Milvus-standalone部署在centos上

一、Milvus-standalone 版安装

 

下载docker-compose配置文件

wget https://github.com/milvus-io/milvus/releases/download/v2.5.5/milvus-standalone-docker-compose.yml -O docker-compose.yml 

 

因要对外提供服务，修改ymal配置文件的默认服务端口号：

  minio: 9000->22000, 9001->22001;  etcd: 修改为单机模式运行(开始没改导致etcd集群未检测到其余结点而报错，折腾半天)；   milvus-standalone: 19530->29530, 9091->29091

version: '3.5'
​
services:
  etcd:
    container_name: milvus-etcd
    image: quay.io/coreos/etcd:v3.5.18
    environment:
      - ETCD_AUTO_COMPACTION_MODE=revision
      - ETCD_AUTO_COMPACTION_RETENTION=1000
      - ETCD_QUOTA_BACKEND_BYTES=4294967296
      - ETCD_SNAPSHOT_COUNT=50000
    volumes:
      - ${DOCKER_VOLUME_DIRECTORY:-.}/volumes/etcd:/etcd
    command: etcd -advertise-client-urls=http://etcd:2379 -listen-client-urls http://0.0.0.0:2379 --data-dir /etcd
    healthcheck:
      test: ["CMD", "etcdctl", "endpoint", "health"]
      interval: 30s
      timeout: 20s
      retries: 3
​
  minio:
    container_name: milvus-minio
    image: minio/minio:RELEASE.2023-03-20T20-16-18Z
    environment:
      MINIO_ACCESS_KEY: minioadmin
      MINIO_SECRET_KEY: minioadmin
    ports:
      - "22001:9001"
      - "22000:9000"
    volumes:
      - ${DOCKER_VOLUME_DIRECTORY:-.}/volumes/minio:/minio_data
    command: minio server /minio_data --console-address ":22001"
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
      interval: 30s
      timeout: 20s
      retries: 3
​
  standalone:
    container_name: milvus-standalone
    image: milvusdb/milvus:v2.5.5
    command: ["milvus", "run", "standalone"]
    security_opt:
    - seccomp:unconfined
    environment:
      ETCD_ENDPOINTS: etcd:2379
      MINIO_ADDRESS: minio:9000
    volumes:
      - ${DOCKER_VOLUME_DIRECTORY:-.}/volumes/milvus:/var/lib/milvus
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9091/healthz"]
      interval: 30s
      start_period: 90s
      timeout: 20s
      retries: 3
    ports:
      - "29530:19530"
      - "29091:9091"
    depends_on:
      - "etcd"
      - "minio"
​
networks:
  default:
    name: milvus
​

 

启动Milvus，需要说明的是所有数据都是保存在 ./volumes/ 目录内的

# milvus- standalone、milvus-minio 和milvus-etcd 容器启动
sudo docker-compose up -d
docker-compose ps

 

停止Milvus

sudo docker-compose down 

 

删除Milvus数据

 sudo rm -rf volumes

 

 

二、数据保存目录：

1、milvus-etcd容器不向主机暴露任何端口，并将其数据映射到当前文件夹中的volumes/etcd。 ​

2、milvus-minio容器使用默认身份验证凭据在本地为端口9090和9091提供服务，并将其数据映射到当前文件夹中的volumes/minio。 ​

3、Milvus-standalone容器使用默认设置为本地19530端口提供服务，并将其数据映射到当前文件夹中的volumes/milvus。

UI访问：http://127.0.0.1:22091/webui/

 

三、测试功能：用python创建一个数据库

from pymilvus import connections, db

conn = connections.connect(host="127.0.0.1", port=19530)
database = db.create_database("my_database")

创建成功，如下图：

  至此部署完成。
