Nginx to set static page compression and cache expiration Time _nginx

Friends using the Nginx server may be aware of the need to set the HTML static page cache with page compression and expiration time settings, I would like to introduce to you the configuration method, including the Ico,gif,bmp,jpg,jpeg,swf,js,css, MP3 files are cached locally.

The server's bandwidth overhead can be reduced by nginx the static resources on the server and compressing the resources.

The following is how Nginx sets the static resource expiration time:

    Location ~*. (Ico|gif|bmp|jpg|jpeg|png|swf|js|css|mp3) {
      root  /var/www/opkeep;
      Expires 30d;
    }

The above configuration can cache the Ico,gif,bmp,jpg,jpeg,swf,js,css,mp3 files locally, without having to retrieve them again from the server every time you access them.

The compressed configuration is as follows:

    gzip on;
    Gzip_min_length 1000;
    Gzip_buffers   4 8k;
    Gzip_types    text/plain application/x-javascript text/css;

For text, JS and CSS file compression, under normal circumstances, compressed size is the original size of 25%, or even smaller.

Cache dynamic pages, cache expiration time

This is configured with a virtual machine:

Nginx Configuration file content:

This sentence is mainly:

Proxy_cache_path/www/levels=1:2 keys_zone=z:10m inactive=1m max_size=30g;

This sentence defines an area, the name is Z, in the memory space is 10MB, the maximum space in the hard disk is 30G;

Inactive=1m is, after 1 minutes cache failure, request from the source server from the new
Right here, inactive=1m. If the cache is not accessed for 1 minutes, Nginx deletes the cache.

HTML files can be cached and then go to a lot of places to ask
