Team SimcovID sedang membahas model dan simulasi tentang COVID-19 di Indonesia
Update terakhir dapat dilihat di https://simcovid.github.io/
Update 20 April 2020: https://simcovid.github.io/topics/simulation_model/modelling/report/Modelling%20Update%20SimcovID%20220420.pdf
Berikut ini prosedur instalasi CAS (https://www.apereo.org/projects/cas) hanya untuk keperluan development , misal untuk pengujian fungsionalitas Single Sign On (SSO) di sebuah aplikasi, bukan untuk production.
Keterbatasan:
Prosedur:
buat VM misal di VirtualBox, ukuran disk 10 GB cukup. Setelah instalasi CAS akan memakai space 4,05 GB
Install Ubuntu 19.10 , sebaiknya versi server (http://releases.ubuntu.com/19.10/ubuntu-19.10-live-server-amd64.iso) supaya lebih kecil.
CAS memakai Java, untuk itu perlu install java development kit (download 288 MB, memakai space 800 MB)
apt install default-jdk
install git:
apt install git
clone CAS:
cd /opt
git clone https://github.com/apereo/cas-overlay-template
cd cas-overlay-template
pilih CAS versi 6.1, kemudian lakukan build
checkout 6.1
./gradlew clean build
buat keystore
./gradlew createKeystore
copy konfigurasi CAS dari /opt/cas-overlay-template/etc/cas ke /etc/cas
./gradlew copyCasConfiguration
jalankan CAS sebagai executable WAR:
./gradlew run
Akses ke situs (misal https://192.168.0.202:8443). Akan ada peringatan karena menggunakan self-signed certificate. Klik saja di “accept the risk and continue”
Browse ke situs: https://192.168.0.202:8443/cas
Selanjutnya coba login ke CAS, dengan username:casuser, password:Mellon
Jika loginlancar akan muncul tampilan:
Jika password salah akan muncul tampilan:
Menambah user & password baru:
Edit file /etc/cas/config/cas.properties, user dan password dapat ditambahkan dengan baris berikut:
cas.authn.accept.users=casuserz::Mellon,abcd::efgh, user1::123456, user2::abcdefg
Username dan password dipisahkan dengan ‘::’, antar user dipisahkan dengan koma.
Konfigurasi client agar dapat diakses dari CAS client perlu tahap-tahap berikut:
nano /opt/cas-overlay-template/build.gradle
Edit file /opt/cas-overlay-template/build.gradle, edit supaya ada bagian ini:
dependencies {
compile “org.apereo.cas:cas-server-support-json-service-registry:${casServerVersion}”
}
Kemudian build ulang CAS
./gradlew clean build
Buat file /etc/cas/services/wildcard-1000 dengan isi sebagai berikut:
{
“@class” : “org.apereo.cas.services.RegexRegisteredService”,
“serviceId” : “^(https|imaps)://.*”,
“name” : “wildcard”,
“id” : 1000,
“evaluationOrder” : 99999
}
Tambahkan baris berikut di /etc/cas/config/cas.properties:
cas.serviceRegistry.initFromJson=false
cas.serviceRegistry.json.location=file:/etc/cas/services
Pengujian dengan CAS client
Contoh konfigurasi CAS Client di Drupal 8.8.1

bundle install is needed to upgrade all gems to latest versions.
Problem: > bundle install --without development test Traceback (most recent call last): 1: from /usr/local/bin/bundle:23:in `<main>' /usr/local/bin/bundle:23:in `load': cannot load such file -- /usr/share/rubygems-integration/all/gems/bundler-1.16.1/exe/bundle (LoadError)
Solution:
Ref: https://github.com/bundler/bundler/issues/6227
Just run:
gem update --system gem uninstall bundler gem install bundler bundle install
this solution doesn’t not always work

