Install the RPM version of Indigo libs and Indigo Web Server

Get the rpm

The Indigo-rpm project contains the RPM that can be used to install an indigo server on a fedora/redhat system.

Prerequisite

Java 8 (Needed by Cassandra/DSE)

Install Oracle Java SE Runtime Environment 8 (JDK) (1.8.0_40 minimum) or OpenJDK 8. Earlier or later versions are not supported by DataStax Enterprise.

See Datastax Documentation and Download Java SE 8 from Oracle Website.

$ sudo rpm -ivh jdk-8u121-linux-x64.rpm
$ sudo alternatives --install /usr/bin/java java /usr/java/jdk1.8.0_121/bin/java 200000
$ sudo alternatives --config java

DataStax Enterprise 5.1

See Datastax Documentation

Add the DataStax Yum repository to /etc/yum.repos.d/datastax.repo:

sudo nano /etc/yum.repos.d/datastax.repo

[datastax]
name = DataStax Repo for DataStax Enterprise
baseurl=https://dsa_email_address:password@rpm.datastax.com/enterprise
enabled=1
gpgcheck=0

Install DSE 5.0.7-1

$ sudo yum install dse-full-5.0.7-1

Configure DSE 5.0.7-1

Stop DSE

$ sudo systemctl stop dse.service

Clear Cassandra logs

$ echo -n | sudo tee /var/log/cassandra/system.log

Remove cluster metadata

$ sudo rm -rf /var/lib/cassandra/*

Modify Cassandra config file

$ sudo nano /etc/dse/cassandra/cassandra.yaml

node_ip is the IP address used by Cassandra nodes to communicate with each other (In case of a single node cluster the default value should work correctly).

Values to modify:

cluster_name: 'indigo_cluster'
num_tokens: 128
seeds: "node_ip"
listen_address: node_ip
broadcast_address: node_ip

Modify DSE config file

$ sudo nano /etc/default/dse

Value to modify:

GRAPH_ENABLED=1

Restart DSE

$ sudo systemctl start dse.service

Install Indigo libs

Install dependencies

$ sudo yum install -y automake gcc gcc-c++ kernel-devel git htop iotop python-pip python-virtualenv

Install RPM

$ cd /vagrant
$ sudo rpm -ivh indigo-1.2-1.noarch.rpm

Install Indigo-web package

Install dependencies

Install Indigo lib

$ sudo yum install -y expect nginx openldap-devel

Install RPM

$ sudo rpm -ivh indigo-web-1.2-1.noarch.rpm

Create the virtual environment for the web app

As the user indigo (sudo -i -u indigo)

$ virtualenv /var/lib/indigo/web
$ ln -s /var/lib/indigo/indigo-web /var/lib/indigo/web/project

Install Indigo lib in the the virtual env

As the user indigo (sudo -i -u indigo)

$ cd /var/lib/indigo/indigo
$ /var/lib/indigo/web/bin/pip install -r requirements.txt
$ /var/lib/indigo/web/bin/python setup.py develop

Install requirements for Indigo-web in the the virtual env

As the user indigo (sudo -i -u indigo)

$ cd /var/lib/indigo/web/project
$ /var/lib/indigo/web/bin/pip install -r requirements.txt

Create the Cassandra database

As the user indigo (sudo -i -u indigo)

$ /var/lib/indigo/web/bin/iadmin create

Collect static pages (Django)

As the user indigo (sudo -i -u indigo)

$ /var/lib/indigo/web/bin/python /var/lib/indigo/web/project/manage.py collectstatic --noinput

Initialise Django database

As the user indigo (sudo -i -u indigo)

$ /var/lib/indigo/web/bin/python /var/lib/indigo/web/project/manage.py syncdb

Create default users

As the user indigo (sudo -i -u indigo)

indigo is an administrator

$ /var/lib/indigo/web/bin/iadmin mkuser indigo
$ /var/lib/indigo/web/bin/iadmin mkuser guest

Create default groups

As the user indigo (sudo -i -u indigo)

$ /var/lib/indigo/web/bin/iadmin mkgroup admins
$ /var/lib/indigo/web/bin/iadmin mkgroup guest

Add users to groups

As the user indigo (sudo -i -u indigo)

$ /var/lib/indigo/web/bin/iadmin atg admins indigo
$ /var/lib/indigo/web/bin/iadmin atg guest guest

Serve Indigo-web with gunicorn

$ cd /var/lib/indigo/web/project/
$ source /var/lib/indigo/web/bin/activate
$ gunicorn indigo_ui.wsgi

It is possible to specify the IP used to serve the web app

$ gunicorn -b 192.168.50.4 indigo_ui.wsgi

Indigo should be available at http://{node-ip}:8000

Eventually you may have to stop the firewall (or configure it)

$ sudo systemctl stop firewalld

Serve using Nginx

$ sudo mkdir /etc/nginx/sites-available
$ sudo mkdir /etc/nginx/sites-enabled
$ sudo cp conf/nginx_redhat /etc/nginx/nginx.conf
$ sudo cp conf/indigo-web.nginx /etc/nginx/sites-available/indigo_http
$ sudo ln -s /etc/nginx/sites-available/indigo_http /etc/nginx/sites-enabled/indigo_http
$ sudo systemctl restart nginx.service

Configure Indigo-web init script (systemctl)

$ sudo cp conf/indigo-web.service.redhat /etc/systemd/system/indigo-web.service
$ sudo systemctl daemon-reload
$ sudo systemctl restart indigo-web.service
