Quick Start Guide

The following Description applies to Ubuntu or similar.

Clone repository

Clone this repository and navigate into

$ git clone https://gitlab.cip.ifi.lmu.de/jost/UniWorX.git && cd UniWorX

LDAP

install:

$ sudo apt-get install slapd ldap-utils

PostgreSQL

install:

$ sudo apt-get install postgresql

switch to user postgres (got created during installation):

$ sudo -i -u postgres

add db user uniworx:

$ createuser --interactive

you'll get a prompt:

Enter name of role to add:` - uniworx
Shall the new role be a superuser? (y/n)` - [not exactly sure. Guess not?]
Password: uniworx
...

create database uniworx:

$ createdb uniworx

after you added the database switch back to your own user with Ctrl + D.

to access the database as user uniworx you now need to add a new linux-user called uniworx. when you get asked for a password enter uniworx.

$ sudo adduser uniworx

log-in as new user uniworx:

$ sudo -i -u uniworx

you can now use

$ psql uniworx

to execute SQL-commands and such.

stack

Install with:

$ curl -sSL https://get.haskellstack.org/ | sh

setup stack and install dependencies:

$ stack setup

During this step or the next you might get an error that says something about missing C libraries for ldap and lber. You can install these using

$ sudo apt-get install libsasl2-dev libldap2-dev

If you get an error that says You need to install postgresql-server-dev-X.Y for building a server-side extension or libpq-dev for building a client-side application. Go ahead an install libpq-dev with

$ sudo apt-get install libpq-dev

Other packages you might need to install during this process:

$ sudo apt-get install pkg-config
sudo apt-get install libsodium-dev

Build the app:

$ stack build

This might take a few minutes if not hours... be prepared.

install yesod:

$ stack install yesod-bin --install-ghc

Add Dumy-Data and run the app

After building the app you can prepare the database and add some dummy data:

$ ./db.sh -f

Run the app:

$ ./start.sh
...
Devel application launched: http://localhost:3000

If you followed the steps above you should now be able to login as user Gregor Kleen using LDAP:g.kleen@ifi.lmu.de as dummy login.

--Zeige Tabellen \dt

--Zeige Tabellen Inhalt: TABLE "user"; -- Die Anführungszeichen können manchmal weggelassen werden, aber -- bei user sind sie notwendig, da es auch Schlüsselwort in sql ist.

--Lösche Tabelle "course" und alle davon abhängigen: DROP TABLE "course" CASCADE;

-- UserId 5 zum Lecturer in SchoolId 1 machen (27 ist laufende Nummer) INSERT INTO "user_lecturer" (id,"user","school") VALUES (27,5,1);
