This software is targetted first for Linux CentOS 7 (+ Fedora and Ubuntu), but also for Mac OS X and Windows.

All these systems should run Python 3 (3.5+)

Pyros has been tested on these platforms:

* CentOS 7.1 (with Python 3.4)

* Linux Mint 17.2 ( == Ubuntu 14.04.3) (with Python 3.5)

* Ubuntu 16.04 (with python 3.5.2)

* Mac OS 10.11.6 (with Python 3.5)

* Windows 10 (with Python 3.5)

h2. %{margin-left:0px; font-weight:bold; font-size:25px;  display:block; color:red;}I - GET THE PYROS SOFTWARE%

h3. A. Authenticate to the gitlab

In order to get this software, you must first authenticate on the IRAP gitlab https://gitlab.irap.omp.eu/epallier/pyros

For this, just go to https://gitlab.irap.omp.eu/epallier/pyros

and either sign in with your LDAP account (if you are from IRAP),

or register via the "Sign up" form.

---

h3. B. Software structure

See [[Project_structure|Project Structure]] page.

h3. C. Browse the code (from gitlab)

https://gitlab.irap.omp.eu/epallier/pyros/tree/master

---

h3. D. Get the software

* *STATIC VERSION (Non developers) : Download a static version (not synchronized) :*

Go to https://gitlab.irap.omp.eu/epallier/pyros/tree/master

Click on "Download zip" on the up right hand corner.

Double-click on it to unzip it.

You should get a "pyros.git" folder.

In this documentation, this software folder will be referenced as "PYROS".

(you can rename "pyros.git" as "PYROS" if you want : "mv pyros.git PYROS")

* *DYNAMIC VERSION (Developers) : Get a dynamic version (synchronized) :*

_Windows users : you first need to get the GIT software (see below, section E)_

By getting the software from git, you will get a dynamically synchronized version,

which means that you will be able to update your version as soon as a new version is available

(with the command : "git pull").

_From Eclipse : See below, section "NOTES FOR ECLIPSE USERS"_

From the terminal :

<pre>

git clone https://gitlab.irap.omp.eu/epallier/pyros.git PYROS

</pre>

_(or also : git clone git@gitlab.irap.omp.eu:epallier/pyros.git PYROS)_

If you ever get this error message :

<pre>

fatal: unable to access 'https://gitlab.irap.omp.eu/epallier/pyros.git/': Peer's certificate issuer has been marked as not trusted by the user.

</pre>

Then, type this command (and then run again the git clone command):

<pre>

$ git config --global http.sslVerify false

</pre>

(Also, the first time you get the project, it will ask you for a login and password)

This creates a PYROS/ folder containing the project (with a .git/ subfolder for synchronization with the git repository)

---

h3. E. For WINDOWS users

 * Download git at https://git-scm.com/download/win

 * Run setup (keep default configurations)

 * Once installed, open cmd

<pre>

$ git config --global http.sslVerify false

</pre>

You can now use your git from the cmd or the graphic client !

h2. %{margin-left:0px; font-weight:bold; font-size:25px;  display:block; color:red;}II - INSTALLATION OF PREREQUISITES%

Pyros needs some prerequisites : 

* Python 3.5+

* RabbitMQ

* [optional] a Mysql Database server (but you can use Sqlite instead, with no installation)

---

h3. A. Install Python3 (3.5+) + pip

@todo: remplacer virtualenv par le module python "venv" (utilisation: python3 -m venv nom_du_venv) : https://docs.python.org/3/library/venv.html

_If Python 3 is already installed on your computer, skip this section_

 * Linux (CentOS 7.1, main target): (python35 not yet available as rpm)

<pre>

$ sudo yum update yum

$ sudo yum update kernel

$ sudo yum update

$ sudo yum install python34

$ python3.4 -V

Python 3.4.3

$ sudo yum install python34-devel

(needed for python package mysqlclient)

