Como desligar um servidor Debian e um UPS com bateria fraca?

Como configurar um servidor Debian com um UPS USB independente para:

  1. Inicie o desligamento do UPS após um minuto quando a bateria estiver fraca.
  2. Desligar em si.
  3. E para ter certeza de que quando a energia elétrica for restaurada (mesmo antes de o UPS acabar) o servidor Debian será iniciado.

Essas etapas são descritas emessa questãomas não há explicação de como alcançá-los.

Eu tenho:

  • Meu servidor configurado para sempre iniciar quando a energia for restaurada.
  • Instalado nute quando executo upsc myupsvejo as informações do no-break, incluindo o nível da bateria. Assim, posso escrever facilmente um script para monitorar a bateria e desligar o servidor.

Minha pergunta é:

Como enviar um comando de desligamento para o UPS?

O UPS é:EATON 5E 650i

Em /etc/nut/nut.confeu tenho:

MODE=standalone

Em /etc/nut/ups.confeu tenho:

[myups]
    driver = usbhid-ups
    port = auto
    vendorid = 0463
    pollfreq = 30

upsc myupsimpressões:

OK, acho que está funcionando agora. Aqui está o que eu fiz:

apt-get install nut-server

apt-get install nut-client

nano /etc/nut/nut.conf

MODE=standalone

nano /etc/nut/ups.conf

[myups]
    driver = usbhid-ups
    port = auto
    vendorid = 0463
    pollfreq = 30

/sbin/upsdrvctl start

upsc myups Imprime alguns problemas.

Reinício /usr/sbin/shutdown -r now

Agora, ao executar, upsc myupsvocê deverá ver as informações do seu UPS:

Se /sbin/upsmonimprimir algo como:

Network UPS Tools upsmon 2.7.4
fopen /var/run/nut/upsmon.pid: No such file or directory
Using power down flag file /etc/killpower

Fatal error: insufficient power configured!

Sum of power values........: 0
Minimum value (MINSUPPLIES): 1

Edit your upsmon.conf and change the values.

tentar:nano /etc/nut/upsd.users

[upsmon]
    password  = mypassword
    upsmon master

chmod 640 /etc/nut/upsd.users

ls -lahrt /etc/nut/upsd.users

-rw-r----- 1 root nut 2,2K Dec 13 13:15 /etc/nut/upsd.users

nano /etc/nut/upsmon.conf

MONITOR myups@localhost 1 upsmon mypassword master

systemctl enable nut-monitor

/sbin/upsmon

Network UPS Tools upsmon 2.7.4
fopen /var/run/nut/upsmon.pid: No such file or directory
UPS: myups@localhost (master) (power value 1)
Using power down flag file /etc/killpower

Aqui está o que pode ser visto no syslog quando testei cortando a eletricidade:

Após a inicialização, quando executo, upsmonvejo o seguinte:

/sbin/upsmon

Network UPS Tools upsmon 2.7.4
Fatal error: A previous upsmon instance is already running!
Either stop the previous instance first, or use the 'reload' command.

O que significa que está funcionando e está tudo bem, eu acho :)
