篇首语：不塞不流，不止不行。本文由小常识网(cha138.com)小编为大家整理，主要介绍了知识大全 nginx利用proxy相关的知识，希望对你有一定的参考价值。

nginx利用proxy_cache来缓存文件有需要的朋友可参考代码如下复制代码

user zhangy users;worker_processes ;error_log /var/vlogs/nginx_error log crit;pid /var/vlogs/nginx pid;#Specifies the value for maximum file descriptors that can be opened by this process worker_rlimit_nofile ;events use epoll; worker_connections ; include mime types; default_type application/octet stream; #charset gb ; server_names_hash_bucket_size ; client_header_buffer_size k; large_client_header_buffers k; client_max_body_size m; sendfile on; tcp_nopush on; keepalive_timeout ;

tcp_nodelay on;

fastcgi_connect_timeout ; fastcgi_send_timeout ; fastcgi_read_timeout ; fastcgi_buffer_size k; fastcgi_buffers k; fastcgi_busy_buffers_size k; fastcgi_temp_file_write_size k;//============ client_body_buffer_size k; proxy_connect_timeout ; proxy_read_timeout ; proxy_send_timeout ; proxy_buffer_size k; proxy_buffers k; proxy_busy_buffers_size k; proxy_temp_file_write_size k; proxy_temp_path /usr/local/nginx/proxy_temp;/*levels设置目录层次keys_zone设置缓存名字和共享内存大小inactive在指定时间内没人访问则被删除在这里是天max_size最大缓存空间*/proxy_cache_path /usr/local/nginx/proxy_cache levels= : keys_zone=content: m inactive= d max_size= m;//============等号中间要加的关键只要加上proxy_cache_path

gzip on; gzip_min_length k; gzip_buffers k; gzip_; gzip_p_level ; gzip_types text/plain application/x javascript text/css application/xml; gzip_vary on;

upstream myselfxtajmd server : ; server : weight= ;

server listen ; server_name localhost; index inde index php; log_format access $remote_addr $remote_user [$time_local] "$request" $status $body_bytes_sent "$_referer" "$_user_agent" $_x_forwarded_for ; access_log /var/log/test log access;

location / proxy_cache content; //根keys_zone后的内容对应 proxy_cache_valid d; //哪些状态缓存多长时间 proxy_cache_valid any d; //其他的缓存多长时间 proxy_cache_key $host$uri$is_args$args; //通过key来hash 定义KEY的值

proxy_pass //myselfxtajmd; 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;

//动态的放过 location ~ * (php|jsp|cgi)?$ proxy_set_header Host $host; proxy_set_header X Forwarded For $remote_addr; proxy_pass //myselfxtajmd;

上面只是配置的部分内容反向代理的那部分没有放进去了参考linux下nginx反向代理实现负载均衡当我们浏览时在代理端就把图片缓存了不用到代理终端去缓存了可以节省资源缓存的内容放在你设置的proxy_cache_path路径下面看下图
