Description

This is a template for deploying a LAMP stack on a single Linux server. This template is leveraging ansible with a chef-solo wrapper to setup the server.

Requirements

  • A Heat provider that supports the Rackspace OS::Heat::ChefSolo plugin.
  • 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.

Example Usage

Here is an example of how to deploy this template using the python-heatclient:

heat --os-username <OS-USERNAME> --os-password <OS-PASSWORD> --os-tenant-id \
  <TENANT-ID> --os-auth-url https://identity.api.rackspacecloud.com/v2.0/ \
  stack-create LAMP-Stack -f lamp.yaml -P flavor="4 GB Performance"
  • For UK customers, use https://lon.identity.api.rackspacecloud.com/v2.0/ as the --os-auth-url.

Optionally, set environmental variables to avoid needing to provide these values every time a call is made:

export OS_USERNAME=<USERNAME>
export OS_PASSWORD=<PASSWORD>
export OS_TENANT_ID=<TENANT-ID>
export OS_AUTH_URL=<AUTH-URL>

Parameters

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

  • server_hostname: Sets the hostname of the server. (Default: web)
  • image: Operating system to install (Default: CentOS 6.5 (PVHVM))
  • flavor: Cloud server size to use. (Default: 1 GB Performance)
  • phpmyadmin_user: User name for the first factor of logging into phpMyAdmin. (Default: serverinfo)
  • kitchen: URL for the kitchen to clone with git. The Chef Solo run will copy all files in this repo into the kitchen for the chef run. (Default: https://github.com/rillip3/ChefAnsibleWrapper/)
  • chef_version: Chef client version to install for the chef run. (Default: 11.12.8)

Outputs

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

  • private_key: SSH private that can be used to login as root to the server.
  • server_ip: Public IP address of the cloud server
  • phpmyadmin_url: URL to the phpMyAdmin installation.
  • phpmyadmin_user: Username for the first factor of authentication for phpMyAdmin
  • phpmyadmin_password: Password for the first factor of authentication for phpMyAdmin
  • mysql_root_password: MySQL Root Password

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.

Stack Details

Getting Started

This deployment is intended for small workloads, such as a site in development. For a larger work load, consider using the PHP Application Deployment instead, as it will provide a much better setup for scaling production workloads.

What is provided

This deployment configures a Cloud Server running Apache, MySQL, PHP, and phpMyAdmin. A simple firewall rule set is configured allowing access to Apache and SSH.

Logging in via SSH

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.

Details of Your Setup

Apache v2.2 is installed on all Red Hat Enterprise Linux and CentOS distributions. Ubuntu 14.04 comes with Apache 2.4. Other Ubuntu versions come with 2.2.

MySQL v5.5 is installed on Ubuntu 12.04, 14.04, Red Hat Enterprise Linux 6.5 and CentOS v6.5. MySQL v5.1 is installed on Ubuntu 10.04. The MySQL root password is recorded in root's home directory in the file .my.cnf and in the View Generated Passwords dialog. Daily database backups are taken using Holland. A rotating seven days of database dumps are stored in /var/lib/mysqlbackup.

PHP is installed at v5.3 on Ubuntu 12.04, v5.5 on Ubuntu 14.04 and v5.4 on Red Hat Enterprise Linux and CentOS.

phpMyAdmin is available via HTTP at /phpmyadmin. Apache is configured to require HTTP basic authentication. Log in as the user specified when deploying (the default is admin) with the password displayed in the View Generated Passwords dialog. You may then login using MySQL login credentials which are also available in the View Generated Passwords dialog.

Contributing

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