我网站上的一个页面需要在服务器上进行长时间的计算(约2分钟)。如果我在localhost上运行网站,则工作正常。但是在生产的时候〜30秒。这是Nginx conf的http部分:
http {
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;
tcp_nodelay on;
keepalive_timeout 120;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf;
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _;
root /usr/share/nginx/html;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
proxy_read_timeout 300;
proxy_connect_timeout 300;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
我尝试添加:
fastcgi_read_timeout 300;
proxy_read_timeout 300;
最后(在“服务器”之后),但是它什么也没做。

如果收到502 Bad Gateway错误,则表明您的应用程序服务器(我猜是根据您的标签,它是Unicorn)正在发送超时而不是Nginx,您应该在生产服务器中的unicorn.rb
文件中增加超时时间
worker_processes 2
listen "/tmp/xxx.socket"
##equal to your proxy read timeout in the Nginx config.
timeout 300
pid "/tmp/unicorn.xxx.pid"
对于Python Green Unicorn,请执行以下操作:
NUM_WORKERS=3
TIMEOUT=300
exec gunicorn ${DJANGO_WSGI_MODULE}:application \
--name $NAME \
--workers $NUM_WORKERS \
--timeout $TIMEOUT \
--log-level=debug \
--bind=x.x.x.x \
--pid=$PIDFILE
