Instalando Zimbra 8.0.6 sobre Red Hat 6.5

Ya ha pasado casí un año de la entrada que preparé para la instalación de Zimbra 8.0.3 sobre Ubuntu 12.04, con un total de 11.439 personas a día de hoy que han disfrutado esta entrada y aprendido a desplegar Zimbra sobre Ubuntu 12.04 de manera rápida, en Singleserver.1

Hoy os traigo las instrucciones para desplegarlo sobre Redhat 6.5, y de esta manera poder tener nuestra plataforma Zimbra, sobre un entorno licenciado y con soporte de fabricante, como es Red Hat. Está especialmente orientado a empresas que necesiten tener soporte de fabricante detrás, por ese motivo también habría que contratar e instalar Zimbra Network Edition (en el tutorial vemos como se instala Opensource Edition).

Vamos allá con el menú

1.- Preparación del Servidor
2.- Instalación del Sistema Operativo
3.- Preparación del Sistema Operativo para Zimbra
3.1.- Suscripción con Red Hat
3.2.- Configuración de DNS
4.- Instalación de Zimbra ZCS OSE 8.0.6
4.1.- Firewall de Red Hat
5.- Visualizando el Panel de Control
6.- Visualizando la interfaz AJAX
7.- Agregar funcionalidades de Maletín y S/MIME
8.- Zimbra Acceso Móvil
9.- Jugando a ser Dioses, modo flujo de actividad
10.- Conclusiones

1.- Preparación del Servidor

Lo primero es crear nuestra VM para Red Hat, vamos a ver el paso a paso:

En nuestro VMWare Workstation pulsaremos File> New Virtual Machine. Seleccionaremos el modo de configuración Typical y pulsaremos “Next”.

Buscaremos la ISO del DVD bajada desde Red Hat.

En el Guest Operating System, seleccionaremos Red Hat Enterprise Linux 6 64-bit.

El nombre que gustemos para nuestra VM, en mi caso Zimbra8-RHEL6

Con 20GB para el entorno de Laboratorio es más que suficiente, para vosotros, depende de vuestras necesidades y cuentas y tamaño de cada cuenta. Al ser virtual, se puede expandir en el futuro, además usaremos LVM que puede expandirse de manera muy simple. Yo siempre marco que me guarde el fichero como un único fichero.

Una vez terminamos todo, veremos el resumen, algo corto en memoria y vCPU, vamos a editarlo.

Después de las modificaciones quedará así, sin disquetera, con 4GB de RAM, 2 vCPU, y la red en modo Bridged.

2.- Instalación del Sistema Operativo

Al encender la VM, nos cargará desde el DVD de Red Hat y veremos el siguiente menú, pulsaremos Intro directamente, sin realizar ninguna de las opciones presentes.

Empezará a cargar todo lo necesario para la instalación.

Y veremos una instalación gráfica basada en Anaconda, que siempre es de agradecer para las personas menos duchas en Linux. Pulsaremos Next.

De idioma para la instalación seleccionaremos English y pusalremos Next.

Como teclado marcaremos Spanish y pulsaremos Next.

A la hora de seleccionar sobre que disco instalar Red Hat, tenemos Basic Storage (discos o unidades locales) o sobre Almacenamiento especializado, si tuvieramos un disco presentado por iSCSI, o Boot from SAN, Fibra, etc. Seleccionaremos la primera y pulsaremos Next

Nos mostrará nuestro disco de 20GB que hemos presentado a nuestra VM. Seleccionaremos Yes, discard any data, para borrar todo el disco y usarlo para la instalación.

Para el hostname usaremos el que queramos, recordemos que debe resolver vía DNS con una entrada de tipo A y preferiblemente una entrada MX también. Configuraremos la parte de Red desde aquí también, marcaremos Configure Network.

Seleccionaremos la red cableada (wired) y pulsaremos Edit.

