| Website Setup, UPS Monitor... |
| Follow the instructions below to install the software to monitor the
Uninterrupted Power Supply (UPS). There are 2 different packages with Debian (Etch)
that I've used. The 'NUT' package is more versatile and can be used for most power
supplies - but is more difficult to understand and configure. The 'APCUPSD' package
is for APC power supplies only, but is more easy to understood and configure. The
information below is one example for each package - your configuration may be different.
The 'NUT' example is followed by the 'APCUPSD' example. |
- Login the server as root.
- Type: apt-get install nut
- When requested, enter 'y' to continue the installation.
- If needed, install the requested Debian CD and press enter.
- If the UPS is connected to a USB port, Type: apt-get install nut-usb
When requested, enter 'y' to continue the installation.
- Type: cp /usr/share/doc/nut/examples/* /etc/nut
- Type: cd /etc/nut
- Type: gunzip ./upsmon.conf.gz
- Type: chown nut ./*
- Type: chgrp nut ./*
- Both Web & DNS servers share the same UPS supply. Review the changes to the
configuration files listed below.
- To query the status of the ups supply from the primary, type: upsc web_servers@localhost
To query the status of the ups supply from the secondary, type: upsc web_servers@fc2.caauwe.com

| Filename: /etc/nut/ups.conf |
| This file contains the description of the UPS supply connected directly
to the USB port. The example below is for the fc2 server. |
[web_servers]
driver = newhidups
port = /dev/usb/hiddev0
desc = "Web Servers" |
|
| Filename: /etc/nut/upsd.conf |
| This file contains the IP addresses that may communicate with the upsd
server. The example below is for the fc2 server. |
ACL all 0.0.0.0/0
ACL localhost 127.0.0.1/32
ACL localnet 192.168.0.0/16
ACCEPT localhost
ACCEPT localnet
REJECT all |
|
| Filename: /etc/nut/upsd.users |
| This file contains the user-id and passwords to perform commands.
The example below is for the fc2 server (replacing '<password>' with the password of
your choice. |
[upsadmin]
password = <password>
allowfrom = localhost
actions = set
instcmds = all
[upsmaster]
password = <password>
allowfrom = localhost
upsmon master
[upsslave]
password = <password>
allowfrom = localnet
upsmon slave |
|
| Filename: /etc/nut/upsmon.conf |
This file contains many parameters, but the only command that needs to be
added is the 'MONITOR' command. The passwords are the same as the ones listed in the
/etc/nut/upsd.users file.
For server fc1. |
| MONITOR web_servers@fc2.caauwe.com 1 upsslave
<password> slave |
| For server fc2. |
| MONITOR web_servers@localhost 1 upsmaster
<password> master |
|
| Filename: /etc/default/nut |
This file indicates what components of nut should be started.
As installed, both 'START_UPSD' and 'START_UPSMON' are set to no. Depending on
the configuration, these values will need to be changed.
For server fc1. |
# start upsd
START_UPSD=no
# start upsmon
START_UPSMON=yes
...
|
| For server fc2. |
# start upsd
START_UPSD=yes
# start upsmon
START_UPSMON=yes
...
|
|
| The instructions below are for the 'APCUPSD' package. |
- Login the server as root.
- Type: apt-get install apcupsd
- When requested, enter 'y' to continue the installation.
- If needed, install the requested Debian CD and press enter.
- Modify /etc/apcupsd/apcupsd.conf as needed to match the APC configuration.
- Modify /etc/default/apcupsd and change 'ISCONFIGURED" from no to yes.
- The configuration can be tested by entering: apcaccess status
- The log (located at: /var/log/apcupsd.events) should be reveiwed for any errors.
- The manual for this software is located at: apcupsd.org
