opengauss2.1.0-oe2203sp3数据库容器“[FAILED] Failed to start User Login Management.”报错信息处理
opengauss2.1.0-oe2203sp3数据库容器运行正常，但检查其日志，发现存在“[FAILED] Failed to start User Login Management.”报错信息，本文记录了处理过程。
一、报错信息

二、报错分析
1、登录容器，查看报错原因
[root@localhost ~]# docker exec -it opengauss /bin/bash

[root@4ec583f58a8c /]# systemctl status dbus
Unit dbus.service could not be found.2、报错分析
提示“systemd-logind.service: Failed to schedule restart job: Unit dbus.socket not found.”，这个错误信息表明在尝试重新启动systemd-logind.service时遇到了问题，具体是因为找不到dbus.socket单元。dbus.socket是D-Bus系统的一个组成部分，用于进程间通信。应该是容器部署过程中少装了dbus服务。
三、问题解决
1、安装dbus
