************************** Laboratorio 2 *****************************
Configuración MySQL Fabric 1.5
*************************************************************************
1. Configuración Privilegios MySQL Fabric
mysql>GRANT ALL ON fabric.* TO 'fabric'@'localhost' identified by 'oracle';
mysql>GRANT ALL ON *.* TO 'fabric'@'localhost' identified by 'oracle' with grant
option;
mysql>flush privileges;

3. 2. Configurar Backing Store Tables
su – mysql
mysqlfabric manage setup
[INFO] 1414161265.564337 - MainThread - Initializing persister: user (fabric), server
(localhost:3306), database (fabric).
[INFO] 1414161266.288218 - MainThread - Initial password for admin/mysql set
Password set for admin/mysql from configuration file.
[INFO] 1414161266.291762 - MainThread - Password set for admin/mysql from configuration
file.
[INFO] 1414161266.292421 - MainThread - Initial password for admin/xmlrpc set
Password set for admin/xmlrpc from configuration file.
[INFO] 1414161266.295928 - MainThread - Password set for admin/xmlrpc from configuration
file.
Nota.- el comando anterior, crea el schema fabric en el nodo State Store
( Fabric Controller )
Verificar que el schema fabric aparece con el siguiente comando:
mysql -uroot -p -e "show schemas;"
Enter password:
+--------------------+
| Database |
+--------------------+
| information_schema |
| fabric |
| mysql |
| performance_schema |
| test |
+--------------------+

4. 3. Iniciar servicio de Fabric Controller:
nohup mysqlfabric manage start &
cat nohup.out

mysqlfabric manage ping
Fabric UUID: 5ca1ab1e-a007-feed-f00d-cab3fe13249e
Time-To-Live: 1
Success (empty result set)
Nota.- debe retornar success
4.- Crear grupo MySQL Fabric
mysqlfabric group create groupTest
Fabric UUID: 5ca1ab1e-a007-feed-f00d-cab3fe13249e
Time-To-Live: 1
uuid finished success result
------------------------------------ -------- ------- ------

En este punto, no hay servers asociados al grupo

6. 4.- Agregar nodos a Grupo
Antes de agregar nodos, el nodo debe cumplir con:
– Tener instalado MySQL 5.6.10 ó superior
Usuario fabric
mysql>GRANT ALL ON fabric.* TO 'fabric'@'localhost' identified by 'oracle';
mysql -uroot -p -S /tmy.
mysql>GRANT ALL ON *.* TO 'fabric'@'localhost' identified by 'oracle' with grant
option;
mysql>flush privileges;
b) Contener un Server UUID único
$DATDIR/auto.cnf
Importante.- el Serer UUID, debe ser un valor único para cada server
mysqlfabric group add groupTest localhost:1300
mysqlfabric group add groupTest localhost:1301
mysqlfabric group lookup_servers groupTest
mysqlfabric group health groupTest
mysqlfabric group promote groupTest
mysqlfabric group lookup_servers groupTest
mysqlfabric group activate ha_group_nombre
