Setup ODOO on EC2 & RDS (Insecure)
_______________________________________

 

Go to https://www.odoo.com and make sure you understand the needs for an ERP system at your startup. I would advice that you evaluate the pros & cons for using an ERP before jumping into this bureaucratic complication.

Security is prime and make sure you realize that I have not covered any aspect of securing the instance or the application here.
1. Intallation pre-requisites

a. Initialize a RDS PostgreSql service on AWS.

b. Initialize an EC2 instance with Amazon Linux in the same security group as RDS

yum install git libtool zlib devel automake pkgconfig gcc c++ curl make gcc-c++ libxml2-devel rsync
yum install openldap-devel libjpeg-devel python-devel vim
yum -y install babel libxslt-python pyparsing python-dateutil python-decorator python-docutils python-feedparser python-imaging python-jinja2 python-ldap python-lxml python-mako python-mock python-openid python-passlib python-psutil python-psycopg2 python-reportlab python-requests python-simplejson python-unittest2 python-vobject python-werkzeug python-yaml pytz
yum install icu xorg-x11-fonts-75dpi freetype freetype-devel 

> Setup Node
yum install nodejs npm
npm install -g less less-plugin-clean-css
ln -s /usr/local/bin/lessc /usr/bin/lessc
ln -s /usr/bin/nodejs /usr/bin/node

> CentOS 6
yum localinstall http://yum.postgresql.org/9.3/redhat/rhel-6-x86_64/pgdg-centos93-9.3-1.noarch.rpm
wget https://bitbucket.org/wkhtmltopdf/wkhtmltopdf/downloads/wkhtmltox-0.13.0-alpha-7b36694_linux-centos6-amd64.rpm
rpm -ivh wkhtmltox-0.13.0-alpha-7b36694_linux-centos6-amd64.rpm

> CentOS 7
yum localinstall https://yum.postgresql.org/9.3/redhat/rhel-7-x86_64/pgdg-redhat93-9.3-3.noarch.rpm
wget http://download.gna.org/wkhtmltopdf/0.12/0.12.2.1/wkhtmltox-0.12.2.1_linux-centos7-amd64.rpm
rpm -Uvh wkhtmltox-0.12.2.1_linux-centos7-amd64.rpm

yum install postgresql93-contrib postgresql93-devel postgresql93-plpython27
Now lets get the odoo source on the machine to start the setup
git clone https://github.com/odoo/odoo.git
Go to your odoo directory and install the python packages
easy_install -U setuptools
easy_install pip
pip install -r requirements.txt

2. Create a config file openerp-server.conf with the below content

[options]
; This is the password that allows database operations:
; admin_passwd = admin
db_host = admindb.xxxxxxx.us-west-2.rds.amazonaws.com
db_port = 5432
db_user = admin
db_password = admin123
addons_path = /usr/lib/python2.7/dist-packages/openerp/addons
logfile = /tmp/odoo-server.log
xmlrpc_port = 8069

Setup a RDS with postgres database server

psql -h admindb.xxxxxxx.us-west-2.rds.amazonaws.com -U admin admindb

CREATE USER admin WITH PASSWORD 'admin123';
ALTER USER admin CREATEDB;

3. Run the server with the configurations

chown -R ec2-user odoo 
./odoo-bin --addons-path=addons --config=openerp-server.conf

4. Configure the EC2 Instance

a.) IP routing on the instance. Not secure, but will provide the basic routing to start your system.

iptables -t nat -A OUTPUT -p tcp -d ec2-xxx-xxx-xxx-xxx.us-west-2.compute.amazonaws.com --dport 80 -j REDIRECT --to-port 8069
iptables -t nat -I PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-ports 8069
Make sure you verify the iptables. 
sudo iptables -t nat -L -v

Chain PREROUTING (policy ACCEPT)
target prot opt source destination
REDIRECT tcp -- anywhere anywhere tcp dpt:http redir ports 8069
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
REDIRECT tcp -- anywhere ip-xxx-xxx-xxx-xxx.us-west-2.compute.internal tcp dpt:http redir ports 8069
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination

 

b.) Security group config for port 80. Add exception for incoming HTTP traffic
5. Run the ODOO server as a service

echo "Killing any previous instance of odoo"
ps ax | grep odoo | grep -v grep | awk '{print $1}' | xargs sudo kill
echo "Starting the Odoo server"
nohup ./odoo-bin --addons-path=addons --config=openerp-server.conf -d oodb -u all &> /dev/null & disown
echo "Conf : ~/odoo/odoo/openerp-server.conf"
echo "Log : tail -f /tmp/odoo-server.log"

6. Login as admin / admin
http://ec2-xxx-xxx-xxx-xxx.us-west-2.compute.amazonaws.com
