Hint: Some lines were ellipsized, use -l to show in full.如果显示 Docker 没有运行，可以使用以下命令启动：
bash
sudo systemctl start docker首先，确保 Docker 已经安装并且服务已经启用。你可以使用以下命令来启用 Docker 自启动：
bash
sudo systemctl enable docker输出：
bash
[root@localhost ~]# sudo systemctl enable docker
#表示 Docker 的自启动设置已经成功创建。系统在启动时会自动启动 Docker 服务。
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.你可以重启系统，确保 Docker 服务在系统启动时自动启动：
重启后，你可以使用以下命令确认 Docker 服务是否正在运行：
bash
sudo systemctl status docker此内容由惯性聚合(RSS阅读器)自动聚合整理，仅供阅读参考。 原文来自 — 版权归原作者所有。