$ sudo yum update python-setuptools

$ easy_install --version 

setuptools 0.9.8

$ sudo easy_install pip

$ pip --version

pip 8.1.1 from /usr/lib/python2.7/site-packages/pip-8.1.1-py2.7.egg (python 2.7)

$ sudo pip install --upgrade pip

((

NO MORE NECESSARY:

$ sudo pip install --upgrade virtualenv

$ virtualenv --version

15.0.1

))

Necessary for "lxml" python package:

$ sudo yum install libxml2 libxml2-devel

$ sudo yum install libxslt libxslt-devel

</pre>

 * Linux (Ubuntu) :

<pre>

$ sudo add-apt-repository ppa:fkrull/deadsnakes

$ sudo apt-get update

$ sudo apt-get install python3.5

$ sudo apt-get install python3.5-dev

(needed for python package mysqlclient && lxml)

$ sudo apt-get install libxml2-dev

$ sudo apt-get install libxslt-dev

$ sudo apt-get install python-pip

$ sudo apt-get install python-lxml

((

NO MORE NECESSARY

$ sudo pip install --upgrade virtualenv

))

</pre>

 * Mac OS X :

  * From binary (Mac OS native application)

(TODO:)

  * From MacPort

   * a) install macport

cf https://www.macports.org/install.php

   * b) install the "port" python36

<pre>

$ sudo port install python36

$ sudo port select --set python3 python36

$ sudo port install py36-readline

$ sudo port install py36-pip

$ port select --set pip pip36

</pre>

 * Windows (tested with Windows 7 & 10) :

<pre>

Go to https://www.python.org/downloads/windows/ , choose the wanted version

On the wanted version’s page, download Windows x86 executable installer

Run the executable

    * On the first page, check "Add python3.5 to PATH"

    * Choose "Install now" option

Open cmd (windows + R, cmd) :

 $ python -m pip install --upgrade pip

((

NO MORE NECESSARY

 $ pip install virtualenv

))

</pre>

---

h3. B. Install a database server (only if necessary)

_If the MySql database server is already installed on your computer, skip this section_

By default, Pyros uses Mysql, but this implies that you have to install the Mysql database server...

Thus, to make things easier, avoid Mysql installation by using Sqlite instead as the database server (which will need no installation at all) :

=> *For this, just edit the file PYROS/src/pyros/settings.py and set MYSQL variable to False, and that's it. You can go to next section*

Now, if you really want to use Mysql (which is the default), you will need to install it (only if not already installed), so keep reading.

_(Skip this if you are using Sqlite instead of MySql)_

 * Linux Ubuntu

<pre>

First, update your system:

$ sudo apt-get update

$ sudo apt-get install mysql-server

$ sudo apt-get install mysql-client

$ sudo apt-get install libmysqlclient-dev

(needed for python package mysqlclient)

</pre>

 * Linux CentOS : cf https://www.howtoforge.com/apache_php_mysql_on_centos_7_lamp#-installing-mysql-

<pre>

First, update your system:

$ sudo yum update yum

$ sudo yum update kernel

$ sudo yum update

$ sudo yum install mariadb-server 

$ sudo yum install mariadb

$ sudo yum install mariadb-devel

(needed for python package mysqlclient)

$ sudo systemctl start mariadb.service

$ sudo systemctl enable mariadb.service

=> Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

$ sudo mysql_secure_installation

</pre>

 * Mac OS X

Install XAMPP

(but you could also use the pre-installed Mac OS MySql, or install MySql from macport)

cf https://www.apachefriends.org/fr/index.html

 * Windows (tested with Windows 7 & 10)

<pre>

Download and install the newest version on https://dev.mysql.com/downloads/installer/

Once installed, launch MySQL Installer. Clic on 'Add...' on the right.

In MySQLServers section, choose the newest, then clic on next.

Install and configure the server (just follow the installation guide).

Then launch mysql (via the Windows menu).

</pre>

---

h3. C. Install RabbitMQ

RabbitMQ is a message queue server used by Celery to handle tasks queues.

It uses the amqp protocol to manage queue messages.

