linux的systemct无法使用

问题描述

在系统运行一段时间后，用ystemctl start docker时报出：Failed to get properties: Failed to activate service ‘org.freedesktop.systemd1’: timed out。

解决思路

1.查看系统日志/var/log/messages
2.更新软件和内核
2.重启服务器

解决步骤

查看系统日志

tail -10 /var/log/messages

标注：
session【会话】 session scope【会话范围】
发现问题和docker无关。尝试使用systeml命令：
systemctl

Failed to list units: Failed to activate service 'org.freedesktop.systemd1': timed out`

所以故障基本可以确认为systemctl服务无法使用，而且是org.freedesktop.systemd1服务的“时间超时”问题。

查看org.freedesktop.systemd1
