I want to install Flarum on the subdomain "forum.domain.com". I created a Flarum folder inside the subdomain folder. Then I followed the documentation, but nothing happened, an error is shown. When I move all the files in the Flarum folder to the subdomain, it works fine. How do I configure the files for this?

forwebsite2019 If you moved the files, you need to change the domain in your config file and then run composer update to make sure everything is talking to each other correctly.

How can i install to "forum.domain.com/flarum"? then when i visit to forum.domain.com then forum run normally.

Karl How can i install to "forum.domain.com/flarum"? then when i visit to forum.domain.com then forum run normally. flarum doc is for install to forum.domain.com and domain.com.

About Install to "forum.domain.com"

Karl

forwebsite2019 in the documents, you can see that there are special rewrite procedures to get that /forum you're asking for. Otherwise, the stock install has it so you need to point the /public folder as document root, which will have the address show /public as the base domain instead: site.com

Karl Can you tell me the step by step guide to install flarum. ex: 1,2. doc is complicated.

Karl

forwebsite2019 let's clarify the goal first.
Are you wanting to install: forum.subdomain.com? or domain.com/forum?
Easiest and recommended is forum.subdomain.com as your sensitive files are completely hidden from the public.

I want install to "forum.subdomain.com"

Karl

forwebsite2019 go to where you want to install flarum via SSH and run the composer command to pull the files. Afterwards, point the document root to /public and navigate to forum.subdomain.com

forwebsite2019 You don't have to create a flarum folder if you do what @Karl said. It creates all the folders where they are supposed to be.

forwebsite2019

ernestdefoe Check screenshot. no public folder no flarum folder. everything inside in forum.subdomain.com. i move all the files inside flarum, public folder to forum.subdomain.com.

Karl

forwebsite2019 you should not be "moving" anything. You probably have it completely missed.
You need to go to wherever you're going to have Flarum installed and then run the composer command. This will populate everything you need in that directory.
Example: cd /public_html then run composer for Flarum install. Afterwards, point root directory: /public_html/public and then navigate to: forum.subdomain.com

My example, My subdomain folder created outside of public_html.
cd forum.subdomain.com. then i run install command. flarum create a flarum folder inside subdomain folder. then ?

ernestdefoe

forwebsite2019 you don't create any folders. Run the ssh command inside the directory for your subdomain and then configure your document root to the public directory that the ssh command created and then go to subdomain.domain.tdl and follow the instructions.

ernestdefoe how to configure document root?
check folder
after install, forum.subdomain.com/flarum/public folfer and other files.

ernestdefoe

forwebsite2019 what control panel are you using to manage your site? It's going to be different for each one.

forwebsite2019

ernestdefoe Using cpanel.

ernestdefoe

forwebsite2019 follow the instructions on this page https://support.cpanel.net/hc/en-us/articles/360057802373-How-can-I-change-the-document-root-for-an-Addon-Domain-or-Subdomain it should point to the /public directory in your subdomain directory.

forwebsite2019

Check screenshot. everything inside in forum.subdomain.com. i move all the files inside flarum and public folder to forum.subdomain.com. after
edit this file $site = require './site.php'; and
'base' => DIR,
'public' => DIR,
'storage' => DIR.'/storage',

then forum works,

Karl

forwebsite2019 if you look on the browser, does the site load as forum.subdomain.com/public or just forum.subdomain.com

forwebsite2019

just "forum.subdomain.com"
because no public and flarum folder. all the files are in on place.

forwebsite2019

Karl update
just "forum.subdomain.com"
because no public and flarum folder. all the files are in on place.

install flarum using this command
composer create-project flarum/flarum this command not work composer create-project flarum/flarum .
after flarum create a flarum folder. then i move all the files inside flarum and public folder to forum.subdomain.com.