 * Ubuntu (the server is automatically started) :

<pre>

$ sudo apt-get install rabbitmq-server

Get status:

$ sudo invoke-rc.d rabbitmq-server status

Stop:

$ sudo invoke-rc.d rabbitmq-server stop

Start:

$ sudo invoke-rc.d rabbitmq-server start

</pre>

 * CentOS :

<pre>

$ sudo yum install rabbitmq-server

Installation :

 rabbitmq-server                                                           noarch                          3.3.5-17.el7

Installation pour dépendances :

 erlang-asn1                                                               x86_64                          R16B-03.16.el7

Get status:

(CentOS7) $ sudo rabbitmqctl status

(older CentOS) $ sudo /sbin/service rabbitmq-server status

Stop:

(CentOS7) $ sudo systemctl stop rabbitmq-server

(older CentOS) $ sudo /sbin/service rabbitmq-server stop

Start:

(CentOS7) $ sudo systemctl start rabbitmq-server

(older CentOS) $ sudo /sbin/service rabbitmq-server start

</pre>

 * MacOS :

<pre>

With MacPort:

$ sudo port install rabbitmq-server

--->  Installing erlang @18.2.1_1+hipe+ssl

...

--->  Installing rabbitmq-server @3.5.7_0

--->  Activating rabbitmq-server @3.5.7_0

...

To start rabbitmq : 

$ sudo rabbitmq-server

Get status:

$ sudo rabbitmqctl status

To stop rabbitmq : 

$ sudo rabbitmqctl stop

</pre>

 * Windows :

  * Take the wanted Erlang version at http://www.erlang.org/downloads and install it (required)

  * Take the wanted RabbitMQ version at https://www.rabbitmq.com/install-windows.html and install it. Then the server will run automatically

h2. %{margin-left:0px; font-weight:bold; font-size:25px;  display:block; color:red;}III - INSTALLATION OF NEEDED PYTHON PACKAGES%

h3. A. Install all the needed python packages and the PyROS database (within a Python virtual environment)

---

*@todo: remplacer virtualenv par le module python "venv" (utilisation: python3 -m venv nom_du_venv) : https://docs.python.org/3/library/venv.html*

Eviter l'installation de virtualenv car ca oblige a executer le script install.py avec sudo !!!*

=> en faire plutot un pré-requis (comme python3 et mysql).

=> ou bien essayer cette nouvelle syntaxe (qui remplace avantageusement virtualenv) :

  python3 -m venv venv_py3_pyros

---

Go into the PYROS/install/ folder and Run the install.py script with the parameter install.

(You will be prompted to enter a username, an email, and a password for the superuser)

* Mac, Linux and Windows:

<pre>

python3 install.py install

</pre>

*TODO: update "create user if exists" => does not work with mysql 5.6 (only with 5.7)*

NB: you might need to drop your pyros database (and pyros_test ?) before running the install script (if migrations are too big)

_If something goes wrong, install manually each package (see section "MANUAL INSTALLATION OF PYTHON PACKAGES, ONE BY ONE")_

---

h3. B. Install the Comet python package 

Latest info on this package : http://comet.transientskp.org/en/stable/

Comet is needed as a broker to receive and send VOEvents (https://github.com/jdswinbank/Comet/tree/py3)

*You MUST have your virtualenv activated (source venv_py3_pyros/bin/activate in your 'private/' directory)*

Documentation is available here : http://comet.readthedocs.io/en/stable/installation.html

(see also http://voevent.readthedocs.io/en/latest/setup.html)

1) Essayer d'abord la méthode automatique (avec pip) :

$ source private/venv_py3_pyros/bin/activate

$ pip install comet

2) Si ça ne marche pas, essayer la méthode manuelle (download puis install) :

* Ubuntu :

<pre>

# You can do this anywhere on your computer

$ git clone https://github.com/jdswinbank/Comet.git

$ cd Comet

$ (sudo ?) python setup.py install

$ sudo apt-get install python-lxml

</pre>

* MacOS :

