Nginx cache and program static and dynamic separation settings

First, configure the Nginx cache.

Reference: Http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_cache_path syntax proxy_cache_path path  [Levels=levels] keys_zone=name:size [inactive=time] [max_size=size] [loader_files=number]  [loader_sleep=time] [loader_threshold=time]; Configuration Format:proxy_cache_path /data/nginx/cache  levels=1:2 keys_zone=one:10m; #定义/data/nginx/cache for the cache directory;levels=1:2  has a Level 2 subdirectory, up to 3 levels of subdirectories, separated by a colon to define 3 numbers, Each number represents its directory name;keys_zone=one:10m  how much space is used to save the key value; 1.nginx Cache settings: Vim /data/nginx/conf/nginx.confuser nginx  nginx;worker_processes auto;pid  /data/nginx/logs/nginx.pid;worker_rlimit_nofile  65535;events {    use epoll;    worker_connections  65535;    multi_accept on;} http {    include       mime.types;     default_type  application/octet-stream;    charset   utf-8;    log_format  main   ' $remote _addr -   $remote _user [$time _local]  "$request"   $http _host '                         ' $status   $upstream _status  $body _bytes_sent  "$http _referer"   "                        ' $http _user_agent '   "$upstream _addr"   "$http _x_forwarded_for"   ';     #access_log   logs /access.log  main;    sendfile       on;     tcp_nopush     on;    keepalive_timeout   60;    server_tokens  off;    limit_rate_after  3m;   &nBsp;limit_rate 512k;     tcp_nodelay on;    client_ header_buffer_size 256k;    large_client_header_buffers 4 256k;      #Define  nginx proxy module        proxy_ http_version 1.1;        proxy_connect_timeout 5;         proxy_read_timeout 60;         proxy_send_timeout 5;        proxy_buffer_size    16k;        proxy_buffers     4  64k;        proxy_busy_buffers_size      128k;        proxy_temp_file_write_size  128k;        &Nbsp;proxy_headers_hash_max_size 51200;        proxy_headers_hash _bucket_size 6400;         #需要在http字段, setting nginx cache         proxy_temp_path /data/nginx/proxy_temp_path;         proxy_cache_path /data/nginx/proxy_cache_path levels=1:2 keys_ Zone=cache_one:50m inactive=20m max_size=30g;# define gzip compression module     gzip on;    gzip_vary on;    gzip_ min_length  1k;    gzip_buffers     4 16k;     gzip_http_version 1.0;    gzip_comp_level 2;     gzip_types       text/plain application/x-javascript text/ css application/xml;    # define realserver pool    upstream   tomcat_server {        ip_hash;         server 192.168.1.10:5678        max_fails=0   weight=2;        server 192.168.1.20:7890         max_fails=0  weight=1;   }     server {        listen        80;        server_name  beyond.com www.beyond.com ;

The Nginx cache is successful and can be viewed in the cache directory:

Second, static data access local, static data to local nginx processing. Dynamic data is delivered to the backend agent's Tomcat server for processing.

Location ~ .*\. (png|gif|jpg|jpeg|bmp|swf) $ {        root /data/node1/ webapps/root;   #反向代理图片服务器, where the static data is handed over to local processing.         expires 1d;                       #缓存一天          proxy_cache one;                  #引用定义的缓存模块名称         proxy_ cache_valid 200 1h;        #请求返回值为200的则缓存1小时          proxy_cache_valid 302 10m;      # The request returns a value of 301 302 cache for 10 minutes         proxy_cache_valid any 10s;        #其他任何返回值缓存10秒     &NBsp;   add_header x-via  $server _addr;   #定义这个header名为X-via  through variables $server_ Addr clearly describes which server to respond to  server_addr        add_header  x-cache-status  $upstream _cache_status, #明确说明是否命中   $upstream _cache_status for upstream modules          }  Dynamic Data to the back-end agent Tomcat, to achieve static and dynamic separation. Of course, as a CDN, that said, you can separate the static data into another domain name.         location ~ \. (do|jsp|php) $ {                 proxy_pass  http://tomcat_server;                 proxy_set_header Host  $host;                 proxy_set_header X-Real-IP         $remote _addr;                proxy_set_header x-forwarded-for  $proxy _add_x _forwarded_for;        }