En la pestaña IPv4 debe quedar de la siguiente manera, Manual > con la IP que queramos, de DNS uno público, o uno interno que nos resuelva el hostname anteriormente puesto y un dominio de búsqueda. Pulsaremos Apply.

Para la parte de la zona de tiempo, seleccionaremos en el Mapa, Madrid y pulsaremos Next

Introduciremos una contraseña para nuestro sistema y la confirmaremos y pulsaremos Next

Para la parte de disco, usaremos la opción Use All Space, esto creará un particionamiento recomendado, según RAM y espacio para crear la SWAP, etc, si queremos crear nuestro propio particionamiento, seleccionaremos Create Custom Layout. Pulsaremos Next

Marcamos que si queremos guardar los cambios en el disco.

Es la hora de seleccionar de que manera queremos preconfigurar el servidor, tenemos varias opciones, las cuales cada una trae unos paquetes u otros. Vamos a seleccionar Basic Server, posteriormente tendremos que eliminar postfix ya que lo adjunta esta configuración. Pulsaremos Next

Y el asistente comenzará a instalar los paquetes y dependencias necesarias para el correcto funcionamiento de nuestro Red Hat.

Una vez ha terminado, pulsaremos el botón de Reboot para continuar con nuestro tutorial.

3.- Preparación del Sistema Operativo para Zimbra

El primer paso es esperar que la VM arranque con nuestro Sistema Operativo Red Hat.

3.1.- Suscripción con Red Hat

El siguiente paso es Suscribir nuestra VM con la página de Suscripciones de Red Hat, tenemos una trial de 30 días sin compromiso.

Los comandos a lanzar son los siguientes:
[root@zimbra8-rhel6]# subscription-manager register

Y nos solicitará nuestro Usuario y  Contraseña del portal de Red Hat.
En la captura estoy rehaciendo el proceso de suscripción y he tenido que introducir lo siguiente:
[root@zimbra8-rhel6]# subscription-manager register –force

Como vemos más arriba, el sistema nos devuelve un UUID, que es único.
Ahora nos iremos hasta nuestro portal de suscripción donde podremos ver un resumen de las licencias que tenemos válidas y compradas para usar, tanto para sistemas físicos como para Virtuales o Hypervisores. Os dejo la lista de precios aquí.

Si pulsamos en Administración de suscripciones en la ventana anterior, podremos ver un listado con nuestros Red Hat y nos dirá si están correctamente suscritos o no. En nuestro caso vemos en la imagen un mensaje en rojo donde nos indica que no está suscrito.

Podemos pulsar en Attach a subscription, esquina inferior derecha, y seleccionar la de 30 días para entorno virtual que tenemos disponible. O nuestra licencia que hayamos comprado a Red Hat.

Marcamos la virtual de 30 días de prueba y pulsamos en Attach Selected.

Y ya podremos ver que nuestro sistema y su UUID está suscrito y estamos consumiendo una suscripción.

Ya podremos volver al Sistema Operativo y realizar un yum update para actualizar dependencias.

Desinstalando Postfix: Tendremos que desinstalar Postfix antes de continuar con la instalación:

[root@zimbra8-rhel6]# rpm -qa | grep postfix
 postfix-2.6.6-6.el6_5.x86_64
 [root@zimbra8-rhel6]#
 [root@zimbra8-rhel6]#
 [root@zimbra8-rhel6]# /etc/rc.d/init.d/postfix stop
 Shutting down postfix: [ OK ]
 [root@zimbra8-rhel6]# rpm -e --nodeps postfix-2.6.6-6.el6_5.x86_64
 [root@zimbra8-rhel6]#

E instalar el paquete nc, ya que el resto de dependicas al seleccionar Basic Server, ya vienen incluidas:

yum install nc

3.2.- Configuración de DNS

De manera externa: Lo normal en un entorno donde queremos instalar un Red Hat licenciado y un Zimbra Network Edition, es que usemos un servidor DNS corporativo, ya sea de Microsoft o un BIND/Named, etc. En otro servidor, como en la siguiente imagen:

