gunicorn 和 uvicorn一起部署fastapi 或者flask

• 安装需要的包
• 后台代码
• 启动
• 可能遇到的问题

安装需要的包

pip install gunicorn uvicorn greenlet  eventlet gevent

后台代码

Server.py 文件中有app 变量

启动

# http 服务 timeout 单位s
gunicorn -k uvicorn.workers.UvicornWorker    Server:app --bind 0.0.0.0:5665 --workers 2 --timeout 100

# https 服务
gunicorn -k uvicorn.workers.UvicornWorker  --certfile=./configs/a.pem --keyfile=./configs/a-key.pem  Server:app --bind 0.0.0.0:5665 --workers 2 --timeout 520 

可能遇到的问题

如果遇到报错

Error: class uri 'uvicorn.workers.UvicornWorker' invalid or not found:

[Traceback (most recent call last):

File "/usr/lib/python2.7/site-packages/gunicorn/util.py", line 135, in load_class

mod = import_module('.'.join(components))

File "/usr/lib64/python2.7/importlib/init .py", line 37, in import_module
import (name)

ImportError: No module named uvicorn.workers

]

是因为环境中gunicorn 有冲突，需要指定安装环境的gunicorn

 /your_env_path/anaconda3/envs/your_env_name/bin/gunicorn -k uvicorn.workers.UvicornWorker  --certfile=./configs/a.pem --keyfile=./configs/a-key.pem  imageSegSimServer:app --bind 0.0.0.0:5665 --workers 2 --timeout 520
