Wordpress multisite runs great on Digital Ocean’s One Click Wordpress install setup.
However problems happen when trying to add Letsencrypt to the installation for each domain the multisite uses. The typical multisite setup uses subdirectories for each subsite. This is done by wordpress and works fine with stock virtual host settings created by the One Click install from Digital Ocean.
However, certbot doesn’t like this and expects a virtualhost to be declared/setup in apache for each domain in your Wordpress Multisite site list.
After googling, all examples I see don’t use the same language/code examples in the sites-available as Digital Ocean’s one click setup uses. Here’s what Digital Ocean creates with the setup:

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

        <Directory /var/www/html/>
            Options FollowSymLinks
            AllowOverride All
            Require all granted

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
RewriteEngine on
RewriteCond %{SERVER_NAME} =YourDomainNameHere.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]


RewriteCond %{SERVER_NAME} =YourDomainNameHere.com

is confusing as tutorials on virtualhosts in Ubuntu 16.04 doesn’t cover this code line.

So… for this situation… which is not currently covered in the Letsencrypt or Wordpress tutorials on Digital Ocean… what is the proper way to add in the domains in apache ALL for the same installation folder ( /var/www/html ) so that Letsencrypt Certbot will install additional domain certificates properly?

Help would be most appreciated. thank you.

Expanding a single certificate is also not recommended for unrelated domains from what I’ve gathered in tutorials.

Basically, each domain needs it’s OWN .conf file as well as each file having the Servername declared. Then after system linking into sites-enabled and an apache2 restart, certbot will install the additional certificates properly. See the thread at letsencrypt for more details.

  • I tried to follow what you were suggesting but Am too novice to figure it out!!

    I would like to set up WordPress multi site to set up a handful of different sites on one digital ocean droplet… each with their own domain, and letsencrypt certificate.

    Would you be willing to write out a tutorial article on how to set this up on the digital ocean and, and also the commandline codes needed to be entered via SSH? 🙏

    • I need help with this exact same request! I can pay a Developer to assist me with enabling SSL certs via certbot via letsencrypt.org for a multi-site virtualhost Wordpress environment on a Digitalocean ubuntu droplet, please!
