venv uvicorn python 虚拟服务器外网无法访问

本文主要是介绍venv uvicorn python 虚拟服务器外网无法访问，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

python -m venv .venv
source ./.venv/bin/activate
pip install -r requirements.txt
./run.sh

source ./.venv/bin/activate
uvicorn main:app --reload

虚拟web服务器外网访问控制台启动命令用以下代码启动
uvicorn main:app --host 0.0.0.0 --port 8501 --reload
启动到后台

nohup uvicorn main:app --host 0.0.0.0 --port 8501 --reload &
