# Installing toit

The test suite requires Python 3.3 and relies on a number of other packages. These need to be installed for the test suite to function.
To install Python 3.3 in CentOS 7, an additional repository, Software Collections (see https://www.softwarecollections.org/en/scls/rhscl/python33) should be enabled.

Install the requirements as specified below.

---
## Enable Software Collections (SCL)

```bash
yum -y install scl-utils
yum -y install https://www.softwarecollections.org/en/scls/rhscl/python33/epel-7-x86_64/download/rhscl-python33-epel-7-x86_64.noarch.rpm
```

## System packages

There are a number of packages that must be installed using `yum`. These can be installed like so:

```bash
yum -y --exclude=python33-mod_wsgi* install python33-* pciutils
```

---

## Python 3 Packages

To avoid file permission errors and Python version issues, use virtualenv to create an isolated environment with Python3.
The required Python 3 packages can be found in the `requirements.txt` file in the root of the test suite.
They can be installed in your virtual environment like so:

```bash
scl enable python33 bash
# Create virtual environment
virtualenv vsperfenv
cd vsperfenv
source bin/activate
pip install -r requirements.txt
```

You need to activate the virtual environment every time you start a new shell session.
To activate, simple run:

```bash
scl enable python33 bash
cd vsperfenv
source bin/activate
```

# Working Behind a Proxy

If you're behind a proxy, you'll likely want to configure this before running any of the above. For example:

```bash
export http_proxy=proxy.mycompany.com:123
export https_proxy=proxy.mycompany.com:123
```
