Docker 服务启动失败，状态为 203

Question

我有一台带有 Docker EE 的 RHEL 7 服务器，并且在删除 Docker EE 后安装了 Docker CE。但是安装 Docker CE 后，当我尝试使用命令

systemctl enable --now docker

启动 Docker 服务时，它失败并出现以下错误。

Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

当我看到 Docker 服务的状态 (

systemctl status docker.service

) 时，我看到以下错误。

Redirecting to /bin/systemctl status docker.service
  docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)

Docker EE 如何删除？

我通过执行以下步骤删除了 Docker EE。

• 停止 Docker 服务
• yum 删除 docker-ee 和其他 docker 软件包。

安装 Docker 的步骤 - 按照 https://linuxconfig.org/how-to-install-docker-in-rhel-8 中的步骤安装 Docker CE。

我不知道如何解决这个问题。我怎样才能解决这个问题？我应该从哪里开始看？

Answer 1

也许您应该尝试一下以下过程，我在 Oracle Linux 7.9 中测试了它并且它有效。

1. 更新系统包

sudo yum update

2. 安装所需的依赖项

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

3. 设置 Docker CE 存储库

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

4. 安装 Docker CE

sudo yum install docker-ce

5. 启动然后启用Docker服务

sudo systemctl start docker
sudo systemctl enable docker

6. 验证 Docker 安装

sudo docker --version
