fedora 安装apc smart750 UPS

一:概述#

我的家庭服务器是intel第一代NUC，渣渣配置，DE3815TYKHE

配置上挺惨的，尤其是处理器，采用了Bay Trail-I嵌入式系列的最低端型号Atom E3815，单核心单线程，主频1.46GHz，核心显卡HD Graphics 400MHz，内存支持单通道DDR3L-1066，热设计功耗5W，好处是完全不用风扇。

其他配置还有单条SO-DIMM内存插槽(最大容量8GB)、4GB eMMC闪存、2.5寸SATA硬盘位、半长式mini PCI-E扩展插槽、千兆以太网卡，接口方面提供USB 3.0、USB 2.0×2、VGA、HDMI等等，12-19V DC供电。

配了4G内存和一块淘汰的160G笔记本硬盘。凑活玩吧，反正已经赚回投资了。

安装的操作系统是fedora，由于各种异常断电…………问题，每年系统崩溃好几次。狠心配了个UPS apc smart750 。带有USB和串口管理功能。

配置需求大概是：停电后过多久，UPS关机，来电后过多久，UPS再打开输出。毕竟中国这电路虽然覆盖很广，停电很少，但是供电质量不行啊。

看，输入231.8V

二：试用#

在windows上安装apc的管理软件，并接好USB线缆，就可以设置了。

断电后转由电池供电60秒，即开始关机程序，为系统留下90秒时间进行关机，电力恢复延时60秒后再对UPS插座供电。

设计的是挺好，但是这个关机是真关机啊，还要有操作系统的反馈吧，不接USB通讯线，就不能关闭UPS。还得折腾fedora和UPS连接控制。

三：apcupsd#

apc也提供了linux版本的管理软件。也不知道是什么样的，看着应该也和windows差不多吧，可我的fedora是纯命令行的，估计没啥用。

dnf search apc 还真找到了第三方的apc UPS管理软件：http://www.apcupsd.org/

dnf install apcupsd 安装吧。

1.检查设备连接#

官方命令：

cat /proc/bus/usb/devices

fedora实际：

没这个文件

不纠结了，反正不耽误用。

2.启动测试#

systemctl start apcupsd

apcaccess

断开USB电缆

apcaccess

两次apcaccess的结果应该不一样，正常能看到UPS的型号信息如下：

systemctl enable apcupsd

把服务加入启动项。

3.配置EEPROM#

配置UPS存储EEPROM数据
Configuration Directives Used to Set the UPS EEPROM
These directives have no effect on the operation of apcupsd but are reserved for use by apctest when bulk programming the values of the UPS EEPROM configuration variables in a Smart-UPS model.

上次更换电池时间
BATTDATE [ mm/dd/yy | dd/mm/yy ]
Last battery replacement date. Maximum of 8 characters.

这个放在EEPROM中进行存储，省的你的记录不见。

配置方法是

停止apcupsd服务

systemctl stop apcupsd

运行配置程序

apctest

根据提示输入4

[root@nuc ~]# systemctl stop apcupsd
[root@nuc ~]# apctest

2020-04-24 04:16:06 apctest 3.14.14 (31 May 2016) redhat

还有6，关闭警告音，conf配置了没什么用，在eeprom里面配置吧。

然后推出，重启apcupsd服务

4.配置运行参数#

具体是配置/etc/apcpusd/apcpusd.conf文件

## apcupsd.conf v1.1 ##
# 
#  for apcupsd release 3.14.14 (31 May 2016) - redhat
#
# "apcupsd" POSIX config file
 
#
# Note that the apcupsd daemon must be restarted in order for changes to
# this configuration file to become active.
#
 
#
# ========= General configuration parameters ============
#
 
# UPSNAME xxx
#   Use this to give your UPS a name in log files and such. This
#   is particulary useful if you have multiple UPSes. This does not
#   set the EEPROM. It should be 8 characters or less.
UPSNAME UPS
 
# UPSCABLE <cable>
#   Defines the type of cable connecting the UPS to your computer.
#
#   Possible generic choices for <cable> are:
#     simple, smart, ether, usb
#
#   Or a specific cable model number may be used:
#     940-0119A, 940-0127A, 940-0128A, 940-0020B,
#     940-0020C, 940-0023A, 940-0024B, 940-0024C,
#     940-1524C, 940-0024G, 940-0095A, 940-0095B,
#     940-0095C, 940-0625A, M-04-02-2000
#
UPSCABLE usb
 
