Nginx 错误网关代码 502 archivematica

大家好，我是 Linux 新手。我使用 VMware Workstation 在我的虚拟机上安装了 archivematica。我按照以下指南操作，但当我尝试使用其 IP 地址 172.16.0.12:8000 或甚至不使用端口号访问此机器时，我收到错误消息

502 Bad Gatewaynginx/1.18.0 (Ubuntu).

即使我使用curl我也得到同样的错误

https://www.archivematica.org/en/docs/archivematica-1.13/admin-manual/installation-setup/installation/install-ubuntu/#install-pkg-ubuntu 以下是一些日志

以下是 IPtables 的配置行

Chain ufw-user-input (1 references)
target     prot opt source               destination
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:ssh
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:http
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:8000

ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:https

识别和解决该问题的主要步骤是什么？

答案1

据我所知，此错误“连接到上游时失败（111：连接被拒绝）”意味着 nginx 想要传递连接的服务未启动或未响应超时限制。

因此，请检查您链接的教程中列出的服务是否已启动，例如

sudo systemctl status archivematica-mcp-server
sudo systemctl status archivematica-storage-service
sudo systemctl status archivematica-dashboard

如果其中一个未启动（活动），则调查其未启动的原因
