nox controller 错误 nox_core报错解决办法

安装完controller所需的所有依赖软件后nox_core未启动

手动启动如下：

cd  /opt/nox/bin

./nox_core

报如下错误

OX 0.4.1~beta+build2 (nox_core), compiled Feb  6 2011 07:40:04
Compiled with OpenFlow 0x01
00001|snac|ERR:Cannot change the state of 'python' to INSTALLED:
'python' ran into an error:
 Unable to construct a Python component:
 Traceback (most recent call last):
   File "./nox/apps/pyrt/pyoxidereactor.py", line 336, in instance
   File "./nox/apps/pyrt/pyoxidereactor.py", line 104, in __init__
 AttributeError: 'pyoxidereactor' object has no attribute '_handleSigchld

办法如下

vim /usr/lib/python2.6/dist-packages/twisted/internet/base.py

在最后倒数第二行加入

def _handleSigchld(self, signum, frame, _threadSupport=platform.supportsThreads()): 

       from twisted.internet.process import reapAllProcesses 

     if _threadSupport: 

         self.callFromThread(reapAllProcesses)

    else: 

         self.callLater(0, reapAllProcesses)

注意和文件中的格式保持对齐  python对格式要求很严格
