MySQL Formula

MySQL is the world's second most widely used open-source relational database management system (RDBMS).

Sample Metadata

Standalone setups

Standalone MySQL server

mysql:
  server:
    enabled: true
    version: '5.5'
    admin:
      user: root
      password: pass
    bind:
      address: '127.0.0.1'
      port: 3306
    database:
      name:
        encoding: 'utf8'
        users:
        - name: 'username'
          password: 'password'
          host: 'localhost'
          rights: 'all privileges'
          target: '*.*'

MySQL replication master with SSL

MySQL Galera cluster

MySQL Galera cluster is configured for ring connection between 3 nodes. Each node should have just one member.

Galera initial server (master)

mysql:
  cluster:
    enabled: true
    name: openstack
    role:master
    bind:
      address: 192.168.0.1
    members:
    - host: 192.168.0.1
      port: 4567
    user:
      name: wsrep_sst
      password: password
 server:
    enabled: true
    version: 5.5
    admin:
      user: root
      password: pass
    bind:
      address: 192.168.0.1
    database:
      name:
        encoding: 'utf8'
        users:
        - name: 'username'
          password: 'password'
          host: 'localhost'
          rights: 'all privileges'

MySQL client

Database with initial data (Restore DB)

mysql:
  client:
    server:
      database:
        admin:
          host: localhost
          port: 3306
          user: ${_param:mysql_admin_user}
          password: ${_param:mysql_admin_password}
          encoding: utf8
        database:
          neutron_upgrade:
            encoding: utf8
            users:
            - name: neutron
              password: ${_param:mysql_neutron_password}
              host: '%'
              rights: all
            - name: neutron
              password: ${_param:mysql_neutron_password}
              host: ${_param:single_address}
              rights: all
            initial_data:

              source: ${_param:backupninja_backup_host}
              host: ${linux:network:fqdn}
              database: neutron

Note

This client role needs to be put directly on dbs node. The provided setup restores db named neutron_upgrade with data from db called neutron.

      server01:
        admin:
          host: database.host
          port: 3306

          password: 'sdgdsgdsgd'
        - name: user02
          host: "localhost"

Sample Usage

MySQL Galera check sripts

mysql> SHOW STATUS LIKE 'wsrep%';

mysql> SHOW STATUS LIKE 'wsrep_cluster_size' ;"

Galera monitoring command, performed from extra server

garbd -a gcomm://ipaddrofone:4567 -g my_wsrep_cluster -l /tmp/1.out -d
  1. salt-call state.sls mysql
  2. Comment everything starting wsrep* (wsrep_provider, wsrep_cluster, wsrep_sst)
  3. service mysql start
  4. run on each node mysql_secure_install and filling root password.
Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] n
 ... skipping.

By default, MySQL comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...
  1. service mysql stop
  2. uncomment all wsrep* lines except first server, where leave only in my.cnf wsrep_cluster_address='gcomm://';
  3. start first node
  4. Start third node which is connected to first one
  5. Start second node which is connected to third one
  6. After starting cluster, it must be change cluster address at first starting node without restart database and change config my.cnf.
mysql> SET GLOBAL wsrep_cluster_address='gcomm://10.0.0.2';
