Import a Database Cluster

Table of Contents

Choose from the list of database cluster technology, vendors, and versions to import an existing database server or cluster. The following database cluster types are supported:

MySQL/MariaDB (standalone or replication)
- Oracle MySQL
- Percona Server for MySQL
- MariaDB Server
Galera Cluster
- Percona XtraDB Cluster
- MariaDB Cluster
PostgreSQL and EnterpriseDB (standalone or streaming replication)
TimescaleDB (standalone or streaming replication)

ElasticSearch 7.x and 8.x.
Microsoft SQL Server – 2019 and 2022 for Linux
Valkey Cluster

There are some prerequisites that need to be fulfilled prior to adding the existing setup. The existing database cluster/server must:

Verify that sudo is working properly if you are using a non-root user. See Operating System User.
Passwordless SSH from ClusterControl node to database nodes has been configured correctly. See Passwordless SSH.
The target cluster must not be in a degraded state. For example, if you have a three-node Galera cluster, all nodes must be alive, accessible, and in sync.

For more details, refer to the Requirements section. Each time you add an existing cluster or server, ClusterControl will trigger a job under ClusterControl v2 → Activity Center → Jobs. You can see the progress and status on this page. Click on … of the importing job and click Details. A window will also appear with messages showing the progress.

MySQL Replication

ClusterControl is able to manage and monitor an existing set of MySQL/MariaDB servers (standalone or replication). Individual hosts specified in the same list will be added to the same server group. ClusterControl assumes that you are using the same MySQL root password for all instances specified in the group and it will attempt to determine the server’s role as well (primary, replica, multi or standalone).

The following vendors and versions are supported:

Oracle MySQL – 8.0.
Percona Server for MySQL – 8.0.
MariaDB Server – 10.4, 10.5, 10.6, 10.11 and 11.4 LTS.

When importing an existing MySQL Replication, ClusterControl will do the following:

Verify SSH connectivity to all nodes.
Detect the host environment and operating system.
Discover the database role of each node (primary, replica, multi, standalone).
Pull the configuration files.
Generate the authentication key and register the nodes into ClusterControl.

Field	Description
Cluster Details
Cluster name	Specify a name for the cluster. If blank, ClusterControl will generate a name for the cluster.
Tags	Specify tags for the cluster. Press Enter for every new tag defined. Tags are useful to group your database clusters and simplify lookup and filtering.
SSH Configuration
SSH user	Specify “root” if you have root credentials. If you use `sudo` to execute privileged system commands, specify the name that you wish to use here. The user must exist on all nodes. See Operating System User.
SSH user key path	Specify the full path of the SSH key (the key must exist on the ClusterControl node) that will be used by the SSH user to perform passwordless SSH. See Passwordless SSH.
SSH sudo password	If you use `sudo` with a password, specify it here. Ignore this if the SSH user is root or the sudoer does not need a sudo password.
SSH port	Specify the SSH port for the target nodes. ClusterControl assumes SSH is running on the same port on all nodes.
Node Configuration
Server port	MySQL server port. The default is 3306.
Server data directory	Location of MySQL/MariaDB data directory. Default is `/var/lib/mysql`.
Admin/Root user	Specify the MySQL root user. This user will be granted global SUPER permission and the GRANT option.
Admin/Root password	Specify the MySQL root password. ClusterControl will configure the same MySQL root password for all instances in the cluster.
Information_schema queries	On – Enables information schema queries to track databases and table growth. Queries to the information schema may not be suitable when having many database objects (hundreds of databases, hundreds of tables in each database, triggers, users, events, stored procedures, etc). If disabled, the query that would be executed will be logged so it can be determined if the query is suitable for your environment. This is not recommended for clusters with more than 2000 database objects. Off – Disables information schema queries to track databases and table growth.
Cluster auto-recovery	On – ClusterControl will perform automatic recovery if it detects the cluster is down or degraded. See Cluster Recovery. Off – ClusterControl will not perform automatic recovery if it detects the cluster is down or degraded.
Node auto-recovery	On – ClusterControl will perform automatic recovery if it detects any of the nodes in the cluster is down. See Node Recovery. Off – ClusterControl will not perform automatic recovery if it detects any of the nodes in the cluster is down.
Add Nodes
Node	IP address or hostname of the database node. Press Enter to add the node, where ClusterControl will perform a pre-deployment check to verify if the node is reachable via SSH key-based authentication. If the target node has more than one network interface, you will be able to select or enter a separate IP address to be used only for database traffic. With all the database nodes specified, ClusterControl will figure out the topology and server’s role for every database node (even for a standalone setup).

MySQL Galera

ClusterControl is able to manage and monitor an existing set of Galera Cluster. ClusterControl assumes that you are using the same MySQL root password for all instances specified in the group. If you have one or more asynchronous slaves attached to the Galera Cluster, specify it later on once the cluster is imported into ClusterControl by going to Add replication node → Import a replication node. Similarly, when importing the load balancers, go to Add load balancer → Import balancer to import them afterward.

When importing an existing Galera Cluster, ClusterControl will perform the following:

Verify SSH connectivity to all nodes.
Detect the host environment and operating system.
Detect the remaining nodes in the cluster, only if Automatic node discovery is ON.
