企业官网建设流程全解析

一、Milvus简介

Milvus（Milvus | High-Performance Vector Database Built for Scale，https://milvus.io/，官网https://milvus.io/） 是由 Zilliz 公司开发的‌开源向量数据库‌，专为高效处理非结构化数据（如图像、视频、音频）的向量化存储与检索而设计‌。它采用云原生架构，支持存储计算分离和 Kubernetes 部署，能弹性扩展至百亿级向量规模‌。

核心特性

1. ‌高性能检索‌
   支持 GPU 加速和多种索引算法（如 CAGRA、HNSW），实现毫秒级近似最近邻搜索‌。例如三维向量相似性搜索可快速定位最接近目标的数据点‌。

2. ‌混合查询能力‌
   支持同时筛选向量相似度和结构化字段，如查找相似图片时限定特定类别标签‌

3. ‌开发友好性‌
4. 提供 Python/Java/Go 等多语言 SDK
5. 轻量版 Milvus Lite 支持pip install快速部署‌
6. 兼容 PyTorch 等主流框架

应用场景

• ‌非结构化数据‌：如文本、语音、图像、视频等，通过嵌入技术转化为向量后存储。 ‌
• ‌人工智能‌：在聊天机器人、网络搜索等场景中实现相似度检索。 ‌

架构特点

• ‌分层设计‌：分为接入层、协调服务层、工作节点和存储层，各层独立扩展和容灾。
• ‌共享存储‌：计算节点与存储分离，支持数据持久化和增量数据摄取

二、环境准备

Ubuntu 22.04.5 LTS (GNU/Linux 5.15.0-144-generic x86_64)

2.1.配置soures.list，可以直接去编辑/etc/apt/sources.list，也可以参考下面的命令

#将主软件源地址替换为阿里云镜像 sudo sed -i 's/archive.ubuntu.com/mirrors.aliyun.com/g' /etc/apt/sources.list #将安全更新源替换为阿里云镜像 sudo sed -i 's/security.ubuntu.com/mirrors.aliyun.com/g' /etc/apt/sources.list sudo apt-get update

2.2.安装docker

2.2.1.下载docker的deb

wget https://mirrors.huaweicloud.com/docker-ce/linux/ubuntu/dists/jammy/pool/stable/amd64/containerd.io_1.7.26-1_amd64.deb wget https://mirrors.huaweicloud.com/docker-ce/linux/ubuntu/dists/jammy/pool/stable/amd64/docker-ce_28.0.2-1~ubuntu.22.04~jammy_amd64.deb wget https://mirrors.huaweicloud.com/docker-ce/linux/ubuntu/dists/jammy/pool/stable/amd64/docker-ce-cli_28.0.2-1~ubuntu.22.04~jammy_amd64.deb wget https://mirrors.huaweicloud.com/docker-ce/linux/ubuntu/dists/jammy/pool/stable/amd64/docker-buildx-plugin_0.22.0-1~ubuntu.22.04~jammy_amd64.deb wget https://mirrors.huaweicloud.com/docker-ce/linux/ubuntu/dists/jammy/pool/stable/amd64/docker-compose-plugin_2.34.0-1~ubuntu.22.04~jammy_amd64.deb

2.2.2.安装docker命令如下：

dpkg -i ./containerd.io_1.7.26-1_amd64.deb ./docker-ce_28.0.2-1~ubuntu.22.04~jammy_amd64.deb ./docker-ce-cli_28.0.2-1~ubuntu.22.04~jammy_amd64.deb ./docker-buildx-plugin_0.22.0-1~ubuntu.22.04~jammy_amd64.deb ./docker-compose-plugin_2.34.0-1~ubuntu.22.04~jammy_amd64.deb #或者命令 dpkg -i *.deb

安装后的版本信息如下

docker compose version #Docker Compose version v2.34.0 docker version #Client: Docker Engine - Community # Version: 28.0.2 # API version: 1.48 # Go version: go1.23.7 # Git commit: 0442a73 # Built: Wed Mar 19 14:36:46 2025 # OS/Arch: linux/amd64 # Context: default # #Server: Docker Engine - Community # Engine: # Version: 28.0.2 # API version: 1.48 (minimum version 1.24) # Go version: go1.23.7 # Git commit: bea4de2 # Built: Wed Mar 19 14:36:46 2025 # OS/Arch: linux/amd64 # Experimental: false # containerd: # Version: 1.7.26 # GitCommit: 753481ec61c7c8955a23d6ff7bc8e4daed455734 # runc: # Version: 1.2.5 # GitCommit: v1.2.5-0-g59923ef # docker-init: # Version: 0.19.0 # GitCommit: de40ad0

2.3.3 配置/etc/docker/daemon.json

#cat /etc/docker/daemon.json { "registry-mirrors": [ "https://docker.m.daocloud.io", "https://docker.nju.edu.cn", "https://hub-mirror.c.163.com", "https://registry.docker-cn.com" ] } #重启docker systemctl restart docker || service docker restart #查看docker运行状态 systemctl status docker #●docker.service - Docker Application Container Engine # Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: #enabled) # Active: active (running) since Mon 2025-08-18 08:42:46 CST; 1h 19min ago #TriggeredBy: ● docker.socket

三、安装Milvus

3.1.1下载脚本

curl -sfL https://raw.githubusercontent.com/milvus-io/milvus/master/scripts/standalone_embed.sh -o standalone_embed.sh

3.1.2 运行

./standalone_embed.sh start #Milvus is running.

遇到的问题：

错误1：/standalone_embed.sh start

#./standalone_embed.sh please use bash standalone_embed.sh restart|start|stop|upgrade|delete root@iZ2zefmyqi46e90ttn3odtZ:~/docker# ./standalone_embed.sh start Unable to find image 'milvusdb/milvus:v2.6.0' locally docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": context deadline exceeded Run 'docker run --help' for more information Start failed.

原因是/ /etc/docker/daemon.json里面配置的源地址不能用，建议采用科学上网的模式，因为那些镜像的服务器说不定哪天会抽风。修改daemon.json文件后，需要重启一下服务

sudo systemctl daemon-reload sudo systemctl restart docker sudo systemctl status docker

问题2：如果打不开，自己新建一个standalone_embed.sh
