nginx文件上传冻结答案

【问题标题】：nginx file upload freezesnginx文件上传冻结

【问题描述】：

我正在测试一个 django 网站部署。当我直接连接到我的 gunicorn localhost 并在调试模式下运行它（以便 django 自己处理文件上传）时，该站点可以正常工作。当我通过 nginx 关闭调试模式访问站点时（它绑定到同一个 gunicorn localhost），除了文件上传之外，一切正常。每当我尝试上传大于 1MB 的文件时，上传都会冻结（对于 1.3MB 的文件，我的浏览器会冻结在 70%）。

我已将 nginx 安装到 conda 虚拟环境 (conda install --no-update-dependencies -c anacoda nginx) 中。这是etc/nginx.conf 文件：

# nginx Configuration File
# https://www.nginx.com/resources/wiki/start/topics/examples/full/
# http://nginx.org/en/docs/dirindex.html
# https://www.nginx.com/resources/wiki/start/

# Run as a unique, less privileged user for security.
# user nginx www-data;  ## Default: nobody

# If using supervisord init system, do not run in deamon mode.
# Bear in mind that non-stop upgrade is not an option with "daemon off".
# daemon off;

# Sets the worker threads to the number of CPU cores available in the system
# for best performance.
# Should be > the number of CPU cores.
# Maximum number of connections = worker_processes * worker_connections
worker_processes auto;  ## Default: 1

# Maximum number of open files per worker process.
# Should be > worker_connections.

  worker_connections 8000;
}

# Log errors and warnings to this file

  sendfile on;

  # Don't send out partial frames; this increases throughput
  # since TCP frames are filled up before being sent out.
  tcp_nopush on;

  # Enable gzip compression.
  gzip on;

  # Compression level (1-9).
  # 5 is a perfect compromise between size and CPU usage, offering about
  # 75% reduction for most ASCII files (almost identical to level 9).
  gzip_comp_level 5;

  # Don't compress anything that's already small and unlikely to shrink much
  # if at all (the default is 20 bytes, which is bad as that usually leads to
  # larger files after gzipping).
  gzip_min_length 256;

  # Compress data even for clients that are connecting to us via proxies,
  # identified by the "Via" header (required for CloudFront).
  gzip_proxied any;

  # Tell proxies to cache both the gzipped and regular version of a resource

  # This should be turned on if you are going to have pre-compressed copies (.gz) of

  # a specific directory, or on an individual server{} level.
  # gzip_static on;

  include conf.d/*.conf;
}

这是我的服务器配置文件的原始版本 (conf.d/test.conf)。

server {
    server_name localhost;
    listen      8081;
    access_log on;
    client_max_body_size 32M;
    send_timeout 100s;

    location /static/ {
        alias /Users/user/static/;
        autoindex on;
        error_log /Users/user/.nginx/labsite.static.error.log warn;
    }

    location /media/ {
        alias /Users/user/media/;
        autoindex on;
        error_log /Users/user/.nginx/labsite.media.error.log warn;
    }

    location / {
            proxy_pass http://localhost:8001;
            proxy_set_header X-Forwarded-Host $server_name;
            proxy_set_header X-Real-IP $remote_addr;
            add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"';
    }
    access_log      /Users/user/.nginx/labsite.access.log combined;
    error_log       /Users/user/.nginx/labsit.error.log warn;
}

我找到了几个相关的帖子：

他们让我介绍了一些修改

server {
    server_name localhost;
    listen      8081;
    access_log on;
    client_max_body_size 32M;
    send_timeout 300s;
    gzip_static off;

    location /static/ {
        alias /Users/user/static/;
        autoindex on;
        error_log /Users/user/.nginx/labsite.static.error.log warn;
    }

    location /media/ {
        alias /Users/user/media/;
        client_body_temp_path /Users/user/media;
        autoindex on;
        error_log /Users/user/.nginx/labsite.media.error.log warn;
    }

    location / {
            proxy_pass http://localhost:8001;
            proxy_set_header X-Forwarded-Host $server_name;
            proxy_set_header X-Real-IP $remote_addr;
            add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"';
    }
    access_log      /Users/user/.nginx/labsite.access.log combined;
    error_log       /Users/user/.nginx/labsit.error.log warn;
}

我也尝试在我的配置文件中设置sendfile off，因为这是推荐用于 Free BSD（Mac OS X 基于 Free BSD），但无济于事。我错过了什么吗？

【解决方案1】：

看来，我已经想通了。我不得不更改临时目录（我不完全确定原因，因为没有与权限相关的问题）并设置/增加 client_body_timeout 参数。

server {
    listen 8081;
    server_name localhost;
    client_max_body_size 32M;
    client_body_timeout 300s;
    send_timeout 300s;
    client_body_temp_path /Users/user/media;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /Users/user;
    }
    location /media/ {
        root /Users/user;
    }
    location / {
        proxy_pass http://localhost:8001;
        proxy_set_header X-Forwarded-Host $server_name;
        proxy_set_header X-Real-IP $remote_addr;
        add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"';
    }
}
