How to enable gzip in centos apache

This article introduces how to enable gzip in centos apache. If you need it, refer to it.

The method for enabling gzip compression is simple. Connect to the server and open the configuration file "httpd. conf". Find the following two sentences and remove the previous "#"

The Code is as follows:	Copy code
LoadModule deflate_module modules/mod_deflate.so LoadModule headers_module modules/mod_headers.so

Add the following statement at the end of the configuration file:

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 .(? : Pdf | 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 enable File compression.

The last three sentences are the files that do not need to be compressed. jpg, gif, and png images are compressed. Then, gzip compression will increase the burden on the server.
