OpenStack Mitaka部署<五; _OpenStack

蹉跎莫遣韶光老，人生唯有读书好。这篇文章主要讲述OpenStack Mitaka部署< 五; 相关的知识，希望能为你提供帮助。
本文介绍OpenvSwitch + vxlan部署，是在之前LinuxBridge + vxlan之上将LinuxBridge删除，替换为OVS
?
?共计两个节点，控制节点和计算节点
controller：
eth0:192.168.8.11管理
eth1:172.168.0.11隧道
eth2:没有IPnone外网
compute01：
eth0:192.168.8.31管理
eth1:172.168.0.31隧道
eth2:没有IPnone外网
其中，eth0放在同一个网络内，eth1放在同一个网络内，eth2放在同一个网络内

具体配置如下：
两个节点都执行：
# yum remove openstack-neutron-linuxbridge
# yum install openstack-neutron-openvswitch

控制节点：
[root@controller ~]# cat /etc/neutron/plugins/ml2/ml2_conf.ini
[DEFAULT]
[ml2]
type_drivers = flat,vxlan
tenant_network_types = vxlan
mechanism_drivers = openvswitch,l2population
extension_drivers = port_security
[ml2_type_geneve]
[ml2_type_gre]
[ml2_type_vlan]
[ml2_type_vxlan]
vni_ranges = 1001:2000
[securitygroup]
enable_ipset = True

br-ex是外部网络后面需要手工创建
[root@controller ~]# cat /etc/neutron/plugins/ml2/openvswitch_agent.ini
[DEFAULT]
[agent]
tunnel_types = vxlan
l2_population = True
[ovs]
bridge_mappings = external:br-ex
tunnel_bridge = br-tun
local_ip = 172.16.0.11
[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

[root@controller ~]# cat /etc/neutron/l3_agent.ini
[DEFAULT]
interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
【OpenStack Mitaka部署< 五; 】external_network_bridge = br-ex
[AGENT]

[root@controller ~]# cat /etc/neutron/dhcp_agent.ini
[DEFAULT]
interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = https://www.songbingjia.com/android/True
[AGENT]

计算节点：
[root@computer01 ~]# cat /etc/neutron/plugins/ml2/openvswitch_agent.ini
[DEFAULT]
[agent]
tunnel_types = vxlan
l2_population = True
[ovs]
bridge_mappings = external:br-ex
tunnel_bridge = br-tun
local_ip = 172.16.0.31
[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

neutron数据库我也删除了，按照文档重新创建了

# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

# su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \\
--config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron

服务：
控制节点：
systemctl enable neutron-server.service \\
neutron-openvswitch-agent.service neutron-dhcp-agent.service \\
neutron-metadata-agent.service
systemctl restart neutron-server.service \\
neutron-openvswitch-agent.service neutron-dhcp-agent.service \\
neutron-metadata-agent.service
计算节点：
systemctl enable neutron-openvswitch-agent.service
systemctl start neutron-openvswitch-agent.service

创建外网的br-ex
两个节点都执行（eth2上面不需要IP，只需要和外网交换机相连接即可，网卡配置文件方式为none就行）：
# ovs-vsctl add-br br-ex
# ovs-vsctl add-port br-ex eth2

用admin账号登陆密码ADMIN_PASS
管理员→网络创建网络创建一个vxlan网络tag是100
