[wp-edu] How do you manage a site with 100+ sub sites with WordPress?

[D'Arcy L Norman]

Our server is pretty tiny in comparison - only 2018 sites now, with 4195 users. I view having MultiDB (or HyperDB) set up as more of insurance in case things go south. We had a period where the database server we had available was horribly underpowered, and MultiDB would have let us spread the load across several servers easily. (we wound up just throwing resources at the server, and the problem went away - but it's good to have options).

D'Arcy, what numbers are you at now? We aren't seeing performance problems yet at 4,000 sites but I expect to go to hyperdb soon.

I think my colleague Luke at Baruch College (10,000 or so sites) is using SharDB.

The biggest tweak you can do is add database scaling, so you don't hit the max-tables limit in a single database. HyperDB or MultiDB would do that - I use MultiDB on UCalgaryBlogs.ca<http://UCalgaryBlogs.ca> and it works great. Spreads the tables across several databases (16, 256 or 4096), which can hold up to "millions" of blog sites. Haven't had enough to test that claim, though. The 16 database config scales to 50,000 blogs. That should hold us for a few years.

Multi-DB: https://premium.wpmudev.org/project/multi-db/

HyperDB: https://wordpress.org/plugins/hyperdb/

I started with MultiDB, back before HyperDB was a thing. If I was starting fresh, I'd go with HyperDB because it's free, maintained by Automattic, and basically what's used on WordPress.com<http://WordPress.com>. MultiDB woks find, but requires a subscription fee. I haven't had the energy to migrate UCalgaryBlogs to it, because it works.

These are class sites and student eportfolios, so we do not ever retire or purge sites.

Students do return to old sites and take them up again even if they have been inactive for a long time, even years.

Part of our policy and what we guarantee to students is that these sites will remain available until and unless the students themselves delete them (except in the case of serious violations of our community guidelines...has not happened yet).

What sort of site retirement policy do you maintain? How do admin know when to purge a site from a set of 4,000?

WordPress multisite works very well for this. We currently have, on our big multisite install, over 4,000 sites, with many different themes. We aren't currently using domain mapping but may soon.

My CUNY colleagues at Baruch College have a similar set up with far more sites.

Hi Ryan,

On the UBC CMS we have just over 900 domain mapped sites.
We run one Network within multi site and have one central theme and allow users to map their domains using the Domain Mapping Plugin.

It's worked well for users so far.

We are looking at going with WordPress with at our college, currently have about 100+ sub sites under one master, each with unique navigation and content.

How do you manage this in WordPress?
