Linux CentOS Apache to open gzip method

The way to turn on gzip compression is simple, connect the server and open the configuration file "httpd.conf", find the following two sentences, remove the "#" in front

The code is as follows	Copy Code
LoadModule Deflate_module modules/mod_deflate.so LoadModule Headers_module modules/mod_headers.so

At the end of the configuration file, add the following statement:

The code is as follows

Copy Code

<ifmodule deflate_module> Setoutputfilter DEFLATE Setenvifnocase Request_uri. (?: gif|jpe?g|png) $ no-gzip dont-vary Setenvifnocase Request_uri. (?: Exe|t?gz|zip|bz2|sit|rar) $ no-gzip dont-vary Setenvifnocase Request_uri. (?:p df|doc|avi|mov|mp3|rm) $ no-gzip dont-vary Addoutputfilterbytype DEFLATE text/html text/plain text/xml text/css Addoutputfilterbytype DEFLATE Application/x-javascript </IfModule>

The first sentence is to turn on file compression

The third sentence is to set the file without compression, JPG, GIF, PNG image is already compressed, and then use gzip compression will increase the burden on the server, can not get stuck
