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

快乐的老鼠

1.实验环境
　　先参照笔者另一篇博文http://blog.iyunv.com/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
controller110.20.0.201172.16.0.201192.168.4.201nat
compute110.20.0.202172.16.0.201192.168.4.201nat
compute210.20.0.203172.16.0.201192.168.4.201nat　　下面给出compute1的网卡配置为例，另外的controller1和compute2可参考此配置

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

DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=10.20.0.202
NETMASK=255.255.255.0

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

DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=172.16.0.202
NETMASK=255.255.255.0

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

DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=192.168.4.202
NETMASK=255.255.255.0

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

DEVICE=eth3
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=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=10.20.0.201
CONFIG_COMPUTE_HOSTS=10.20.0.202,10.20.0.203
CONFIG_NETWORK_HOSTS=10.20.0.201
CONFIG_VCENTER_HOST=10.20.0.201
CONFIG_STORAGE_HOST=10.20.0.201
CONFIG_AMQP_HOST=10.20.0.201
CONFIG_MARIADB_HOST=10.20.0.201
CONFIG_KEYSTONE_ADMIN_PW=admin
CONFIG_KEYSTONE_DEMO_PW=demo
CONFIG_NOVA_COMPUTE_PRIVIF=eth2
CONFIG_NOVA_NETWORK_PUBIF=eth1
CONFIG_NOVA_NETWORK_PRIVIF=eth2
CONFIG_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
　　测试：

cat keystonerc_admin

vi /etc/nova/nova.conf

service openstack-nova-compute restart

service openstack-nova-scheduler restart

vi /etc/sysconfig/network-scripts/ifcfg-eth1

vi /etc/sysconfig/network-scripts/ifcfg-br-ex

vi /etc/neutron/plugin.ini

service network restart

service neutron-openvswitch-agent restart

service neutron-metadata-agent restart

service neutron-dhcp-agent restart

service neutron-l3-agent restart

ping 172.16.0.4

ssh 172.16.0.4 -l cirros

nova-manage vm list

. keystonerc_admin

nova-manage service list

neutron agent-list

service openstack-nova-compute stop

nova-manage service list

neutron agent-list
