RYU openflow控制器错误与python一起记录

Question

我在一台ubuntu机器上执行“python./setup.py install”之后很有趣，当openflow控制器启动时，我看到了一个绑定错误。我仔细检查了一下，没有应用程序或服务占用端口"8080“

ryu-manager ryu/app/ofctl_rest.py
loading app ryu/app/ofctl_rest.py
loading app ryu.controller.ofp_handler
instantiating app None of DPSet
creating context dpset
creating context wsgi
instantiating app ryu.controller.ofp_handler of OFPHandler
instantiating app ryu/app/ofctl_rest.py of RestStatsApi
hub: uncaught exception: Traceback (most recent call last):

sock.bind(addr)
File "/usr/lib/python2.7/socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
error: [Errno 98] Address already in use

现在，在另一台运行python2.6的机器上，这运行得很好

ryu-manager ~/ryu/ryu/app/ofctl_rest.py
loading app /root/ryu/ryu/app/ofctl_rest.py
loading app ryu.controller.ofp_handler
creating context dpset
creating context wsgi
instantiating app /root/ryu/ryu/app/ofctl_rest.py
instantiating app ryu.controller.ofp_handler

好的，端口8080不是争用区域，而是6633。我忘记删除我的OVS OpenFlow设置

sudo lsof -i :6633
COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
ovs-contr 1620 root    4u  IPv4   9071      0t0  TCP *:6633 (LISTEN)
