Apache Web optimization----compression, caching

Lab Environment:

Required Packages: apr-util-1.4.1.tar.gz, httpd-2.4.2.tar.gz, apr-1.4.6.tar.gz

The host shared folder has been hung under/ABC

Experimental steps:

First, manually compile and install Apache

--------------------Install the package---------------------

Cd/abc
Yum Remove httpd–y????? Uninstalling the default installed HTTPD service
Tar zxvf apr-1.4.6.tar.gz-c/opt
Tar zxvf apr-util-1.4.1.tar.gz-c/opt
Tar zxvf httpd-2.4.2.tar.gz-c/opt

Cd/opt
Cp-r APR-1.4.6/HTTPD-2.4.2/SRCLIB/APR
Cp-r Apr-util-1.4.1/httpd-2.4.2/srclib/apr-util

------------------------Install the compilation environment---------------------
Yum install gcc gcc-c++ pcre pcre-devel zlib-devel–y

--------------------manually configure the installation-------------------

Cd/opt/httpd-2.4.2/
./configure \
--PREFIX=/USR/LOCAL/HTTPD \?????????????????? Specify the profile path
--enable-deflate \???????????????????????????????? Turn on the compression function
--enable-expires \??????????????????????????????? Turn on the cache function
--ENABLE-SO \???????????????????????????????????????? Enable dynamic module loading
--enable-rewrite \??????????????????????????????? Enable override feature
--enable-charset-lite \??????????????????????? Enable Character Set support
--enable-cgi????????????????????????????????????????? Enable CGI scripting support

Make && make install

------------------------------Set the startup script---------------
Grep-v "#"/usr/local/httpd/bin/apachectl >/ETC/INIT.D/HTTPD? Startup scripts

Vim/etc/init.d/httpd

? #!/bin/sh
????? # chkconfig:2345 85 15
????? # Description:apache is a world Wide Web server.

chmod +x/etc/init.d/httpd
Chkconfig--add httpd
Chkconfig--list httpd
Chkconfig--level httpd on

----------------------------establish a soft connection for easy management--------------------
Ln-s/usr/local/httpd/conf/httpd.conf/etc/httpd.conf?? Establish a soft connection for easy management
Vim/etc/httpd.conf

? Listen 192.168.100.20:80
?? #Listen 80

? ServerName www.benet.com:80

Setenforce 0
Service Iptables Stop
Cd/usr/local/httpd/bin
./apachectl-t?? Check syntax for problems

?????? ? Syntax OK??? Show no exception
Service httpd Start
Netstat-ntap | grep 80

Second, turn on the transmission compression function
Vim/etc/httpd.conf
LoadModule deflate_module modules/mod_deflate.so? Turn on the compression function
LoadModule headers_module modules/mod_headers.so? Turn on the head
LoadModule filter_module modules/mod_filter.so? Turn on the filter
<ifmodule mod_deflate.c>
??? Addoutputfilterbytype DEFLATE text/html text/plain text/css text/xml text/javascript?? File types that support compression
??? Deflatecompressionlevel 9??? Compression ratio
??? Setoutputfilter DEFLATE??? Supported Compression module modes
??? </IfModule>
./apachectl-t
Service httpd Restart
./apachectl-t-D dump_modules | grep "Deflate"?? Check that the module is turned on

Third, open the cache to more

Vim/etc/httpd.conf

? LoadModule Expires_module modules/mod_expires.so??? Turn on the cache module

<ifmodule mod_expires.c>
?? Expiresactive on
?? ExpiresDefault "Access plus seconds"???????????? Cache time 50s
? </IfModule>