<pre>

Idem Ubuntu

</pre>

* Windows :

<pre>

TODO:

</pre>

3) Test Comet

$ twistd comet --help

$ trial comet

All tests should pass

---

h3. C. (Eclipse only) Set the Python3 virtual environment as the project interpreter

See below, in section "NOTES FOR ECLIPSE USERS"

---

h2. %{margin-left:0px; font-weight:bold; font-size:25px;  display:block; color:red;}IV - TEST%

(Tests are classes declared in all apps' test.py file. The test classes inherit from django.test.TestCase)

You can run the tests suite, just to be sure that the software is well installed.

h3. From Terminal

<pre>

$ cd PYROS/

Be sure that at least unit tests pass:

$ python3 pyros.py unittest

If unit tests pass, then run ALL tests:

$ python3 pyros.py test_all

NB: if tests do not pass, be sure that Rabbitmq is launched:

To start rabbitmq on MacOS : 

$ sudo rabbitmq-server

</pre>

h3. From Eclipse

Right-clic on the project / Django / Run Django tests

(for more information, see below, in section "NOTES FOR ECLIPSE USERS")

h3. Custom commands

$ [./manage.py] test app.tests                           # Run tests for the application 'app'

$ [./manage.py] test app.tests.ModelTests                # Run test methods declared in the class app.tests.ModelTests

$ [./manage.py] test app.tests.ModelTests.test_method    # Only run the method test_method declared in app.tests.ModelTests

---

---

h2. %{margin-left:0px; font-weight:bold; font-size:25px;  display:block; color:red;}V - RUN%

Before launching Pyros, check that all the pre-requisites are running :

 * RabbitMQ: 

<pre>

$ systemctl status rabbitmq-server

If inactive, start it:

$ sudo systemctl start rabbitmq-server

(To stop it, use "stop" instead of "start")

</pre>

 * Mysql (only if you are not using Sqlite):

<pre>

$ systemctl status mysqld

If inactive, start it:

$ sudo systemctl start mysqld

(To stop it, use "stop" instead of "start")

</pre>

* From the terminal

<pre>

$ cd PYROS/

$ python3 pyros.py start

(To check that this service is actually running, type "$ netstat -an |grep 8000" and you should get "tcp        0      0 127.0.0.1:8000          0.0.0.0:*               LISTEN")

(Use instead "python manage.py runserver YOUR_IP_ADDRESS:8000" if you want to access the website from another pc with http://YOUR_IP_ADDRESS:8000) (from within a virtual env, and from src/)

</pre>

Now, go to "http://localhost:8000/admin" in your browser

(and login as "pyros" with the password 'DjangoPyros')

(Ctrl-c to stop)

*Follow these steps only if the previous guided and nearly automatic installation did not work for you*

h3. (Only if using Mysql) Create the database "pyros" and the pyros user

Only if you are using Mysql, you need to create an empty database "pyros"

(which will be filled automatically by django)

<pre>

$ mysql -u root -p

(enter your root password)

$ mysql> create database if not exists pyros;

</pre>

The user creation depends on your MySQL version :

 * 5.7 and above :

<pre>

$ mysql> DROP USER IF EXISTS pyros;

$ mysql> CREATE USER 'pyros' IDENTIFIED BY 'DjangoPyros';

$ mysql> GRANT ALL PRIVILEGES ON pyros.* TO pyros;

</pre>

 * under 5.7 :

<pre>

$ mysql> GRANT USAGE ON *.* TO 'pyros';

$ mysql> DROP USER 'pyros';

$ mysql> CREATE USER 'pyros' IDENTIFIED BY 'DjangoPyros';

$ mysql> GRANT ALL PRIVILEGES ON pyros.* TO pyros;

</pre>

If none of these solution work, check on the internet to create a user named pyros with the password DjangoPyros.

h3. Create a Python3 virtual environment dedicated to the project (inside the project folder)

<pre>

$ mkdir private/

$ cd private/

$ which python3.5 ("where python" for windows)
