大橙子网站建设,新征程启航
为企业提供网站建设、域名注册、服务器等服务
浏览器可以查看到页面元素,按 F12 查看页面元素内容,它默认定位在Network。如果不是在Network,就去选择下Network,然后刷新下网页,会看到如图
会看到右侧出现很多的元素,每一行都表示一个元素,这些请求,这些访问都会记录到访问日志里面去的,但实际上没有必须记录一些图片、css、js等元素,而这些请求都会记录到日志文件里,就会导致每天的日志访问量很大,对之后的运维很不方便,所以就有了需求,对于静态的元素的uri 不进行记录
排除图片、css、js等,拷贝配置文件到服务器里面
需要拷贝的配置文件[root@hf-01 ~]# vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf
[root@hf-01 ~]# curl -x127.0.0.1:80 111.com/asdasdsaf.jpg -I HTTP/1.1 404 Not Found Date: Thu, 21 Dec 2017 15:35:14 GMT Server: Apache/2.4.29 (Unix) PHP/7.1.6 Content-Type: text/html; charset=iso-8859-1 [root@hf-01 ~]# 在访问这样的请求,不管是404,还是200都会记录日志
