 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)

 .. code-block:: yaml

     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

         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)

 .. code-block:: yaml

     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:
                   engine: backupninja
                   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.


 Database management on remote MySQL server

 .. code-block:: yaml

     mysql:
       client:
         enabled: true
         server:
           server01:
             admin:
               host: database.host
               port: 3306
               user: root
               password: password
               encoding: utf8
             database:
               database01:
                 encoding: utf8
                 users:
                 - name: username
                   password: 'password'
                   host: 'localhost'
                   rights: 'all privileges'


 User management on remote MySQL server

 .. code-block:: yaml

     mysql:
       client:
         enabled: true
         server:
           server01:
             admin:
               host: database.host
               port: 3306
               user: root
               password: password
               encoding: utf8
             users:
             - name: user01
               host: "*"
               password: 'sdgdsgdsgd'
             - name: user02
               host: "localhost"


 Sample Usage
 ============

 MySQL Galera check sripts

 .. code-block:: bash

     mysql> SHOW STATUS LIKE 'wsrep%';

     mysql> SHOW STATUS LIKE 'wsrep_cluster_size' ;"

 Galera monitoring command, performed from extra server

 .. code-block:: bash

     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.

 .. code-block:: bash

     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...

 5. service mysql stop
 6. uncomment all wsrep* lines except first server, where leave only in my.cnf wsrep_cluster_address='gcomm://';
 7. start first node
 8. Start third node which is connected to first one
 9. Start second node which is connected to third one
 10. After starting cluster, it must be change cluster address at first starting node without restart database and change config my.cnf.

 .. code-block:: bash

     mysql> SET GLOBAL wsrep_cluster_address='gcomm://10.0.0.2';

	Sample Usage
	============

	MySQL Galera check sripts

	.. code-block:: bash

	mysql> SHOW STATUS LIKE 'wsrep%';

	mysql> SHOW STATUS LIKE 'wsrep_cluster_size' ;"

	Galera monitoring command, performed from extra server

	.. code-block:: bash

	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.

	.. code-block:: bash

	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...

	5. service mysql stop
	6. uncomment all wsrep* lines except first server, where leave only in my.cnf wsrep_cluster_address='gcomm://';
	7. start first node
	8. Start third node which is connected to first one
	9. Start second node which is connected to third one
	10. After starting cluster, it must be change cluster address at first starting node without restart database and change config my.cnf.

	.. code-block:: bash

	mysql> SET GLOBAL wsrep_cluster_address='gcomm://10.0.0.2';
