解决方法
systemd对这种情况有很大的支持.我假设你在应用程序前面运行像Nginx这样的Web服务器作为反向代理,使用它们唯一的套接字名称将流量路由到每个Gunicorn实例的右端点.在这里,我将重点介绍systemd配置.
希望能够停止并启动一个独立的gunicorn实例,并且还希望将它们视为可以一起停止或启动的单个服务.
systemd解决方案涉及创建“目标”,该目标将用于将两个实例视为单个服务.然后,将使用单个“模板单元”允许您向“目标”添加多个gunicorns.
首先,/ etc / systemd / systemd / gunicorn.target:
# See ReADME.md for more about this file [Unit] Description=Gunicorn Documentation=https://example.com/path/to/your/docs [Install] WantedBy=multi-user.target
而已.您已经创建了一个目标,当“启用”将在启动时启动.现在/etc/systemd/system/gunicorn@.service,模板文件:
[Unit] Description=gunicorn daemon After=network.target PartOf=gunicorn.target # Since systemd 235 reloading target can pass through ReloadPropagatedFrom=gunicorn.target [Service] User=ubuntu Group=www-data WorkingDirectory=/home/ubuntu/webapps/%i ExecStart=/home/ubuntu/webapps/djangoenv/bin/gunicorn --workers 3 --bind unix:/home/ubuntu/webapps/%i/kb.sock kb.wsgi:application [Install] WantedBy=gunicorn.target
请注意我对您的文件所做的更改:
>每个实例现在是PartOf =目标.
>由于更新的WantedBy =,启用此服务将使其作为目标的依赖项启动
> WorkingDirectory =和套接字路径现在使用变量,因为该文件现在是模板.
要立即启动或停止所有Gunicorn实例,我们可以简单地:
systemctl start gunicorn systemctl stop gunicorn
我们可以使用启用和禁用来动态添加和删除新的Gunicorn实例:
systemctl enable gunicorn@kenyabuzz systemctl disable gunicorn@ugandabuzz
我们也可以自行停止并启动特定服务:
systemctl start gunicorn@kenyabuzz systemctl stop gunicorn@kenyabuzz systemctl restart gunicorn@kenyabuzz
要了解有关所使用的任何系统指令的更多信息,您可以查看man systemd.directives,它将列出记录每个指令的特定手册页.
