如何在 apache2 上运行 FastAPI？

Question

我已经使用 fastapi 开发了一个 api，它将充当接收短信请求并调用短信 api 发送所述短信的包装器，现在我是准备部署它。这是代码：

import logging

import uvicorn
from fastapi import FastAPI, HTTPException
from pydantic import BaseModel
from fastapi.middleware.trustedhost import TrustedHostMiddleware

import verifier

logging.basicConfig(
    format='%(asctime)s - %(funcName)s - %(levelname)s - %(message)s',
    level=logging.INFO
)

# get logger
logger = logging.getLogger(__name__)


bot_verifier = None


class DataForBot(BaseModel):
    number: str
    msg_txt: str


def get_application():
    app = FastAPI(title='bot_wrapper', version="1.0.0")

    return app


app = get_application()


@app.on_event("startup")
async def startup_event():
    global bot_verifier
    try:
        bot_verifier = await verifier.Verifier.create()
    except Exception as e:
        logger.error(f"exception occured during bot creation -- {e}", exc_info=True)


@app.post('/telegram_sender/')
async def send_telegram_msg(data_for_bot: DataForBot):
    global bot_verifier
    if not bot_verifier:
        bot_verifier = await verifier.Verifier.create()
    else:
        dict_data = data_for_bot.dict()
        try:
            if await bot_verifier.send_via_telegram(dict_data):
                return {'status': "success", 'data': data_for_bot}
            else:
                raise HTTPException(status_code=404, detail="unable to send via telegram, perhaps user has not started the bot")
        except Exception as e:
            logger.error(f"{e}", exc_info=True)
            raise HTTPException(status_code=500, detail="Something went wrong, please contact server admin")

我想将它部署在 apache 上 b/c 在我的国家，这是我唯一能得到的东西。我将 python3.8.9 与 fastapi 版本 0.65.2 和 apache/2.4.29 一起使用，但对于我来说，我无法让它工作。我已经编写了一个 apache conf 文件并启用了它：

<VirtualHost *:80>
    ServerName gargarsa.sms.local
    ServerAdmin webmaster@localhost
    ServerAlias gargarsa.sms.local
    
    DocumentRoot /var/www/verify_bot_api/
    ServerAlias gargarsa.sms.local

    <Directory /var/www/verify_bot_api/src/app/>
        Order deny,allow
        Allow from all
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/gargarsa.sms.local-error.log
    LogLevel debug
    CustomLog ${APACHE_LOG_DIR}/gargarsa.sms.local-access.log combined
</VirtualHost>

但无济于事。

我尝试通过屏幕会话运行ning gunicorn，但我也无法访问它。

我试过运行以编程方式对其进行设置，但无济于事：

if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=8000)

我知道这是一个非常宽泛的提问方式，但我真的很困惑。

如何运行在 Apache2 上使用 fastapi 构建 api？

感谢您的帮助。

Answer 1

以防万一其他人在这里偶然发现，这就是我所做的，这就是它对我有用的方式。这是关于 b/c 网上没有太多我能找到的关于问候的信息在 linux 上部署 fastapi —— 特别是 ubuntu 18.04.4 —— 使用 apache2 没有其他的东西。当我没有说别的的时候，我的意思是 docker、caddy 或无论如何。

通常的事情必须事先完成，这些是：

创建 api 将使用的数据库
安装虚拟环境
从 requirements.txt
scp 或从 github 克隆 api
将api的生产代码放在/var/www/
你可以使用 gunicorn 作为实际的服务器，而 apache 是一个可以将你连接到它的反向代理（记住 cd 到包含模块 1st 的实际目录也可以使用屏幕）
通过 "a2enmod proxy proxy_ajp proxy_http rewrite deflate headers proxy_balancer proxy_connect proxy_html" 将 apache2 设置为反向代理
实际输入服务器 conf 文件并启用它（示例在底部提供）
总是做好备份

参考： https://www.vioan.eu/blog/2016/10/10/deploy-your-flask-python-app-on-ubuntu-with-apache-gunicorn-and-systemd/

正在运行的示例 apache 配置文件：

<VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    #ServerName www.example.com

    ServerName server-name
    ServerAdmin webmaster@localhost
    ServerAlias server-alias
    
    #DocumentRoot /document/root/

    <Proxy *>
        AuthType none
        AuthBasicAuthoritative Off
        SetEnv proxy-chain-auth On
        Order allow,deny
        Allow from all
    </Proxy>

    ProxyPass / http://127.0.0.1:port/
    ProxyPassReverse / http://127.0.0.1:port/
    #ProxyPass /api http://127.0.0.1:port/api
    #ProxyPassReverse /api http://127.0.0.1:port/api

    <Directory /document/root/>
        Order deny,allow
        Allow from all
    </Directory>

    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
    # error, crit, alert, emerg.
    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn

    ErrorLog ${APACHE_LOG_DIR}/server-error.log
    LogLevel debug
    CustomLog ${APACHE_LOG_DIR}/server-access.log combined

    # For most configuration files from conf-available/, which are
    # enabled or disabled at a global level, it is possible to
    # include a line for only one particular virtual host. For example the
    # following line enables the CGI configuration for this host only
    # after it has been globally disabled with "a2disconf".
    #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

到运行实际api:

gunicorn api:app -w 1 -k uvicorn.workers.UvicornWorker -b "127.0.0.1:port"

编辑：我根本没有在此处放置任何安全机制

Answer 2

WSGI 服务器与 FastAPI 不兼容，FastAPI 仅在 ASGI 服务器中运行，gunicorn 和所有其他 WSGI 服务器只是与 ASGI worker 深度实施 PEP 标准，它们仍然作为 ASGI 与 worker 一起工作。
