我已经部署了一个rails应用程序,允许用户上传照片并将其显示在另一个页面上,相当简单。我在开发中测试了它,图像上传到公共文件夹并正确显示。在生产中并将图像上传到服务器但未在页面上呈现。
仅针对我上传的图片出现404错误,路径如下所示:
http://IP-OF-APP/uploads/blog/name-of-image.jpg
我读了另一个S.O.文章提到将生产配置serve_static_files设置为true。这并没有解决问题。
我认为这可能是一个服务器配置,NGINX没有选择上传路径,这是我的/sites-default/nginx.conf文件。
upstream app {
server unix: /home/deploy/MYAPPNAME/shared/tmp/sockets/puma.sock fail_timeout=0;
}
server {
listen 80;
server_name IP_ADDRESS_OF_SERVER;
root /home/deploy/MYAPPNAME/public;
location @app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_pass http://app;
proxy_redirect off;
}
location ~ ^/(assets)/ {
root /home/deploy/MYAPPNAME/shared/public
gzip_static on;
expires max;
add_header Cache-Control public;
}
location ~ ^/uploads/ {
root /home/deploy/MYAPPNAME/shared/public;
expires 24h;
add_header Cache-Control public;
break;
}
location ~ ^/(fonts|system)/favicon.ico/robots.txt {
gzip_static on;
expires max;
add_header Cache-Control public;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 4G;
keepalive_timeout 10;
}
我还认为图片可能无法正确上传到服务器,因此我将SSH连接到服务器并找到上传的图片:
home/deploy/MYAPPNAME/shared/public/uploads/blog/name-of-image.jpg
还发现我认为是相同的图像:
home/deploy/MYAPPNAME/current/public/uploads/blog/name-of-image.jpg
我的上传器看起来像这样:
class BlogUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
storage :file
def store_dir
'uploads/blog'
end
def extension_whitelist
%w(jpg jpeg gif png)
end
process :resize_to_fit => [825, 825]
#titles are validated to be unique
def filename
"#{model.title}"+".#{file.extension}" if original_filename.present?
end
end
使用
Rails 4.2.6
Ruby 2.3.0
Carrierwave 0.11.0
修改
所有其他静态图像,CSS和JS正在正确显示和呈现。
重新上传图片时出现NGINX错误:
2016/04/29 17:32:34 [error] 4993#0: *23 open() "/home/deploy/MYAPPNAME/shared/public/assets/uploads/blog/name-of-image.jpg" fails (2: no such file or directory), client: *******, server: SERVER_IP, request: "GET /assets/uploads/blog/name-of-image.jpg HTTP/1.1", host: "SERVER_IP"
答案 0 :(得分:1)
用户正在请求:
/assets/uploads/blog/name-of-image.jpg
Nginx正在寻找图片:
/home/deploy/MYAPPNAME/shared/public/assets/uploads/blog/name-of-image.jpg
您确认图片位于:
home/deploy/MYAPPNAME/shared/public/uploads/blog/name-of-image.jpg
Nginx正在查看public/assets/uploads
,您的文件位于public/uploads
。
