openstack havana vlan如何安装

小编给大家分享一下openstack havana vlan如何安装，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

Local模式：一般测试时使用，只需一台物理机即可。GRE模式：隧道数量没有限制，性能有点问题。Vlan模式：vlan数量有4096的限制VXlan模式：vlan数量没有限制，性能比GRE好。Flat模式：管理员创建租户直接到外网，不需要NAT了。目前的几个项目正好用到了这种Flat模式的网络结构，我觉得小项目中还是比较方便的，Openstack的体系和框架越来越稳定，项目中用用虚拟化和存储，直接借助Openstack还是很方便。这时网络结构可能就不需要用租户、或者在细分其它，Flat模式反而更简洁直观，毕竟外网IP直接到了instance。下面以我实验环境配置为例，存储部分配置省略。环境：controller node一台       compute node一台       OS：Centos6.4系统逻辑结构如下

一、controller node 配置1、网络[root@controller ~]# more /etc/hosts192.168.3.98    controller192.168.3.95    compute[root@controller ~]# more /etc/sysconfig/network-scripts/ifcfg-eth0   #外部网络DEVICE=eth0HWADDR=10:BF:48:B7:8F:A0TYPE=EthernetONBOOT=yesBOOTPROTO=noneIPADDR=192.168.3.98NETMASK=255.255.255.0GATEWAY=192.168.3.1[root@controller ~]# more /etc/sysconfig/network-scripts/ifcfg-eth2  #vm 及node之间通讯使用DEVICE=eth2TYPE=EthernetONBOOT=yes[root@controller ~]#  more /etc/sysconfig/networkNETWORKING=yesHOSTNAME=controllerGATEWAY=192.168.3.1[root@controller ~]#  more /etc/resolv.conf nameserver 202.102.134.68nameserver 202.102.128.68

2、添加源yum install wgetcd /etc/yum.repos.d/wget yum list

3、LVM配置 [我单独拿出一个分区给cinder使用，同时我的控制和计算节点也都是cinder节点][root@controller ~]# umount /dev/sda5[root@controller ~]# pvcreate /dev/sda5  Physical volume "/dev/sda5" successfully created[root@controller ~]# vgcreate cinder-volumes /dev/sda5  Volume group "cinder-volumes" successfully created

4、安装packstackyum install -y yum install -y openstack-packstackyum -y update重启机器

5、Packstack配置创建一个应答文件

packstack --gen-answer-file=multi-node.txt

修改应答文件，由于我已经有专门的cinder volume, 所以不需要创建。如果没有手工创建cinder volume，那么这就不修改就可以。

CONFIG_CINDER_VOLUMES_CREATE=n              #不在创建volumeCONFIG_HEAT_INSTALL=yCONFIG_NAGIOS_INSTALL=yCONFIG_KEYSTONE_ADMIN_PW=adminCONFIG_NOVA_COMPUTE_HOSTS=192.168.3.98  #此处可以添加compute node IP ,号分割CONFIG_NEUTRON_OVS_TENANT_NETWORK_TYPE=vlanCONFIG_NEUTRON_OVS_VLAN_RANGES=physnet1:100:200CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-eth2CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-eth2:eth2CONFIG_HEAT_CLOUDWATCH_INSTALL=yCONFIG_HEAT_CFN_INSTALL=yCONFIG_NAGIOS_PW=admin

6、安装 [RDO的方式部署简直太简单了，我值截取部分][root@controller ~]# packstack --answer-file=multi-node.txt           #安装过程，开始会输入密码，多节点的话会依此类推。安装过程有可能因为源的原因中断，可以重复运行。Welcome to Installer setup utilityPackstack changed given value  to required value /root/.ssh/id_rsa.pub

Installing:Clean Up...                                            [ DONE ]

7、 装完后，有可能由于RDO的问题，没有创建br-ex，需要我们手工来创建。【目前看2014年后，redhat已经修复这个bug，剩下的只是我们对应的创建网卡配置文件和启动port】[root@controller network-scripts]# more ifcfg-br-ex DEVICE=br-exIPADDR=192.168.3.98PREFIX=24GATEWAY=192.168.3.1DNS1=202.102.134.68ONBOOT=yes修改 /etc/sysconfig/network-scripts/ifcfg-eth0,  注意：一定要加上eth0 的mac地址，不然会出错。

[root@controller network-scripts]# more ifcfg-eth0DEVICE=eth0HWADDR=00:90:27:E0:61:14#TYPE=EthernetONBOOT=yes#BOOTPROTO=none#IPADDR=192.168.3.98#NETMASK=255.255.255.0

ovs-vsctl add-port br-ex eth0; service network restart当运行 ovs-vsctl add-port的时候，网络就会中断，所以你两条命令需要一起执行。

8、改变桥接网络配置，此处主要修改neutron配置，我们的flat网络模式是依赖在vlan的基础上改进的，也是此文重点之处。编辑vi /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini 原安装完初始内容如下[OVS]network_vlan_ranges=physnet1:100:200tenant_network_type=vlanenable_tunneling=Falseintegration_bridge=br-intbridge_mappings=physnet1:br-eth2

修改成

[OVS]network_vlan_ranges=physnet1,physnet2:100:200tenant_network_type=vlanenable_tunneling=Falseintegration_bridge=br-intbridge_mappings=physnet1:br-ex,physnet2:br-eth2

