Nginx Server Cache Settings Instance explanation

Use Nginx as the Web cache, located between the content source Web server and the client.

Solution for Web caching:

1 Squid Cache

2 Nginx Proxy_cache.

Let's see, Nginx's Proxy_cache.

Composition: Proxy_cache related instruction set, fastcgi related instruction set

Proxy_cache which buffer will be used

Proxy_cache_path Cache file Storage Path

Proxy_cache_methods which HTTP methods are cached

Minimum number of Proxy_cache_min_users cache usage

Proxy_cache_valid sets different cache times for URLs with different return status codes

Proxy_cache_key sets cache key value, Nginx hash cache based on key value

Install a third party Ngx_cache_purge module:

Deletes the specified URL cache

Nginx Web Caching Service

Step One:

Ulimit-shn 65535

Install Pcre./configure && make && make install

Install Ngx_cache_purge as long as the decompression is OK

Installation

code example:

Nginx./configure--user=www--group=www--add-module=. /ngx_cache_purge

--prefix=/usr/local/nginx--with-http_stub_status_module--with-http_ssl_model

&& make && make install

Step Two:

Create 2 Cache Directories

code example:

Mkdir-p/data0/proxy_temp_path

Mkdir-p/data0/proxy_cache_path

Step Three:

Configuring the nginx.conf Cache

code example:

http{

...

Proxy_temp_path ...;

Proxy_cache_path ...;

server{

...

Proxy_cache Cache_name;

Proxy_cache_valid ...;

Proxy_cache_key ...;

}

}

For the Nginx cache configuration, here are several articles recommended, you can also refer to the following:

Nginx Cache Configuration Instance

Nginx set the static file cache time

Nginx cache local static files

Nginx Five kinds of caching methods

Nginx methods for caching static files

Nginx Proxy_cache Cache Configuration

Nginx front-end proxy, caching

Next, 谫, fastcgi cache configuration.

Parameter description:

Which buffer is used by the Fastcgi_cache cache

Fastcgi_cache_path set the path to store cached files

Fastcgi_cache_methodes sets which HTTP methods are cached, the default HTTP Get/head method

Fastcgi_cache_min_users sets the minimum number of times to use the cache, default 1

Fastcgi_cache_valid sets different cache times for URLs that return different status codes

Fastcgi_cache_key sets the key value of the Web cache, Nginx the hash storage cache based on the key value MD5

Step One:

Create cache directory: Cache path must be on the same disk partition

code example:

Mkdir-p/data0/fastcgi_temp_path

Mkdir-p/data0/fastcgi_cache_path

Step Two:

code example:

Nginx configuration file

http{

...

Fastcgi_temp_path ...;

Fastcgi_cache_path ...;

server{

...

Fastcgi_cache Cache_name;

Fastcgi_cache_valid ...;

Fastcgi_cache_key ...;

}

}
