在項目中使用了webscoket進行實時通訊,但是生產環境又使用了django+nginx+uwsgi的部署方式,我們都知道uwsgi並不能處理websocket請求,所以需要asgi服務器來處理websocket請求,官方推薦的asgi服務器是daphne
1.部署daphne
項目配置文件目錄(wsgi.py同級)下創創建文件asgi.py,加入應用:
"""
ASGI entrypoint. Configures Django and then runs the application
defined in the ASGI_APPLICATION setting.
"""
import os
import django
from channels.routing import get_default_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings")
django.setup()
application = get_default_application()
啟動daphne 測試是否正常運行(成功以后退出)
daphne -p 8001 devops.asgi:application
2.安裝supervisor
supervisor是由python實現的一個進程管理工具,可以確保所管理的進程一直運行,當進
程一點中斷supervisord會自動進行重啟。
安裝步驟
yum安裝:
yum install python-setuptools
easy_install supervisor
或者
yum install -y epel-release
yum install -y supervisor
手動安裝:
wget https://pypi.python.org/packages/source/s/supervisor/supervisor-3.1.3.tar.gz
tar zxf supervisor-3.1.3.tar.gz
cd supervisor
python setup.py install
pip安裝:
pip install supervisor
生成配置文件
echo_supervisord_conf > /etc/supervisord.conf
3.使用supervisor管理daphne進程
編輯/etc/supervisord.conf加入配置
[program:daphne]
directory=/opt/app/devops #項目目錄
command=daphne -b 127.0.0.1 -p 8001 --proxy-headers devops.asgi:application #啟動命令
autostart=true
autorestart=true
stdout_logfile=/tmp/websocket.log #日志
redirect_stderr=true
啟動supervisor
supervisord -c /etc/supervisord.conf
啟動或者停止daphne
supervisorctl start daphne
supervisorctl stop daphne
三、代理webscoket
修改nginx配置文件
/#####轉發配置
upstream wsbackend {
server 127.0.0.1:8001;
}
/######location配置
location /ws/deploy {
proxy_pass http://wsbackend;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_redirect off;
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-Host $server_name;
}
