VMWare: ESXi reiniciar servicios con services.sh

En un host VMWare ESXi encontraremos el siguiente shell script: services.sh en el directorio /bin.

Los ficheros dentro del directorio /bin están situados en el path del sistema, así que podrán ser llamados desde cualquier ruta.

Este shell script (services.sh) permite reiniciar todos los servicios del host ESXi sin reiniciar el host.

El script acepta como parámetros: start, stop y restart.

Es importante tener en cuenta que si ejecutamos services.sh stop, perderemos toda conectividad con el host y no quedará recuperada de forma automática, ya que todos los servicios quedarán detenidos.

Podemos ejecutar este script desde la shell del sistema.

Funcionamiento interno del script:

El script lista los servicios configurados como activos con el comando: chkconfig -io.

Con el comando service start y service stop, se reinician los servicios.

Con el comando localcli network firewall ruleset, se actualizan las reglas en el firewall.

Contenido del script:

~ # cat /bin/services.sh
#!/bin/sh

export PATH=/sbin:/bin

log() {
   echo "$*"
   logger init "$*"
   esxcfg-init --set-boot-status-text "$*"
   esxcfg-init --set-boot-progress step
}

# Try esxcli to set firewall first. If return value is not 0,
# that demonstrates hostd is not up, yet. Then try localcli,
# which always succeeds. Setting firewall in this way,
# guarantees new settings sync to hostd cache.
update_ruleset_status() {
   /sbin/esxcli network firewall ruleset set -r $1 -e $2
   if [ $? -ne 0 ]; then
      /sbin/localcli network firewall ruleset set -r $1 -e $2
