我正在尝试使用 lighttpd 和 fastcgi 来运行一个小型 flask 应用程序。当我尝试启动 lighttpd 时，它可以正常启动服务器，但是当我尝试在浏览器中连接时，它会挂起而没有给出任何有意义的错误消息。
我在 Raspberry Pi 3 上运行它。操作系统是 Raspbian Stretch Lite。
这是 lighttpd 日志输出。

您可以看到我按下 CTRL C 来终止进程的位置。如您所见，我在此日志中找不到任何有意义的错误消息。此日志显示第一行2018-01-04 19:56:16: (log.c.217) server started，然后我转到浏览器中的 URL（即服务器的本地 IP）。但是，在我的浏览器中什么也没有发生，直到我终止该进程。然后我收到 500 内部服务器错误消息（在浏览器中）。
这是我的 fastcgi 脚本。
#!/usr/bin/python3
from flup.server.fcgi import WSGIServer
from modules import app
if __name__ == '__main__':
WSGIServer(app).run()
这是我的 lighttpd.conf 文件。
server.modules += ( "mod_fastcgi" )
server.modules += ( "mod_rewrite" )
fastcgi.debug = 1
debug.log-request-handling = "enable"
debug.log-file-not-found = "enable"
server.username = "lighttpd"
server.groupname = "lighttpd"
server.document-root = "/var/www/"
server.port = 80
$SERVER["socket"] == ":80" {
mimetype.assign = (
".html" => "text/html"
)
url.rewrite-once = (
"^(/modules/static($|/.*))$" => "$1",
"^(/.*)$" => "/application.fcgi$1"
)
$HTTP["host"] =~ "$" {
server.document-root = "/var/www/"
fastcgi.server = ( "application.fcgi" =>
(( "socket" => "/tmp/fastcgi.socket",
"bin-path" => "/home/pi/timeclock_venv/bin/python3 /var/www/TimeClock/application.fcgi",
"max-procs" => 1,
"bin-environment" => (
"REAL_SCRIPT_NAME" => ""
),
"check-local" => "disable"
))
)
}
}
在我的 lighttpd 脚本中，我使用 virtualenv 目录中的 python3 解释器，它具有我的 flask 应用程序所需的所有依赖项。
请给予我任何您认为必要的帮助或建议，以使其工作正常，谢谢。
更新
我发现，有时 lighttpd 确实会给我回溯，但这不是完整的回溯。以下是我得到的。
