1、首先在xyc.pp.ru的dns中将其cname到xya.in上；

2、编辑网站根目录下.htaccess文件，添加如下内容：

RewriteEngine on

#让xyc.pp.ru 访问xya.in目录xya.in网站

RewriteCond %{HTTP_HOST} ^xyc.pp.ru$
RewriteCond %{REQUEST_URI} !^/xya.in/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /xya.in/$1
RewriteCond %{HTTP_HOST} ^xyc.pp.ru$
RewriteRule ^(/)?$ xya.in/index.php [L]

保存即可将xyc.pp.ru指向xya.in子网站（xya.in子网站的子目录名为：xya.in）。

由于我的xya.in网站为wordpress博客，若仅进行如上设置还不能很好的支持多域名访问该网站，此时需要在WordPress后台增加PS WP Multi Domain插件并启用即可正常使用xya.in和xyc.pp.ru同时访问该网站！

方法一：删除A记录法（该方法适用于A记录较少的朋友）
      登录域名管理面板，删除该域名下所有的A记录，过几小时后再到CP中增加域名即可
小提示：有些DNS提供商有备份A记录的功能，大家可以先备份，当域名绑定成功后再恢复。

方法二：DNS跳板法（该方法支持DNS中转的DNS提供商，例如zoneedit和value-domain）。这里以zoneedit的设置方法为例。
    1、获得CP提供的DNS地址的IP，记录下来。
    2、在zoneedit里，选定这个RU域名，一次点击Advanced—>Make this Zone a Slave/Secondary，在Master DNS IP输入前面获得的DNS的IP地址，再点击Change Master IP—>YES。现在DNS已经移交CP空间的DNS管理了。
小提示：若要恢复zoneedit对改域名的解析功能，点击Free Slave Zone即可。

现在就让Domain Mirror来帮您实现这一梦想吧。

下面是其作者页面的详细说明（英文的！我将在近期以最简单的方式来加以说明！）

（简单地说就是已经支持2.7版了，首先是下载插件安装，启用，然后在设置菜单中找到Domain Mirror项，按提示依次输入您想停靠的域名，标题、小标题、博客显示url（填两次），最后，最重要的也就是你必须将这些域名停靠在购买空间的主域名上－－在DreamHost空间是通过mirror项来解决！）－－祝您好运！

WordPress 2.7: Works.
WordPress 2.6.2: Works.
WordPress 2.6.1: Works.
WordPress 2.5: DomainMirror seems to work with no changes on this version, as long as the 2.3 patch is in place.

Download: Domain Mirror v1.1

Download: Domain Mirror v1.2beta

Download: WP-DomainMirror WordPress 2.3 fix

If you have more than one domain and want to point both of them at the same WordPress installation, you’ll find that it doesn’t really work very well. WordPress creates it’s own internal URLs based on the settings in General Options. This Plugin allows multiple domains to be configured within WordPress and updates the Weblog Title, WordPress Address URL and Blog Address URL on-the-fly based on the value of $_SERVER['SERVER_NAME'].

This allows one installation to show different URL paths, tagline and blog title for each domain.

What it won’t do is make one domain appear to be two, or change your domain configuration. You need to do that yourself, or have your hosting provider do it for you.

To see it in action, you can access this site via http://McAleavy.org or http://LightPainting.org. Both point to a single WordPress installation, running on a single database.

NB: It doesn’t appear to work with WordPress MU.

New in v1.1

1. You can now have a separate tagline on each domain.
2. The Admin screen has a button to copy in the current WordPress configuration to save on typing.
3. The Admin screen has buttons to clear content from whole domains and indivudual lines.

New in v1.2beta

This version is pretty new, contains quite a few changes, and may have bugs. Please use it if you’d like to help find them.

1. Theme switching.
2. SERVER_NAME / HTTP_HOST config option.
3. “no admin screen” switch.
4. More validation.
5. Added “stripcslashes”

Installation

1. Download and unpack the archive. If you downloaded the plugin from my site it will unpack to a directory named “AA-DomainMirror”, but if you got it from the WordPress plugin repository it will unpack to the direcotory “domain-mirror”. Either will work, but you may need to rename the latter to “AA-DomainMirror” if you have problems with some other plugins not seeing the changes. See below.
2. Copy the whole AA-DomainMirror directory to wp-content/plugins/ If possible, don’t change the name of the directory, as the AA- at the start is a horrible hack to ensure that WordPress loads this plugin first. This is required as any plugin loaded before it won’t be able to see the changes it makes, so will behave as if it’s still on the default domain. This puzzled me for quite a while.
3. Go to your Plugins page and activate Domain Mirror.
4. Go to the Options -> Domain Mirror page and configure as outlined below.

Upgrade

Overwrite the old version with the new version.

Usage

When enabled, Domain Mirror will change the values of Weblog Title, Tagline, WordPress Address and Blog Address automatically. Where you have hard-coded the site name or a site URL into a post or page you should replace that entry with one of the tags provided. See below.

Configuration

Click the images to expand.

