Your SkyDBA team functions as virtual members of your team who know your application, data, and environment allowing them to provide a cost-effective extension to your in-house team. SkyDBAs are more than just experts that you call in when there is a crisis although they excel at that too.

SkyDBAs work in a close partnership with our customers. With a SkyDBA subscription you acquire a team of database experts available around the clock to handle not only immediate issues but to help with implementation, upgrades, indexes, capacity planning, performance tuning and more.

They provide consultative service such as:. We require a minimum of 5 years DBA experience and most of our SkyDBAs have closer to 10 years supporting complex and high pressure database environments. Users need management, backup and restore strategies need to be customized and implemented, workloads need monitoring, security needs auditing, performance needs to be optimized, the list goes on and on.

SkyDBA can be there to help with that. For SkyDBA subscribers, an on-boarding call is conducted to gather the additional information for the MariaDB SkyDBA team to document information about your application architecture and general workflows.

Once the required information has been collected, monitoring software will be updated in your environment to alert you and the SkyDBA team of issues. Certain alerts such as server availability, replication health, and others will be configured to automatically open issues in the Customer Support Portal linked from the SkySQL portal and trigger proactive responses from the SkyDBA team. In addition to assisting with day-to-day operations, SkyDBAs are consultants who can help you assess your needs and prevent issues.

This may include things like performance tuning and indexing. For example, we recently helped a customer with a very large and rapidly growing table to implement a horizontal partition and data archive strategy to resolve overall performance issues. Engineered for mission-critical applications and enterprise governance, SkySQL is focused on features that make life better for the developer, the DBA, and the operator — extending powerful enterprise features with unrivaled ease of use and first-in-class innovation.

Within our home directory we can create a project directory. This will become the working directory where we execute the ansible-playbook command and create all files for the project:. Ansible needs a list of hosts to work with. We will create a file call inventory. To begin with we will have just the single localhost listed to test our Playbook development.

We can now create a project configuration for ansible called ansible. We only need to set the inventory location for this project:. The configuration is now complete and we can now create the ansible playbook. The playbook defines the desired state of the managed system. In our case, the localhost.

We can create the file called mariadb. This means that the whitespace is significant and items at the same configuration level should be spaced the same as other sibling elements. The first task installs the database and python interface with the yum module.

Then, with the second task, we ensure the service enabled and running. We then set the mysql root user password and ensure, using the final task that remote connections are not enabled for the root account.

Ansible is an IT automation tool. It can configure systems, deploy software, and orchestrate more advanced IT tasks such as continuous deployments or zero downtime rolling updates.

It also has a strong focus on security and reliability, featuring a minimum of moving parts, usage of OpenSSH for transport with an accelerated socket mode and pull modes as alternativesand a language that is designed around auditability by humans — even those not familiar with the program source: Ansible documentation.

Ansible can help deploying MariaDB Galera Cluster in the cloud, on your enterprise servers or even on your home testing server.

For the purpose of testing I have used virtual machines deployed with Vagrantwhich allows to easily deploy new instances. Any Linux distribution can be used for the purposes of this demonstration however I will stick to Ubuntu We also forward the ports for easy local access to local port for the master, and for the slave. Ansible uses YAML as an easy markup language to define instructions.

If you have correctly created both files Vagrantfile and mariadb. Each task defined in the YAML playbook should now be played. Ansible should indicate success or errors for each configuration pass:. In the next series we will push the experiment further using the Ansible template engine and leveraging it to configure a Galera cluster automatically.

Back to Blog.Kolla-Ansible can facilitate either full or incremental backups of data hosted in MariaDB. By default, backups will be performed on the first node in your Galera cluster or on the MariaDB node itself if you just have the one. For backups to work, some reconfiguration of MariaDB is required - this is to enable appropriate permissions for the backup client, and also to create an additional database in order to store backup information.

Firstly, enable backups via globals. Once that has run successfully, you should then be able to take full and incremental backups as described below. A suggested schedule would be:. Backups are performed on your behalf on the designated database node using permissions defined during the configuration step; no password is required to invoke these commands. Owing to the way in which Mariabackup performs hot backups, there are some steps that must be performed in order to prepare your data before it can be copied into place for use by MariaDB.

This process is currently manual, but the Kolla Mariabackup image includes the tooling necessary to successfully prepare backups. Two examples are given below. For a full backup, start a new container using the Mariabackup image with the following options on the master database node:.

This starts off similar to the full backup restore procedure above, but we must apply the logs from the incremental backups first of all before doing the final preparation required prior to restore. In the example below, I have a full backup - mysqlbackup At this point the backup is prepared and ready to be copied back into place, as per the previous example.
