Hi, If anyone wants the steps to get flarum beta3 installed on their Cpanel you can do as follows:

cd ~
mkdir bin
mkdir bin/composer
curl -sS https://getcomposer.org/installer | php
mv composer.phar bin/composer

Determine the location of your php-cli (needed later on) by typing:

which php-cli

If the above fails, use

 which php

It should return the path, such as /usr/bin/php-cli, /usr/php/54/usr/bin/php-cli , etc.

You should now browse to your cpanel home directory and edit ~/.bashrc and make sure this line is at the top:

[ -z "$PS1" ] && return

Adding it if it is not

Then add this alias to the bottom (using the php-cli path that you determined earlier):

alias composer="/usr/bin/php-cli ~/bin/composer/composer.phar"

Finish with these commands:

source ~/.bashrc
composer --version

Then navigate to public_html and make a directory for the forum e.g

cd public_html
mkdir forum
cd forum

Then run the flarum beta3 installer commands in the directory forum or whatever directory you created

composer create-project flarum/flarum . --stability=beta

Then load your browser and navigate to the installer www.tld.com/forum and enter your database and forum details.

Note the s9e-mediaembed-0.2.1 is not working with the beta3 as I've noticed, will have to wait till it is marked compatible with beta3.
