I want multiple install but same database

Justoverclock

i think that if both are pointing to the same database and are using the same table prefix then yes, everything you do to one will show up on both.

Justoverclock yes but i want use different tags and blog post extension. Blog and tags extension not supporting using multi language.

HasanMerkit mmmhhh i do not want to provide wrong information, but in this case if think you need to
use same database with different prefixes for the forums, and then, in one of these forums, you need an extension that modify the user db table (to point to your correct users table).

but maybe here you need someone more expert.

Flarum doesn't have multi-site support out of the box.

It's something an extension could implement, but I don't think such an extension exists at this time.

Two different Flarum installs can coexist in a single database with separate prefixes, but they will act like independent apps, so no different from using two different databases.

Just re-using the users table across two separate Flarum installs would lead to lots of issues regarding events, notifications and features added by extensions.

If the goal is only for password reuse and/or global sign in, a combination of a Laravel app + the Passport auth extension + some custom code for syncing users + custom code to apply global cookies could be used to make another app the authentication server and delegate Flarum installs to just oauth clients of the login app.
