2. Getting Started

Step #1

Install the latest ClusterControl:

$ wget http://www.severalnines.com/downloads/cmon/install-cc
$ chmod +x install-cc
$ ./install-cc   # as root or sudo user

If you have multiple network interface cards, assign one IP address for HOST variable as per example below:

$ HOST=192.168.1.10 ./install-cc # as root or sudo user

Note

ClusterControl relies on a MySQL server as a data repository for the clusters it manages and an Apache server for the User Interface. The installation script will always install an Apache server on the host. An existing MySQL server can be used or a new MySQL server install is configured for minimum system requirements. If you have a larger server please make the necessary changes to the my.cnf file and restart the MySQL server after the installation.

If you want to perform a non-interactive installation, you can assign each variable with its value beforehand, similar to example below:

$ S9S_CMON_PASSWORD=cmon S9S_ROOT_PASSWORD=root123 S9S_DB_PORT=3306 HOST=10.10.10.10 ./install-cc

Step #2

Open your web browser to http://[ClusterControl_host]/clustercontrol and create the default Admin user by entering a valid email address and password.

Step #3

Setup passwordless SSH to all target nodes (ClusterControl and all database nodes). Run following commands on ClusterControl server:

$ ssh-keygen -t rsa # press enter on all prompts
$ ssh-copy-id -i ~/.ssh/id_rsa [ClusterControl IP address]
$ ssh-copy-id -i ~/.ssh/id_rsa [Database nodes IP address] # repeat this to all target database nodes

Note

For cloud infrastructure, you may skip this step since all nodes should have been configured with a keypair. Ensure the keypair exists in ClusterControl node and you are good for the next step.

Attention

If you use a non-root user, then it must be in sudoers on all nodes. Read here for details.

Step #4

Deploy a new server/cluster or add an existing database server/cluster into ClusterControl via:

Add Existing Servers/Clusters | Create Database Cluster | Create Database Node

Step #5

Start managing and monitor your database instances:
