolv.conf
网络配置文件：
cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=00:24:E8:74:02:2C
TYPE=Ethernet
UUID=f49c5d7f-8c69-49aa-91d0-bb5448fe55c7
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=none
cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
HWADDR=00:24:E8:74:02:2E
TYPE=Ethernet
UUID=b38288a2-8641-4a50-8919-60cd2f60ed54
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.1.199
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.199 cloudhost2
重新启动
步骤二、把剩余硬盘空间划分成LVM
备注：因为剩下的空间大小已经超过了2T,所以fdisk命令就无能无力了，那么就需要使用parted命令来帮助我们了
# parted
GNU Parted 2.1
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) print
Model: DELL PERC 6/i (scsi)
Disk /dev/sda: 2999GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 1049kB 1075MB 1074MB ext4 boot
2 1075MB 108GB 107GB ext4
3 108GB 176GB 67.1GB linux-swap(v1)
(parted) mkpart
Partition name? []? cinder-volumes
File system type? [ext2]? ext4
Start? 176GB
End? 2999GB
Warning: WARNING: the kernel failed to re-read the partition table on /dev/sda (Device or
resource busy). As a result, it may not reflect all of your changes until after reboot.
(parted) quit
到这个地方又的重启一次，然后识别lvm分区；
步骤三、创建lvm
# pvcreate /dev/sda4
Physical volume "/dev/sda4" successfully created
# vgcreate cinder-volumes /dev/sda4 //cinder-volumes 这个名字必须是这个
Volume group "cinder-volumes" successfully created
# setenforce 0
# sed -i -e "s/SELINUX=enforcing/SELINUX=permissive/g" /etc/selinux/config
# yum -y install vim wget make gcc automake yum-utils unzip
开启网络转发功能
# vim /etc/sysctl.conf
net.ipv4.ip_forward = 1
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-arptables = 1
# sysctl -p
net.ipv4.ip_forward = 1
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key //这个报错不用管，等安装了openstack后就没了
error: "net.bridge.bridge-nf-call-iptables" is an unknown key
error: "net.bridge.bridge-nf-call-arptables" is an unknown key
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 4294967296
vim /etc/sysconfig/modules/openstack-quantum-linuxbridge.modules
#!/bin/sh
modprobe -b bridge >/dev/null 2>&1
exit 0
# chmod u+x /etc/sysconfig/modules/openstack-quantum-linuxbridge.modules
下载&安装openstack源
# yum install -y http://rdo.fedorapeople.org/openstack/openstack-grizzly/rdo-release-grizzly-3.noarch.rpm
下载并安装安装openstack的工具：packstack
# yum install -y openstack-packstack
修改这个文件中的参数是因为安装过程中会网络超时报错，所以我改了一下
#vim /usr/lib/python2.6/site-packages/packstack/puppet/modules/packstack/manifests/netns.pp
timeout => “3600”, 加一行
command => "yum update -y kernel iputils iproute"
安装openstack
# packstack --allinone //我的安装时间是时间13-14分钟

这个是在Centos6.4上安装G版本！看好多兄弟因为网络没搞定而苦恼，我还是把这个发布一下吧！希望能帮助你们把你们的问题解决掉！
另外提醒大家红帽的H版的也已经能用，我现在是在H版上测试！
packstack --allinone 安装H版的地址是:
http://openstack.redhat.com/Neutron-Quickstart
步骤：
sudo yum install -y http://rdo.fedorapeople.org/openstack-havana/rdo-release-havana.rpm yum -y update reboot
sudo yum install -y openstack-packstack python-netaddr
packstack --allinone
