WPMU may be easily installed via Softaculous Apps Installer in cPanel:
1. Go to your cPanel and find Softaculous app installer:
2. Find WordPress and its icon to install
3. Fill out the details for your website, scroll down and click Install.
NOTE: The corresponding option Enable Multisite (WPMU)
should be checked during the installation.
4.You will get a notification that WPMU is successfully installed for your domain. This is the easiest way to install WPMU for your domain.
======================================
If you have Existing installed WordPress then follow below steps
How can you check if WPMU is already enabled for your site?
You need to find the wp-config.php file. There you will see the following lines that state WPMU is enabled:
/* Multisite */
define( ‘WP_ALLOW_MULTISITE’, true );
define(‘MULTISITE’,true);
define(‘SUBDOMAIN_INSTALL’, false);
define(‘DOMAIN_CURRENT_SITE’, ‘yourdomain.com’);
define(‘PATH_CURRENT_SITE’, ‘/’);
define(‘SITE_ID_CURRENT_SITE’, 1);
define(‘BLOG_ID_CURRENT_SITE’, 1);
Turning a regular WordPress installation into WPMU
If you have a regular WordPress installation but decided to make Multisite, there is no need to re-install or remove your WordPress. You may as well enable Multisite for it following the instructions below.
We recommend you to back up the WordPress website before you start in case some steps are followed improperly.
You may begin with the wp-config.php file editing. It is possible to do it via FTP or directly in cPanel.
1. Go to your cPanel >File manager > public_html folder (or the subfolder where WordPress files are located) > choose the wp-config.php file and click Edit:
You need to add the following line in the same place as shown in the screenshot:
define(‘WP_ALLOW_MULTISITE’, true);
Once done, save the changes.
2. Log in to your Admin Dashboard and check that Network Setup has been added to your Tools menu:
Note : If you have installed wordpress using softaculous then this option will not see in wordpress because network setup is already done. You may skip the steps below. And go to step 5
You will see below
3. You need to choose whether you would like your sites to use a subdomain or sub-directories in your WordPress.
The Sub-domains option will get your sites URLs as site1.yourdomain.com,site2.yourdomain.com, etc.
The Sub-directories option will enable you to have sites URLs like yourdomain.com/site1, yourdomain.com/site2, etc. This option doesn’t require any additional adjustments.
It is not possible to have both options enabled at the same time. Once you have decided which is best for you, proceed and click Install.
4. Next, you will see the page called Create a Network of WordPress sites. Enabling network.
In order to complete enabling Multisite, wp-config.php and .htaccess files are to be modified. For this, follow the steps as described on the page (make sure you copy-paste code abstracts precisely)
Once both files are edited, your network is enabled and configured. Click on Log In and re-access your WordPress admin dashboard using the same login details.
5. The last step is the creation of a mu-plugins folder with the plugins activated by default and affecting all the sites in the WPMU installation.
Navigate to File Manager menu and locate the root folder for yourWordPress installation. Move to wp-content folder > click the New folder button in the top menu > type mu-plugins in the corresponding field > click Create a New Folder. Ensure the permissions for the newly created folder are set to 0755:
6. Now you can log into your Admin Dashboard again and check if the network is enabled:
Network Admin is a super admin that has access to the whole Network Management and all other WordPress dashboards.
Creating subdomains and subfolders.
You will need to create new sites in the WordPress Network via Network Admin.
1. Go to your WordPress admin panel > My Sites > Network Admin > Sites:
2. Click Add New to create a new site:
NOTE 1: If you have installed WPMU via Softaculous, you will have the subdirectory option (yourdomain.com/site1) set up by default, so it will be possible to add new WordPress site to the sub-directory as described below.
NOTE 2: The admin email field – if you use the email address already assigned to Super Admin or Admin of the regular WordPress installations inside the network, you will need to access the Admin Dashboard for the new site with the same details.If you use the new email address, which is not assigned to any user yet and does not exist in the WordPress database, the new user will be created, and the login details will be sent to the specified email address:
If you would like to install WordPress site to the subdomain, not to thesubdirectory, you need to do the following first:
1. Create a subdomain in domain menu in cPanel:
While creating such a subdomain, make sure to point Document Root to the root directory of the multisite installation.
2. Change Subdomain_Install option in the wp-config.php file from false to true and save the changes:
3. Once done, you can access Network Admin Dashboard and install WordPress to the subdomain:If you switch the Subdomain_Install option back to false, it will be possible to create the subdirectories again. As a result, you can switch from subdomains to subdirectories depending on the needs.
