## 如何部署
|
||
|
||
### 初始化
|
||
|
||
**a. 初始化数据库**
|
||
|
||
* 创建数据库aideepin
|
||
* 执行docs/create.sql
|
||
* 填充各模型的配置(至少设置一个)
|
||
|
||
openai的secretKey
|
||
|
||
```plaintext
|
||
update adi_sys_config set value = '{"secret_key":"my_openai_secret_key","models":["gpt-3.5-turbo"]}' where name = 'openai_setting';
|
||
```
|
||
|
||
灵积大模型平台的apiKey
|
||
|
||
```plaintext
|
||
update adi_sys_config set value = '{"api_key":"my_dashcope_api_key","models":["my model name,eg:qwen-max"]}' where name = 'dashscope_setting';
|
||
```
|
||
|
||
千帆大模型平台的配置
|
||
|
||
```plaintext
|
||
update adi_sys_config set value = '{"api_key":"my_qianfan_api_key","secret_key":"my_qianfan_secret_key","models":["my model name,eg:ERNIE-Bot"]}' where name = 'qianfan_setting';
|
||
```
|
||
|
||
ollama的配置
|
||
|
||
```
|
||
update adi_sys_config set value = '{"base_url":"my_ollama_base_url","models":["my model name,eg:tinydolphin"]}' where name = 'ollama_setting';
|
||
```
|
||
|
||
* 填充搜索引擎的配置
|
||
|
||
Google的配置
|
||
|
||
```
|
||
update adi_sys_config set value = '{"url":"https://www.googleapis.com/customsearch/v1","key":"my key from cloud.google.com","cx":"my cx from programmablesearchengine.google.com"}' where name = 'google_setting';
|
||
```
|
||
|
||
|
||
**b. 修改配置文件**
|
||
|
||
* postgresql: application-[dev|prod].xml中的spring.datasource
|
||
* redis: application-[dev|prod].xml中的spring.data.redis
|
||
* mail: application.xml中的spring.mail
|
||
|
||
### 编译及运行
|
||
|
||
* 进入项目
|
||
|
||
```plaintext
|
||
cd langchain4j-aideepin
|
||
```
|
||
|
||
* 打包：
|
||
|
||
```
|
||
mvn clean package -Dmaven.test.skip=true
|
||
```
|
||
|
||
* 运行
|
||
|
||
a. jar包启动：
|
||
|
||
```plaintext
|
||
cd adi-bootstrap/target
|
||
nohup java -jar -Xms768m -Xmx1024m -XX:+HeapDumpOnOutOfMemoryError adi-chat-0.0.1-SNAPSHOT.jar --spring.profiles.active=[dev|prod] dev/null 2>&1 &
|
||
```
|
||
|
||
b. docker启动
|
||
|
||
```plaintext
|
||
cd adi-bootstrap
|
||
docker build . -t aideepin:0.0.1
|
||
docker run -d \
|
||
--name=aideepin \
|
||
-e APP_PROFILE=[dev|prod] \
|
||
-v="/data/aideepin/logs:/data/logs" \
|
||
aideepin:0.0.1
|
||
```
|
||
|
||
## 待办：
|
||
|
||
增强RAG
|
||
|
||
增加搜索引擎（BING、百度）
