Status : Draft


Melalui pip 

Install dengan pip masih gagal.

Melalui Git Repository

Ketika install requirement muncul error :

Solusi, uninstall kemudian install kembali redis dan hiredis :

sudo -H  pip uninstall redis
sudo -H  pip uninstall hiredis
sudo -H  pip install redis
sudo -H  pip install hiredis

Jalankan perintah :

fab setup_deps

Jika muncul error :

Error: Cannot find module 'findup-sync'

indico>>sudo rm node_modules/findup-sync
indico>>sudo npm install -g grunt-cli

Muncul error :

Fatal error: local() encountered an error (return code 1) while executing 'npm install'


Error ini sepertinya akibat tidak menggunakan phantojs terbaru, setelah menginstall phantomjs terbaru (2.1.1) error ini tidak terjadi. 

sudo apt-get remove --purge  phantomjs
sudo apt-get install  phantomjs

Lalu jalankan :

sudo python install

Jika ingin setup development environtment untuk indico, bisa menjalankan juga :

sudo python develop_config

Lalu :

sudo indico_initial_setup

Setelah selesai, akan ada informasi :

Indico has been installed correctly.

    indico.conf:      /opt/indico/etc/indico.conf

    BinDir:           /opt/indico/bin
    DocumentationDir: /opt/indico/doc
    ConfigurationDir: /opt/indico/etc
    HtdocsDir:        /opt/indico/htdocs

For information on how to configure Apache HTTPD, take a look at:

Please do not forget to start the Celery worker in order to use background tasks
such as event reminders and periodic cleanups. You can run it using this command:
$ indico celery worker -B

If you are running ZODB on this host:
 - Review /opt/indico/etc/zodb.conf and /opt/indico/etc/zdctl.conf to make sure everything is ok.
 - To start the database run: zdaemon -C /opt/indico/etc/zdctl.conf start

Sesudah mensetup virtual host, dan merestart apache muncul error :

Ketika diperiksa ternyata symlink nya salah. Setelah diperbaiki, Alhamdulillah, bisa, berikut adalah konfigurasi virtual host yang digunakan untuk development :

Setelah restart Apache, masih muncul error :

Sepertinya, konfigurasinya belum diisi semua.

Lengkapi dulu konfigurasinya : /opt/indico/etc/indico.conf
