cerebrate/INSTALL/INSTALL.md

Requirements

An Ubuntu server (18.04/20.04 should both work fine) - though other linux installations should work too.

• apache2 (or nginx), mysql/mariadb, sqlite need to be installed and running
• php version 8+ is required
• php extensions for intl, mysql, sqlite3, mbstring, xml need to be installed and running
• php extention for curl (not required but makes composer run a little faster)
• composer

Network requirements

Cerebrate communicates via HTTPS so in order to be able to connect to other cerebrate nodes, requiring the following ports to be open:

• port 443 needs to be open for outbound connections to be able to pull contactdb / sharing group information in
• Cerebrate also needs to be accessible (via port 443) from the outside if:
  • you wish to pull interconnect local tools with remote cerebrate instances
  • you wish to act as a hub node for a community where members are expected to pull data from your node

Cerebrate installation instructions

It should be sufficient to issue the following command to install the dependencies:

• for apache

sudo apt install apache2 mariadb-server git composer php-intl php-mbstring php-dom php-xml unzip php-ldap php-sqlite3 php-curl sqlite libapache2-mod-php php-mysql

• for nginx

sudo apt install nginx mariadb-server git composer php-intl php-mbstring php-dom php-xml unzip php-ldap php-sqlite3 sqlite php-fpm php-curl php-mysql

Clone this repository (for example into /var/www/cerebrate)

sudo mkdir /var/www/cerebrate
sudo chown www-data:www-data /var/www/cerebrate
sudo -u www-data git clone https://github.com/cerebrate-project/cerebrate.git /var/www/cerebrate

Run composer

sudo mkdir -p /var/www/.composer
sudo chown www-data:www-data /var/www/.composer
cd /var/www/cerebrate
sudo -H -u www-data composer install

Create a database for cerebrate

With a fresh install of Ubuntu sudo to the (system) root user before logging in as the mysql root

sudo -i mysql -u root

From SQL shell:

mysql
CREATE DATABASE cerebrate;
CREATE USER 'cerebrate'@'localhost' IDENTIFIED BY 'YOUR_PASSWORD';
GRANT USAGE ON *.* to cerebrate@localhost;
GRANT ALL PRIVILEGES ON cerebrate.* to cerebrate@localhost;
FLUSH PRIVILEGES;
QUIT;

Or from Bash:

sudo mysql -e "CREATE DATABASE cerebrate;"
sudo mysql -e "CREATE USER 'cerebrate'@'localhost' IDENTIFIED BY 'YOUR_PASSWORD';"
sudo mysql -e "GRANT USAGE ON *.* to cerebrate@localhost;"
sudo mysql -e "GRANT ALL PRIVILEGES ON cerebrate.* to cerebrate@localhost;"
sudo mysql -e "FLUSH PRIVILEGES;"

create your local configuration and set the db credentials

sudo -u www-data cp -a /var/www/cerebrate/config/app_local.example.php /var/www/cerebrate/config/app_local.php
sudo -u www-data cp -a /var/www/cerebrate/config/config.example.json /var/www/cerebrate/config/config.json
sudo -u www-data vim /var/www/cerebrate/config/app_local.php

mod_rewrite needs to be enabled if using apache:

sudo a2enmod rewrite

Simply modify the Datasource -> default array's username, password, database fields This would be, when following the steps above:

    'Datasources' => [
        'default' => [
            'host' => 'localhost',
            'username' => 'cerebrate',
            'password' => 'YOUR_PASSWORD',
            'database' => 'cerebrate',

Run the database schema migrations

sudo -u www-data /var/www/cerebrate/bin/cake migrations migrate
sudo -u www-data /var/www/cerebrate/bin/cake migrations migrate -p tags
sudo -u www-data /var/www/cerebrate/bin/cake migrations migrate -p ADmad/SocialAuth

Clean cakephp caches

sudo rm /var/www/cerebrate/tmp/cache/models/*
sudo rm /var/www/cerebrate/tmp/cache/persistent/*

Create an apache config file for cerebrate / ssh key and point the document root to /var/www/cerebrate/webroot and you're good to go

For development installs the following can be done for either apache or nginx:

# Apache
# This configuration is purely meant for local installations for development / testing
# Using HTTP on an unhardened apache is by no means meant to be used in any production environment
sudo cp /var/www/cerebrate/INSTALL/cerebrate_apache_dev.conf /etc/apache2/sites-available/
sudo ln -s /etc/apache2/sites-available/cerebrate_apache_dev.conf /etc/apache2/sites-enabled/
sudo service apache2 restart

OR

# NGINX
# This configuration is purely meant for local installations for development / testing
# Using HTTP on an unhardened apache is by no means meant to be used in any production environment
sudo cp /var/www/cerebrate/INSTALL/cerebrate_nginx.conf /etc/nginx/sites-available/
sudo ln -s /etc/nginx/sites-available/cerebrate_nginx.conf /etc/nginx/sites-enabled/
sudo systemctl disable apache2 # may be required if apache is using port
sudo service nginx restart
sudo systemctl enable nginx

Now you can point your browser to: http://localhost:8000

To log in use the default credentials below:

• Username: admin
• Password: Password1234
