Installing certificates for WP Multisite

Installing certificates for WP Multisite

WordPress Multisite allows you to manage multiple websites on subdomains within a single domain using a single WordPress core.

Typically, a wildcard SSL certificate for such a site in ispmanager 6 is sufficient. However, if you need to install a separate certificate for individual subdomains or a subset of subdomains, you will have to manually configure a new virtual host in the web server configuration.

First, in the Website aliases field in the site settings, enter the primary domain name in the *.domain.com format.

Next, if you use Apache exclusively, in the site's configuration file, copy and paste next to it the VirtualHost block with port 443 specified, then change the values ​​of the following directives:

  • ServerName - specify the subdomain or subdomains for which a separate SSL certificate will be used;
  • ServerAlias ​​- delete the value or directive entirely;
  • SSLCertificateFile - specify the path to the new certificate;
  • SSLCertificateKeyFile - specify the path to the new certificate's private key.

If you use Nginx, copy and paste next to it the server block containing the ssl_certificate directive, then replace the values ​​of the following directives:

  • server_name - specify the subdomain or subdomains for which a separate SSL certificate will be used;
  • ssl_certificate - specify the path to the new certificate;
  • ssl_certificate_key - specify the path to the new certificate's private key.

Certificate files added via ispmanager 6 are located at /var/www/httpd-cert/<username>/.
