Local模式：一般測試時使用，只需一臺物理機即可。 GRE模式：隧道數量沒有限制，性能有點問題。 Vlan模式：vlan數量有4096的限制 VXlan模式：vlan數量沒有限制，性能比GRE好。 Flat模式：管理員創建租戶直接到外網，不需要NAT了。 目前的幾個項目正好用到了這種Flat模式的網絡結構，我覺得小項目中還是比較方便的，Openstack的體系和框架越來越穩定，項目中用用虛擬化和存儲，直接借助Openstack還是很方便。這時網絡結構可能就不需要用租戶、或者在細分其它，Flat模式反而更簡潔直觀，畢竟外網IP直接到了instance。 下面以我實驗環境配置為例，存儲部分配置省略。 環境：controller?node一臺???????compute?node一臺???????OS：Centos6.4 系統邏輯結構如下 一、controller?node?配置 1、網絡 [root@controller?~]#?more?/etc/hosts 192.168.3.98????controller 192.168.3.95????compute [root@controller?~]#?more?/etc/sysconfig/network-scripts/ifcfg-eth0???#外部網絡 DEVICE=eth0 HWADDR=10:BF:48:B7:8F:A0 TYPE=Ethernet ONBOOT=yes BOOTPROTO=none IPADDR=192.168.3.98 NETMASK=255.255.255.0 GATEWAY=192.168.3.1 [root@controller?~]#?more?/etc/sysconfig/network-scripts/ifcfg-eth1??#vm?及node之間通訊使用 DEVICE=eth1 TYPE=Ethernet ONBOOT=yes [root@controller?~]#??more?/etc/sysconfig/network NETWORKING=yes HOSTNAME=controller GATEWAY=192.168.3.1 [root@controller?~]#??more?/etc/resolv.conf? nameserver?202.102.134.68 nameserver?202.102.128.68 2、添加源 yum?install?wget cd?/etc/yum.repos.d/ wget? yum?list 3、LVM配置?[我單獨拿出一個分區給cinder使用，同時我的控制和計算節點也都是cinder節點] [root@controller?~]#?umount?/dev/sda5 [root@controller?~]#?pvcreate?/dev/sda5Physical?volume?"/dev/sda5"?successfully?created [root@controller?~]#?vgcreate?cinder-volumes?/dev/sda5Volume?group?"cinder-volumes"?successfully?created 4、安裝packstack yum?install?-y? yum?install?-y?openstack-packstack yum?-y?update 重啟機器 5、Packstack配置 創建一個應答文件 packstack?--gen-answer-file=multi-node.txt 修改應答文件，由于我已經有專門的cinder?volume,?所以不需要創建。如果沒有手工創建cinder?volume，那么這就不修改就可以。 CONFIG_CINDER_VOLUMES_CREATE=n??????????????#不在創建volume CONFIG_HEAT_INSTALL=y CONFIG_NAGIOS_INSTALL=y CONFIG_KEYSTONE_ADMIN_PW=admin CONFIG_NOVA_COMPUTE_HOSTS=192.168.3.98??#此處可以添加compute?node?IP?,號分割 CONFIG_NEUTRON_OVS_TENANT_NETWORK_TYPE=vlan CONFIG_NEUTRON_OVS_VLAN_RANGES=physnet1:100:200 CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-eth1 CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-eth1:eth1 CONFIG_HEAT_CLOUDWATCH_INSTALL=y CONFIG_HEAT_CFN_INSTALL=y CONFIG_NAGIOS_PW=admin 6、安裝?[RDO的方式部署簡直太簡單了，我值截取部分] [root@controller?~]#?packstack?--answer-file=multi-node.txt???????????#安裝過程，開始會輸入密碼，多節點的話會依此類推。安裝過程有可能因為源的原因中斷，可以重復運行。 Welcome?to?Installer?setup?utility Packstack?changed?given?value??to?required?value?/root/.ssh/id_rsa.pub Installing: Clean?Up...????????????????????????????????????????????[?DONE?] 7、?裝完后，有可能由于RDO的問題，沒有創建br-ex，需要我們手工來創建。 【目前看2014年后，redhat已經修復這個bug，剩下的只是我們對應的創建網卡配置文件和啟動port】 [root@controller?network-scripts]#?more?ifcfg-br-ex? DEVICE=br-ex IPADDR=192.168.3.98 PREFIX=24 GATEWAY=192.168.3.1 DNS1=202.102.134.68 ONBOOT=yes 修改?/etc/sysconfig/network-scripts/ifcfg-eth0,??注意：一定要加上eth0?的mac地址，不然會出錯。 [root@controller?network-scripts]#?more?ifcfg-eth0 DEVICE=eth0 HWADDR=00:90:27:E0:61:14 #TYPE=Ethernet ONBOOT=yes #BOOTPROTO=none #IPADDR=192.168.3.98 #NETMASK=255.255.255.0 ovs-vsctl?add-port?br-ex?eth0;?service?network?restart 當運行?ovs-vsctl?add-port的時候，網絡就會中斷，所以你兩條命令需要一起執行。 8、改變橋接網絡配置，此處主要修改neutron配置，我們的flat網絡模式是依賴在vlan的基礎上改進的，也是此文重點之處。 編輯 vi?/etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini? 原安裝完初始內容如下 [OVS] network_vlan_ranges=physnet1:100:200 tenant_network_type=vlan enable_tunneling=False integration_bridge=br-int bridge_mappings=physnet1:br-eth1 修改成 [OVS] network_vlan_ranges=physnet1,physnet2:100:200 tenant_network_type=vlan enable_tunneling=False integration_bridge=br-int bridge_mappings=physnet1:br-ex,physnet2:br-eth1 然后重啟相關服務，如果為省事，重啟機器 之后檢查網絡和橋接情況查詢 [root@controller?~]#?ovs-vsctl?show 9、創建Flat模式網絡，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?physnet1 Created?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=192.168.3.110 Created?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 查詢部署的服務是否正常 [root@controller?~(keystone_admin)]#?cinder-manage?service?list Binary???????????Host?????????????????????????????????Zone?????????????Status?????State?Updated?At cinder-volume????controller???????????????????????????nova?????????????enabled????????2014-02-10?07:42:22 cinder-scheduler?controller???????????????????????????nova?????????????enabled????????2014-02-10?07:42:30 [root@controller?~(keystone_admin)]#?cinder-manage?host?list host????????????????????????????zone???????????
