new multisite domain features and installing letsencrypt oddities

  • So I’ve decided to go ahead with managing a multisite install, in order to host multiple domains/multiple websites that pretty much don’t relate to one another.

    In looking at the set up I saw a lot about WordPress no longer needing additional plugins for setting up separate domains for each site. I essentially set up my Debian 9 server with Nginx to point to a normal single web domain (domain1.com) and then went into WordPress and pointed the three current sites to domain1.com, domain2.com, domain3.com and everything worked like magic. No special server blocks or anything.

    But… Now how exactly am I supposed to add letsencrypt certs on top of this? All the guides that people have posted appear to relate to older iterations of multisite installs that required more prep than what I’m currently running. Anyone have any helpful leads on where to go from here?

    running Debian 9, php7, Nginx. WordPress 5.03

    Thanks!

  • How are you requesting your LE certs?

    Unless you’re hosting a ginormous number of domains under your single Multisite installation, the easiest way would be to use a SINGLE SAN certificate. Just include all the additional domains in the CSR. I believe LE’s current limit is 100 domains in a SAN certificate request.

    I could use some help setting up my ssl/multisite install.

    I used certbot to generate my certificates successfully. But when I go into the website dashboard and navigate to Settings -> SSL there is a message that says “No SSL detected”.
    I’m use AWS Lightsail so that isn’t a control panel to implement SSL…

    Thanks for any help that you can provide.

    But when I go into the website dashboard and navigate to Settings -> SSL there is a message that says “No SSL detected”.

    Did you point your vhost’s config to the location of the cert files you generated with certbot? Are you able to open the root URL or any static resources (readme.html, license.txt, images, etc) over HTTPS? What OS and web server software are you using?

    I guess what I need is a How-to install the SSL on an Ubuntu system. I’ve created the certificates… I need to make apache aware of them.
