Nginx 504 Gateway Timeout

Question

I am running a rails3.0.7 project with a phusion passenger on nginx. While I was doing ajax, which took about 15 minutes to process. He jumped in error with firebug, which said “504 Gateway Time-out” 10 minutes after ajax call.

Can someone give me some idea how I can find the problem.

Thanks ben

Answer 1

This is a nginx timeout error. Take a look at the following article for some hints as to which parameter you need to configure in order to avoid a timeout if you really want to allow more than 10 minutes to complete the task.

How to prevent gateway timeout with nginx

Answer 2

I had a similar problem with Rails 4 on Mac OS X (Yosemite). Therefore, I added the following to my specific Nginx location.

proxy_connect_timeout 43200000; proxy_read_timeout 43200000; proxy_send_timeout 43200000; 

So, my general configuration for Nginx is as below.

 location /my_sub_path/ { root /my/rails/project/public/folder/path proxy_http_version 1.1; chunked_transfer_encoding off; proxy_buffering off; proxy_cache off; proxy_connect_timeout 43200000; proxy_read_timeout 43200000; proxy_send_timeout 43200000; proxy_redirect off; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Proto $scheme; proxy_pass http://127.0.0.1:3000/; }

This is a problem from the phusion passenger. You must modify the file: (gems> passenger-3.0.18> ext> nginx> Configuration.c)

 ngx_conf_merge_msec_value(conf->upstream_config.send_timeout, prev->upstream_config.send_timeout, 6000000); ngx_conf_merge_msec_value(conf->upstream_config.read_timeout, prev->upstream_config.read_timeout, 6000000); 

The occurrence timeout is 600,000, only 10 minutes. I tried changing nginx.conf but it did not work.
