python - 让 flup fcgi 脚本正常工作很困难

Question

我正在使用 django 为客户构建一个网站。它托管在共享主机上，无法使用 mod_wsgi。去年，我使用 fcgi 让它工作，但是当我回来时，它坏了。

我用一个简单的 hello world 脚本替换了 fcgi 脚本:

#!/usr/bin/python
def myapp(environ, start_response):
    start_response('200 OK', [('Content-Type', 'text/plain')])
    return ['Hello World!\n']

try:
    from flup.server.fcgi import WSGIServer
    WSGIServer(myapp).run()
except:
    import sys, traceback
    traceback.print_exc(file=open("errlog.txt","a"))

在我的本地服务器上测试并工作，但在托管服务器上，我收到此错误:

<title>FCGI Error</title>
A timeout occured while waiting for the script output (in: /usr/www/users/mymemb/).

如果我查看错误日志，我会看到以下内容:

[Wed Jan  6 16:59:37 2010] [warn] FastCGI: (dynamic) server "/usr/www/users/mymemb/mymembers.fcgi" has failed to remain running for 30 seconds given 3 attempts, its restart interval has been backed off to 10 seconds

etc ...

如果我通过 ssh 连接到服务器，我可以正常运行脚本，并输出以下内容:

mymemb@www81:~/public_html$ ./mymembers.fcgi 
WSGIServer: missing FastCGI param REQUEST_METHOD required by WSGI!
WSGIServer: missing FastCGI param SERVER_NAME required by WSGI!
WSGIServer: missing FastCGI param SERVER_PORT required by WSGI!
WSGIServer: missing FastCGI param SERVER_PROTOCOL required by WSGI!
Status: 200 OK
Content-Type: text/plain
Content-Length: 13

Hello World!

如何解决这个问题？

添加信息:

脚本似乎根本没有运行。如果我在脚本顶部添加 import x 并从 ssh 运行它，我会看到 x.pyc 被创建。如果我 rm x.pyc，然后点击该站点，则不会创建 x.pyc。

我还注意到错误从

terminated by calling exit with status '118'

到

terminated by calling exit with status '116'

我希望能够找到这些退出状态的引用。

Answer 1

退出状态 116 和 118 来自 suexec。通过阅读source code ，我发现这些错误是由组或其他人可写文件/目录引起的，suexec 认为这是一个安全问题。从组中删除写入权限修复了问题。
