新特性

-- For deploy model cluster of DB-GPT(StorageModelRegistry)CREATE TABLE IF NOT EXISTS `dbgpt_cluster_registry_instance` (`id` int(11) NOT NULL AUTO_INCREMENT COMMENT 'Auto increment id',`model_name` varchar(128) NOT NULL COMMENT 'Model name',`host` varchar(128) NOT NULL COMMENT 'Host of the model',`port` int(11) NOT NULL COMMENT 'ort of the model',`weight` float DEFAULT 1.0 COMMENT 'Weight of the model',`check_healthy` tinyint(1) DEFAULT 1 COMMENT 'Whether to check the health of the model',`healthy` tinyint(1) DEFAULT 0 COMMENT 'Whether the model is healthy',`enabled` tinyint(1) DEFAULT 1 COMMENT 'Whether the model is enabled',`prompt_template` varchar(128) DEFAULT NULL COMMENT 'rompt template for the model instance',`last_heartbeat` datetime DEFAULT NULL COMMENT 'Last heartbeat time of the model instance',`user_name` varchar(128) DEFAULT NULL COMMENT 'User name',`sys_code` varchar(128) DEFAULT NULL COMMENT 'System code',`gmt_created` datetime DEFAULT CURRENT_TIMESTAMP COMMENT 'Record creation time',`gmt_modified` datetime DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT 'Record update time',PRIMARY KEY (`id`),UNIQUE KEY `uk_model_instance` (`model_name`, `host`, `port`, `sys_code`)) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COMMENT='Cluster model instance table, for registering and managing model instances';

2.我们需要在两台机器（server1和server2）上启动模型控制器，它们将通过连接到同一数据库来共享元数据。在 server1 上启动模型控制器：

dbgptstartcontroller\--port8000\--registry_typedatabase\--registry_db_typemysql\--registry_db_namedbgpt\--registry_db_host127.0.0.1\--registry_db_port3306\--registry_db_userroot\--registry_db_passwordaa123456

dbgptstartcontroller\--port8000\--registry_typedatabase\--registry_db_typemysql\--registry_db_namedbgpt\--registry_db_host127.0.0.1\--registry_db_port3306\--registry_db_userroot\--registry_db_passwordaa123456

3. 启动Model Worker

dbgptstartworker--model_nameglm-4-9b-chat\--model_path/app/models/glm-4-9b-chat\--port8001\--controller_addr"http://server1:8000,http://server2:8000"

4. 启动Embedding Model Worker

dbgptstartworker--model_nametext2vec\--model_path/app/models/text2vec-large-chinese\--worker_typetext2vec\--port8003\--controller_addr"http://server1:8000,http://server2:8000"

5. 启动Web Server

LLM_MODEL=glm-4-9b-chatEMBEDDING_MODEL=text2vec\dbgptstartwebserver\--light\--remote_embedding\--controller_addr"http://server1:8000,http://server2:8000"
