packstack + vxlan 利用vbox虚拟机搭建1控制节点+2计算节点openstack

1.实验环境

先参照笔者另一篇博文http://blog.csdn.net/u010366748/article/details/45366045（packstack allinone + vxlan 用vbox的虚拟机搭建openstack(单节点双网卡) ）的第一步配置好实验环境（3台机器都要配置好）

2.搭建openstack

（1）.启动虚拟机（当物理机用）后，为其配置网卡

节点 eth0（management network ） eth1（public/external    network ） eth2（private network） eth3 controller1 10.20.0.201 172.16.0.201 192.168.4.201 nat compute1 10.20.0.202 172.16.0.201 192.168.4.201 nat compute2 10.20.0.203 172.16.0.201 192.168.4.201 nat

下面给出compute1的网卡配置为例，另外的controller1和compute2可参考此配置

[root@compute1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0TYPE=EthernetONBOOT=yesNM_CONTROLLED=yesBOOTPROTO=staticIPADDR=10.20.0.202NETMASK=255.255.255.0

[root@compute1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1TYPE=EthernetONBOOT=yesNM_CONTROLLED=yesBOOTPROTO=staticIPADDR=172.16.0.202NETMASK=255.255.255.0

[root@compute1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth2

DEVICE=eth0TYPE=EthernetONBOOT=yesNM_CONTROLLED=yesBOOTPROTO=staticIPADDR=192.168.4.202NETMASK=255.255.255.0

[root@compute1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth3

DEVICE=eth3TYPE=EthernetONBOOT=yesNM_CONTROLLED=yesBOOTPROTO=dhcp

（2）.其他公共配置(all nodes)
修改hosts文件
vi /etc/hosts

      127.0.0.1 localhost
      ::1 localhost
      10.20.0.201 controller1
      10.20.0.202 compute1
      10.20.0.203 compute2
安装NTP 服务
      yum install ntp -y
      service ntpd start
      chkconfig ntpd on
修改NTP配置文件，配置从controller0时间同步。(除了controller0以外)
      vi /etc/ntp.conf
      server 10.20.0.201
      fudge 10.20.0.201 stratum 10 # LCL is unsynchronized

立即同步并检查时间同步配置是否正确。(除了controller0以外)
      ntpdate -u 10.20.0.201
      service ntpd restart
      ntpq -p
清空防火墙规则
      vi /etc/sysconfig/iptables
      *filter
      :INPUT ACCEPT [0:0]
      :FORWARD ACCEPT [0:0]
      :OUTPUT ACCEPT [0:0]
      COMMIT
重启防火墙，查看是否生效
      service iptables restart
      iptables -L
禁用 selinux
      vi /etc/selinux/config

    SELINUX=disabled

    reboot -h 0
（3）.安装
yum install -y https://repos.fedorapeople.org/repos/openstack/openstack-icehouse/rdo-release-icehouse-4.noarch.rpm
yetall openstack-packstack
产生应答文件：
packstack –gen-answer-file=myanswer.txt
vi myanswer.txt

CONFIG_CONTROLLER_HOST=10.20.0.201CONFIG_COMPUTE_HOSTS=10.20.0.202,10.20.0.203CONFIG_NETWORK_HOSTS=10.20.0.201CONFIG_VCENTER_HOST=10.20.0.201CONFIG_STORAGE_HOST=10.20.0.201CONFIG_AMQP_HOST=10.20.0.201CONFIG_MARIADB_HOST=10.20.0.201CONFIG_KEYSTONE_ADMIN_PW=adminCONFIG_KEYSTONE_DEMO_PW=demoCONFIG_NOVA_COMPUTE_PRIVIF=eth2CONFIG_NOVA_NETWORK_PUBIF=eth1CONFIG_NOVA_NETWORK_PRIVIF=eth2CONFIG_NOVA_NETWORK_FIXEDRANGE=CONFIG_NOVA_NETWORK_FLOATRANGE=CONFIG_MONGODB_HOST=10.20.0.201......其他仍为默认项

packstack –answer-file=myanswer.txt

这一过程比较漫长
