## Requirements
An Ubuntu server (20.04/22.04 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:
### Note for Ubuntu 20.04 :
You will need to type this command first to be able to download php8 otherwise php 7.4 will be install instead.

Clean cakephp caches

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:
```bash
# 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
```bash
# 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
