171221---LAMP Apache访问日志

访问日志不记录指定类型的文件

• 网站大多元素为静态文件，如图片，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/www.111.com ServerName www.111.com ServerAlias 111.com 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，graceful
• mkdir /data/wwwroot/www.111.com/images #创建目录，并在这目录下上传一个图片
• curl -x 127.0.0.1:80 -I 111.com/images/111.jpg
• tail /usr/local/apache2.4/logs/111.com_access_log

[root@node35 ~]# vi /usr/local/apache2.4/conf/extra/httpd-vhosts.conf

    ErrorLog "logs/111.com-error_log"

访问日志切割

• 日志一直记录总有一天会把整个磁盘占满，所以有必要设置自动切割，并删除旧的日志文件
• 把虚拟主机配置文件改成如下： <VirtualHost :80> DocumentRoot "/data/wwwroot/www.111.com" ServerName www.111.com ServerAlias 111.com 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 "|/usr/local/apache2.4/bin/rotatelogs -l logs/111.com-access_%Y%m%d.log 86400" combined env=!img </VirtualHost>
• 重新加载配置文件-t，graceful
• ls /usr/local/apache2.4/logs

[root@node35 111.com]# vi /usr/local/apache2.4/conf/extra/httpd-vhosts.conf
    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

配置静态元素过期时间

• 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
• 增加配置 <IfMondule mod_expires.c> ExpiresActive on #打开该功能的开关 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 hour" ExpiresByType application/x-javascript "now plus 2 hours" ExpiresByType application/javascript "now plus 2 hours" ExpiresByType application/x-shockwave-flash "now plus 2 hours" ExpiresByType "now plus 0 min" </IfModule>
• 需要expires module
• curl测试，看cache-control:max-age

[root@node35 111.com]# vi /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 hour"
   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"
