+======
+Galera
+======
+
+Galera Cluster for MySQL is a true Multimaster Cluster based on synchronous replication. Galera Cluster is an easy-to-use, high-availability solution, which provides high system uptime, no data loss and scalability for future growth.
+
+Sample pillars
+==============
+
+Galera cluster master node
+
+.. code-block:: yaml
+
+    galera:
+      master:
+        enabled: true
+        name: openstack
+        bind:
+          address: 192.168.0.1
+          port: 3306
+        members:
+        - host: 192.168.0.1
+          port: 4567
+        - host: 192.168.0.2
+          port: 4567
+        admin:
+          user: root
+          password: pass
+        database:
+          name:
+            encoding: 'utf8'
+            users:
+            - name: 'username'
+              password: 'password'
+              host: 'localhost'
+              rights: 'all privileges'
+
+Galera cluster slave node
+
+.. code-block:: yaml
+
+    galera:
+      slave:
+        enabled: true
+        name: openstack
+        bind:
+          address: 192.168.0.2
+          port: 3306
+        members:
+        - host: 192.168.0.1
+          port: 4567
+        - host: 192.168.0.2
+          port: 4567
+        admin:
+          user: root
+          password: pass
+
+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';
