部署分佈式存儲系統FastDFS（續一）

今天設置nginx代理，代理存儲服務的http訪問。

在沒有代理前，咱們上傳了圖片，須要使用group中的任一storage server進行訪問，若是是多group，很麻煩。

新增一臺虛擬機，部署nginx環境，參考網上教程。

nginx配置文件以下（包含了簡單的防盜鏈功能）：

user www-data;

worker_processes 4;

pid /run/nginx.pid;

events {

worker_connections 768;

# multi_accept on;

}

http {

include mime.types;

default_type application/octet-stream;

server_names_hash_bucket_size 128;

client_header_buffer_size 32k;

large_client_header_buffers 4 32k;

client_max_body_size 300m;

sendfile on;

tcp_nopush on;

keepalive_timeout 120;

gzip on;

gzip_min_length 1k;

gzip_buffers 4 16k;

gzip_http_version 1.0;

gzip_comp_level 2;

gzip_types text/plain applicatin/x-javascript text/css application/xml;

gzip_vary on;

gzip_disable "MSIE[1-6]."

proxy_redirect off;

#當後端單臺web服務器上配置有多個虛擬主機時，須要使用該Header來區分反向代理哪一個主機名

proxy_set_header Host $http_host;

proxy_set_header X-Real-IP $remote_addr;
