OpenVSwitch - Basic Install

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
