WordPress 3.0版本中,已经开始提供了创建一个多站点博客网络的功能。此文是关于如何创建这么一个网络的说明,最终就像创建了一个你的个人版WordPress.com博客网站一样.

NOTE: 如果你当前已经在用WordPress MU这个插件的话,你就不需要做以下步骤,因为你的网络功能已经开启了。当你更新到3.x的某个版本分支时,系统将会提示你更新.htaccess里的规则以设置多站点网络。




如果想配置多站点博客网络,你至少应该对UNIX、Linux的管理操作有基本了解。最好能对WordPress开发、PHP、HTML 和 CSS 有一定认识.





  • 子域名:例如site1.example.comsite2.example.com
  • 子目录:例如example.com/site1example.com/site2

It is also possible later, through use of a plugin such as WordPress MU Domain Mapping, to map individual sites to independent domain names.

Sub-directory sites
It works with the use of the mod_rewrite feature on the server having the ability to read the .htaccess file, which will create the link structure.
If you are using pretty permalinks in your blog already, then subdirectory sites will work as well.
Sub-domain sites
It works using wildcard subdomains. You must have this enabled in Apache, and you must also add a wildcard subdomain to your DNS records. (See Step 2 how to set up.)
Some hosts have already set up the wildcard on the server side, which means all you need to add is the DNS record.
Some shared webhosts may not support this, so you may need to check your webhost before enabling this feature.

WordPress 必要的设置

  • Giving WordPress its own directory will not work in WordPress 3.0 with multisite enabled. It interferes with the member blog lookup.
  • You cannot create a network in the following cases:
    • "WordPress address (URL)" is different from "Site address (URL)".
    • "WordPress address (URL)" uses a port number other than ':80', ':443'.
  • You cannot choose Sub-domain Install in the following cases:
    • WordPress install is in a directory (not in document root).
    • "WordPress address (URL)" is localhost.
    • "WordPress address (URL)" is IP address such as
  • You cannot choose Sub-directory Install in the following cases:
    • If your existing WordPress installation has been set up for more than a month, due to issues with existing permalinks. (This problem will be fixed in a future version. See Switching between subdomains and subfolders for more inforamtion.)

(See wp-admin/network.php for more detail)

第一步:备份你的 WordPress

你的 WordPress 将会在创建站点网络时升级,请于操作前备份你的数据



Sub-domain sites work with the use of wildcard subdomains. This is a two-step process:

  1. Apache 必须设置为支持通配符。
    1. Open up the httpd.conf file or the include file containing the VHOST entry for your web account.
    2. 添加此行:
      ServerAlias *.example.com
  2. 在DNS解析中添加一行带有通配符的子域名解析记录:
    A *.example.com

If you can't access httpd.conf and your server uses CPanel. Make a sub-domain named "*" (wildcard) at your CPanel (*.example.com). Don't give names to subdomains at CPanel. If you can't do that, contact your host.

如果你的服务器使用 Plesk Panel 控制面板. There are several steps that differ when setting up the server for wildcard subdomains on a server using Plesk Panel compared to a server using cPanel (or no control panel). This article Configuring Wildcard Subdomains for multi site under Plesk Control Panel‎ details all the steps involved. Although the instructions are comprehensive, the actual work only takes a couple of minutes.

如果你的服务器使用 DirectAdmin 控制面板。 (2011.01)

  1. 点击 "User Panel" -> DNS Management -> 添加下面三项:* A将“”替换为你服务器的IP)
  2. 单击 "Admin Panel" (如果你没有 "admin panel" 选项,你需要让你的空间提供商做这件事) -> 自定义 Httpd -> yourdomain.com -> 在文本框中粘贴并保存此行:ServerAlias *.|DOMAIN|(如果你需要撤销此操作,返回该行,删除文本框中的文本并保存)

To enable the Network menu item, you must first define multisite in the wp-config.php file.

打开 wp-config.php 并且 /* That's all, stop editing! Happy blogging. */的上方加入此行:

define('WP_ALLOW_MULTISITE', true);


This will enable the Network menu item to appear in the Tools menu. Visit Administration > Tools > Network to see the screen where you will configure certain aspects of our network.

Tools Network SubPanel
Addresses of Sites in your Network
You are given the choice between sub-domains or sub-directories (if none of the above applies). This means each additional site in your network will be created as a new virtual subdomain or subdirectory. you have to pick one or the other, and you cannot change this unless you reconfigure your install. See also Before You Begin.
  • Sub-domains -- like site1.example.com and site2.example.com
  • Sub-directories -- like example.com/site1 and example.com/site2
Network Details
There are filled in automatically.
Server Address
The Internet address of your network will be example.com.
Network Title
What would you like to call your network?
Admin E-mail Address
Your email address.

Double-check they are correct and click the Install button.

You may receive a warning about wildcard subdomains. Check Setting Wildcard Subdomains.

