# Local deployment

It is possible to download the Algo scripts to your own Ubuntu 18.04 server and run the scripts locally.

In order to start, you need to install Ansible. Installing Ansible via pip requires pulling in a lot of dependencies, including a full compiler suite. It would be easier to use apt, however, Ubuntu 18.04 only comes with Ansible 2.0.0.2. The easiest solution is to install the Ansible PPA for a newer version of Ansible via apt, however, using a PPA requires installing `software-properties-common`.

tl;dr:

```shell
sudo apt-get install software-properties-common && sudo apt-add-repository ppa:ansible/ansible
sudo apt-get update && sudo apt-get install ansible python-pip build-essential python-dev libssl-dev libffi-dev
pip install virtualenv
pip install --upgrade pip
git clone https://github.com/trailofbits/algo
cd algo
python -m virtualenv env && source env/bin/activate && python -m pip install -U pip && python -m pip install -r requirements.txt
./algo
```

**Warning**: Algo is intended to be run on a standalone server. If you run Algo on your existing server, the iptables rules will be overwritten. If you don't want to overwrite the rules, you must deploy via `ansible-playbook` and skip the `iptables` tag as described in [deploy-from-ansible.md](deploy-from-ansible.md). Other changes are also made, which can break other services running on your server (web, mail, etc.).
