nginx的web缓存的设置

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.37.tar.gz

wget http://labs.frickle.com/files/ngx_cache_purge-2.3.tar.gz

先安装/hcdata/software/pcre-8.37

./configure

make &&　make install

 ./configure --user=www \
> --group=www \
> --prefix=/hcdata/server/nginx \
> --with-http_stub_status_module \

> --with-http_ssl_module \
> --with-http_gzip_static_module \
> --with-openssl=/usr/local/src/openssl-1.0.1c \
> --with-pcre=/hcdata/software/pcre-8.37 \
> --with-pcre-jit \
> --add-module=/hcdata/software/ngx_cache_purge-2.3

make && make install

接着nginx.conf的配置图片的缓存

 location ~.*\.(gif|jpg|jpeg|png|bmp|swf|mp3|mp4|wmv|txt)$
    {
      proxy_cache cache_one;
      proxy_cache_valid 200 304 12h;
      proxy_cache_valid 301 302 1m;
      proxy_cache_valid any 1m;
      proxy_cache_key $host$uri$is_args$args;


    
      proxy_pass http://ip:8098;
      proxy_redirect off;
          proxy_set_header Host $host;
          proxy_set_header X-Forwarded-For $remote_addr;
    }

 server {

     listen 8098;
     server_name ip;
     location / {
       root /hcdata/www;
       autoindex on;
     }

proxy_pass 必须和proxy_cache成对出现 不然实现不了缓存

添加purge：

 location ~ /purge(/.*) {
          allow all;
          proxy_cache_purge cache_one $host$1$is_args$args;

        }

其中出现404错误 原因是此location没有放在

location ~.*\.(gif|jpg|jpeg|png|bmp|swf|mp3|mp4|wmv|txt)$ {

。。。。

}之前

正确的顺序是：

 server {
        listen       80;
        server_name  uadmin;

        charset utf-8;

        #access_log  logs/host.access.log  main;
    


     location ~ /purge(/.*) {
          allow all;
          proxy_cache_purge cache_one $host$1$is_args$args;

        }
            
    
        location ~.*\.(gif|jpg|jpeg|png|bmp|swf|mp3|mp4|wmv|txt)$
    {
      proxy_cache cache_one;
      proxy_cache_valid 200 304 12h;
      proxy_cache_valid 301 302 1m;
      proxy_cache_valid any 1m;
      proxy_cache_key $host$uri$is_args$args;

#      root /hcdata/www;
#      autoindex on;
    
      proxy_pass http://*.*.*.*:8098;
      proxy_redirect off;
          proxy_set_header Host $host;
          proxy_set_header X-Forwarded-For $remote_addr;
    }

#        proxy_cache_key $host$uri$is_args$args;

        proxy_pass http://uadmin;
    proxy_redirect off;
    proxy_set_header Host $http_host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Connection Close;
        proxy_set_header X-Forwarded-For $remote_addr;
        error_page   404              /404.html;
