1. UPS 配置
nut-scanner -qNU
[nutdev1]
driver = "usbhid-ups"
port = "auto"
vendorid = "051D"
productid = "0002"
product = "Back-UPS BK650M2-CH FW:294803G -292804G"
serial = "9B2123A10779"
vendor = "American Power Conversion"
bus = "003"
编辑 /etc/nut/ups.conf 文件，在文件最后增加：
参考：https://www.cnblogs.com/LandWind/articles/pve-nut-config.html
CPU 降频，编辑 /etc/default/cpufrequtils 文件，修改为如下：
ENABLE="true"
GOVERNOR="powersave"
MAX_SPEED="1.2"
MIN_SPEED="1.2GHz"
/etc/network/interfaces
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

2. dns
新增文件：/lib/systemd/system/ ，内容如下：
[Unit]
Description=Tencent DNS Service
After=network.target
StartLimitIntervalSec=500
StartLimitBurst=5
[Service]
Type=simple
# User=nobody
# Group=nobody
LimitNOFILE=32768
ExecStart=/usr/local/bin/tencent-dns
# PIDFile=/run/tencent-dns.pid
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=tencent-dns
Restart=on-failure
RestartSec=5s
[Install]
WantedBy=multi-user.target
将 tencent-dns 文件放至指定目录：
mv tencent-dns /usr/local/bin/tencent-dns
3. 更新源
4. 风扇配置
如果风扇不降速，声音非常响，常人是无法忍受的，因此需要通过 IPMI 将风扇降速。使用 crontab -e 新增如下项目：
@reboot echo "powersave" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor >/dev/null 2>&1
@reboot /usr/bin/ipmitool raw 0x30 0x70 0x66 0x01 0x00 0x3c
etc/apt/sources.list.d
/etc/apt/sources.list
apt update
apt update && apt dist-upgrade -y
apt-get -y install apcupsd
apt install -y ipmitool
