（gunicorn | uvicorn）+nginx 部署python-sanic項目

 

一、編寫sanic腳本

 

1、創建app

#main.py
from sanic import Sanic
from sanic.response import json as JsonResponse,text,html
from views.user import user_bp
app = Sanic(__name__, strict_slashes = False)
#strict_slashes  對URL最后的 / 符號是否嚴格要求
app.blueprint(user_bp)#注冊藍圖
​
​
#服務啟動運行
@app.listener('before_server_start')
async def setup_db(app, loop):
    pass
#服務器關閉之前
@app.listener('before_server_stop')
async def close_db(app, loop):
    pass
​
​
#異常監聽
@app.exception(ExpiredSignatureError)
async def handleSignatureError(request, exception):
    return json()
​
​
#中間件
@app.middleware('request')
async def middleware:
    pass
​
@app.route("/")
def index(request):
    return JsonResponse({"hello":"world"})
​
if __name__ == '__main__':
    app.run(host = "127.0.0.1", port = 80, debug = True) 

 

2、創建藍圖

#views/user.py
from sanic import Blueprint
from sanic.response import json as JsonResponse
from sanic.views import HTTPMethodView

user_bp = Blueprint('user', url_prefix = "/user")

async def login(request):
    pass

class UserViewsAPI(HTTPMethodView):
    async def get(self, request):
        pass
    async def post(self, request):
        pass
    async def put(self, request):
        pass
    async def delete(self, request):
        pass
user_bp.add_route(login, "/login", methods = ["POST"])
user_bp.add_route(UserViewsAPI.as_view(), "/<obj_id>")

 

二、部署到服務器

1、編寫gunicorn配置文件

#gunicorn_config.py
debug = True
loglevel = 'debug'
bind = '127.0.0.1:8998'   #內部端口
pidfile = 'log/gunicorn.pid'
logfile = 'log/debug.log'
workers = 指定進程數量
worker_class = 'sanic.worker.GunicornWorker'

 

2、使用supervisor運行gunicorn/uvicorn腳本，參考鏈接（https://www.cnblogs.com/mrzhao520/p/14139153.html）

#/etc/supervisord.d/projectname.ini
[program:projectname]
directory=項目的路徑 command=gunicorn -c gunicorn_config.py main:app #啟動gunicorn autostart=true #是否隨supervisor啟動 autorestart=true 　　#是否在意外關閉后重啟 startretires=3 #嘗試啟動次數 user=root #指定用戶執行

[fcgi-program:uvicorn]
socket=tcp://127.0.0.1:8997
command=uvicorn main:app
numprocs=3    #supervisor進程數
autostart=true
autorestart=true
startretries=3
user=root
process_name=%(program_name)s_%(process_num)02d #多個進程需要設置不同的名字
stderr_logfile=logs/error.log
stdout_logfile=logs/out.log

 

3、nginx部署

#/usr/local/nginx/conf/nginx.conf

events {
　　worker_connections 1024;   #nginx的並發數
}
http {
　　include mime.types;
　　default_type application/octet-stream;
　　sendfile on;

　　server {
　　　　listen 80;
　　　　server_name 域名;
　　　　location / {
　　　　　　proxy_pass http://127.0.0.1:8998; #gunicorn啟動的端口
　　　　　　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;
　　　　}
    }

}

 最后運行supervisor和nginx即可。
