PHP统计nginx访问日志中的搜索引擎抓取404链接页面路径
我在服务器上有每天切割nginx日志的习惯,所以针对每天各大搜索引擎来访,总能记录一些404页面信息,传统上我只是偶尔分析下日志,但是对于很多日志信息的朋友,人工来筛选可能不是一件容易的事情,这不我个人自己慢慢研究了一点点,针对谷歌、百度、搜搜、360搜索、宜搜、搜狗、必应等搜索引擎的404访问生成为一个txt文本文件,直接上代码test.php。
复制代码 代码如下:
//访问test.php?s=google
$domain='http://www.jb51.net';
$spiders=array('baidu'=>'Baiduspider','360'=>'360Spider',
'google'=>'Googlebot','soso'=>'Sosospider','sogou'=>
'Sogou web spider','easou'=>'EasouSpider','bing'=>'bingbot');
$path='/home/nginx/logs/'.date('Y/m/').(date('d')-1).'/access_www.txt';
$s=$_GET['s'];
if(!array_key_exists($s,$spiders)) die();
$spider=$spiders[$s];
$file=$s.'_'.date('ym').(date('d')-1).'.txt';
if(!file_exists($file)){
$in=file_get_contents($path);
$pattern='/GET (.*) HTTP\/1.1" 404.*'.$spider.'/';
preg_match_all ( $pattern , $in , $matches );
$out='';
foreach($matches[1] as $k=>$v){
$out.=$domain.$v."\r\n";
}
file_put_contents($file,$out);
}
$url=$domain.'/silian/'.$file;
echo $url;
好就这样了。没有什么高深的技术,只有动手写的过程。
