#识别ID
id: test

启动客户端：

/etc/init.d/salt-minion  start

服务器端确认：

salt-key -A

执行模块命令：

salt '*' test.ping

执行shell命令：

rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

CentOS5:

rpm -ivh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-5.rpm

CentOS7：

rpm -ivh http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

安装后源默认禁用，如需启用可修改remi.repo或：

yum --enablerepo=remi-php55 install php

PHP HTML解析类

发布时间：January 21, 2014 // 分类：PHP // No Comments

1.phpQuery

<?php
   require("phpQuery-onefile.php");
   phpQuery::newDocumentFile('https://www.haiyun.me/archives.html'); 

   //foreach (pq('body .main li')->find('a') as $a) {
   foreach (pq('body .main li a') as $a) {
      $hrefs[] = pq($a)->attr('href');
      $hrefs[] = pq($a)->text();
   }
   print_r($hrefs);
?>

记得释放内存：

phpQuery::$documents = array();
phpQuery::unloadDocuments();

2.基于tidy的HtmlParserModel，可解析不正规的HTML页面：

yum install php-tidy
git clone https://github.com/bupt1987/HtmlParserModel.git

<?php
   include_once "HtmlParserModel.php";
   $html = file_get_contents('http://www.amazon.com/s/node=3564986011');
   $html_dom = new HtmlParserModel($html);
   $p_array = $html_dom->find('a.title');
   foreach ($p_array as $p){
      echo $p->getPlainText();
   }
?>

Nginx Proxy细节问题

发布时间：January 18, 2014 // 分类：Nginx // No Comments

1.rewrite使用break结，使用last会对server标签重新发起请求

location /a/ {
    rewrite ^/a/(.*)$ /b/$1 break;
    proxy_pass https://www.haiyun.me;
}

2.proxy_pass结尾添加/会丢弃路径目录，如下访问/a/test.html会代理到/test.html

location /a/ {
    rewrite ^/a/(.*)$ /b/$1 break;
    proxy_pass https://www.haiyun.me/;
}

3.代理访问重定向的网址：

proxy_redirect https://www.haiyun.me/ http://$host/;
