Dependencies

Database:

• Neo4J DB server >= 2.1.5 - http://neo4j.com/download/

Server:

• Python 2.7 or 3.4
• Apache Ant >= 1.9.0
• Python dependencies as described in requirements.txt

Client

• currently bundled, but listed in bower.json

For rebuilding client css from scss saource files you will need:

• sass (scss tool)

Build dependencies:

• ant
• make

Installation

Apt based systems: Debian / Ubuntu

# apt-get install \ ant \ python-pip \ ruby-sass

Generic

use pip to install all requirements

$ pip install -r requirements.txt

Use npm for javascript (client) requirements, currently for development (testing) only, all other external dependencies are part of the repository:

$ npm install

Running instructions

Running Rhizi Locally

To run Rhizi locally:

• Run neo4j locally on the default 7474 port neo4j console or neo4j server after installing neo4j: we use 2.2.1 from http://neo4j.com
• Launch run-local.sh:
  $ ./run-local.sh

Or perform the following by hand:

• Invoke the local deployment Ant target:
  ant -f ./build.ant deploy-local
• Run rhizi-server.py:
  $ cd deploy-local && python bin/rz_server.py --config-dir=etc

Command line use documentation can be viewed with: :$ python rz_server.py -h

Configuration

Rhizi configuration is currently documented in code, see src/server/rz_server.py#Config

User addition

Through the sign up page you can add users.

Changing users roles

This is possible through the src/local/rz_cli_tool as follows: ./src/local/rz_cli_tool.py --config-dir res/etc --user-db-path res/user_db.db --email alon@rhizi.local --role-add admin

Development

Build currently uses Apache Ant(http://ant.apache.org/) and make

To update the css files you need sass. To rebuild the css files issue make from the top level directory:

$ make

For dev mode(debbuging, manual file load) use ?debug=1 at end of URL: e.g. file://rhizifolder/html.index?debug=1

Client testing:

$ npm install $ karma start

Coding Conventions - Ant Scripts

• use underscore as delimiter in var name, eg: pkg_foo_bar

Coding Conventions - CSS / SCSS

• assume use of modern browsers
• indent files using 4 space characters
• apply alphabetical ordering whenever possible: selectors, directives, etc.
• use a combination of CSS classes / IDs to draw common/unique styling, eg. class=form-Foo_input-field id=email-field
• minimize use of CSS directives, remove directives which have no effect
• avoid using browser-specific CSS directives when hand-writing CSS code

Neo4J DB management

• Clean Neo4J instances are auto-initialized by the rhizi server
• to reset the DB manually: $ neo4j-shell -file res/neo4j/reset-db__clean.cypher

Running server tests

Test code makes use of Python's unittest - run by invoking them with python, or by creating a launch configuration in your IDE of choice.

Note: server test-cases do not yet support pre-run DB state validation and are likely to leave DB side-effects.

Random data generation

Taks a look at src/server-tests/test_util__rzdoc#DBO_RDG__skill_graph as a starting point for random data generation.

Installing on windows (WIP)

mingw doesn't have python support, so using mingw (I want a unix native python)

• www.cygwin.com setup-x86_64.exe
• use correct mirror (i.e. mirror.isoc.org.il)
• defaults (c:\cygwin64)
• python + gvim + vim + python-six + git + git-completion + tig + ruby + ruby-sass + make + gcc-core + autoconf + automake
• start cygwin shell
• cd to directory of install
• git clone or extract tarball
• cd rhizi
• install neo4j from neo4j.com community eddition (neo4j-community_windows_2_1_6.exe)
• install python prerequisites:
• download get-pip.py from http://pip.pypa.io/en/latest/installing.html
• $ python get-pip.py
• install JDK: java SE development Kit 8 jdk-8u31-windows-x64.exe
• install ant: winant.googlecode.com/files/winant-install-v7.exe
  • specify JDK install directory, i.e. C:\Program Files\Java\jdk1.8.0_31
• Current ant bug: /usr/bin/rhizi is translated by ant to \usr\bin\rhizi and so it fails to find rhizi.
  • solution 1: replace /usr/bin/rhizi with rhizi, it will find rhizi in PATH
  • solution 2: ?
• pip install flask
• pip install gevent-websocket
  • pip install gevent never completes setup.py stage
  • solution 1: pip install cython git+git://github.com/surfly/gevent.git#egg=gevent
  • didn't complete.

Deployment

Deployment, that is installation on a different server that has none of the development prerequisites installed, takes two forms currently:

• development mode, in which flask handles all resource serving, including client/server code, resources & fragments
• reverse proxy mode, in which a reverse proxy, eg. Apache is used to serve all static content

These modes impost a slightly different resource layout, and require the following values to be correcly set/injected:

• app.js: fragment_d_path, handled by jinja
• rhizi-server.conf: fragment_d_path
• rhizi-server.conf: template_d_path

Deployment Steps

• obtain a server configuration by either adjusting res/etc/rhizi-server.conf.example or reusing an already active one.

• the following configuration keys will likely need changing: DEBUG, SECRET_KEY, root_path, access_control, etc.

• let targetDomain be the target domain (i.e. rhizi.example.com)

• place configuration at res/production-patch-set/${targetDomain}/rhizi-server.production.conf

• use the build.ant deploy-remote target:

  • adjust targetDomain path: should point at the configuration's file dir
  • adjust remoteDeployServer to point at the target server

• use res/debian/rhizi.init to run rhizi as a system process: rz_server.py will need chmod'ing to +x

• Deploying: $ ant -v -f build.ant -DremoteDeployServer=rhizi.example.com -Drsync_module=/srv/www/rhizi.example.com deploy-remote

getting the current config file from the server:

$ targetDomain="cri.rhizi.net" $ mkdir res/production-patch-set/${targetDomain} $ scp rz-1:/etc/rhizi/rhizi-server.conf res/production-patch-set/${targetDomain}/rhizi-server.production.conf

Tools

rz-doc

This is the only way to merge a number of documents right now. Here is how:

It is installed by default to /srv/www//tools/rz-doc, lets call that rz-doc for short.

rz-doc --list-names

• will show all available documents. uses default config in /etc/rhizi/rhizi-server.conf, can be overridden with --config-dir

1. rz-doc --list-names > merge.file
2. rz-doc --merge-file merge.file --merge-target "All Documents"

creates a new doc called "All Documents" with the contents of all rzdocs in merge.file.
