有没有办法让 EC2 实例中的请求保持超过 60 秒？

Question

大家好，我一直在尝试在亚马逊 aws ec2 实例上执行我们的 django 应用程序。一切正常，除了超过 60 秒的请求。这些请求会自动获得504 Gateway Time-out。我在安全组中为我的 EC2 实例配置了所有需要的端口。 我们正在使用 nginx，我的 nginx.conf 看起来像：

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}
http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  3600s;

    client_max_body_size 500M;
    client_body_timeout 86400s;
    client_header_timeout 86400s;
    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
    proxy_connect_timeout 86400s;
    proxy_send_timeout 86400s;
    proxy_read_timeout 86400s;
    send_timeout 86400s;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

我尝试使用keepalive_timeout，正如许多帖子所建议的那样，但它不起作用。也有很多帖子提到负载均衡器配置，但我什至没有使用负载均衡器，所以这应该与它无关。

如何管理我的实例以处理超过 60 秒的请求？

更新：

通过在 django 容器中搜索 server { } 块来解决（如 @jaygooby 建议的那样）。我修改了/etc/nginx/sites-enabled/mydjango 并将proxy_read_timeout 60m; 添加到我的````location / { }``` 块中。

我建议先整理一下你的配置；您在设置一些值时不了解它们的真正用途，然后包含另一个配置文件，然后设置更多，然后包含更多配置。

更改它以便您执行包含并然后覆盖您想要的值。

我已对各种设置进行了注释，以便您了解它们的用途；这些经常被货物崇拜复制，希望它们能奏效。唯一真正需要像86400s（24 小时！）这样的东西是proxy_read_timeout：

我怀疑发生的事情是/etc/nginx/conf.d/*.conf 中的一个 conf 文件有一个60s（或1m）设置为proxy_read_timeout，即使你给了这个更大的值，你也调用了@ 987654327@ 再次覆盖您的设置。

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}
http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;

    client_max_body_size 500M;    # Don't allow uploads larger than 500MB
