    配置ML2和VXLAN

     

    1. 安装和配置Neutron ML2 框架

    (1) 安装在控制节点上(运行Neutron-server的节点)

    service neutron-server stop

    yum install openstack-neutron-ml2 python-pyudev -y

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

    (2) 配置ML2参数

    crudini --set /etc/neutron/neutron.conf DEFAULT core_plugin neutron.plugins.ml2.plugin.Ml2Plugin

    # 启用L3路由服务,这里还可以在后面增加LBaaS、VPNaaS、FWaaS插件,插件间用逗号分隔即可。

    crudini --set /etc/neutron/neutron.conf DEFAULT service_plugins neutron.services.l3_router.l3_router_plugin.L3RouterPlugin

    # 启动Mechanism插件,默认启用了OpenvSwitch,LinuxBridge和L2Population。

    crudini --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 mechanism_drivers openvswitch,linuxbridge,l2population

    # 启动Type插件,目前默认支持local、flat、vlan、gre、vxlan。

    crudini --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 type_drivers local,flat,vlan,gre,vxlan

    # 租户网络类型,这边我们选择vxlan

    crudini --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 tenant_network_types vxlan

    # 数据库配置,可直接参考/etc/neutron/neutron.conf

    crudini --set /etc/neutron/plugins/ml2/ml2_conf.ini database sql_connection mysql://neutron:<password>@<host>/neutron_ml2

    # 防火墙驱动

    crudini --set /etc/neutron/plugins/ml2/ml2_conf.ini securitygroup firewall_driver neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

    # 给每类Type插件,定义参数

    crudini --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2_type_vlan network_vlan_ranges <same range syntax as openvswitch>

    crudini --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2_type_flat flat_networks <list of physical_networks or *>

    crudini --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2_type_gre tunnel_id_ranges <list of ranges>

    # 这里我们为vxlan配置vni范围,在1:10000。

    crudini --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2_type_vxlan vni_ranges 1:10000

    (3) 数据库初始化

    mysql -e "drop database if exists neutron_ml2;"

    mysql -e "create database neutron_ml2 character set utf8;"

    mysql -e "grant all on neutron_ml2.* to 'neutron'@'%';"

    neutron-db-manage --config-file /usr/share/neutron/neutron-dist.conf --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugin.ini upgrade head

    service neutron-server start

    (4) 在网络节点和计算节点上配置

    /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini:

    [ovs]

    tunnel_id_ranges=1:10000
    tenant_network_type=vxlan
    enable_tunneling=True
    tunnel_type = vxlan
    local_ip = 192.168.188.136
     
    [agent]
     
    tunnel_types = vxlan

    l2_population = True

    service neutron-openvswitch-agent restart

    (5) 配置IPtables策略,开放vxlan端口

    /etc/sysconfig/iptables:

    -A INPUT -p udp --dport 4789 -j ACCEPT
