Multiple Site Hosting

Multiple Site Hosting requires Concrete 9.0 or greater.

Concrete Multisite is a feature that allows you to run multiple sites off a single installation of Concrete. 

Prior to version 9, the Domain Mapper add-on enabled a single Concrete installation to route multiple domains to different top level pages. In version 9 this feature is fully included, and allows content editors to set up different types of sites, default permission groups across sites, default site attributes per site type, and more. 

With all sites under one shared set, Multisite makes it easy to spin up clone sites and reduce the time needed to update Concrete, themes and packages.

When should you use multi-site?

Multisite configuration can be extremely helpful in certain cases, but in others it can lead to administrative problems. It’s important to understand what Multisite is and what problems it was designed to address before you make the decision to use it. Concrete Multiple Site Hosting is best to use when you’re creating a network of sites sharing similar functionality. Ideally, this similar functionality has been added through Blocks and themes. If your sites consist of widely different sites and their functionality, then multisite is not a good fit for you.

Before you Begin

Before you begin, you need to make sure that you have added a canonical url for your main Concrete installation. In the Dashboard, Go to System & Settings -> Under SEO & Statistics, click on URLs and Redirection. Add your site canonical/main URL, and click the Save button.

Next, you must enable advanced permissions. To turn ON the advance permissions, from your Concrete Dashboard go to System & Settings -> under Permissions & Access, click on Advanced Permissions and click on Enable Advanced Permissions.

Enable Multi-Site and Set it Up

Before you start creating Multisites on your Concrete installation, let’s first enable Multisite hosting. To do that, from your Concrete dashboard, Navigate to System & Settings, click on Multisite Settings under Multiple Site Hosting. Now, click on Enable Multiple Sites to enable Multisite setup on your Concrete installation.

Next, create a new site type.

Create a New Site Type

Before you start creating a Site type in your Concrete multisite installation, let’s first understand what does Site type means in Multisite Hosting in Concrete.

What is a Site Type in Concrete Multisite Hosting?

Before you create a site in Concrete Multisite Hosting, you can create a Site type for it. A site type is nothing but the categorization of the site you can create inside it. Multiple sites of the same site type can be created. Site types are created in advance, before sites are added. 

An example of what a site type is might be helpful. Let's say you're running a network of restaurant websites from your Concrete installation. Here are the site's you hope to build, all using your single "Restaurant Theme" theme.

  • Ray's Pizza
  • Bob's Burgers
  • Sandy's Salads

For this example, you'd probably create a single site type named Restaurant. You'd set it up to use your Restaurant Theme theme, and the proper default page template. Then, you can create each one of the sites above, using the Restaurant site type.

While creating a new site, you can choose which theme and template you want to apply to all the sites inside that site type. But also Concrete Multisite Hosting gives the flexibility to choose or change theme on site level.

Let’s say you have created a new site type and have chosen the Elemental theme inside it. Now when you add a new site the Elemental theme will be automatically applied to this new site. But if you wish to apply a different theme to that site then you can still have the option to apply a different theme to it.

Now since you know about what site type means, let’s create a new site type.
 

  1. To create a new site type, go to System & Settings > under Multiple Site Hosting, click on Site Types.
  2. Click on Add Site Type.
  3. Enter the Handle - Handle of your Site type, Name - Name of your Site type, Theme - Choose a default theme which will be automatically applied to all new sites added in this site type, Template - Choose a homepage, Homepage will be automatically created once a new site is created inside this Site type.
  4. Click on Create Site Type.

Create a New Site

Now you have created a site type, let’s create a new site, to create a new site

  1. Go to System & Settings > under Multiple Site Hosting, click on Sites & Domains.
  2. Now click on Add Site.
  3. If you have created a Site Type before then it will give you an option to choose the Site type in which you want to add this site. If you don’t have any Site Types created then it will automatically be assigned to Default Site Type.
  4. Now enter the Handle - Give your site a handle, Name - Add a name to your site, Canonical URL - Add canonical url to your site, Default Timezone - Choose a Default timezone for your site. For the Canonical URL, you need to make sure that you have made the right configuration for your domain in DNS. Also make sure that you have the correct web server(Apache/Nginx) configuration to support that domain.

Use the Site Selector to Change Site Settings

Once you have created a new site, it will add the site selector dropdown button to your Dashboard toolbar. Sometimes this selector will be set to "Global" and will not be changeable:

The Global selector on the top bar in dashboard represents the pages or attributes which are set as Global and not site specific.

On pages where your sites do appear in this selector, you can choose the site to which you'd like to make these settings apply. For example on Dashboard System and Settings > Basics Name, saving the updated site name will only affect the site that shows in the site-wide selector in the toolbar.