# To get apcupsd to work, in addition to defining the cable
# above, you must also define a UPSTYPE, which corresponds to
# the type of UPS you have (see the Description for more details).
# You must also specify a DEVICE, sometimes referred to as a port.
# For USB UPSes, please leave the DEVICE directive blank. For
# other UPS types, you must specify an appropriate port or address.
#
# UPSTYPE   DEVICE           Description
# apcsmart  /dev/tty**       Newer serial character device, appropriate for 
#                            SmartUPS models using a serial cable (not USB).
#
# usb       <BLANK>          Most new UPSes are USB. A blank DEVICE
#                            setting enables autodetection, which is
#                            the best choice for most installations.
#
# net       hostname:port    Network link to a master apcupsd through apcupsd's 
#                            Network Information Server. This is used if the
#                            UPS powering your computer is connected to a 
#                            different computer for monitoring.
#
# snmp      hostname:port:vendor:community
#                            SNMP network link to an SNMP-enabled UPS device.
#                            Hostname is the ip address or hostname of the UPS 
#                            on the network. Vendor can be can be "APC" or 
#                            "APC_NOTRAP". "APC_NOTRAP" will disable SNMP trap 
#                            catching; you usually want "APC". Port is usually 
#                            161. Community is usually "private".
#
# netsnmp   hostname:port:vendor:community
#                            OBSOLETE
#                            Same as SNMP above but requires use of the 
#                            net-snmp library. Unless you have a specific need
#                            for this old driver, you should use 'snmp' instead.
#
# dumb      /dev/tty**       Old serial character device for use with 
#                            simple-signaling UPSes.
#
# pcnet     ipaddr:username:passphrase:port
#                            PowerChute Network Shutdown protocol which can be 
#                            used as an alternative to SNMP with the AP9617 
#                            family of smart slot cards. ipaddr is the IP 
#                            address of the UPS management card. username and 
#                            passphrase are the credentials for which the card 
#                            has been configured. port is the port number on 
#                            which to listen for messages from the UPS, normally 
#                            3052. If this parameter is empty or missing, the 
#                            default of 3052 will be used.
#
# modbus    /dev/tty**       Serial device for use with newest SmartUPS models
#                            supporting the MODBUS protocol.
# modbus    <BLANK>          Leave the DEVICE setting blank for MODBUS over USB
#                            or set to the serial number of the UPS to ensure 
#                            that apcupsd binds to that particular unit
#                            (helpful if you have more than one USB UPS).
#
UPSTYPE usb
DEVICE 
 
# POLLTIME <int>
#   Interval (in seconds) at which apcupsd polls the UPS for status. This
#   setting applies both to directly-attached UPSes (UPSTYPE apcsmart, usb, 
#   dumb) and networked UPSes (UPSTYPE net, snmp). Lowering this setting
#   will improve apcupsd's responsiveness to certain events at the cost of
#   higher CPU utilization. The default of 60 is appropriate for most
#   situations.
#POLLTIME 60
 
# LOCKFILE <path to lockfile>
#   Path for device lock file. This is the directory into which the lock file
#   will be written. The directory must already exist; apcupsd will not create
#   it. The actual name of the lock file is computed from DEVICE.
#   Not used on Win32.
LOCKFILE /var/lock
 
# SCRIPTDIR <path to script directory>
#   Directory in which apccontrol and event scripts are located.
SCRIPTDIR /etc/apcupsd
 
# PWRFAILDIR <path to powerfail directory>
#   Directory in which to write the powerfail flag file. This file
#   is created when apcupsd initiates a system shutdown and is
#   checked in the OS halt scripts to determine if a killpower
#   (turning off UPS output power) is required.
PWRFAILDIR /etc/apcupsd
 
# NOLOGINDIR <path to nologin directory>
#   Directory in which to write the nologin file. The existence
#   of this flag file tells the OS to disallow new logins.
NOLOGINDIR /etc
 
 
#
# ======== Configuration parameters used during power failures ==========
#
 
# The ONBATTERYDELAY is the time in seconds from when a power failure
#   is detected until we react to it with an onbattery event.
#
#   This means that, apccontrol will be called with the powerout argument
#   immediately when a power failure is detected.  However, the
#   onbattery argument is passed to apccontrol only after the 
#   ONBATTERYDELAY time.  If you don't want to be annoyed by short
#   powerfailures, make sure that apccontrol powerout does nothing
#   i.e. comment out the wall.
ONBATTERYDELAY 6
 
# 
# Note: BATTERYLEVEL, MINUTES, and TIMEOUT work in conjunction, so
# the first that occurs will cause the initation of a shutdown.
#
 
# If during a power failure, the remaining battery percentage
# (as reported by the UPS) is below or equal to BATTERYLEVEL, 
# apcupsd will initiate a system shutdown.
BATTERYLEVEL 5
 
# If during a power failure, the remaining runtime in minutes 
# (as calculated internally by the UPS) is below or equal to MINUTES,
# apcupsd, will initiate a system shutdown.
MINUTES 3
 
# If during a power failure, the UPS has run on batteries for TIMEOUT
# many seconds or longer, apcupsd will initiate a system shutdown.
# A value of 0 disables this timer.
#
#  Note, if you have a Smart UPS, you will most likely want to disable
#    this timer by setting it to zero. That way, you UPS will continue
#    on batteries until either the % charge remaing drops to or below BATTERYLEVEL,
#    or the remaining battery runtime drops to or below MINUTES.  Of course,
#    if you are testing, setting this to 60 causes a quick system shutdown
#    if you pull the power plug.   
#  If you have an older dumb UPS, you will want to set this to less than
#    the time you know you can run on batteries.
TIMEOUT 30
 
#  Time in seconds between annoying users to signoff prior to
#  system shutdown. 0 disables.
ANNOY 300
 
# Initial delay after power failure before warning users to get
# off the system.
ANNOYDELAY 60
 
# The condition which determines when users are prevented from
# logging in during a power failure.
# NOLOGON <string> [ disable | timeout | percent | minutes | always ]
NOLOGON disable
 
# If KILLDELAY is non-zero, apcupsd will continue running after a
# shutdown has been requested, and after the specified time in
# seconds attempt to kill the power. This is for use on systems
# where apcupsd cannot regain control after a shutdown.
# KILLDELAY <seconds>  0 disables
KILLDELAY 0
 
#
# ==== Configuration statements for Network Information Server ====
#
 
# NETSERVER [ on | off ] on enables, off disables the network
#  information server. If netstatus is on, a network information
#  server process will be started for serving the STATUS and
#  EVENT data over the network (used by CGI programs).
NETSERVER on
 
# NISIP <dotted notation ip address>
#  IP address on which NIS server will listen for incoming connections.
#  This is useful if your server is multi-homed (has more than one
#  network interface and IP address). Default value is 0.0.0.0 which
#  means any incoming request will be serviced. Alternatively, you can
#  configure this setting to any specific IP address of your server and 
#  NIS will listen for connections only on that interface. Use the
#  loopback address (127.0.0.1) to accept connections only from the
#  local machine.
NISIP 0.0.0.0
 
# NISPORT <port> default is 3551 as registered with the IANA
#  port to use for sending STATUS and EVENTS data over the network.
#  It is not used unless NETSERVER is on. If you change this port,
#  you will need to change the corresponding value in the cgi directory
#  and rebuild the cgi programs.
NISPORT 3551
 
# If you want the last few EVENTS to be available over the network
# by the network information server, you must define an EVENTSFILE.
EVENTSFILE /var/log/apcupsd.events
 
# EVENTSFILEMAX <kilobytes>
#  By default, the size of the EVENTSFILE will be not be allowed to exceed
#  10 kilobytes.  When the file grows beyond this limit, older EVENTS will
#  be removed from the beginning of the file (first in first out).  The
#  parameter EVENTSFILEMAX can be set to a different kilobyte value, or set
#  to zero to allow the EVENTSFILE to grow without limit.
EVENTSFILEMAX 10
 
#
# ========== Configuration statements used if sharing =============
#            a UPS with more than one machine
 
#
# Remaining items are for ShareUPS (APC expansion card) ONLY
#
 
# UPSCLASS [ standalone | shareslave | sharemaster ]
#   Normally standalone unless you share an UPS using an APC ShareUPS
#   card.
UPSCLASS standalone
 
# UPSMODE [ disable | share ]
#   Normally disable unless you share an UPS using an APC ShareUPS card.
UPSMODE disable
 
#
# ===== Configuration statements to control apcupsd system logging ========
#
 
# Time interval in seconds between writing the STATUS file; 0 disables
STATTIME 0
 
# Location of STATUS file (written to only if STATTIME is non-zero)
STATFILE /var/log/apcupsd.status
 
# LOGSTATS [ on | off ] on enables, off disables
# Note! This generates a lot of output, so if         
#       you turn this on, be sure that the
#       file defined in syslog.conf for LOG_NOTICE is a named pipe.
#  You probably do not want this on.
LOGSTATS off
 
