11.22 The access log does not log static files (reduces the amount of memory that is not required to occupy storage space)

Access log does not record files of the specified type

网站大多数元素为静态文件，片、css、js等，这些元素可以不用记录把虚拟主机配置文件改成如下：<VirtualHost *:80>    DocumentRoot "/data/wwwroot/111.com"    ServerName 111.com    ServerAlias www.exampl.com 2111.com.cn    ErrorLog "logs/111.com-error_log"    SetEnvIf Request_URI ".*\.gif$" img    SetEnvIf Request_URI ".*\.jpg$" img    SetEnvIf Request_URI ".*\.png$" img    SetEnvIf Request_URI ".*\.bmp$" img    SetEnvIf Request_URI ".*\.swf$" img    SetEnvIf Request_URI ".*\.js$" img    SetEnvIf Request_URI ".*\.css$" img    CustomLog "logs/111.com-access_log" combined env=!img</VirtualHost>重新加载配置文件 -t , gracefulmkdir /data/wwwroot/www.123.com/images   //创建目录，并在这目录下上传一个图片curl -x127.0.0.1:80 -I 111.com/images/123.jpgtail /usr/local/apache2.4/logs/111.com-access_log

11.24 static element Expiration time

浏览器访问网站的图片时会把静态的文件缓存在本地电脑里，这样下次再访问时就不用去远程下载了增加配置，ExpiresActive on 打开功能开关

Vim/usr/local/apache2.4/conf/extra/httpd-vhosts.conf

<IfModule mod_expires.c>    ExpiresActive on    ExpiresByType image/gif "access plus 1 days"    ExpiresByType image/jpeg "access plus 24 hours"    ExpiresByType image/png "access plus 24 hours"    ExpiresByType text/css "now plus 2 hours"    ExpiresByType application/x-javascript "now plus 2 hours"    ExpiresByType application/javascript "now plus 2 hours"    ExpiresByType application/x-shockwave-flash "now plus 2 hours"    ExpiresDefault "now plus 0 min" </IfModule>需要打开 expires_module 模块vim /usr/local/apache2.4/conf/httpd.confcurl 测试，看cache-control:max-age
