Apache Tuning Open Deflate Compression module

enable the Apache deflate module to turn on compression and reduce bandwidth when the website is transmitted.

Apache needs to compile the installation mode, to/usr/local/apache for the Apache installation directory, the source package/usr/local/src/httpd-2.4.33 as an example

First View/usr/local/apache/bin/apachectl-m # # #查看里面的模块是否有deflate模块, you can also filter/usr/local/apache/bin/apachectl-m | grep deflate

If there is a httpd.conf under the open, if not shown, or with grep filtered after the display syntax OK, the module is not installed.

Compile and install the Deflate module in Dynamic shared module mode (DSO)

/usr/local/apache/bin/apxs-c-i-a/usr/local/src/httpd-2.4.33/modules/filters/mod_deflate.c #其中前面部分是安装好的apache软件里面的apxs程序, behind the deflate compression module in Apache's Source installation package

APXS Program Compilation options:

-C means to perform a compile module operation

-I means performing the install module operation

-a means to automatically add a loadmodule line to the httpd.conf file to activate the module

When the installation is complete, see if the module is installed and activated in vi/usr/local/apache/conf/httpd.conf

LoadModule Deflate_module modules/mod_deflate.so
