Preliminary Mininet Installation/Configuration Notes
|
|
---
|
|
|
|
- This is not (yet) a 'release'; things may be broken.
|
|
|
|
- To install mininet, with root privileges:
|
|
|
|
python setup.py install
|
|
|
|
This places the mininet package in /usr/lib/python-2.5/site-packages/,
|
|
so that 'import mininet' will work.
|
|
|
|
- Installation is simplest with a distribution that includes a kernel
|
|
which supports the CLONE_NETNS unshare flag by default. Debian 5.0+ does
|
|
(e.g. current debian-testing release); Ubuntu doesn't. If your kernel
|
|
doesn't support it, you will need to build and install a kernel that
|
|
does! If you are using OpenVSwitch, 2.6.33 works best. For the reference
|
|
kernel switch, 2.6.30 is compatible.
|
|
|
|
- Mininet should probably be run either on a machine with
|
|
no other important processes, or on a virtual machine.
|
|
Multiple concurrent Mininet instances are not supported.
|
|
|
|
- To run the iperf test, you need to install iperf:
|
|
|
|
sudo aptitude/yum install iperf
|
|
|
|
We assume you already have ping installed. ;-)
|
|
|
|
- You may need other packages to run the examples, e.g.
|
|
|
|
sudo aptitude/yum install sshd xterm screen
|
|
|
|
Consult the appropriate example file for details.
|
|
|
|
- To switch to the most recent OpenFlow 0.8.9 release branch (the most
|
|
recent one with full NOX support):
|
|
|
|
git checkout -b release/0.8.9 remotes/origin/release/0.8.9
|
|
|
|
If you want to automatically load the kernel modules required
|
|
for OpenFlow, you could add something like the following to
|
|
/etc/rc.local:
|
|
|
|
insmod /home/openflow/openflow/datapath/linux-2.6/ofdatapath.ko
|
|
modprobe tun
|
|
|
|
- The reference OpenFlow controller (controller(8)) only supports 16
|
|
switches by default! If you wish to run a network with more than 16
|
|
switches, please recompile controller(8) with larger limits, or use a
|
|
different controller such as nox.
|
|
|
|
- For scalable configurations, you might need to increase some of your
|
|
kernel limits. Sample params are in sysctl_addon, which can be appended to
|
|
/etc/sysctl.conf (and modified as necessary for your desired
|
|
configuration):
|
|
|
|
sudo su -c "cat sysctl_addon >> /etc/sysctl.conf"
|
|
|
|
To save the config change, run:
|
|
|
|
sudo sysctl -p
|
|
