#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