# Time interval in seconds between writing the DATA records to
#   the log file. 0 disables.
DATATIME 0
 
# FACILITY defines the logging facility (class) for logging to syslog. 
#          If not specified, it defaults to "daemon". This is useful 
#          if you want to separate the data logged by apcupsd from other
#          programs.
#FACILITY DAEMON
 
#
# ========== Configuration statements used in updating the UPS EPROM =========
#
 
#
# These statements are used only by apctest when choosing "Set EEPROM with conf
# file values" from the EEPROM menu. THESE STATEMENTS HAVE NO EFFECT ON APCUPSD.
#

# To get apcupsd to work, in addition to defining the cable
# above, you must also define a UPSTYPE, which corresponds to
# the type of UPS you have (see the Description for more details).
# You must also specify a DEVICE, sometimes referred to as a port.
# For USB UPSes, please leave the DEVICE directive blank. For
# other UPS types, you must specify an appropriate port or address.
#
# UPSTYPE DEVICE Description
# apcsmart /dev/tty** Newer serial character device, appropriate for
# SmartUPS models using a serial cable (not USB).
#
# usb <BLANK> Most new UPSes are USB. A blank DEVICE
# setting enables autodetection, which is
# the best choice for most installations.
#
# net hostname:port Network link to a master apcupsd through apcupsd's
# Network Information Server. This is used if the
# UPS powering your computer is connected to a
# different computer for monitoring.
#
# snmp hostname:port:vendor:community
# SNMP network link to an SNMP-enabled UPS device.
# Hostname is the ip address or hostname of the UPS
# on the network. Vendor can be can be "APC" or
# "APC_NOTRAP". "APC_NOTRAP" will disable SNMP trap
# catching; you usually want "APC". Port is usually
# 161. Community is usually "private".
#
# netsnmp hostname:port:vendor:community
# OBSOLETE
# Same as SNMP above but requires use of the
# net-snmp library. Unless you have a specific need
# for this old driver, you should use 'snmp' instead.
#
# dumb /dev/tty** Old serial character device for use with
# simple-signaling UPSes.
#
# pcnet ipaddr:username:passphrase:port
# PowerChute Network Shutdown protocol which can be
# used as an alternative to SNMP with the AP9617
# family of smart slot cards. ipaddr is the IP
# address of the UPS management card. username and
# passphrase are the credentials for which the card
# has been configured. port is the port number on
# which to listen for messages from the UPS, normally
# 3052. If this parameter is empty or missing, the
# default of 3052 will be used.
#
# modbus /dev/tty** Serial device for use with newest SmartUPS models
# supporting the MODBUS protocol.
# modbus <BLANK> Leave the DEVICE setting blank for MODBUS over USB
# or set to the serial number of the UPS to ensure
# that apcupsd binds to that particular unit
# (helpful if you have more than one USB UPS).

DEVICE

# If during a power failure, the remaining battery percentage
# (as reported by the UPS) is below or equal to BATTERYLEVEL,
# apcupsd will initiate a system shutdown.
BATTERYLEVEL 5

# If during a power failure, the remaining runtime in minutes
# (as calculated internally by the UPS) is below or equal to MINUTES,
# apcupsd, will initiate a system shutdown.
MINUTES 3

# If during a power failure, the UPS has run on batteries for TIMEOUT
# many seconds or longer, apcupsd will initiate a system shutdown.
# A value of 0 disables this timer.
#
# Note, if you have a Smart UPS, you will most likely want to disable
# this timer by setting it to zero. That way, you UPS will continue
# on batteries until either the % charge remaing drops to or below BATTERYLEVEL,
# or the remaining battery runtime drops to or below MINUTES. Of course,
# if you are testing, setting this to 60 causes a quick system shutdown
# if you pull the power plug.
# If you have an older dumb UPS, you will want to set this to less than
# the time you know you can run on batteries.
TIMEOUT 30

# UPS delay after power return (seconds)
# WAKEUP 000 060 180 300 (default = 0)
WAKEUP 60

# UPS Grace period after request to power off (seconds)
# SLEEP 020 180 300 600 (default = 20)
SLEEP 180

# Battery charge needed to restore power
# RETURNCHARGE 00 15 50 90 (default = 15)
RETURNCHARGE 50

# Alarm delay
# 0 = zero delay after pwr fail, T = power fail + 30 sec, L = low battery, N = never
# BEEPSTATE 0 T L N (default = 0)
BEEPSTATE L

# Low battery warning delay in minutes
# LOWBATT 02 05 07 10 (default = 02)
LOWBATT 10
