Before asking this question, I searched Google and everywhere for hours trying to increase the connection timeout between Varnish 4 and Nginx but found no solution.
So here is my Varnish Config:
backend web1 {
.host = "192.168.1.21";
.port = "80";
.probe = {
.request =
"HEAD / HTTP/1.1"
"Host: localhost"
"Connection: close";
.timeout = 1s;
.interval = 5s;
.window = 5;
.threshold = 3;
}
.connect_timeout = 300s;
.between_bytes_timeout = 300s;
}
And this is Nginx config:
http {
##
# Basic Settings
##
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 0; # wait for 5 minutes before timeout the request
# proxy_connect_timeout 60s;
# proxy_send_timeout 300s;
# proxy_read_timeout 300s;
fastcgi_read_timeout 300s;
types_hash_max_size 2048;
# server_tokens off;
client_body_buffer_size 20m; #Buffer of post request
client_header_buffer_size 2k; #Buffer of headers
client_max_body_size 40m; #Max post request size
large_client_header_buffers 20 2k; #Max number and size of buffers of large requests
server_names_hash_bucket_size 64;
# server_name_in_redirect off;
include /etc/nginx/mime.types;
default_type application/octet-stream;
##

error_log /var/log/nginx/error.log;

# gzip_vary on;
# gzip_proxied any;
# gzip_comp_level 6;
# gzip_buffers 16 8k;
# gzip_http_version 1.1;
# gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
##
# nginx-naxsi config
##
# Uncomment it if you installed nginx-naxsi
##
#include /etc/nginx/naxsi_core.rules;
##
# nginx-passenger config
##
# Uncomment it if you installed nginx-passenger
##
#passenger_root /usr;
#passenger_ruby /usr/bin/ruby;
##
# Virtual Host Configs
##
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}
I tried all parameters but nothing works.
When I set keepalive_timeout
to 300s, if I access it directly, the timeout is set to 300s (5 minutes) but when I access through Varnish, timeout is set to 60s. So I disabled the Nginx keepalive_timeout
and setting it to 0, but got the same problem.
What's wrong?
How can I increase timeout between Varnish and Nginx?
As answers to this question point out: https://serverfault.com/questions/573169/varnish-503-error-after-exactly-60-seconds-how-to-change-this-timeout-value
The problem seems to be the .first_byte_timeout
parameter in the VCL, by default it is only 60 seconds.
Set the first byte timeout to 300s:
.first_byte_timeout = 300s;
