本文介绍了Nginx 反向代理并缓存及缓存清除的方法，分享给大家，具体如下：

一. Nginx 配置

#user nobody;worker_processes 1;#error_log logs/error.log;#error_log logs/error.log notice;#error_log logs/error.log info;#pid    logs/nginx.pid;events {  worker_connections 1024;}http {  log_format main '$remote_addr - $remote_user [$time_local] "$request" '           '$status $body_bytes_sent "$http_referer" '           '"$http_user_agent" "$http_x_forwarded_for"'       '$upstream_addr $upstream_status $request_time $upstream_response_time';  access_log /var/log/nginx/access.log main;  error_log  /var/log/nginx/error.log;  server_tokens off;  include    mime.types;  default_type application/octet-stream;  sendfile    on;  tcp_nopush   on;  client_max_body_size 10m;  client_body_buffer_size 128k;  proxy_connect_timeout 300;  proxy_send_timeout 300;  proxy_read_timeout 300;  proxy_buffer_size 64k;  proxy_buffers 4 512k;  proxy_busy_buffers_size 512k;  proxy_temp_file_write_size 512k;  proxy_temp_path  /data/nginx/proxy_temp;  proxy_cache_path /data/nginx/proxy_cache levels=1:2 keys_zone=cache_one:2000m inactive=3d max_size=500g;  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;  gzip on;  gzip_min_length 1k;  gzip_buffers 4 16k;  gzip_http_version 1.1;  gzip_comp_level 2;  gzip_types text/plain application/x-javascript text/css application/xml;  gzip_vary on;  upstream go {    server www.cnblogs.com:80 weight=4;    #server 42.121.252.58:80 weight=4;  }  server {      listen  192.168.55.133:80;      #server_name www.cnblogs.com;      access_log /var/log/nginx/go.access.log main;      error_log  /var/log/nginx/go.error.log error;      location / {          proxy_cache cache_one;          #proxy_cache_valid 200 304 301 302 2h;          #proxy_cache_valid any 2h;          #expires 1d;          add_header X-Cache $upstream_cache_status;          proxy_pass http://go;          proxy_cache_key  $uri$is_args$args;      }      location ~ /purge(/.*) {        allow       127.0.0.1;        allow       192.168.55.0/24;        deny        all;        proxy_cache_purge cache_one $1$is_args$args;    }  }}

二. 测试

1.首次访问

 2.刷新一次，也就是第二次访问

3.缓存清理