4.- Instalación de Zimbra ZCS Open Source Edition 8.0.6

Ha llegado la hora de instalar el software de Zimbra, vamos a descargar la última versión de Zimbra, 8.0.6:

[root@zimbra8-rhel6]# wget http://files2.zimbra.com/downloads/8.0.6_GA/zcs-8.0.6_GA_5922.RHEL6_64.20131203103705.tgz

Procedemos a descomprimir zimbra:

root@zimbra8:~# tar -xzvf zcs-8.0.6_GA_5922.RHEL6_64.20131203103705.tgz

Y procederemos a instalar Zimbra:

[root@zimbra8-rhel6 zcs-8.0.6_GA_5922.RHEL6_64.20131203103705]# ./install.sh

You have the option of notifying Zimbra of your installation.
This helps us to track the uptake of the Zimbra Collaboration Server.
The only information that will be transmitted is:
The VERSION of zcs installed (8.0.6_GA_5922_RHEL6_64)
The ADMIN EMAIL ADDRESS created ([email protected])

Notify Zimbra of your installation? [Yes]

Configuration complete - press return to exit

Siempre está bien notificar a Zimbra que hemos instalado su producto, de esta manera se pueden hacer mejores estudios de mercado y seguir progresando.

4.1.- Firewall de Red Hat

Una opción que tenemos, es deshabilitarlo, pero desde aquí no lo recomiendo, simplemente siguiendo estos pasos en nuestro Red Hat, tendremos un servidor Zimbra securizado a nivel de red:

La configuración en bruto de iptables se guarda en /etc/sysconfig/iptables, con lo que haremos un vi a este fichero e introduciremos lo siguiente:

# Configuración de Firewall esrita por jorgedelacruz.es
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 25 -j ACCEPT 
-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT 
-A INPUT -p tcp -m state --state NEW -m tcp --dport 110 -j ACCEPT

-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

 

Nos aseguraremos que nuestro script de iptables arranca con el Sistema Operativo

# chkconfig --level 345 iptables on

 

Y reiniciamos los servicios para que aplique los cambios

/etc/init.d/iptables restart

Vía Carles Pla: Recomiendo encarecidamente desactivar SElinux, aveces suele dar algún problema:
Primero comprobamos si esta Activo:

[root@carles ~]# getenforce
 Disabled

Si no lo desactivamos:

[root@carles ~]# setenforce 0

Finalmente editamos la configuración:

vim /etc/selinux/config

y modificamos el campo

SELINUX=enforcing a SELINUX=disabled

reiniciamos el SO, y voilà, ya está. Comentar que esto también sirve en CentOS

5.- Visualizando el nuevo Panel de Control

Lo primero que pensamos al entrar en el nuevo panel de control es que VMware ha intentado unificar todos sus productos y sus formularios login, sin duda nos recuerda a la interfaz Horizon.

Para acceder tendremos que irnos a la siguiente URL > https://midominio.com:7071

6.- Visualizando la nueva interfaz Ajax

Pero sin duda algo ha sufrido cambios de esta versión es sin duda la interfaz de cliente, a la que se ha añadido unas mejoras, que aunque puedan parecer sutiles, son realmente una novedad muy grande y ahorros de tiempo enormes y de productividad.

Para entrar en la interfaz de usuario iremos a la siguiente dirección > https://midominio.com o https://IPDELSERVERZIMBRA

Probamos a crear un nuevo correo y adjuntar una imagen en formato attachment y embebebida, lo logramos en muy pocos pasos y muy rapido. Cabe destacar que el editor wysiwyg ha sido rediseñado pudiendo ahora embeber una imagen de manera muy sencilla, en la foto os dejo una foto con mi buen amigo BiGaS de La Quimera en Corto, y yo, detrás de la Casa Blanca. El correo me lo he mandado a mi mismo para ver como vemos este documento en nuestra bandeja de entrada.

El correo lo veremos de la siguiente manera, en formato completamente HTML en nuestro Inbox.

