1. 安装

官方源：

curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor | tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] http://nginx.org/packages/debian bookworm nginx" > /etc/apt/sources.list.d/nginx.list
apt update
apt -y install nginx
nginx -v

2. 反代配置

    default upgrade;
    ''      '';
}

    keepalive_timeout 60s;
}
