linux端口使用权限

妙音 posted @ 2014年3月25日 09:55 in linux , 3281 阅读
在Linux系统中,监听1024以下端口需要root权限。因此,如果想监听80,需要使用sudo命令启动程序。
  • 示例
[wyq@localhost ~]$ python -m SimpleHTTPServer 80
Traceback (most recent call last):
  File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main
    "__main__", fname, loader, pkg_name)
  File "/usr/lib64/python2.7/runpy.py", line 72, in _run_code
    exec code in run_globals
  File "/usr/lib64/python2.7/SimpleHTTPServer.py", line 220, in <module>
    test()
  File "/usr/lib64/python2.7/SimpleHTTPServer.py", line 216, in test
    BaseHTTPServer.test(HandlerClass, ServerClass)
  File "/usr/lib64/python2.7/BaseHTTPServer.py", line 595, in test
    httpd = ServerClass(server_address, HandlerClass)
  File "/usr/lib64/python2.7/SocketServer.py", line 419, in __init__
    self.server_bind()
  File "/usr/lib64/python2.7/BaseHTTPServer.py", line 108, in server_bind
    SocketServer.TCPServer.server_bind(self)
  File "/usr/lib64/python2.7/SocketServer.py", line 430, in server_bind
    self.socket.bind(self.server_address)
  File "/usr/lib64/python2.7/socket.py", line 224, in meth
    return getattr(self._sock,name)(*args)
socket.error: [Errno 13] Permission denied

The worst part of it was that the software only worked intermittently and the data was not accurate. You obviously canot confront anyone about what you have discovered if the information is not right. 꽁머니
