Mininet Installation/Configuration Notes |

Mininet 2.0.0 |

|
8 |
The supported installation methods for Mininet are 1) using |
9 |
a pre-built VM image, and 2) native installation on Ubuntu. You |
10 |
can also easily create your own Mininet VM image (3). |
11 |
|
12 |
(Other distributions may be supported in the future - if you would |
13 |
like to contribute an installation script, we would welcome it!) |
14 |
|
15 |
1. Easiest "installation" - use our pre-built VM image! |
16 |
|
17 |
The easiest way to get Mininet running is to start with one of our pre-built |
18 |
virtual machine images from http://openflow.org/mininet |
19 |
|
20 |
Boot up the VM image, log in, and follow the instructions on the wiki page. |
21 |
|
22 |
One advantage of using the VM image is that it doesn't mess with |
23 |
your native OS installation or damage it in any way. |
24 |
|
25 |
Although a single Mininet instance can simulate multiple networks with |
26 |
multiple controllers, only one Mininet instance may currently be run at |
27 |
a time, and Mininet requires root access in the machine it's running on. |
28 |
Therefore, if you have a multiuser system, you may wish to consider |
29 |
running Mininet in a VM. |
30 |
|
31 |
2. Next-easiest option: use our Ubuntu package! |
32 |
|
33 |
To install Mininet itself (i.e. mn and the Python API) on Ubuntu 12.10+ |
34 |
|
35 |
sudo apt-get install mininet |
36 |
|
37 |
Note: if you are upgrading from an older version of Mininet, make sure you |
38 |
remove the old OVS from /usr/local: |
39 |
|
40 |
sudo rm /usr/local/bin/ovs* |
41 |
sudo rm /usr/local/sbin/ovs* |
42 |
|
43 |
3. Native installation from source on Ubuntu 11.10+ |
44 |
|
45 |
If you're reading this, you've probably already done so, but the command to |
46 |
download the Mininet source code is; |
47 |
|
48 |
git clone git://openflow.org/mininet.git |
49 |
|
50 |
If you are running Ubuntu, you may be able to use our handy install.sh script, |
51 |
which is in mininet/util. |
52 |
|
53 |
WARNING: USE AT YOUR OWN RISK! |
54 |
|
55 |
install.sh is a bit intrusive and may possibly damage your OS and/or |
56 |
home directory, by creating/modifying several directories such as |
57 |
mininet, openflow, openvswitch and noxcore. Although we hope it won't |
58 |
do anything completely terrible, you may want to look at the script |
59 |
before you run it, and you should make sure your system and home |
60 |
directory are backed up just in case! |
61 |
|
62 |
To install Mininet itself, the OpenFlow reference implementation, and |
63 |
Open vSwitch, you may use: |
64 |
|
65 |
$ mininet/util/install.sh -fnv |
66 |
|
67 |
This should be reasonably quick and the following command should work |
68 |
after the installation: |
69 |
|
70 |
$ sudo mn --test pingall |
71 |
|
72 |
To install ALL of the software which we use for OpenFlow tutorials, |
73 |
including NOX classic, the OpenFlow WireShark dissector, the oftest |
74 |
framework, and other potentially useful software (and to add some stuff |
75 |
to /etc/sysctl.conf which may or may not be useful) you may use |
76 |
|
77 |
$ mininet/util/install.sh -a |
78 |
|
79 |
This takes about 20 minutes on our test system. |
80 |
|
81 |
4. Creating your own Mininet/OpenFlow tutorial VM |
82 |
|
83 |
Creating your own Ubuntu Mininet VM for use with the OpenFlow tutorial |
84 |
is easy! First, create a new Ubuntu VM. Then, run |
85 |
|
86 |
$ wget https://raw.github.com/mininet/mininet/util/vm/install-mininet-vm.sh |
87 |
$ time install-mininet-vm.sh |
88 |
|
89 |
5. Installation on other Linux distributions |
90 |
|
91 |
Although we don't support other Linux distributions directly, it should be |
92 |
possible to install and run Mininet with some degree of manual effort. |
93 |
|
94 |
In general, you must have: |
95 |
|
96 |
* A Linux kernel compiled with network namespace support enabled |
97 |
|
98 |
* An OpenFlow implementation (either the reference user or kernel |
99 |
space implementations, or Open vSwitch.) Appropriate kernel modules |
100 |
(e.g. tun and ofdatapath for the reference kernel implementation) must |
101 |
be loaded. |
102 |
|
103 |
* Python, `bash`, `ping`, `iperf`, etc. |
104 |
|
105 |
* Root privileges (required for network device access) |
106 |
|
107 |
We encourage contribution of patches to the `install.sh` script to support |
108 |
other Linux distributions. |
109 |
|
110 |
Good luck! |
