||
====== Ubuntu系统安装及测试openflow的步骤： ======
|
||
|
||
一、获得源代码：
|
||
sudo apt-get install git-core automake m4 pkg-config libtool
|
||
git clone git://openflowswitch.org/openflow.git
|
||
cd openflow
|
||
[[./boot.sh]]
|
||
|
||
或者：
|
||
|
||
wget http://openflowswitch.org/downloads/openflow-1.0.0.tar.gz
|
||
tar xzf openflow-1.0.0.tar.gz
|
||
cd openflow-1.0.0
|
||
|
||
二、编译并安装user-space 交换机
|
||
|
||
./configure
|
||
make
|
||
sudo make install
|
||
|
||
注意：默认的安装位置是：/usr/local .
|
||
为了以后测试通过，需把下列文件复制到解压的目录中
|
||
cp [[/usr/local/bin/controller]] <OpenFlow ---Directory>/controller/
|
||
cp [[/usr/local/bin/ofprotocol]] <OpenFlow----Directory>/secchan/
|
||
cp [[/usr/local/bin/ofdatapath]] <OpenFlow----Directory>/udatapath/
|
||
cp [[/usr/local/bin/dpctl]] <OpenFlow----Directory>/utilities/
|
||
cp <OpenFlow----Directory>/regress/bin/{veth.map ,of_generic_eth.map}
|
||
|
||
三、安装Wireshark 协议分析软件
|
||
|
||
sudo apt-get install wireshark libgtk2.0-dev
|
||
cd utilities/wireshark_dissectors/openflow
|
||
make
|
||
sudo make install
|
||
|
||
四、测试套件设置(Regression Suite)
|
||
|
||
1、 首先安装测试套件依赖的软件
|
||
|
||
cd ~/<your openflow-dir>
|
||
sudo regress/scripts/install_deps.pl
|
||
sudo regress/scripts/install_perlmods_apt
|
||
|
||
2、卸载avahi-daemon，它会在测试时发送干扰数据包
|
||
|
||
sudo apt-get remove avahi-daemon
|
||
or
|
||
sudo apt-get install sysv-rc-conf
|
||
sudo sysv-rc-conf avahi-daemon off
|
||
|
||
3、禁用ipv6, 它会在测试时发送干扰数据包
|
||
|
||
% sudo vi /etc/sysctl.conf
|
||
|
||
net.ipv6.conf.all.disable_ipv6 = 1
|
||
net.ipv6.conf.default.disable_ipv6 = 1
|
||
|
||
% sudo vi /etc/modprobe.d/blacklist.conf
|
||
|
||
blacklist net-pf-10
|
||
blacklist ipv6
|
||
|
||
4、为了使上述 设置生效，需要重其电脑
|
||
|
||
% sudo shutdown -r now
|
||
|
||
五、执行测试
|
||
|
||
1、设置环境变量
|
||
|
||
cd ~/
|
||
cp <openflow-dir>/regress/scripts/env_vars .
|
||
vim env_vars
|
||
|
||
将其中的" OF_ROOT "设为 <openflow-dir>所在的路径
|
||
|
||
2、将env_vars中的环境变量导入到当前shell中
|
||
|
||
su
|
||
source [[~/env_vars]]
|
||
|
||
3、加载虚拟网络接口
|
||
|
||
veth_setup.pl
|
||
|
||
然后验证是否有veth{0,1...7}出现
|
||
|
||
/sbin/ifconfig | more
|
||
|
||
4、开启Wireshark网络流量分析软件
|
||
|
||
wireshark &
|
||
|
||
设置抓包的网络接口: Capture->Interfaces and select the lo (loopback) interface.
|
||
|
||
5、执行user-space交换机、控制器测试
|
||
|
||
of_user_veth_test.pl
|
||
|
||
|
||
6、当安装了openVswitch后，测试方法如下：
|
||
|
||
1、设置环境变量
|
||
|
||
vim env_vars
|
||
|
||
将其中的"OFT_OVS_ROOT "设为 openvswitch所在的路径
|
||
如：
|
||
|
||
export OFT_OVS_ROOT=/home/geekard/openvswitch-1.1.0pre2
|
||
|
||
2、将env_vars中的环境变量导入到当前shell中
|
||
|
||
su
|
||
source [[~/env_vars]]
|
||
|
||
3、加载虚拟网络接口
|
||
|
||
veth_setup.pl
|
||
|
||
然后验证是否有veth{0,1...7}出现
|
||
|
||
/sbin/ifconfig | more
|
||
|
||
4、开启Wireshark网络流量分析软件
|
||
|
||
wireshark &
|
||
|
||
设置抓包的网络接口: Capture->Interfaces and select the lo (loopback) interface.
|
||
|
||
5、测试kernel -space 交换机
|
||
|
||
of_ovs_veth_test.pl
|
||
|
||
可以通过如下命令查看，交换机内核模块[[/datapath/linux-2.6/openvswitch_mod.ko|openvswitch_mod.ko(位于 ~/openvswitch-1.1.0pre2]][[/datapath/linux-2.6/openvswitch_mod.ko]]
|
||
)是否被装载
|
||
|
||
lsmod |grep openvswitch
|
||
|
||
6、测试用户空间交换机
|
||
|
||
of_ovs_user_veth_test.pl
|
||
|
||
可以通过如下命令查看：
|
||
|
||
ps auxww
|
||
|
||
结果可能如下：
|
||
|
||
root 12866 1.0 0.5 11976 8040 pts/0 S+ 23:01 0:00 /usr/bin/perl -w /home/geekard/openflow/regress/bin/of_ovs_user_veth_test.pl
|
||
|
||
root 13189 0.0 0.0 4232 1524 pts/0 S+ 23:01 0:00 /home/geekard/openvswitch-1.1.0pre2/utilities/ovs-openflowd netdev@br0 --ports=veth1,veth3,veth5,veth7 tcp:127.0.0.1:6633 --listen=ptcp:6634 --fail=closed --inactivity-probe=999999
|
||
|
||
|
||
root 13199 16.0 0.5 11632 7712 pts/0 S+ 23:02 0:00 /usr/bin/perl -w /home/geekard/openflow/regress/projects/black_box/regress/test_packet_out/run.pl --map=/home/geekard/openflow/regress/bin/veth.map --controller=tcp:localhost:6633,tc
|
||
|
||
|
||
|
||
====== 单机测试： ======
|
||
|
||
1、切换到root账户
|
||
|
||
su
|
||
|
||
2、启动控制器
|
||
controller punix:/var/run/controller.sock &
|
||
|
||
3、启动user-space交换机
|
||
|
||
ofdatapath --no-slicing punix:/var/run/ofdata.sock -i eth0,eth1 &
|
||
|
||
注意：eth0,eth1 不能配有IP地址
|
||
dhcpcd -k eth* 去掉获得的ip地址
|
||
|
||
ofprotocol unix:/var/run/ofdata.sock unix:/var/run/controller.sock &
|
||
|
||
然后插在eth0,eth1口的设备就可以互相通信了。