Otra bondad que me parece muy interesante, colorida y funcional, es ordenar los correos por Tags, etiquetas, nada nuevo, solo que en zimbra 8 nos permite que todo el contenido del Email cambié en la Bandeja de Entrada, pudiendo localizar los correos de una manera muy granular y elegante, observemos, solo con etiquetar los emails, ya se auto coloreará todo lo demas.

Para activar esta interesante funcionalidad tendremos que ir a Preferencias > Correo > Visualización de Mensajes y activar lo siguiente:

7.- Agregar funcionalidades de Maletin y S/MIME

Una de las cosas que nos llama la atención es no tener Maletín directamente, en este punto vamos a ver como habilitar el Maletín y las funciones de S/MIME en nuestro dominio.

Nos iremos hasta Configurar > Clase de Servicio > Y editamos la clase de Servicio que tengamos, en nuestro caso “default”

Marcaremos las casillas de Maletín y abajo del todo Activar S/MIME para activarlo en nuestro dominio.

Una vez hecho esto, podremos irnos de nuevo a nuestra interfaz y veremos estos dos cambios implementados, el primero nuestro Maletín, donde podremos visualizar la mayoría de documentos, imágenes, PDF, etc. Es cierto que para esta versión 8, ficheros de Suite Ofimática Microsoft, nos salta directamente un popup para abrirlos con nuestro software local. Y el segundo, el S/MIME, si tenemos licencia lo veremos activado al enviar un nuevo email, en modo Demo no podremos ejecutarlo.

8.- Zimbra Acceso Móvil

En el acceso móvil sólo han cambiado la pantalla de login, una pena la verdad ya que parecía que iban a integrar un cambio radical en este aspecto. Supongo que aprovecharán su aplicación exclusiva para móviles. Aquí algunas pantallas de la interfaz web móvil.

Por 7,36€ y en USA solamente por el momento, podremos adquirir la aplicación VMware Horizon Mail, una aplicación muy potente para Android, podéis comprarla aquí.

9.- Jugando a ser Dioses, modo flujo de actividad

Una de las mejores nuevas funciones es el Flujo de Actividad, nos permitirá mediante una serie de reglas avanzadas, realizar una serie de acciones avanzadas también. Veamos como activarlo. Nos iremos a Preferencias > Filtros > Filtros de flujo de actividad para activarlo. En la primera configuración ya podemos activar los dos checkbox que vemos en la imagen y quitarnos buena parte del correo de baja prioridad que recibimos diariamente.

Dentro de un Flujo podremos seleccionar entre todas estas posibilidades para categorizar nuestros emails, y tratar los que seleccionemos como baja prioridad, o alta, en caso que seleccionemos unos mails de determinadas personas o palabras concretas y le añadamos después una etiqueta, que anteriormente hemos puesto en rojo por ejemplo. Hay mil y un ejemplos para hacer del Flujo de Actividad, una extensión de como pensamos y como nos organizamos con nuestra herramienta más importante, el correo electrónico.

 

10.- Conclusiones

Las conclusiones de Zimbra 8.0.6 sobre Red Hat son las siguientes:

• El soporte a nivel de Sistema Operativo de Red Hat, otorga a empresas de cierto volumen el requisito perfecto para implementar Zimbra Network Edition y Red Hat. De esta manera tenemos un producto de core de la empresa, como es el correo, licenciado y con soporte de ambos fabricantes.
• El rendimiento es similar a Ubuntu 12.04
• El modo Flujo de Actividad nos permitirá tener controlado todo nuestro buzón y hacer con los correos lo que queramos, literalmente. Digamos que tenemos un asistente las 24 horas del día echandonos una mano para saber si un correo es de alta prioridad o de baja.
• Traer soporte nativo para S/MIME es realmente muy bueno y nos permitirá securizar nuestro envio de emails de una manera mas sencilla.
• Punto negativo la interfaz web y el precio de la palicación para Android, y la restricción de USA.
