According to Forrester, a DBA in a large enterprise manages between 8 and 275 databases, with the industry average being 40 databases to a DBA. Larger databases usually require extra effort around tuning, backup, recovery and upgrade. Cloud, as well as automation and management tools can help improve the number of databases managed by one DBA.
With that background, we were pretty excited to introduce support for management of single-instance MySQL and MariaDB databases in ClusterControl 1.2.6. The majority, if not all of the cluster users out there, use single-instance or master-slave replicated setups along their mission-critical clusters. So today, it is possible to manage an entire MySQL/MariaDB environment from one interface.
Ok, so what about Nagios or Zabbix? Unless Nagios is deploying your instances, scaling them, recovering them if they fail, taking backups, upgrading them to newer versions, telling you about slow running queries or suboptimal configuration parameters, we’d argue that you probably ought to look into a management tool.
In today’s blog post, we’ll show you how you set that up.
Our setup consists of MySQL servers running different versions (5.1, 5.5 and 5.6) and on different hosts:
Installing ClusterControl
Deploy ClusterControl on a dedicated host (192.168.197.100) using these simple steps:
$ wget http://www.severalnines.com/downloads/cmon/install-cc.sh $ chmod u+x install-cc.sh $ sudo ./install-cc.sh
This will automate the installation of ClusterControl, but you can read more about this in the ClusterControl Quick Start Guide.
Once the installation is complete, login to the ClusterControl UI at http://192.168.197.100/clustercontrol using your email address (that you entered during the installation process) and default password ‘admin’. You should see something like below:
Preparing the Database Hosts
You do not need to install any agent on the database hosts, but ClusterControl needs to be able to SSH into them and connect to the database instance to gather statistics.
