我在尝试打开网站时收到 502 错误。我使用了官方网站 链接中的说明
在/etc/supervisor/conf.d/添加了新文件 lifeline.conf
生命线配置文件
[fcgi-program:asgi]
# TCP socket used by Nginx backend upstream
socket=tcp://localhost:8000
# Directory where your site's project files are located
directory=/home/ubuntu/lifeline/lifeline-backend
# Each process needs to have a separate socket file, so we use process_num
# Make sure to update "mysite.asgi" to match your project name
command=/home/ubuntu/Env/lifeline/bin/daphne -u /run/daphne/daphne%(process_num)d.sock --fd 0 --access-log - --proxy-head$
# Number of processes to startup, roughly the number of CPUs you have

autorestart=true

设置 nginx 配置

我检查了 asgi 日志文件,它包含一个错误。
daphne: error: the following arguments are required: application
我猜在lifeline.conf中有一个错误。