Warning! Wildcard DNS may not be configured correctly!

The installer attempted to contact a random hostname (13cc09.example.com) on your domain.

To use a subdomain configuration, you must have a wildcard entry in your DNS. This usually means adding a * hostname record pointing at your web server in your DNS configuration tool.

You can still use your site but any subdomain you create may not be accessible. If you know your DNS is correct, ignore this message.


The rest of the steps are ones you must complete in order to finish.

Tools Network Created

0. First, back up your existing wp-config.php and .htaccess files.
1. Create a blogs.dir directory under /wp-content/
This directory is used to stored uploaded media for your additional sites and must be writable by the web server. They should be CHOWNed and CHMODed the same as your wp-content directory.
2. Add the extra lines your WordPress installation generates into your wp-config.php file.
These lines are dynamically generated for you based on your configuration.
Edit the wp-config.php file while you are logged in to your sites admin panel.
Paste the generated lines immediately above /* That's all, stop editing! Happy blogging. */.
Remove the earlier placed define('WP_ALLOW_MULTISITE', true); line only if you wish to remove the Network menu in the admin area. You may choose to leave this to be able to access the .htaccess rules again..
3. Add the generated mod_rewrite rules to your .htaccess file, replacing other WordPress rules.
(If there isn't one, then create it.)
These lines are dynamically generated for you based on your configuration.
4. Log in again.
Once the above steps are completed and the new wp-config.php & .htaccess files are saved, your network is enabled and configured. You will have to log in again. click "Log In" to refresh your Adminstration Panel. If you have problems logging back in, please clear your browser's cache and cookies.


You will now see a new menu section called Super Admin. The menus contained in there are for adding and managing additional sites in your network. Your base WordPress install is now the main site in your network.

Go Super Admin > Options panel to configure network options, and then create sites and users.


Here are some additional things you might need to know about advanced administration of the blog network.


By design, all users who are added to your network will have subscriber access to all sites on your network.

Also, site admins cannot install new themes or plugins. Only the Network Admin (aka Super Admin) has that ability.


While permalinks will continue to work, the main blog (i.e. the first one created) will have an extra entry of blog, making your URLs appear like domain.com/blog/YYYY/MM/POSTNAME.

This is by design, in order to prevent collisions with SubFolder installs. Currently there is no easy way to change it, as doing so prevents WordPress from auto-detecting collisions between your main site and any subsites. This will be addressed, and customizable, in a future version of WordPress.

Also note that the blog prefix is not used for static pages which will be accessible directly under the base address, e.g. domain.com/PAGENAME. If you try to create a static page in the first blog with the name of another existing blog, the page's permalink will get a suffix (e.g. domain.com/PAGENAME-2). If you create a new blog with the slug of an existing static page, the static page will not be reachable anymore. To prevent this, you can add the names of your static pages to the blacklist so that no blog with this name can be created.

WordPress 插件

WordPress Plugins now have additional flexibility, depending upon their implementation across the network.
  • Site Specific Plugins: WordPress Plugins to be activated or deactivated by an individual blog owner are stored in the plugins directory. You need to enable the Plugins page for individual site administrators from Network > Options.
  • Network Plugins: WordPress Plugins stored in the plugins directory can be activated across the network by the super admin.
  • Must-Use Plugins: Plugins to be used by all sites on the entire network may also be installed in the mu-plugins directory as single files, or a file to include a subfolder. Any files within a folder will not be read. These files are not activated or deactivated; if they exist, they are used.


Global terms are disabled in WordPress 3.0 by default. You can use the Sitewide Tags WordPress Plugin or other similar Plugins to incorporate global tags on the portal/front page of the site or on specific pages or blogs within the network to increase navigation based upon micro-categorized content.


If you have had WordPress installed for longer than a month and are attempting to activate the network, you will be told to use Sub-domain sites. This is in order to ensure you don't have conflicts between pages (i.e. example.com/pagename ) and sites (i.e. example.com/sitename ). If you are confident you will not have this issue, then you can change this after you finish the initial setup.

In your wp-config.php file, you'll want to change the define call for SUBDOMAIN_INSTALL:

Use SubDomains
define( 'SUBDOMAIN_INSTALL', true );
Use SubFolders
define( 'SUBDOMAIN_INSTALL', false );

You'll also have to change your .htaccess to the new setup. Be aware, you may have issues if you attempt this after being on one setup or the other for any length of time, so proceed with caution.

.htaccess 和 Mod Rewrite

Unlike Single Site WordPress, which can work with "ugly" Permalinks and thus does not need Mod Rewrite, MultiSite requires its use to format URLs for your subsites. This necessitates the use of an .htaccess file, the format of which will be slightly different if you're using SubFolders or SubDomains. The examples below are the standard .htaccess entries for WordPress SubFolders and SubDomains, when WordPress is installed in the root folder of your website. If you have WordPress in it's own folder, you will need to change the value for RewriteBase appropriately.
