zfs(跳过)

(这一步跳过，新服务器只有一块盘，直接创建一个/data目录，权限777)
如何在 Ubuntu 上使用 ZFS 文件系统
安装 sudo apt install zfsutils-linux
创建 sudo zpool create your-pool raidz1 /dev/sdc /dev/sdd /dev/sde
raidz1就是拿一块盘做冗余，raidz3则是拿三块

avahi

服务器需要包含两个域名，mds-server.local和global-control.local 新服务器的临时ip是192.168.3.111，且未与采集工控机192.168.0.21连通所以需要脚本动态获取本机的ip地址

/usr/local/bin/avahi_publish.sh

#!/bin/bash

# 获取第一个非127.0.0.1的IPv4地址
IP=$(ip -4 addr show scope global | grep inet | awk '{print $2}' | cut -d/ -f1 | head -n1)

# 检查是否获取成功
if [ -z "$IP" ]; then
    echo "No valid IPv4 address found."
    exit 1
fi

# 启动avahi-publish（后台运行）
avahi-publish -a -R mds-server.local "$IP" &
avahi-publish -a -R global-control.local "$IP"

sudo apt upgrade -y
sudo apt install -y ca-certificates curl gnupg lsb-release
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
sudo docker run hello-world
docker compose version

遇到报错

$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": context deadline exceeded
Run 'docker run --help' for more information

更换国内加速器

sudo mkdir -p /etc/docker
sudo nano /etc/docker/daemon.json

daemon.json

{
  "registry-mirrors": ["https://docker.1ms.run"]
}

sudo systemctl daemon-reexec
sudo systemctl restart docker
sudo apt  install docker-compose

docker run运行成功

启动：在.yml文件路径下输入sudo docker-compose up -d

关闭： sudo docker-compose down

influxdb注册运行

启动之后，打开http://localhost:8086，设置用户名user，密码useruser，注册完毕得到token，将其改到docker-compose.yml中。

遇到telegraf的docker频繁重启，sudo docker logs telegraf查看日志

日志显示报错：telegraf.conf failed: error parsing data: line 2: invalid TOML syntax

TOML 格式要求严格，必须使用 标准 ASCII 空格和换行符，否则解析失败。

# 用 sed 自动替换非标准空格为标准空格
sed -i 's/ / /g' telegraf.conf

# 进一步验证配置正确性
telegraf --config telegraf.conf --test

待续。。。
