2. 安装

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

3. 访问
   webui

# http://192.168.3.75:9091/webui

接口19530
4. 设置鉴权
默认无需鉴权
设置鉴权参考
https://blog.csdn.net/zhilaizhiwang/article/details/141395202

• 通过docker容器id从容器内拷贝配置文件

# docker cp milvus.yaml  b459e5d7a4eb:/milvus/configs/milvus.yaml

• 修改配置文件
  
• 使用python代码修改密码
  需要先安装模块

# pip install pymilvus

使用以下代码修改密码

from pymilvus import MilvusClient
#连接
client = MilvusClient(
    uri='http://localhost:19530', # replace with your own Milvus server address
    token="root:Milvus"
) 
#修改密码
client.update_password(
    user_name="root",
    old_password="Milvus",
    new_password="password"
)
#创建新用户
client.create_user(
    user_name="user_1",
    password="P@ssw0rd",
)
client.describe_user("user_1")

连接测试
创建数据库

# 导入模块
>>> from pymilvus import connections, db
# 连接数据库 
# 如果没有设置鉴权则无需user和password参数
# 如果设置鉴权则必须有且输入正确 否则会报错
>>> conn = connections.connect(host="127.0.0.1", port=19530, user="root", password="password")
# 创建数据库
>>> database = db.create_database("my_database")
# 列出所有数据库
>>> db.list_database()
['default', 'my_database']
