在rails 3.2中使用nginx而不是rails来提供static_assets
我最近部署了一个基于SpreeCommerce平台的网站。 我正在使用nginx，并希望nginx能够提供我的静态资产。 我遇到的问题是，当用户在网站上为产品上传新照片时，图像看起来可以正确保存（文件位于服务器上），但它们不会被提供给浏览器。
我可以通过将production.rb更改为config.serve_static_assets = true而不是false并将图片重新上传到现有产品来暂时解决此问题。 但是这有资源而不是nginx服务 – 而不是我想要发生的事情。
这是我目前的nginx配置文件：
user spree; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 1024; multi_accept on; } http { types_hash_bucket_size 512; types_hash_max_size 2048; sendfile on; tcp_nopush on; tcp_nodelay off; include /etc/nginx/mime.types; default_type application/octet-stream; access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; gzip on; gzip_disable "msie6"; gzip_proxied any; gzip_min_length 500; gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; }
然后我的/ etc / nginx / sites-enabled / [我的应用程序名称]：
upstream 50.57.75.156 { # fail_timeout=0 means we always retry an upstream even if it failed # to return a good HTTP response (in case the Unicorn master nukes a # single worker for timing out). # for UNIX domain socket setups: server unix:/tmp/angel_wood.socket fail_timeout=0; } server { # if you're running multiple servers, instead of "default" you should # put your main domain name here listen 80 default; # you could put a list of other domain names this application answers server_name 50.57.75.156; root /home/spree/angel_wood/current/public; access_log /var/log/nginx/50.57.75.156_access.log; rewrite_log on; location / { #all requests are sent to the UNIX socket proxy_pass http://50.57.75.156; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } # if the request is for a static resource, nginx should serve it directly # and add a far future expires header to it, making the browser # cache the resource and navigate faster over the website # this probably needs some work with Rails 3.1's asset pipeline location ~ ^/(system|assets)/ { root /home/spree/angel_wood/current/public; expires max; break; } }
另外，供参考 – 这是在服务器上保存图像时的日志：

关于向nginx发出指令以使其为我的资产提供服务，我有些不明白的事情。 有谁看到我在这里做错了什么？
通过更改location线来解决此问题：
location ~ ^/(system|assets)/ {
对此：
location ~ ^/(spree|system|assets)/ {
这是因为资产位于“spree”目录内的公共根目录中。 “system”是典型Paperclip上传的地方，资产是Rails资产。
