In the CMS Open-Source galaxy, WordPress is the most used in term of community, available features and user adoption. The Automattic compagny, which develop and distribute Wordpress, provides a SaaS offer allowing a user to create its blog in few minutes. However, those who experiments know that limits can be easily found by the wordpress.com hosting capabilities.
Today, Cloudwatt provides the necessary toolset to start your Wordpress instance in a few minutes and to become its master.
The deployement base is an Ubuntu xenial instance. The Apache and MariaDB servers are deployed on a single instance.
… Good! Go to the Apps page on the Cloudwatt website, choose the apps, press DEPLOY and follow the simple steps… 2 minutes later, a green button appears… ACCESS: you have your Wordpress!.
Yes ! Using the console, you can deploy a Wordpress server:
The stack will be automatically created (you can see its progress by clicking on its name). When all its modules will become “green”, the creation will be completed. Then you can go on the “Instances” menu to discover the flotting IP value that has been automatically generated. Now, just run this IP adress in your browser and enjoy !
It is (already) FINISH !
If you like only the command line, you can go directly to the “CLI launch” version by clicking this link
The configuration of the database is in /data/wordpress/wp-config.php file.
The goal of this tutorial is to accelarate your start. At this point you are the master of the stack.
You have a SSH access point on your virtual machine thru the flotting IP and your private keypair (default user name cloud).
The interesting entry access points are:
/data/wordpress : Wordpress installation repository./data/mysql : Mariadb nodes datadir is a cinder volume.Per default, the script is proposing a deployement on an instance type “Small” (s1.cw.small-1). Instances are charged by the minute and capped at their monthly price (you can find more details on the Tarifs page on the Cloudwatt website). Obviously, you can adjust the stack parameters, particularly its defaut size.
If you do not like command lines, you can go directly to the “run it thru the console” section by clicking here
Once you have cloned the github, you will find in the bundle-xenial-wordpress/ repository:
bundle-xenial-wordpress.heat.yml : HEAT orchestration template. It will be use to deploy the necessary infrastructure.stack-start.sh : Stack launching script. This is a small script that will save you some copy-paste.stack-get-url.sh : Flotting IP recovery script.Have your Cloudwatt credentials in hand and click HERE. If you are not logged in yet, you will go thru the authentication screen then the script download will start. Thanks to it, you will be able to initiate the shell acccesses towards the Cloudwatt APIs.
Source the downloaded file in your shell. Your password will be requested.
$ source COMPUTE-[...]-openrc.sh
Please enter your OpenStack Password:
Once this done, the Openstack command line tools can interact with your Cloudwatt user account.
With the bundle-xenial-wordpress.heat.yml file, you will find at the top a section named parameters. The sole mandatory parameter to adjust is the one called keypair_name. Its default value must contain a valid keypair with regards to your Cloudwatt user account. This is within this same file that you can adjust the instance size by playing with the flavor parameter.

+--------------------------------------+------------+--------------------+----------------------+
Last, wait 5 minutes until the deployement been completed.
At each new deployement of the stack, a password is generated directly in the /data/wordpress/config-default.php configuration file.
Once all of this done, you can run the stack-get-url.sh script.
./stack-get-url.sh Wordpress
Wordpress 82.40.34.249
It will gather the assigned flotting IP of your stack. You can then paste this IP in your favorite browser and start to configure your Wordpress instance.
The start-stack.sh script is taking care of running the API necessary requests to:
Have fun. Hack in peace.
