nginx - 使用 nginx/puma 下载 Rails 5.2.1 ActiveStorage 文件被截断
问题描述
我的第一个ActiveStorage项目在开发(仅限 puma)上运行良好,但在生产(nginx/puma)上,我在下载显示为截断文件的大文件时遇到问题。
例如,一个大小为 24.1 MB 的上传文件提供 5 MB(截断)的下载。
我主要上传 pdf 文件,上传的文件是完整的(在服务器上检查)& 预览工作正常。
所有环境都使用config.active_storage.service = :local
配置/存储.yml
local:
service: Disk
root: <%= Rails.root.join("storage") %>
下载网址是使用生成的rails_blob_path(document.doc, disposition: :inline)
我怀疑 puma 或 nginx 中有一个选项或参数导致下载完整文件失败。截至目前,我在日志中看不到任何错误。
/etc/nginx/sites-available/default.conf
upstream app {
# Path to Puma SOCK file, as defined previously
server unix:/home/deploy/rails/shared/sockets/puma.sock fail_timeout=0;
}
server {
listen 80;
root /home/deploy/rails/public;
try_files $uri/index.html $uri @app;
# Make site accessible from http://localhost/
server_name localhost;
location @app {
proxy_pass http://app;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
}
error_page 500 502 503 504 /500.html;
keepalive_timeout 10;
client_max_body_size 4G;
}
Rails 配置/puma.rb
# Default to production
rails_env = ENV['RAILS_ENV'] || "production"
environment rails_env
# Change to match your CPU core count
if rails_env == 'production'
workers 2
else
workers 1
end
# Min and Max threads per worker
threads 1, 6
app_dir = File.expand_path("../..", __FILE__)
shared_dir = "#{app_dir}/shared"
if rails_env == 'production'
# Set up socket location
bind "unix://#{shared_dir}/sockets/puma.sock"
# Logging
stdout_redirect "#{shared_dir}/log/puma.stdout.log", "#{shared_dir}/log/puma.stderr.log", true
# Set master PID and state locations
pidfile "#{shared_dir}/pids/puma.pid"
state_path "#{shared_dir}/pids/puma.state"
activate_control_app
on_worker_boot do
require "active_record"
ActiveRecord::Base.connection.disconnect! rescue ActiveRecord::ConnectionNotEstablished
ActiveRecord::Base.establish_connection(YAML.load_file("#{app_dir}/config/database.yml")[rails_env])
end
end
解决方案
利用proxy_http_version 1.1;
默认情况下,nginx 使用 HTTP 1.0 进行代理,不支持分块传输编码。
