Nginx Turn on gzip compression (pictures, files, CSS)

1, VIM open nginx configuration file

Vim/usr/local/nginx/conf/nginx.conf

2, to find the following paragraph, to modify

gzip on;

Gzip_min_length 1k;

Gzip_buffers 4 16k;

#gzip_http_version 1.0;

Gzip_comp_level 2;

Gzip_types text/plain application/x-javascript text/css application/xml text/javascript image /jpeg image/gif image/png;

Gzip_vary off;

Gzip_disable "MSIE [1-6]\.";

3. Explain

Line 1th: Open gzip

Line 2nd: No compression critical value, greater than 1K compression, generally do not need to change

Line 3rd: Buffer, yes, well, no explanation, no change.

Line 4th: With the reverse agent, the end of the communication is http/1.0, there should be no need to see the needs of the popular science, I have this comment on the line, the default is http/1.1

Line 5th: Compression level, 1-10, the larger the number of compression, the longer the time, look at the mood casually change it

Line 6th: To compress the file type, the lack of what to fill what on the line, JavaScript has two ways to write, the best is written on it, there is always someone complaining JS file is not compressed, in fact, write a format on the line

Line 7th: With squid and other caching services, on the words will be added to the header "Vary:accept-encoding", I do not need this thing, I look at it against the situation to do it

Line 8th: IE6 is not very friendly to gzip, does not give it gzip

4.: Wq save exit, Reload Nginx

/usr/local/nginx/sbin/nginx-s Reload

Finally a file of less than 1K, because my threshold is 1K, so no compression
