停電対策としてApcupsd 3.14.8をインストールした時のメモ。
- Vine Linux 5.0
- Apcupsd 3.14.8
- APC Smart-UPS750JB
まずはApcupsdのサイトからtar玉を落としてくる。
$ cd /usr/local/src $ tar zxvf apcupsd-3.14.8.tar.gz
で、うちのはAPC Smart-UPS用USBケーブルでUPSに接続していて、状態をブラウザで確認したいのでCGIも通す。
$ cd apcupsd-3.14.8 $ ./configure \ --enable-usb --with-upstype=usb --with-upscable=usb \ --enable-cgi --with-cgi-bin=/var/www/cgi-bin/apcupsd \ --with-log-dir=/var/log
makeしてinstall。
$ su # make install
電源異常が起こった際のシャットダウン動作までの閾値を設定をする。
一時的な停電(瞬断)対策としてバッテリーでの給電開始後10秒は様子を見るが、10秒経っても電源が回復しない場合は電源異常(停電)とみなし、
- バッテリーの残量が30%
- 稼働可能時間が残り20分
のいずれかの閾値に達した場合、サーバをシャットダウンさせるようにする。
# vi /etc/apcupsd/apcupsd.conf
## apcupsd.conf v1.1 ## # # for apcupsd release 3.14.8 (16 January 2010) - Vine 5.0 # # "apcupsd" POSIX config file # # ========= 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 SUA750-1 UPSの識別名 # 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, 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 # 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 mgmtcard. username and # passphrase are the credentials for which the card # has been configured. # 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. 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 10 瞬断の閾値(10秒) # # 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 30 バッテリー残の閾値(30%) # 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 20 残り稼働時間の閾値(20分) # 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 0 # 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.

後はシャットダウン後に電源が復帰すると自動でサーバが起動するように、BIOSの電源設定でAllways ONとしておく。
その後電源タップのスイッチを切り、実際に電源異常の状態を作ってテストをする。
