La instalación de Percona XtraDB Cluster es muy sencilla y en entornos Red Hat y derivados se puede hacer a través del repositorio de Percona:
# rpm -Uhv http://www.percona.com/downloads/percona-release/percona-release-0.0-1.x86_64.rpm
Una vez instalado el repositorio simplemente instalamos los paquetes correspondientes:
# yum install Percona-XtraDB-Cluster-server Percona-XtraDB-Cluster-client
En mi caso tras ejecutar la instalación de paquetes vía YUM me encontré con un problema al hacer el Transaction Check:

Existe un conflicto entre la librería MySQL Client instalada en el sistema y la instalación de los paquetes de Percona. La solución es fácil, antes de realizar la instalación de los paquetes de Percona mencionados anteriormente instalamos otro paquete (Percona-Server-shared-compat) que como podéis ver hace que el anterior quede obsoleto y deje de dar problemas:
# yum install Percona-Server-shared-compat Loaded plugins: security Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package Percona-Server-shared-compat.x86_64 0:5.5.32-rel31.0.549.rhel6 will be obsoleting ---> Package mysql-libs.x86_64 0:5.1.66-2.el6_3 will be obsoleted --> Finished Dependency Resolution
Y ahora ya instalamos los paquetes de Percona XtraDB Cluster:
# yum install Percona-XtraDB-Cluster-server Percona-XtraDB-Cluster-client
