我正在尝试使用 uWSGI 在 NGINX 上托管 Bottle 应用程序。

这是我的nginx.conf

location /myapp/ {
        include uwsgi_params;
        uwsgi_param X-Real-IP $remote_addr;
        uwsgi_param Host $http_host;
        uwsgi_param UWSGI_SCRIPT myapp;
        uwsgi_pass 127.0.0.1:8080;
    }

我正在运行 uwsgi

uwsgi --enable-threads --socket :8080 --plugin python -- wsgi-file ./myApp/myapp.py

我正在使用 POST 请求。为此,使用 dev Http 客户端。当我发送请求时它会无限

http://localhost/myapp

uWSGI 服务器接收请求并打印

[pid: 4683|app: 0|req: 1/1] 127.0.0.1 () {50 vars in 806 bytes} [Thu Oct 25 12:29:36 2012] POST /myapp => generated 737 bytes in 11 msecs (HTTP/1.1 404) 2 headers in 87 bytes (1 switches on core 0)

但在 nginx 错误日志中

2012/10/25 12:20:16 [error] 4364#0: *11 readv() failed (104: Connection reset by peer) while reading upstream, client: 127.0.0.1, server: localhost, request: "POST /myApp/myapp/ HTTP/1.1", upstream: "uwsgi://127.0.0.1:8080", host: "localhost"

该怎么办?

确保在您的应用程序中使用您的帖子数据

例如,如果你有一个 Django/python 应用程序

def my_view(request):

    # ensure to read the post data, even if you don't need it
    # without this you get a: failed (104: Connection reset by peer)
    data = request.DATA

    return HttpResponse("Hello World")

如果不在应用程序中读取数据,就无法从客户端发布数据。虽然这在 uWSGI 中不是问题,但 nginx 会失败。您可以使用 uWSGI 的 --post-buffering 选项“伪造”该东西以自动从套接字读取数据(如果可用),但您最好“修复”(即使我不认为这是一个错误)您的应用程序

当请求的主体没有被消耗时,就会出现这个问题,因为 uwsgi 无法知道在某些时候是否仍然需要它。所以 uwsgi 将继续持有数据直到它被消耗或直到 nginx 重置连接(因为上游超时)。

uwsgi 的作者在这里解释:

08:21 < unbit> plaes: does your DELETE request (not-response) have a body ?
08:40 < unbit> and do you read that body in your app ?
08:41 < unbit> from the nginx logs it looks like it has a body and you are not reading it in the app
08:43 < plaes> so DELETE request shouldn't have the body?
08:43 < unbit> no i mean if a request has a body you have to read/consume it
08:44 < unbit> otherwise the socket will be clobbered

因此,要解决此问题,您需要确保始终阅读整个请求正文,或者在不需要时不发送正文(例如 DELETE)。

不使用线程!

我在 uwsgi 下的 Python 中的 Global Interpretator Lock 也有同样的问题。当我不使用线程时-不重置连接。

uwsgi 配置示例(服务器上的 1Gb Ram)

[root@mail uwsgi]# cat myproj_config.yaml 
uwsgi:
    print: Myproject Configuration Started
    socket: /var/tmp/myproject_uwsgi.sock
    pythonpath: /sites/myproject/myproj
    env: DJANGO_SETTINGS_MODULE=settings
    module: wsgi
    chdir: /sites/myproject/myproj
    daemonize: /sites/myproject/log/uwsgi.log
    max-requests: 4000
    buffer-size: 32768
    harakiri: 30
    harakiri-verbose: true
    reload-mercy: 8
    vacuum: true
    master: 1
    post-buffering: 8192
    processes: 4
    no-orphans: 1
    touch-reload: /sites/myproject/log/uwsgi
