fedora 安装apc smart750 UPS
<h2>一:概述</h2><p>我的家庭服务器是intel第一代NUC，渣渣配置，<strong>DE3815TYKHE </strong></p>
<p>配置上挺惨的，尤其是处理器，<strong>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。</strong></p>
<p>其他配置还有<strong>单条SO-DIMM内存插槽(最大容量8GB)、4GB eMMC闪存、2.5寸SATA硬盘位</strong>、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。</p>
<p>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。</p>
<p>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。</p>
<p>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。</p>
<p>看，输入231.8V</p>

<h2>二：试用</h2>
<p>在windows上安装apc的管理软件，并接好USB线缆，就可以设置了。</p>
<p>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。</p>
<p><img src="https://img2020.cnblogs.com/blog/1241143/202004/1241143-20200424074619004-1666108749.png" alt=""></p>
<p> </p>
<p>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。</p>
<h2>三：apcupsd</h2>
<p>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。</p>
<p>dnf search apc 还真找到了第三方的apc UPS管理软件：http://www.apcupsd.org/</p>
<p>dnf install apcupsd 安装吧。</p>
<h3>1.检查设备连接</h3>
<p>官方命令：</p>
<pre class="literal-block">cat /proc/bus/usb/devices</pre>
<p>fedora实际：</p>
<pre class="literal-block">没这个文件</pre>
<p>不纠结了，反正不耽误用。</p>
<p> </p>
<h3> 2.启动测试</h3>
<p>systemctl start apcupsd </p>
<p>apcaccess</p>
<p>断开USB电缆</p>
<p>apcaccess</p>
<p>两次apcaccess的结果应该不一样，正常能看到UPS的型号信息如下：</p>

<p>这个放在EEPROM中进行存储，省的你的记录不见。</p>
<p> </p>
<p>配置方法是</p>
<p>停止apcupsd服务</p>
<p>systemctl stop apcupsd</p>
<p>运行配置程序</p>
<p>apctest</p>
<p>根据提示输入4</p>
<p>4</p>

<p>还有6，关闭警告音，conf配置了没什么用，在eeprom里面配置吧。</p>
<p> </p>
<p>然后推出，重启apcupsd服务</p>
<h3>4.配置运行参数</h3>
<p>具体是配置/etc/apcpusd/apcpusd.conf文件</p>
<div class="cnblogs_Highlighter">
<pre class="brush:bash;collapse:true;;gutter:true;">## 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,

# 940-0095C, 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.
#
# UPS name, max 8 characters
