使用nginx的proxy_cache做网站缓存

文章源自网络

proxy模块中常用的指令时proxy_pass和proxy_cache.nginx的web缓存功能的主要是由proxy_cache、fastcgi_cache指令集和相关指令集完成，proxy_cache指令负责反向代理缓存后端服务器的静态内容，fastcgi_cache主要用来处理FastCGI动态进程缓存(这里我不是很清楚这两个指令的区别，好像功能上都差不多，尤其后面这句话的意思，是我翻译过来的)。确认proxy模块安装好后，下面对nginx的配置文件进行设置，重点部分如标红字体所示。这是我的nginx.conf配置文件。user www-data;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 {include mime.types;default_type application/octet-stream;log_format main '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for" "$host"';#access_log logs/access.log main;sendfile on;#tcp_nopush on;#keepalive_timeout 0;keepalive_timeout 65;#Compression Settingsgzip on;gzip_http_version 1.0;gzip_comp_level 2;gzip_proxied any;gzip_min_length 1100;gzip_buffers 16 8k;gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;# Some version of IE 6 don't handle compression well on some mime-types,# so just disable for themgzip_disable "MSIE [1-6].(?!.*SV1)";# Set a vary header so downstream proxies don't send cached gzipped# content to IE6gzip_vary on;#end gzip#cache beginproxy_buffering on;proxy_cache_valid any 10m;proxy_cache_path /data/cache levels=1:2 keys_zone=my-cache:8m max_size=1000m inactive=600m;proxy_temp_path /data/temp;proxy_buffer_size 4k;proxy_buffers 100 8k;#cache end## Basic reverse proxy server #### Apache (vm02) backend for www.example.com ##upstream apachephp {server www.quancha.cn:8080; #Apache1}## Start www.quancha.cn ##server {listen 80;server_name *.quancha.cn;access_log logs/quancha.access.log main;error_log logs/quancha.error.log;root html;index index.html index.htm index.php;## send request back to apache1 ##location / {proxy_pass http://apachephp;proxy_cache my-cache;proxy_cache_valid 200;#Proxy Settingsproxy_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;proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;proxy_max_temp_file_size 0;proxy_connect_timeout 90;proxy_send_timeout 90;proxy_read_timeout 90;proxy_buffer_size 4k;proxy_buffers 4 32k;proxy_busy_buffers_size 64k;proxy_temp_file_write_size 64k;##End Proxy Settings}}## End www.quancha.cn ##}
