Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Clustercontrol Cookbook

Installs ClusterControl for your new database node/cluster deployment or on top of your existing database node/cluster. ClusterControl is a management and automation software for database clusters. It helps deploy, monitor, manage and scale your database node/cluster.

Supported database clusters:

  • Galera Cluster for MySQL
  • Percona XtraDB Cluster
  • MariaDB Galera Cluster
  • MySQL/MariaDB Replication
  • MySQL/MariaDB single instance
  • MySQL Cluster (NDB)
  • MongoDB Replica Set
  • MongoDB Sharded Cluster
  • PostgreSQL Streaming Replication

Details at Severalnines website.

This cookbook is a replacement for the deprecated cmon cookbook that we have built earlier. It manages and configures ClusterControl and all of its components:

  • Install ClusterControl controller, cmonapi and UI via Severalnines package repository.
  • Install and configure MySQL, create CMON DB, grant cmon user and configure DB for ClusterControl UI.
  • Install and configure Apache, check permission and install SSL.
  • Copy the generated SSH key to all nodes (optional).

If you have any questions, you are welcome to get in touch via our contact us page or email us at info@severalnines.com.

  • CentOS, Redhat, Fedora
  • Debian, Ubuntu

  • SELinux/AppArmor must be turned off. Services or ports to be enabled are listed here.

Attributes

Please refer to attributes/default.rb

Data Bags

Data items are used by the recipe to configure SSH public key on database hosts, grants cmon database user and setting up CMON configuration file. We provide a helper script located under clustercontrol/files/default/s9s_helper.sh. Please run this script prior to the deployment.

Helper script - s9s_helper.sh

$ cd ~/chef-repo/cookbooks/clustercontrol/files/default
$ ./s9s_helper.sh
==============================================
Helper script for ClusterControl Chef cookbook
==============================================

ClusterControl will install a MySQL server and setup the MySQL root user.
Enter the password for MySQL root user [default: 's3cr3tcc'] : R00tP4ssw0rd

ClusterControl will create a MySQL user called 'cmon' for automation tasks.
Enter the password for user cmon [default: 's3cr3tcc'] : Bj990sPkj

ClusterControl will need a sudo user (from ClusterControl to all managed nodes) to perform automation tasks via SSH.
Enter the SSH user [default: root] : dbadmin

Generating config.json..
{
    "id" : "config",
    "mysql_root_password" : "R00tP4ssw0rd",
    "cmon_password" : "Bj990sPkj",
    "cmon_ssh_user" : "dbadmin",
    "cmon_user_home" : "/home/dbadmin",
    "clustercontrol_api_token" : "fe74e6d6918b71a48eb039e495b68b41d19e49ad"
}

Data bag file generated at /home/vagrant/.chef/cookbooks/clustercontrol/files/default/config.json
To upload the data bag, you can use following command:
$ knife data bag create clustercontrol
$ knife data bag from file clustercontrol /home/vagrant/.chef/cookbooks/clustercontrol/files/default/config.json

Reupload the cookbook since it contains a newly generated SSH key:
$ knife cookbook upload clustercontrol

Answer all questions and at the end of the wizard, it will generate a data bag file called config.json and a set of command that you can use to create and upload the data bag. If you run the script for the first time, it will ask to re-upload the cookbook since it contains a newly generated SSH key:

$ knife data bag create clustercontrol
Created data_bag[clustercontrol]

$ knife data bag from file clustercontrol /home/ubuntu/chef-repo/cookbooks/clustercontrol/files/default/config.json
Updated data_bag_item[clustercontrol::config]

$ knife cookbook upload clustercontrol
Uploading clustercontrol [0.1.8]
Uploaded 1 cookbook.

We highly recommend you to use encrypted data bag since it contains confidential information

Then, create a role, cc_controller:

$ cat cc_controller.rb
name "cc_controller"
description "ClusterControl Controller"
run_list ["recipe[clustercontrol]"]

Add the defined roles into Chef Server:

$ knife role from file cc_controller.rb
Updated Role cc_controller!

Assign the roles to the relevant nodes:

$ knife node run_list add clustercontrol.domain.com "role[cc_controller]"

Finally, on the client side (ClusterControl host), apply the cookbook:

$ sudo chef-client

ClusterControl general options

Following options are used for the general ClusterControl set up:

id

  • The data item identifier. Do not change this value.

cmon_password

  • Specify the MySQL password for user cmon. The recipe will grant this user with specified password, and is required by ClusterControl.
  • Default: 's3cr3tcc'

mysql_root_password

  • Specify the MySQL root password. This recipe will install a fresh MySQL server and it will create a MySQL user.
  • Default: 's3cr3tcc'

clustercontrol_api_token

  • 40-character ClusterControl token generated from s9s_helper script.
  • Example: 'b7e515255db703c659677a66c4a17952515dbaf5'

cmon_ssh_user

  • SSH user that will be used by ClusterControl to connect to all managed nodes. This user must be able to escalate as super-user.
  • Default: 'root'

Usage

clustercontrol::default, clustercontrol::controller

For ClusterControl host, just include clustercontrol or clustercontrol::controller in your node's run_list:

{
  "name":"clustercontrol_node",
  "run_list": [
    "recipe[clustercontrol]"
  ]
}

clustercontrol::db_hosts

For database hosts, include clustercontrol::db_hosts in your node's run_list:

{
  "name":"database_nodes",
  "run_list": [
    "recipe[clustercontrol::db_hosts]"
  ]
}

** Do not forget to generate databag before the deployment begins! Once the cookbook is applied to all nodes, open ClusterControl web UI at https://[ClusterControl IP address]/clustercontrol and create the default admin user with a valid email address.
