概述
部署使用了Nginx+Supervisor+Gunicorn+Uvicorn
域名与后端服务可以在同一个服务器，也可以在不同的服务器
服务挂载在9000端口，域名的/api/mysite/用于对外提供后端接口服务
1. Python文件的Demo
# main.py
from fastapi import FastAPI, Request
from fastapi.responses import RedirectResponse
app = FastAPI(root_path='/api/mysite')
@app.get('/app')
async def some_request_info(request: Request):
return {'root_path': request.scope.get('root_path'),'url': request.url, 'headers': request.headers}
@app.get('/', include_in_schema=False)
async def home(request: Request):
"""首页自动跳转到 /docs"""
return RedirectResponse(request.app.root_path + '/docs')
def docs_monkey_patch_for_root_path(app: FastAPI) -> None:
# 用于解决app增加root_path后，本地docs不能访问的问题
@app.get(app.root_path+'/{path:path}', include_in_schema=False)
@app.post(app.root_path+'/{path:path}', include_in_schema=False)
async def redirect_docs(path: str):
return RedirectResponse('/' + path)
docs_monkey_patch_for_root_path(app)
2. supervisor配置
[program:mysite]
environment =
SENTRY_ID=a5b4df500281a963532180a68616b7d6,
START_SENTRY=1
command=poetry run gunicorn main:app --workers 2 --worker-class uvicorn.workers.UvicornWorker --bind 0.0.0.0:9000
directory=/home/ubuntu/coding/mysite
stdout_logfile=/home/ubuntu/coding/mysite/supervisor.log
user=ubuntu
numprocs=1
autostart=true
startsecs=10
autorestart=true
startretried=3
redirect_stderr=true
stdout_logfile_maxbytes=20MB
stdout_logfile_backups=20
3. nginx配置
upstream mysite_api {
# 如果不是在同一个服务器，则把127.0.0.1改成对应的服务器IP
server 127.0.0.1:9817;
}
server {
...
location /api {
rewrite ^/api/mysite/(.*) /$1 break;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://mysite_api;
}
}