Prosedur instalasi Redmine di Ubuntu secara umum dapat dibaca di http://www.redmine.org/projects/redmine/wiki/howto_install_redmine_on_ubuntu_step_by_step , namun untuk setiap versi Ubuntu ada kemungkina perbedaan-perbedaan kecil.
Berikut ini proses instalasi aplikasi pendukung Redmine:
apt-get update
apt-get remove cryptsetup-initramfs #optional, karena kadang-kadang kalau apt-get upgrade jadi macet di sini
apt-get upgrade
apt-get install apache2 software-properties-common ruby-rmagick mysql-server mysql-client mysql-common
apt-get install ruby-dev build-essential libmysqlclient-dev libssl-dev gcc libmysqlclient-dev
apt-get install libapache2-mod-passenger # untuk integrasi apache-passenger
apt-get install libmagickcore-dev # untuk rmagick , menghindari pesan “ERROR: Can’t install RMagick 4.0.0.” https://stackoverflow.com/questions/28324439/cant-install-rmagick-0-0-0-cant-find-magick-config
apt-get install redmine redmine-mysql
gem update
gem install bundler
edit file /etc/apache2/mods-available/passenger.conf
existing:

ditambah “PassengerDefaultUser www-data” menjadi:
PassengerDefaultUser www-data
PassengerRoot /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini PassengerDefaultRuby /usr/bin/ruby
tambahkan symlink:
ln -s /usr/share/redmine/public /var/www/html/redmine
edit file /etc/apache2/sites-available/000-default.conf , tambahkan sebagai berikut:
<Directory /var/www/html/redmine>

Tambahkan file lock untuk Gemfile
touch /usr/share/redmine/Gemfile.lock
chown www-data:www-data /usr/share/redmine/Gemfile.lock
Restart Apache supaya konfigurasi dibaca ulang:
service apache2 restart

Artikel ini adalah adaptasi dari prosedur instalasi di https://github.com/Cloud-CV/EvalAI
apt-get install openssh-server
apt-get install net-tools
Instalasi software dependencies:
apt-get install python2.7
apt-get install git
apt-get install postgresql# Success. You can now start the database server using:
# /usr/lib/postgresql/9.6/bin/pg_ctl -D /var/lib/postgresql/9.6/main -l logfile startapt-get install rabbitmq-server
apt-get install virtualenv
apt-get install python-psycopg2 (thanks to https://stackoverflow.com/questions/28253681/you-need-to-install-postgresql-server-dev-x-y-for-building-a-server-side-extensi)
apt-get install libpq-dev
apt-get install python-dev
apt-get install build-essential
# clone the EvalAI code
git clone https://github.com/Cloud-CV/EvalAI.git evalai
# Create a python virtual environment and install python dependencies.
cd evalai
virtualenv venv
source venv/bin/activate # run this command everytime before working on project
pip install -r requirements/dev.txt
Proses sampai tahap ini berhasil, selanjutnya masih perlu diujicoba:
cp settings/dev.sample.py settings/dev.py
Use your postgres username and password for fields USER and PASSWORD in dev.py file.
Create an empty postgres database and run database migration.
sudo -i -u (username)
createdb evalai
python manage.py migrate –settings=settings.dev
Seed the database with some fake data to work with.
python manage.py seed –settings=settings.dev
This command also creates a superuser(admin), a host user and a participant user with following credentials.
SUPERUSER- username: admin password: password
HOST USER- username: host password: password
PARTICIPANT USER- username: participant password: password
That’s it. Now you can run development server at http://127.0.0.1:8000 (for serving backend)
python manage.py runserver –settings=settings.dev
Open a new terminal window with node(6.9.2) and ruby(gem) installed on your machine and type
npm install
Install bower(1.8.0) globally by running:
npm install -g bower
Now install the bower dependencies by running:
bower install
If you running npm install behind a proxy server, use
npm config set proxy http://proxy:port
Now to connect to dev server at http://127.0.0.1:8888 (for serving frontend)
gulp dev:runserver
That’s it, Open web browser and hit the url http://127.0.0.1:8888.
(Optional) If you want to see the whole game into play, then start the RabbitMQ worker in a new terminal window using the following command that consumes the submissions done for every challenge:
python scripts/workers/submission_worker.py
