Environment
- System: Ubuntu 12.04 TLS
- OpenVSwtich : v.20 openvswitch
- Controller: Floodlight controller
#Install#
OpenVSwitch
按照文件中的INSTALL 即可安裝完成,
- ./configure (如果要安裝kernel module的話,
./configure --with-linux=/lib/modules/
uname -r/build
來建置) - make
- make modules_install
- /sbin/modprobe openvswitch
- 用
lsmod | grep openvswitch
檢查kernel module 是否載入 - mkdir -p /usr/local/etc/openvswitch
- ovsdb-tool create /usr/local/etc/openvswitch/conf.db vswitchd/vswitch.ovsschema (創造ovs-db)
ovsdb-server –remote=punix:/usr/local/var/run/openvswitch/db.sock \
--remote=db:Open_vSwitch,Open_vSwitch,manager_options \ --private-key=db:Open_vSwitch,SSL,private_key \ --certificate=db:Open_vSwitch,SSL,certificate \ --bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert \ --pidfile --detach
ovs-vsctl –no-wait init
- ovs-vswitchd –pidfile –detach
Network Environment
- 主機板網路孔*1 + 4 port 網卡
- eth0 藉由internet與controller連接 (out-bound)
- 用ovs 創造一個虛擬的interface br0,把eth1, eth2, eth3, eth4加入 (in-bound)
- eth1 & eth4 分別連上兩台host
- host1: 192.168.122.100
- host2: 192.168.122.101
Operation
- ovs-vsctl add-br br0
- ovs-vsctl add-port br0 eth1
- ovs-vsctl add-port br0 eth2
- ovs-vsctl add-port br0 eth3
- ovs-vsctl add-port br0 eth4
- ovs-vsctl set-controller br0 tcp:x.x.x.x:6633
Controller side
- Switch 00:00:90:e2:ba:49:58:84 connected.
- Watch x.x.x.x:8080/ui/index.html to see switch
Ovs side
- ovs-vsctl show
