Configure blogs for different domains with different SSL certificates

This section assumes:

  • You have a working WordPress Multisite installation
  • Your server has a static IP address
  • You are able to log in to your server console using a tool like PuTTY (Windows) or SSH (Linux and Mac OS X)
  • You own at least one custom domain name for which you can configure DNS settings
  • You have defined your primary domain and blog as described here and you are able to log in to the WordPress Multisite dashboard.
  • You have added one or more WordPress Multisite blogs with different domains as described here .

Follow these steps:

  • In order to set different SSL certificates for each new domain, configure each domain as a virtual host. Edit the /opt/bitnami/apache/conf/vhosts/wordpress-https-vhost.conf file and add a new virtual host for each new domain. The following code could be taken as an example:

      <VirtualHost 127.0.0.1:443 _default_:443>
    ServerName yourserverdomain.com
    ServerAlias *.yourserverdomain.com
    SSLEngine on
    SSLCertificateFile "/opt/bitnami/apache/conf/bitnami/certs/new_server.crt"
    SSLCertificateKeyFile "/opt/bitnami/apache/conf/bitnami/certs/new_server.key"
    DocumentRoot /opt/bitnami/wordpress
    <Directory "/opt/bitnami/wordpress">
      Options -Indexes +FollowSymLinks -MultiViews
      AllowOverride None
      Require all granted
      # BEGIN WordPress fix for plugins and themes
      # Certain WordPress plugins and themes do not properly link to PHP files because of symbolic links
      # https://github.com/bitnami/bitnami-docker-wordpress-nginx/issues/43
      RewriteEngine On
      RewriteRule ^bitnami/wordpress(/.*) $1 [L]
      # END WordPress fix for plugins and themes# BEGIN nip.io redirection
      RewriteEngine On
      RewriteCond %{HTTP_HOST} ^([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})(:[0-9]{1,5})?$
      RewriteRule ^/?(.*) %{REQUEST_SCHEME}://%1.nip.io%2/$1 [L,R=302,NE]
      # END nip.io redirection# BEGIN WordPress Multisite
      # Using subdomain network type: https://wordpress.org/support/article/htaccess/#multisite
      RewriteEngine On
      RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
      RewriteBase /
      RewriteRule ^index\.php$ - [L]
      # add a trailing slash to /wp-admin
      RewriteRule ^wp-admin$ wp-admin/ [R=301,L]
      RewriteCond %{REQUEST_FILENAME} -f [OR]
      RewriteCond %{REQUEST_FILENAME} -d
      RewriteRule ^ - [L]
      RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
      RewriteRule ^(.*\.php)$ $1 [L]
      RewriteRule . index.php [L]
      # END WordPress Multisite
    </Directory>
    Include "/opt/bitnami/apache/conf/vhosts/htaccess/wordpress-htaccess.conf"
  </VirtualHost>

    Remember to change the ServerName and ServerAlias directives to the correct values.

    To specify a different SSL certificate for each domain, update the paths to the corresponding certificate files in the SSLCertificateFile and SSLCertificateKeyFile directives.

  • After ensuring that the certificates are properly generated and configured in the /opt/bitnami/apache/conf/vhosts/wordpress-https-vhost.conf file, restart Apache to apply the changes.

      $ sudo /opt/bitnami/ctlscript.sh restart apache