You will need to set up at least 2 domains that point to the same WordPress install. With Apache you can do that with Virtual Hosts. If you are using a hosted account there may be some way to set this up through the account configuration screens. On the host I use for this site, DreamHost, you do this by logging into the Panel interface and selecting Domains >> Manage Domains. Your first domain must be Fully Hosted. For the Domain you want to set as the Mirror, click the edit button. In the edit screen there are 5 options:

1. Fully Hosted;
2. Redirected;
3. Mirrored;
4. Parked;
5. Cloaked.

DreamHost Mirror Settings

 

Select the Mirrored option, and set Domain to mirror to the name of your Fully Hosted domain. Shown here is this setting for my lightpainting.org domain, which mirrors mcaleavy.org.

Options Before

 

Your existing WordPress configuration should be left as it is. This will not be changed unless you press Save on this page when viewed from a domain other than the default. See below.

Domains Before

 

On initial activation, the Domain Mirror options screen will display a default blank entry. This default is defined in conf.inc.php – which can be edited to set different defaults. The post tags used to display the current setting of these fields in posts or pages are shown to the right. Add this text to a post or page and it will be replaced by it’s value for the current domain. This allows such posts to display properly from any configured domain.

First Domain

 

Fill in the settings for the current domain, or press the Get Current Domain button to get the values from the database. This is recommended because the General Options page will show the Domain Mirror configured settings when accessed from another domain. If you then press Save on that page those options will be written to the WordPress settings, overwriting the original settings. If you don’t have those settings in Domain Mirror, they will be lost and the original domain will not function properly until they are re-entered. If Save is not pressed, the original values will be retained and will be used again when the plugin is disabled.

Changes Saved

 

Click the Save button to record the changes. The screen will reload and display the Changes Saved banner.

New Blank Domain

 

To add another domain, click the Add New Domain button. The page will refersh with a 2nd blank domain.

Second Domain

 

Fill in the details for the 2nd domain, and click Save Changes.

SiteBefore.jpg

 

Now, when viewed using the first domain, the site remains unchanged.

Site After

 

When viewed using the second domain, the site appears as if configured for that domain.

Options After

 

The General Options screen, when accessed from the new domain, now displays the details for that domain. These options, however, are coming from the Domain Mirror configuration and not from the WordPress settings. As noted before, if save is pressed on this page these options will be written to the WordPress settings, overwriting the original settings. If you don’t have those settings in Domain Mirror, they will be lost and the original domain will not function properly until they are re-entered.

To delete a domain, press the Delete Domain button and it will be removed from the page. This change will be written to the database when you next press Save Changes. If you delete all of the entries in Domain Mirror it will return to it’s default settings. If you wish to alter these defaults you can edit the file config.inc.php in the AA-DomainMirror directory. The “X” buttons on each line can be used to clear the contents of that line and the Clear All button can be used to clear the contents of that domain setting. Again, pressing Save Changes is rquired to make these changes permanent.

1. SEDO是做什么的?
Sedo(Search Engine of Domain Name)提供域名交易和付费域名停放服务,开始于2003年,主投资商1and1,主域名sedo.com(刚开始使用esedo.com,Matt老大花了一年多的时间以8w美金买进sedo.com),国别域名:sedo.co.uk, sedo.de, sedo.fr, sedo.es, sedo.cn等. 已经有包括中文在内的近10种语言界面.

2.域名交易服务.

sedo收取10%的交易费,没有最低起价.可通过paypal支付,个人认为可信赖程度大于escrow.本人通过sedo交易数十个域名,均非常顺利.

3.付费停放(Paid Domain Parking)

此项服务,sedo并非原创,我接触最早的是DomainSponsor.目前有很多人提供此项服务,afternic, fabulous,goldkey等,但是如果大部分流量是亚洲流量的话,还是sedo最好,因为他跟google合作,关键词优化的比较好.其他的大部分不对亚洲流量付费,或者很少.

sedo最早的合作伙伴是Espotting,付费非常高,一个点击至少1欧元左右,但是后来转向google,现在国内每个点击一般是0.03欧或者更多些,我这两天还有0.02的点击.欧美的有的有1欧的或者更多的,视关键字而定.

4.付费问题

我好久没看sedo条款了,20以上就可以通过paypal支付,50以上可以电汇,接受电汇最好的是:中行的一本通

Sedo域名停放指南

如何开始：

步骤 1

输入您的域名。 如果您还没有做好，请 创建一个Sedo帐号 点击菜单“我的Sedo>>添加域名”来增加您的域名。 这需要在Sedo上停放您的域名。 没有停放在Sedo上的域名不会跟停放在Sedo的域名显示在一起的。

步骤 2

请使用以下两种方法，在Sedo上“停放” 您的域名：

方法一：域名服务器转向

首选服务器：NS1.SEDOPARKING.COM
首选服务器IP： 217.160.95.94

备用服务器：NS2.SEDOPARKING.COM
备用服务器IP： 217.160.141.42

请注意：域名服务器转向注册将会在2到3天内更新，您的域名停放页面才会显示正确。

步骤 3
一但您的域名被完全地安装在您的注册商那里，您可以使用您的帐号登录到Sedo上，然后通过点击停放域名 来追踪您停放的域名。
