问题 I'm trying to run a squid server behind nginx. I configured nginx like this: server { listen 8080; location / { proxy_pass http://localhost:3128; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; } } Then I set my http network proxy to: my-nginx-server-address:8080 So when I try to view the Google homepage, the nginx will get the request: Get http://www.google.com/ HTTP/1.1 However when nginx pass the request to squid it will change the request_uri to / So squid won't work

问题 I've got a python web crawler and I want to distribute the download requests among many different proxy servers, probably running squid (though I'm open to alternatives). For example, it could work in a round-robin fashion, where request1 goes to proxy1, request2 to proxy2, and eventually looping back around. Any idea how to set this up? To make it harder, I'd also like to be able to dynamically change the list of available proxies, bring some down, and add others. If it matters, IP addresses

Squid代理服务器综合应用案例

squid代理服务器 squid是一种用来缓存Internet数据的软件。接受来自客户机需要下载的目标的请求并适当的处理这些请求。也就是说,如果一个客户端想要打开默认网站,它请求squid为它取得这个页面。squid随之连接到远程服务器并向这个页面发出请求。然后,squid显式地聚集数据到客户端机器,而且同时复制一份。当下一次有人需要同一页面时,squid可以简单的从磁盘中读到它,那样数据会立即传输到客户机上。 squid代理的作用 - 通过缓存方式为用户提供Web加速访问 - 对用户的Web访问请求进行过滤控制 squid的几种代理模式 1. 正向代理模式 1)标准正向代理模式 2)透明正向代理模式 主要作用: 实现代理上网、隐藏用的真实访问信息以及对控制用户访问网站行为的访问控制列表(ACL)进行限制。 2. 反向代理模式 主要作用: 加快用户访问网站的速度,降低网站资源服务器的负载压力。 标准正向代理模式与透明正向代理模式的区别: 用户是否需要配置代理服务器的信息。若使用透明代理模式,则用户感知不到代理服务器的存在。 正向代理与反向代理的区别: 1. 概念 正向代理: 对于原始服务器而言,就是客户端的代言人 反向代理: 对于客户端而言,就像是原始服务器 2. 用途 1.正向代理的典型用途是为在防火墙内的局域网客户端提供访问Internet的途径

Apache HTTP Server(简称Apache)是Apache软件基金会的一个开放源码的网页服务器,可以在大多数计算机操作系统中运行,由于其多平台和安全性被广泛使用,是最流行的Web服务器端软件之一。它快速、可靠并且可通过简单的API扩展,将Perl/Python等解释器编译到服务器中。 yum install httpd -y systemctl start httpd systemctl stop firewalld systemctl enable httpd systemctl disable firewalld apache的基本配置 index.html apache的默认发布文件 /etc/httpd/conf/httpd.conf /etc/httpd/conf.d/*.conf apache的配置文件 /var/www/html apache的默认发布目录 80 apache的默认端口 根据这些默认设置,我们可以先试验一下: [root @localhost html]# echo "<h1 style="c olo r":limegreen>FirstHtml</h1>" >> index.html [root @localhost html]# pwd /var/www/html 效果如图: 1.修改默认发布文件 [root @localhost

Thanks :) Make your crawler have a list of proxies and with each HTTP

做一个合格的Linux运维工程师

做为一个运维工程师,你必须掌握最基本的技能方能胜任这份工作,否则,是没有公司愿意接纳你,并继续培养你。 独立安装系统与软件 在安装系统时你更会去留心学习 Linux 的目录结构和作用,学会系统的安装方法和软件安装方式,对目录与文件的操作,呃,这些够基础吗? 2. 选择一本适合自己的书籍 学习Linux除了网上免费的视频教程之外,还是要多看书,多理解、思考,将你不会、不懂的做好笔记,好记性不如烂笔头。选择一本适合自己的书籍,有人说 《Linux就该这么学》 太扯、内容太简单,而我看着这本书却非常适合我自己,自己看其它书籍感觉看不懂,就扔那里不在愿意去看,适合自己的就是最好的书,只有入门了才能更好的往下面学习,合格的工程师更要学会自学。 3. 管理用户 Linux是一个多用户、多任务的操作系统,允许许多用户同时使用这个机器处理多个任务,必须管理好这些用户,即使初学Linux的小白也知道,可以通过网络让多人同时登录,而非使用机器上仅有的一个显示器、一个键盘和鼠标。比如 web服务器,是不是多用户?ftp服务器也是多用户。系统上可以开启远程登录ssh 或者telnet,这样几个人同时登录到该Linux系统上面。而需要管理好每个服务后面的帐号(用户), 可以安全、合理使用Linux系统资源。 4. 磁盘的合理管理 做了运维才知道磁盘不是最值钱,而数据才是无价的。往往磁盘的空间是有大小的
