Apache - redirecting with a new domain

由 ∥☆過路亽．° 提交于 2019-12-25 01:40:01
问题 We've had our site running on (say) stuff.com for a while, with a load of sub-domains for different applications, red.stuff.com, blue.stuff.com and of course a load of content stuff.com/things/in/my/head We've recently purchased a new domain, awesome.com. Can we configure Apache to replace the 'stuff.com' in any request that turns up, with 'awesome.com' permanently? Would this method keep any search engine listings and existing links valid? Thanks 回答1: You can use Apache's rewrite engine. Add

Root domain is not working properly

由 偶尔善良 提交于 2019-12-25 01:36:26
问题 I setup Zerigo DNS addon at my Heroku app using Heroku instructions for adding a custom domain. It works fine when you open www.spotty.rs. I also added spotty.rs as a domain in Heroku panel, and added a REDIRECT record at Zerigo (redirection to www.spotty.rs). When I type spotty.rs in browser sometimes it redirects me to www.spotty.rs and sometimes I got Application error. In console, heroku log command displays H70 error which states that DNS records are not set correctly. Any idea why is

Pointing domain name to azure traffic manager URL instead of directly to server IP

由 梦想的初衷 提交于 2019-12-25 01:33:44
问题 So I have a domain badgag.com That points to an IP of the current server. But I want it instead to point to http://badgag.trafficmanager.net/ This DNS will route to the server with the lowest latency. So I try to change mapping to badgag.com -> badgag.trafficmanager.net -> closest web app -> IP But I am not sure what A, cname etc records I need to change. This is how it looks now: A @ 104.45.14.249 1 time CNAME autoconfig @ 1 time CNAME autoconfig.admin @ 1 time CNAME autodiscover @ 1 time

问题 I have no Internet access in my Android Emulator. The app I am developing needs Internet connection, but the Android Emulator have no internet connection. I also tried to use the native browser of the emulator, but it also does not work. When I export my app to a real android, it works just fine. I already tried to press F8 to turn on and off the "3G connection" in the emulator. I already turned off the Windows Firewall, but it didn't work. Data: Windows 7 x64 Eclipse Plugin for Android

由 余生颓废 提交于 2019-12-25 00:09:29
问题 We have a vpc in aws, it there some feature provided by aws to automatically add private DNS to route53 when manually launch an instance. 回答1: If you have installed boto, you can add / update DNS settings like this: DNS_ADDRESS="`ec2metadata | grep 'public-hostname:' | cut -d ' ' -f 2`" /usr/local/bin/route53 change_record <Hosted zone ID> foo.bar.com. CNAME $DNS_ADDRESS 300 DNS_ADDRESS is the AWS DNS name of the instance such as ec2-1-2-3-4.eu-west-1.compute.amazonaws.com The second line

Mobile website redirection based on user agent

由 耗尽温柔 提交于 2019-12-25 00:07:55
问题 Say I've got two distinct domains: 1) http://sub.test.org 2) http://m.sub.test.org for my website. I want domain n.1 to be associated to the full-version of my website (intended to be mainly visited by desktop user agents) and domain n.2 to be associated to its mobile-version (intended to be mainly visited by mobile user agents). Both of the versions reside on an external host which runs an instance of Apache webserver I can't control directly, but I am able to post .htaccess files and

How to create sub.domain for user opon sign up

由 坚强是说给别人听的谎言 提交于 2019-12-24 22:22:58
问题 I am using php/mysql on linux servers. I want to create a user sub domain for each user upon sign up. For instance, john doe --> johndoe.example.com The issue is, we are going to allow customizations such as adding custom features for clients wanting customizations. So, is it better we automate the process or manually create sub domains for clients requiring customizations and let other users just use basic login? And how can i automate the process if need be? 回答1: Instead of creating

$_SERVER[“SERVER_NAME”] not showing www.example.com

由 喜欢而已 提交于 2019-12-24 22:17:04
问题 Why does $_SERVER["SERVER_NAME"] not echo the www in www.example.com but it does work when I echo it from a sub domain like test.example.com ? 回答1: I don’t know why it doesn’t contain the expected value. But try $_SERVER['HTTP_HOST'] instead, that contains the value provided by the client in the HTTP header field Host. But see Chris Shiftlett’s SERVER_NAME Versus HTTP_HOST for security considerations. 来源： https://stackoverflow.com/questions/1481737/serverserver-name-not-showing-www-example

Why does web-component-tester time out in flight mode?

由 烈酒焚心 提交于 2019-12-24 22:13:57
问题 I've got a basic web-component-tester project which works fine when I'm online. If I switch to flight mode, it seems to fail to connect to Selenium, and instead gives a largely useless error message after about 60s delay: "Error: Unable to connect to selenium". Edit 2 : I've narrowed the problem down in the following question, but I'd still like to know how to avoid it with web-component-tester: Why does NodeJS request() fail on localhost in flight mode, but not 127.0.0.1? (Windows 10) Edit :

ubuntu下DNS原理及相关设置

由 百般思念 提交于 2019-12-24 21:46:23
1.DNS原理分析如下： 当 DNS 客户机需要查询程序中使用的名称时，它会查询本地DNS 服务器来解析该名称。客户机发送的每条查询消息都包括3条信息，以指定服务器应回答的问题。 ● 指定的 DNS 域名，表示为完全合格的域名 (FQDN) 。 ● 指定的查询类型，它可根据类型指定资源记录，或作为查询操作的专门类型。 ● DNS域名的指定类别。 对于DNS 服务器，它始终应指定为 Internet 类别。例如，指定的名称可以是计算机的完全合格的域名，如im.qq.com，并且指定的查询类型用于通过该名称搜索地址资源记录。 DNS 查询以各种不同的方式进行解析。客户机有时也可通过使用从以前查询获得的缓存信息就地应答查询。DNS 服务器可使用其自身的资源记录信息缓存来应答查询，也可代表请求客户机来查询或联系其他 DNS 服务器，以完全解析该名称，并随后将应答返回至客户机。这个过程称为递归。 另外，客户机自己也可尝试联系其他的 DNS 服务器来解析名称。如果客户机这么做，它会使用基于服务器应答的独立和附加的查询，该过程称作迭代，即DNS服务器之间的交互查询就是迭代查询。 DNS 查询的过程如下图所示。 s服务的工作过程 外 （1）操作系统会先检查自己本地的hosts文件是否有这个网址映射关系，如果有，就先调用这个IP地址映射，完成域名解析 。 （2）如果hosts里没有这个域名的映射
