Nginx Web Cache Configuration __web

Turn from: http://ttcool.blog.51cto.com/1186572/1302866

1. Scenario: Use Proxy_cache to cache Web static content files and HTML full-page caching via rewrite pseudo static.

Dynamic content is dynamically acquired through Ajax, and content consistency is maintained.

2.nginx Configuration

A. Add cache file Save path

Vi/etc/nginx/nginx.conf

#注: The paths specified by Proxy_temp_path and Proxy_cache_path must be in the same partition
Proxy_temp_path/cache/proxy_temp_path;

#设置Web缓存区名称为cache_one, the memory cache space size is 200mb,1 Day has not been accessed automatically clear, hard disk cache space size of 30GB.

Proxy_cache_path/cach/proxy_cache_path levels=1:2 keys_zone=cache_one:200m inactive=5m max_size=30g;

B. Adding a cache configuration

Location ~. *\. (gif|jpg|jpeg|png|bmp|swf|js|css|html) $

{

#如果后端的服务器返回502, 504, execution timeout, and so on, automatically forwards the request to another server in the upstream load balancing pool to implement failover.
Proxy_next_upstream http_502 http_504 error timeout invalid_header;

Proxy_cache Cache_one;
#进行缓存, using Web cache Cache_one

Proxy_cache_valid 304 5m;
#对不同的HTTP状态码设置不同的缓存时间

Proxy_cache_valid 302 1m;
Proxy_cache_valid any 1m;
Proxy_cache_key $host $uri$is_args$args;
#以域名, URI, and parameters are combined into the Web cache key value, nginx the cache content to the level two cache directory according to the key value hash
Proxy_set_header Host $host;
Proxy_set_header X-real-ip $remote _addr;
Proxy_set_header x-forwarded-for $remote _addr;
Proxy_set_header accept-encoding "None";
#设定proxy_set_header accept-encoding '; (or the backend server shuts down gzip), so that the machine will not cache the compressed files, causing garbled
#proxy_set_header accept-encoding ""; This can also be

Proxy_ignore_headers "Cache-control" "Expires";
#这段配置加上后, Proxy_cache can support background-setting expires.


if (!-e $request _filename)

{
Proxy_pass http://emulsites;
}

Expires 30m;

}

#php文件请求转发给后端
Location ~. *\. (php|cgi)? $
{
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_pass http://emulsites;
}

3. Heavy Duty Nginx

sudo service Nginx Reload

Access the page to see if the cache directory generates a cached file
