Clonar Máquina Virtual en VMware ESXi 5

Nos logueamos al vSphere Client y vamos a "Configuración"

Vamos a la solapa izquierda y seleccionamos "Storage", hacemos click derecho sobre datastore y "Browse Datastore..."

Creamos una nueva carpeta haciendo click en el cuadro rojo:

Elegimos el nombre que deseamos:

Copiamos desde la carpeta origen todos los archivos que terminen en .vmx y en .vmdk:

Seleccionamos la carpeta destino y luego "Pegar":

Esperamos que terminen de copiar los files:

Una vez copiada, boton derecho sobre el .vmx y "Add to Inventory":

Ingresamos el nombre de la Virtual y "Next":

Elegimos el ESXi server de la lista, "Next" nuevamente:

"Finish":

Tildamos sobre "I copied it" y "Ok":

Proxy Reverso para Glassfish con Apache

Ya he explicado como hacer un reverse proxy en el anterior post:

http://www.redes-seguridad.com.ar/2013/08/reverse-proxy-con-apache-2-en-debian.html

Pero con Glassfish no me funcionaba así que habilité el módulo  "rewrite":

# a2enmod rewrite
Enabling module rewrite.
Run '/etc/init.d/apache2 restart' to activate new configuration!

Reiniciamos apache:

# /etc/init.d/apache2 restart
Restarting web server: apache2 ... waiting .

Editamos la config del apache:

# vim /etc/apache2/httpd.conf

 ProxyPreserveHost on
 RewriteEngine on
 ProxyPass /glassfish http://mi_glassfish.com.ar:8080/
 ProxyPassReverse /crp http://mi_glassfish.com.ar:8080/
 Redirect / http://mi_glassfish.com.ar:8080/
 RewriteRule ^/(.*) mi_glassfish.com.ar:8080/$1 [P,L]

Reiniciamos apache:

# /etc/init.d/apache2 restart
Restarting web server: apache2 ... waiting .

# usermod -a -G glassfishadm root

Instalamos los requerimientos:

# apt-get install python-software-properties

Agregamos los repositorios:

# vim /etc/apt/sources.list

Registrar Licencia ESXi 5.1

Ya había explicado hace un tiempo como registrar la licencia de VMware ESXi 5.0 en este enlace: http://www.redes-seguridad.com.ar/2011/10/registrar-licencia-esxi-50.html

Ahora voy a mostrar como actualizarla en ESXi 5.1

Nos logueamos al vSphere Client, vamos a la solapa "Configuration" y luego "Edit":

Seleccionamos "Assing a new license key to this host" -> "Enter key":

Ingresamos la licencia y listo "OK":

Instalando VMware ESXi 5.1 on HP Proliant ML310e Gen8

Después de configurar el RAID 1 en dicho server, con el provissioning de HP e instalar VMware ESXi 5.1 reiniciaba el equipo y quedaba en un loop y decía que no encontraba nada en el disco C:

Luego de investigar un poco llegué a que la placa del smart es una "Smart Array B120i" y parece que no era compatible con la ESXi 5.1


SOLUCION:

Bajar una imagen customizada de VMware para Servidore Proliant: http://h18004.www1.hp.com/products/servers/software/vmware/esxi-image.html


Bajando la siguiente imagen me funcionó correctamente: https://my.vmware.com/group/vmware/details?downloadGroup=HP-ESXI-5.1.0U1-GA-25APR2013&productId=327&download=true&fileId=59b519a2470863f7ae07e7c3ffef3e17&secureParam=8cbd080ed2cafbbbf04160a7fb2720d4&downloadType=

TCP-MIB::tcpInErrs.0 = Counter32: 0
TCP-MIB::tcpOutRsts.0 = Counter32: 18
......

Si sólo queremos que SNMP sea consultado desde localhost y de una única ip:

Editamos el archivo de iptables nuevamente y agregamos el source la ip de nagios 192.168.0.10 (sólo podremos hacer consultas SNMP de dicha ip)

# vi /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT -p udp --dport 161 -s 192.168.0.10 -j ACCEPT

Reiniciamos iptables:

# service iptables restart

Probamos el script de chech_openmanage para configurar en nagios:

La ip 192.168.0.100 es la ip donde instalamos el OMSA:

# /usr/local/apps/nagios/libexec/check_openmanage -H 192.168.0.100 -C mi_comunidad
OK - System: 'PowerEdge R200', SN: '72U54M5', 8 GB ram (4 dimms), 1 logical drives, 2 physical drives
