NGINX + uWSGI被连接重置(NGINX + uWSGI Connection Reset

2019-07-02 13:58发布

我试图使用主机上uWSGI NGINX瓶的应用。

这里是我的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;
    }

我因为这样运行uwsgi

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

我使用POST请求。 对于使用开发HTTP客户端。 当我发送请求肚里无限

http://localhost/myapp

uWSGI服务器接收该请求,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的错误日志

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?

Answer 1:

没有在应用程序中阅读它您不能从客户端的数据。 虽然这不是在uWSGI问题,nginx的将失败。 你可以用“假”使用uWSGI的--post缓冲选项,从插座(如果可用)自动读取DATAS,但你最好要“修理”(即使我不认为这是一个错误)的东西你应用



Answer 2:

确保消费应用程序中的您的文章数据

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")

Answer 3:

当一个请求的主体没有被消耗,就会出现此问题,因为uwsgi无法知道它是否仍然会在某些时候是必要的。 所以uwsgi将继续保持到数据,直至其被消耗或直到nginx的重置连接(因为上游超时)。

uwsgi的作者解释它在这里 :

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,要解决这个问题,你需要确保始终无论是读取整个请求体或不发送体,如果它是没有必要的(对于DELETE EG)。



Answer 4:

不使用线程!

我有同样的问题与全球解释器锁在Python下uwsgi。 当我不使用threads-不连接复位。

uwsgi配置的实施例(1GB内存在服务器上)

[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
    post-buffering: 8192
