直接通过aiohttp启动服务

import logging
import asyncio
from aiohttp import web

async def index(request):
    return web.Response(text="Welcome home!")

async def init(loop):
    app = web.Application(loop=loop)
    app.router.add_route('GET', '/', index)
    server = await loop.create_server(app.make_handler(), '0.0.0.0', 9000)
    logging.info('server started at http://127.0.0.1:9000...')
    return server


if __name__ == '__main__':
    event_loop = asyncio.get_event_loop()
    try:
        event_loop.run_until_complete(init(event_loop))
        event_loop.run_forever()
    except KeyboardInterrupt:
        pass
    except BaseException as e:
        logging.error(e)

单独通过gunicorn启动

安装gunicorn：

pip install gunicorn

需要web.Application()

示例: 在app.py文件中:

from aiohttp import web

def index(request):
    return web.Response(text="Welcome home!")


app = web.Application()
app.router.add_route('GET', '/', index)

将程序在localhost的8080端口启动:

gunicorn app:app -k aiohttp.worker.GunicornWebWorker -b localhost:8080

将程序在0.0.0.0的9000端口启动:

gunicorn app:app -k aiohttp.worker.GunicornWebWorker -b 0.0.0.0:9000

通过gunicorn+Nginx部署(推荐)

首先,对Nginx进行配置.

这里以9000端口为例子:

为了和Nginx的主配置分开,我们可以在Nginx的配置文件的http中加入

include /srv/www/server/conf/nginx/*.conf;

在/srv/www/server/conf/nginx/目录下创建新的配置文件:hhuua.com.conf

hhuua.com.conf

server {
    charset utf-8;
    listen 9000;
    server_name www.hhuua.com;

    location / {
        proxy_set_header Host $host;
        proxy_pass http://unix:/tmp/www.hhuua.com.socket;
    }
}

重启Nginx

启动gunicorn

进入到项目目录

aiohttp的代码例子如开头,文件名为:app_main.py

启动:

gunicorn app_main:app --bind unix:/tmp/www.hhuua.com.socket --worker-class aiohttp.GunicornWebWorker

部署完成,进行测试
