使用openresty && minio && thumbor 構建穩定高效的圖片服務器

備註：

     minio 是一個開源的s3 協議兼容的分佈式存儲，openresty nginx+lua 高性能可擴展的nginx 衍生版，thumbor 基於python

的圖片處理服務器，支持圖片的裁剪，識別。。。。

     代碼爲使用docker 構建的一個一體化的參考代碼，實際使用中，你們能夠基於本身的業務場景修改，對於簡單的場景，直接

使用也是能夠的。

1. 項目結構

├── Dockerfile-nginx
├── Dockerfile-thumbor
├── README.md
├── docker-compose.yml
└── nginx.conf

2. 代碼說明

備註：主要是對於docker-compose.yml的說明

a. docker-compose.yml

version: '3'
services:
  nginx:
    image: mynginx-minio
    build:
      context: .
      dockerfile: Dockerfile-nginx
    ports:
      - 8087:80
    depends_on:
      - thumbor
  thumbor:
    image: mythumbor
    build:
      context: .
      dockerfile: Dockerfile-thumbor
  minio:
    image: minio/minio
    volumes:
      - ./data:/data
      - ./config:/root/.minio
    ports:
      - 9091:9000
    command: server /data

b. Dockerfile-nginx 很簡單，就是進行反向代理的配置

FROM openresty/openresty:alpine
LABEL name="rongfengliang"
LABEL version="v1.0.0"
ENV name=rongfengliang
ENV version=v1.0.0
COPY nginx.conf usr/local/openresty/nginx/conf/
EXPOSE 80
EXPOSE 443
EXPOSE 88

nginx.conf

    worker_connections  1024;

    real_ip_recursive on;
    server {
        listen       80;
        server_name  localhost;
        real_ip_header    X-Forwarded-For;
        real_ip_recursive on;
        charset utf-8;
        location /mydemo{
            root   html;
            proxy_set_header Host $http_host;

            proxy_buffers 1024 4k;
            proxy_read_timeout 300;
            proxy_pass http://minio:9000; 
        }
        location /{
            proxy_set_header Host $http_host;
            proxy_set_header X-Forwarded-For $remote_addr;
            client_body_buffer_size 10M;
            client_max_body_size 10G;
            proxy_buffers 1024 4k;
            proxy_read_timeout 300;
            proxy_pass http://thumbor/unsafe/300x200/http://minio:9000$request_uri; // 圖片處理爲300*200 的大小
        }
        location /alert {
         default_type text/html;
         content_by_lua_block{
             ngx.say([[<script>alert("error")</script>]])
         }
        }
        location /ip {
            default_type text/html;
            content_by_lua_block{
                ngx.say(ngx.var.remote_addr)
            }
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
    server {
        listen       88;
        server_name  localhost;
        charset utf-8;
        location / {
            root   html;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

c. Dockerfile-thumbor thumbor 的鏡像

FROM alpine:3.6
EXPOSE 80
MAINTAINER dalong@qq.com
CMD ["thumbor", "-l", "info", "-p", "80"]
ENV THUMBOR_VERSION 6.3.2
RUN apk add --no-cache \
		python \
    libcurl \

    libressl-dev \
	&& export LIBRARY_PATH=/lib \
	&& pip install thumbor==$THUMBOR_VERSION \
	&& apk del gcc *-dev \
	&& rm -rf /var/cache/apk/* \
	&& rm -rf /root/.cache

3. 構建

docker-compose build

4. 運行

docker-compose up -d

5. 準備運行數據（minio 文件，以及policy 配置）

a. 獲取minio key

dokcer-compose logs  minio

b. 輸入minio 登錄須要的key 

c. 建立bucket

d. 設置bucket policy  *  read&&write
