Apache web page optimization

Overview of Optimization

Compression function optimization

Configure the web page compression function of Apache, which uses the gzip compression algorithm to compress the web page content and then transfer it to the client browser.

Want to see its compression function. Let's put a photo on the default web page and try [root@localhost abc] # cd / abc/ [root@localhost abc] # lsapr-1.6.2.tar.gz Discuz_X2.5_SC_UTF8.zip mysql-5.6.26.tar.gzapr-util-1.6.0.tar.gz fiddler.exe php-5.6.11.tar.bz2awstats-7.6.tar .gz httpd-2.4.29.tar.bz2 tu9892_14.jpg # this is our picture cronolog-1.6.2-14.el7.x86_64.rpm LAMP-php5.6.txt [root@localhost abc] # cp tu9892_14.jpg / usr/local/httpd/htdocs/ # copy this photo to the default home page [root@localhost abc] # cd / usr/local/httpd/htdocs/ [root@localhost htdocs] # Lsindex.html tu9892_ 14.jpg [root @ localhost htdocs] # vim index.htmlIt works!

Go to the client to test the compression function

Optimization of caching time of web pages

Configure Apache through the mod_expire module, make the web page cache in the client browser for a period of time, avoid repeated requests, reduce the access frequency and times of the client segment, and achieve the purpose of reducing unnecessary traffic and increasing access speed.

The previous steps are more compressed. Let's go directly to the main configuration file to open the cache module Listen 192.168.136.136 Listen 80 # enable the listening address # Listen 80 # turn off the IPV6 listening address ServerName www.kgc.com:80 # turn on the domain name server LoadModule expires_module modules/mod_expires.so # add ExpiresActive On # enable function ExpiresDefault "access plus 31104000 seconds" # Open caching time 31104000 0s verify syntax format There is no error [root@localhost conf] # cd / usr/local/httpd/ [root@localhost httpd] # cd bin/ [root@localhost bin] #. / apachectl-tSyntax OK enable the service to check whether the port has been provided [root@localhost bin] #. / apachectl start [root@localhost bin] # netstat-ntap | grep 80tcp 0 192.168.136.136min 80 0.0.0.0 * LISTEN 52832/httpd [root@localhost bin] # systemctl stop firewalld.service [root@localhost bin] # setenforce 0 check whether the cache module has been started [root@localhost bin] #. / apachectl-t-D DUMP_MODULES | grep "expires" expires_module (shared) go to the client segment to test it.
