This is a Heat template to deploy multiple Linux server running Magento Community Edition.

• A Heat provider that supports the following:
  • OS::Heat::ChefSolo
  • OS::Heat::RandomString
  • Rackspace::Cloud::LoadBalancer
  • OS::Heat::ResourceGroup
  • Rackspace::Cloud::Server
  • OS::Nova::KeyPair
• An OpenStack username, password, and tenant id.
• python-heatclient >= v0.2.8:

pip install python-heatclient

We recommend installing the client within a Python virtual environment.

Parameters can be replaced with your own values when standing up a stack. Use the -P flag to specify a custom parameter.

• domain: Domain to be used with the Magento store (Default: example.com)

Once a stack comes online, use heat output-list to see all available outputs. Use heat output-show <OUTPUT NAME> to get the value of a specific output.

• private_key: SSH Private Key
• load_balancer_ip: Load Balancer IP
• admin_password: Admin Password
• admin_user: Admin User
• mysql_root_password: MySQL Root Password
• admin_url: Admin URL

For multi-line values, the response will come in an escaped form. To get rid of the escapes, use echo -e '<STRING>' > file.txt. For vim users, a substitution can be done within a file using %s/\\n/\r/g.

If you're new to Magento Community Edition, the Magento User Guide will step you through the process of configuring and managing your store. This guide is free, but does require you to provide a valid email address to receive it.

The Magento Forum provides a place to get answers to both simple and advanced questions regarding configuration and management of Magento Community Edition.

To login, go to the URL listed above in a browser. If your DNS is not pointing to this installation, you can add a line in your hosts file to point your domain to the IP of this Cloud Server. Once you've done this, restart your browser and navigate to the site. The backend can be accessed by adding '/admin' to the end of the URL, and you can login with the credentials provided above.

The private key provided in the passwords section can be used to login as root via SSH. We have an article on how to use these keys with Mac OS X and Linux as well as Windows using PuTTY.

This deployment was stood up using chef-solo. Once the deployment is up, chef will not run again, so it is safe to modify configurations.

A system user named 'magento' has been created. This user does not have a password set, so if you wish to use the account, a password will need to be set. This account is the system user for PHP-FPM, so deletion of this user will take eCommerce site down.

Nginx is used as the web server and listens on port 80 and 443 to handle web traffic. The configuration for your site can be found in /etc/nginx/sites-enabled. There will be a default site configuration, and a seperate one for SSL traffic. Magento itself is installed in /var/www/vhosts. You will find a directory with the name of website you entered as a part of this deployment. The SSL certificates used are self signed and were generated when this deployment was created. You can replace the private key and certificate by overwriting the ones in /etc/nginx/ssl.

PHP-FPM is used to handle evaluation of all PHP-based pages. The configuration for this installation is in /etc/php5/fpm/pools/magento.conf. By default, PHP-FPM is running as the 'magento' user, listens on port 9001.

Object and session caching are handled by Memcached. Memcache helps performance by storing data in memory for faster responses to clients. These caches help lessen the number of queries required to the database. There are two seperate instances of Memcached running to ensure session and object caching are handled seperately. The session cache is listening on port 11211, and is set as a 512MB cache. The object cache is listening on port 11212, and it is set as a 1.5GB cache. The configuration files are memcached_sessions.conf and memcached_backend.conf in /etc on the database server.

MySQL 5.5 is installed as the database backend. All configuration with Magento has been handled as a part of the setup. The MySQL root password is provided as a part of this deployment. If you lose or forget the password, it can also be found in /root/.my.cnf.

MySQL backups are performed nightly by Holland. Backups can be found in /var/lib/mysqlbackup on the Database server

There are thousands of plugins that have been developed for Magento by the developer community. Magento Connect provides an easy way to discover popular plugins that other users have found to be helpful. Not all plugins are free, and we recommend only installing the plugins that you need.

There is not an automatic way to add additional nodes to this deployment. This deployment is meant for lower traffic or testing scenarios.

There are substantial changes still happening within the OpenStack Heat project. Template contribution guidelines will be drafted in the near future.
