Or if you are running as sudo user: $ ssh -t address] "sudo ls /root"Ĭongratulations, you can now start managing all your instances from ClusterControl. Check that you can run the following command from the ClusterControl host:.Configure passwordless SSH from ClusterControl node to the database nodes:.$ ssh-keygen -t rsa # Press Enter on all prompts Generate an RSA key on ClusterControl node:.** 0.0.0.0 means MySQL is listening on all interfaces of that host. You can use the following command to check: ClusterControl must able to access the MySQL server remotely. Make sure the MySQL servers that you are going to monitor are not listening to local IP address.We assume your MySQL instances have been configured with a root password. 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. Our setup consists of MySQL servers running different versions (5.1, 5.5 and 5.6) and on different hosts: In today’s blog post, we’ll show you how you set that up. 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. So today, it is possible to manage an entire MySQL/MariaDB environment from one interface. The majority, if not all of the cluster users out there, use single-instance or master-slave replicated setups along their mission-critical clusters. With that background, we were pretty excited to introduce support for management of single-instance MySQL and MariaDB databases in ClusterControl 1.2.6. ![]() Cloud, as well as automation and management tools can help improve the number of databases managed by one DBA. Larger databases usually require extra effort around tuning, backup, recovery and upgrade. 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.
