Milvus+ATTU环境搭建

1.使用Docker Compose安装Milvus Standalone

下载安装单机版milvus向量数据库 https://milvus.io/docs/install_standalone-docker.md

wget https://github.com/milvus-io/milvus/releases/download/v2.2.12/milvus-standalone-docker-compose.yml -O docker-compose.yml
sudo docker-compose up -d
# 连接到Milvus
docker port milvus-standalone 19530/tcp

2.启动和测试（可跳过）

2.1依赖安装：

pymilvus>=2.1.0
hnswlib>=0.5.2
pybind11
milvus>=2.1.0

2.2 下载示例代码进行测试

下载 hello_milvus.py 直接或使用以下命令

wget https://raw.githubusercontent.com/milvus-io/pymilvus/v2.2.8/examples/hello_milvus.pyorwget https://raw.githubusercontent.com/milvus-io/pymilvus/v2.2.x/examples/hello_milvus.py

运行 hello_milvus.py

python hello_milvus.py

attu 可视化详解

https://github.com/zilliztech/attu/blob/main/doc/zh-CN/attu_install-docker.md

docker run -p 8000:3000  -e MILVUS_URL={your machine IP}:19530 zilliz/attu:v2.2.6

使用用户名和密码连接到Milvus服务。

下载 `“milvus-standalone-docker-compose。并将其保存为“docker-compose”。手动或使用以下命令。

wget https://github.com/milvus-io/milvus/releases/download/v2.2.11/milvus-standalone-docker-compose.yml -O docker-compose.yml

编辑下载的“docker-compose”。使用您喜欢的文本编辑器将Yml '文件添加到services块中:

  attu:container_name: attuimage: zilliz/attu:v2.2.6environment:MILVUS_URL: milvus-standalone:19530ports:- "8000:3000"depends_on:- "standalone"

在与“docker-compose”文件相同的目录下。运行以下命令启动Milvus和Attu:

sudo docker-compose up -d

如果你的系统安装了Docker Compose V2而不是V1，使用’ Docker Compose ‘而不是’ Docker - Compose '。检查“$ docker compose version”是否属于这种情况。阅读这里了解更多信息。

Creating milvus-etcd  ... done
Creating milvus-minio ... done
Creating milvus-standalone ... done
Creating attu ... done

现在检查容器是否启动并运行。

sudo docker-compose ps

在Milvus standalone启动后，将有三个docker容器在运行，包括Milvus standalone服务和它的两个依赖项。
