+# Service with http-python
+
+## Server
+
+1. Install requirements
+
+```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。
