[英]How to run Python Code in mininet
I write a simple topology with Python in mininet, but I dont know how to execute my code,I searched in internet and find several methods. 我在mininet中用Python写了一个简单的拓扑,但是我不知道如何执行我的代码,我在互联网上搜索并找到了几种方法。 which one is correct?
哪一个是正确的? And what is the difference between them?
它们之间有什么区别?
Method 1: 方法1:
sudo mn --custom ~/mininet/custom/filename.py --topo mytopo
Method 2: 方法2:
sudo phython filename.py
Method 3: 方法3:
chmod u+x filename.py sudo ./filename.py
Method 1 is the classical method to deploy a custom topology in Mininet. 方法1是在Mininet中部署自定义拓扑的经典方法。 You can specify in the same command the controller, like this :
您可以在同一命令中指定控制器,如下所示:
sudo mn --custom ~/mininet/custom/filename.py --topo mytopo --controller=remote,ip=[CONTROLLER_IP],port=6633
or if you don't, Mininet will use the default. 否则,Mininet将使用默认值。
Method 2 executes the [FILENAME]
file. 方法2执行
[FILENAME]
文件。 Note that here you have to specify the controller which you will use inside the python script . 请注意, 您必须在此处指定将在python脚本中使用的控制器 。 This is the difference with Method 1.
这与方法1有所不同。
Method 3 makes the [FILENAME]
file executable with the first command, and then executes it. 方法3使用第一个命令使
[FILENAME]
文件可执行,然后执行它。 It is the same as Method 2. 它与方法2相同。
