# Service with http-python
## Server

```shell
cd funasr/runtime/python/http
pip install -r requirements.txt
```
2. Start server
```shell
python server.py --port 8000
```
More parameters:
```shell
python server.py \
--host [host ip] \
--port [server port] \
--asr_model [asr model_name] \
--vad_model [vad model_name] \
--punc_model [punc model_name] \
--device [cuda or cpu] \
--ngpu [0 or 1] \
--ncpu [1 or 4] \
--hotword_path [path of hot word txt] \
--certfile [path of certfile for ssl] \
--keyfile [path of keyfile for ssl] \
--temp_dir [upload file temp dir]
```
## Client
```shell
# get test audio file
wget https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_audio/asr_example_zh.wav
python client.py --host=127.0.0.1 --port=8000 --audio_path=asr_example_zh.wav
```
More parameters:
```shell
python server.py \
--host [sever ip] \
--port [sever port] \
--audio_path [use audio path]
```
## 支持多进程
方法是启动多个`server.py`然后通过Nginx的负载均衡分发请求达到支持多用户同时连效果处理方式如下默认您已经安装了Nginx没安装的请参考[官方安装教程](https://nginx.org/en/linux_packages.html#Ubuntu)。
配置Nginx。
```shell
sudo cp -f asr_nginx.conf /etc/nginx/nginx.conf
sudo service nginx reload
```
然后使用脚本启动多个服务,每个服务的端口号不一样。
```shell
sudo chmod +x start_server.sh
./start_server.sh
```
**说明:** 默认是3个进程如果需要修改首先修改`start_server.sh`的最后那部分,可以添加启动数量。然后修改`asr_nginx.conf`配置文件的`upstream backend`部分,增加新启动的服务,可以使其他服务器的服务。
