As you can see from the official website, Wordpress3.0 and later versions support multi-site functions. Only one Wordpress program is installed:

1. You can create multiple wordpress sites, either subdomains or subdirectories.
2. You can have an independent blog background and address based on the subdomain name.
3. The administrator can set the topics that are open to the site.
4. The administrator can configure the plug-in for each site.
5. Multiple Sites share "user database tables", that is, tables wp_usermeta and wp_users, and some other data tables (wp_blogs, wp_site, wp_singnups, wp_registration_log, wp_blog_versions ), others are independent database tables.

/** Enable woredpress multi-site support */define ('wp _ ALLOW_MULTISITE ', true );

3. Go to the wordpress background, choose tools> click Configure network"

1) if you want to use a second-level domain name, you can go to "Settings"> "General" to remove the www. Of the site address (URL.
2) in this case, the DB account must have the create table permission; otherwise, the table creation fails.
4. If the plug-in is not disabled, you will be prompted to disable all plug-ins first.

5. After being disabled, you can create it. If it is not a new installation, a message is displayed:

Sub-domain name installation because your current installation is not brand new, you can only use sub-domain names for sites in your WordPress network. To install the SDK in a subdirectory of the primary site, you need to modify the fixed link structure, which may damage the existing link.

6. Click "Install" and the prompt is as follows:

Follow the instructions to complete the operation.
7. Click "Install" and follow the prompts to complete related configuration.
8. After configuration, go to the background again. The "my site"> "manage network" option menu will appear in the header. Next you can manage or create a site, you can also enable themes or plug-ins for other sites.