然后重启相关服务，如果为省事，重启机器之后检查网络和桥接情况查询[root@controller ~]# ovs-vsctl show

9、创建Flat模式网络，目前都可以在web界面操作[root@controller ~(keystone_admin)]# neutron net-create Public --provider:network_type flat --provider:physical_network physnet1Created a new network:+---------------------------+--------------------------------------+| Field                     | Value                                |+---------------------------+--------------------------------------+| admin_state_up            | True                                 || id                        | 3c5eca6f-aeb4-451b-9fa2-ed70d8bab9e9 || name                      | Public                               || provider:network_type     | flat                                 || provider:physical_network | physnet1                             || provider:segmentation_id  |                                      || shared                    | False                                || status                    | ACTIVE                               || subnets                   |                                      || tenant_id                 | 2cfb66b8a9524cc68c2e1bf424bda943     |+---------------------------+--------------------------------------+[root@controller ~(keystone_admin)]# neutron subnet-create Public 192.168.3.0/24 --disable-dhcp --allocation-pool start=192.168.3.100,end=192.168.3.110Created a new subnet:+------------------+----------------------------------------------------+| Field            | Value                                              |+------------------+----------------------------------------------------+| allocation_pools | {"start": "192.168.3.100", "end": "192.168.3.110"} || cidr             | 192.168.3.0/24                                     || dns_nameservers  |                                                    || enable_dhcp      | False                                              || gateway_ip       | 192.168.3.1                                        || host_routes      |                                                    || id               | 8d089754-3764-4249-98f2-402f62a872bc               || ip_version       | 4                                                  || name             |                                                    || network_id       | 3c5eca6f-aeb4-451b-9fa2-ed70d8bab9e9               || tenant_id        | 2cfb66b8a9524cc68c2e1bf424bda943                   |+------------------+----------------------------------------------------+

10、cinder配置查询部署的服务是否正常[root@controller ~(keystone_admin)]# cinder-manage service listBinary           Host                                 Zone             Status     State Updated Atcinder-volume    controller                           nova             enabled        2014-02-10 07:42:22cinder-scheduler controller                           nova             enabled        2014-02-10 07:42:30[root@controller ~(keystone_admin)]# cinder-manage host listhost                            zone           controller                      nova

然后查询论证是否成功[root@controller ~(keystone_admin)]# lvdisplay   --- Logical volume ---  LV Path                /dev/cinder-volumes/volume-0a9cc8fc-d3fd-4dd1-9501-9c3813056415  LV Name                volume-0a9cc8fc-d3fd-4dd1-9501-9c3813056415  VG Name                cinder-volumes  LV UUID                zbGuJa-3bdk-V6UZ-ZBsx-FWeA-dlys-qMphas  LV Write Access        read/write  LV Creation host, time controller, 2014-02-10 15:46:44 +0800  LV Status              available  # open                 1  LV Size                5.00 GiB  Current LE             1280  Segments               1  Allocation             inherit  Read ahead sectors     auto  - currently set to     4096  Block device           253:0

[root@controller ~(keystone_admin)]# cinder list+--------------------------------------+-----------+--------------+------+-------------+----------+-------------+|                  ID                  |   Status  | Display Name | Size | Volume Type | Bootable | Attached to |+--------------------------------------+-----------+--------------+------+-------------+----------+-------------+| 0a9cc8fc-d3fd-4dd1-9501-9c3813056415 | available |     oak      |  5   |     SSD     |  false   |             |+--------------------------------------+-----------+--------------+------+-------------+----------+-------------+[root@controller ~(keystone_admin)]#

此时，启动一个instance可以在云硬盘中，选择挂载，挂载到相应的instance上。

二、compute node 配置1、网络，参考控制节点，其次检查ntp，时间是否与控制节点同步2、添加源和Openstack软件环境都参考控制节点的前期准备3、RDO应答文件，填写了compute node IP后，一般nova-compute、openstack-neutron-openvswitch和MySQL-python都已经安装4、因为我的环境是Flat模式，所以此处neutron配置文件还需修改，然后创建相应的桥修改neutronvi /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini [OVS]network_vlan_ranges=physnet1,physnet2:100:200tenant_network_type=vlanenable_tunneling=Falseintegration_bridge=br-intbridge_mappings=physnet1:br-ex,physnet2:br-eth2

创建桥[root@compute neutron]# cd /etc/sysconfig/network-scripts/[root@compute network-scripts]# more ifcfg-br-ex DEVICE=br-exIPADDR=192.168.3.95PREFIX=24GATEWAY=192.168.3.1DNS1=202.102.134.68ONBOOT=yes[root@compute network-scripts]# more ifcfg-eth0DEVICE=eth0HWADDR=00:90:27:E0:61:14#TYPE=EthernetONBOOT=yes#BOOTPROTO=none#IPADDR=192.168.3.95#NETMASK=255.255.255.0#GATEWAY=192.168.3.1[root@compute network-scripts]# ovs-vsctl add-br br-ex[root@compute network-scripts]# ovs-vsctl add-port br-ex eth0; service network restart

[root@compute network-scripts]# ovs-vsctl show3875869a-c249-4514-aadc-b95b92e7f304    Bridge br-ex        Port br-ex            Interface br-ex                type: internal        Port "eth0"            Interface "eth0"    Bridge br-int        Port br-int            Interface br-int                type: internal    ovs_version: "1.11.0"

5、cinder 配置[root@compute ~]# umount /dev/sda4[root@compute ~]# pvcreate /dev/sda4  Physical volume "/dev/sda4" successfully created[root@compute ~]# vgcreate cinder-volumes /dev/sda4  Volume group "cinder-volumes" successfully created

yum install openstack-cinder openstack-utils

vi  /etc/cinder/api-paste.ini 参考拷贝控制节点内容[filter:authtoken]paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory# signing_dir is configurable, but the default behavior of the authtoken# middleware should be sufficient.
