2022-11-17 山特UPS-Ubuntu断电自动关机 - 来电自动开机
1.安装 nut
apt-get install nut
2.使用lsusb查看是否接入ups
lsusb
# 如果没有装一个 lsusb
apt-get install lsusb
3.配置驱动
# 1.编辑ups配置文件 sudo vim /etc/nut/ups.conf,增加配置如下sudo vim /etc/nut/ups.confmaxretry = 3
[sanups]
driver = usbhid-ups
port = auto
desc = "dev ups"
4.配置nut服务
# 1.新建ups用户sudo vim /etc/nut/upsd.users# 1.1 新增配置
[ups]
password = 123456
upsmon master
# 2.配置权限 chown root:nut /etc/nut/upsd.conf /etc/nut/upsd.users
chmod0640 /etc/nut/upsd.conf /etc/nut/upsd.users
# 3.修改模式为单机 sudo vim /etc/nut/nut.conf# 3.1 增加配置
MODE=standalone
5.启动服务
# 1.启动upsd服务
sudo /sbin/upsd
# 2.查看启动服务信息 /bin/upsc sanups@localhost# ups.conf中的设备名
# 3.查看电量
/bin/upsc sanups@127.0.0.1 battery.charge
6.设置自动关机
# 当电量剩余20%时, nut服务会ups发送LOWBATT时通知机器关机
# 1. 配置upsmon
sudo vim /etc/nut/upsmon.conf
# 2.配置权限sudo chown root:nut /etc/nut/upsmon.conf
sudo chmod0640 /etc/nut/upsmon.conf
# 3.启动upsmon
sudo /sbin/upsmon
7.配置高级电源策略-自定义事件（upssched）
# 自定义触发事件, 断电时自动关机
# 1. 配置运行upssched程序
sudo vim /etc/nut/upsmon.conf
# 1.1 新增配置
# 触发条件,三个动作: 记录日志+通知用户事件+执行notifycmd
NOTIFYCMD /sbin/upssched
NOTIFYFLAG ONBATT SYSLOG+WALL+EXEC
# 2.配置upsschedsudo vim /etc/nut/upssched.conf# 2.1 新增配置CMDSCRIPT /usr/local/bin/upssched
PIPEFN /usr/local/bin/nut/upssched/upssched.pipe
LOCKFN /usr/local/bin/nut/upssched/upssched.lock
AT ONBATT * START-TIMER power-off300 # 300秒后自动关机 AT ONLINE * CANCEL-TIMER power-off
AT ONLINE * EXECUTE power-on
8.配置事件触发脚本
# 1.配置触发脚本
sudo vim /usr/local/bin/upssched
# 1.1 新增脚本
#!/bin/bash
case $1in
power-off)
/sbin/upsmon -c fsd
;;
*)
logger -t upssched "Unrecognized command: $1"
;;
esac
# 1.2 邮件发送停电通知 (mail发邮件要记得装mail包哦!!!)
# 1.2.1/sbin/upsmon -c fsd执行立刻关机操作 (FSD = "Forced Shutdown")
#!/bin/bash
case $1in
power-off)
echo "The UPS has been on battery for 300 seconds and foreman is about to shut down." \ | mail -s "NUT Master is about to shut down" lin@mail.com
/sbin/upsmon -c fsd
;;
power-on)
echo "The UPS is online now and the server has started." \
| mail -s "NUT Master has started" lin@mail.com
;;
*)logger -t upssched"Unrecognized command: $1"
;;
esac
9.来电自动开机(以Dell服务器为例)
# 1.在开机过程中按键盘"F12",进入选择“BIOS SETUP”;
# 2.选择“Power Management”;
# 3.选择“AC Recovery”，点选“Power On”，点击“Apply”;
# 4.勾选“Save as Custom User Setting”,点击OK;
# 5.点击“EXit”退出即可;
# 6.配置完成, 重新上电自动重启;
9.断电测试
# 重启一下
sudo /sbin/upsmon -s reload
# 1. 断开UPS电源
# 2. 查看状态
sudo systemctl status nut-client
# 3.查看控制台是否弹出通知
# 4.插上UPS电源
# 5.查看控制台是否弹出电源恢复通知
# 6.断电来电测试
