安装部署 Tomcat服务器 案例 1 ：安装部署 Tomcat 服务器 案例 2 ：使用 Tomcat 部署虚拟主机 案例 3 ：使用 Varnish 加速 Web 1 案例 1 ：安装部署 Tomcat 服务器 1.1 问题 本案例要求部署 Tomcat 服务器，具体要求如下： 安装部署 JDK 基础环境 安装部署 Tomcat 服务器 创建 JSP 测试页面，文件名为 test.jsp ，显示服务器当前时间 然后客户机访问此 Web 服务器验证效果： 使用火狐浏览器访问 Tomcat 服务器的 8080 端口，浏览默认首页 使用火狐浏览器访问 Tomcat 服务器的 8080 端口，浏览默认测试页面 1.2 方案 使用 2 台 RHEL7 虚拟机，其中一台作为 Tomcat 服务器（ 192.168.2.100 ）、另外一台作为测试用的 Linux 客户机（ 192.168.2.5 ），如图 -1 所示。 图 -1 使用 RPM 安装 JDK 基础环境 使用源码安装部署 Tomcat 服务器 1.3 步骤 实现此案例需要按照如下步骤进行。 步 骤一：部署 Tomcat 服务器软件 (192.168.2.100/24) 1 ）使用 RPM 安装 JDK 环境 [root@web1~]#yum -y install java-1.8.0-openjdk// 安装 JDK

Im trying to use esi to make a ninja caching on my site. The idea is, the site is mostly static, I just need to do fancy stuff if the user is logged in or not. So I was trying to put an on the page A, and set triggers in the application at page B. This way I could cache the page A on varnish, and let the server deal with the small work that is page B. But the cookies I've seted on page B were not forwarded to headers of page A and didn't work =/ Is this that Im trying to do possible? I could use ajax, but doing this inside the server, before sending the page to the user seems more correct to

一、Varnish 安装前的准备 Varnish 安装环境的准备： 主机名：Varnish 操作系统：CentOS Linux release 7.6.1810 (Core) IP地址：192.168.1.194 二、Varnish 安装前的介绍 Varnish 是一个开源软件，可以选择安全二进制包，或者从源码定制编译安装。 在相关操作系统上，可以使用系统自带的包管理器来安装，常见的用例： FreeBSD： varnish 5.x 以前的安装方式： 源码安装：cd /usr/ports/varnish && make install clean 二进制包安装： pkg_add -r varnish varnish 5.x 以后的安装方式： 源码安装：cd /usr/ports/www/varnish4 && make install clean 二进制包安装： pkg_add -r varnish4 CentOS/RedHat： # 编译安装时，所需安装的依赖包： yum install autoconf automake jemalloc-devel libedit-devel libtool ncurses-devel pcre-devel pkgconfig python-docutils python-sphinx Debian/Ubuntu： Varnish 已经发布了

Storage backends 存储后端 Intro varnish拥有可插入式的存储后端，它可以存储数据在在各种不同表现特性的后端中。默认的配置就是使用限制了大小的malloc后端（基于内存的）。对于一些vanish部署方式，你可能需要调整储存设置来适合相应的部署方式。 malloc syntax: malloc[,size] malloc是基于内存的后端。每个对象都将从内存中分配资源来存储。如果你的系统运行内存较小，swap将会被使用。 请注意，该尺寸限制只限制了实际存储，同时使用各种内部机制使得每个对象在内存中大约占1k，这种情况也包括在真实的存储中。 size参数指定最大分配给vanishd的内存数量。size的假定单位是byte，除非你指定下面的一个后缀： K, k The size is expressed in kibibytes. M, m The size is expressed in mebibytes. G, g The size is expressed in gibibytes. T, t The size is expressed in tebibytes. 默认size是不限制的 malloc的性能依赖于内存速度，所以很快。如果数据集大于可用内存，malloc的性能将依赖操作系统的实际分页能力。 file syntax: file[,path[

I'm very lost on this problem, and I don't know where could be the problem, so, I hope that you could help me. I have an HTTP BASIC authentification with symfony, and I'm trying to reach an url which is protected by this auth, with an tag in a Drupal page. Every requests are send to a Varnish I give username and password in the url like that : <esi:include src="http://admin:adminpass@api.dev:8081/app.php/next"/> In my varnish configuration file, I have only that lines for auth.http: if (req.http.Authorization) { return (pass); } My backend for Symfony is working well without http

CLI-bossing Varnish around CLI 向Vanish下发指令 一旦vanish启动，你可以使用命令行接口来控制它。 最轻松的使用CLI的方法是在运行varnishd的机器上运行，varnishadm varnishadm help 如果你想远程使用varnishadm，有两种方法。 你可以使用ssh登录到运行varnishd的机器上然后varnishadm ssh $http_front_end varnishadm help 同时你也可以配置vanishd接受远程的CLI连接，（使用-T和-S参数） varnishd -T :6082 -S /etc/varnish_secret 然后在远程主机上运行vanishadm，像这样 varnishadm -T $http_front_end -S /etc/copy_of_varnish_secret help 但是你也看到，ssh是更方便的。 如果运行vanishadm没有添加参数，它将会从标准输入读取CLI命令，如果你指定了参数，它将这些参数作为单个CLI命令来执行。 CLI总是返回一个状态码，告诉你操作的结果，'200'为成功，其他状态码就有问题了。 vanishadm退出时使用状态1，并且如果不是200的状态码，它将在标准错误输出中打印状态码。 What can you do with the CLI

I'm trying to set up Xdebug remote debugging to a site sitting behind Varnish as a caching layer using PHPStorm. Varnish is sitting as a frontend on port 80 with Apache talking to it as a backend on port 8080. If I bypass Varnish and talk directly to the site on port 8080 Xdebug and Phpstorm work as expected, however then I'm not really testing the system properly - what I really need to do is trigger a debug session even when the request is proxied through Varnish. Obviously I'm not expecting cached content to trigger a debug session, but uncached content still should. My Xdebug settings are

I have a Rails app that is running on port 8080 that I need to trick to think it's running on port 80. I am running Varnish on port 80 and forwarding requests to nginx on port 8080 , but when the user tries to login with OmniAuth and the Devise gem generates a url to redirect back to the server, it thinks its on port 8080 which then the user will see. Is there any way to trick the Rails app to hard code the port as 80 (I would think it's a bad practice), or have nginx forward the request as if it's running on port 80? Since I am not running a nginx proxy to the Rails app I can't think of a way
