红帽RHEL安装docker容器引擎

目前红帽RHEL系统下面安装docker可以有两种方式:一种是使用curl获得docker的安装脚本进行安装,还有一种是使用yum包管理器来安装docker。

一、使用安装脚本安装。

备注:你可以按照同样的步骤在CentOS系统下面安装docker。


  1. 使用一个有sudo权限的帐号登录红帽系统。

  2. 更新现有的yum包。

    $ sudo yum 
                    update 
  3. 执行docker安装脚本。

    $ curl -sSL http
                s://
                get.docker.
                com/ | 
                sh 
  4. 启动docker服务。

            $ sudo service docker start
  5. 确认docker安装成功。

    $ sudo docker run hello-world
    Unable 
        to find image 
        'hello-world:latest' locally
    latest: Pulling 
        from hello-world
    a8219747be10: Pull complete 
        91c95931e552: Already exists 
    hello-world:latest: The image you are pulling has been verified. Important: image verification is 
        a tech preview feature 
        and should 
        not be relied 
        
        on 
        to 
        provide 
        security. Digest: sha256:aa03e5d0d5553b4c3473e89c8619cf79df368babd1
        .7
        .1cf5daeb82aab55838d
    Status: Downloaded newer image 
        for hello-world:latest
    Hello 
        from Docker.
    This message shows that your installation appears 
        to be working correctly.
    To generate this message, Docker took 
        the following steps: 
        1. The Docker client contacted 
        the Docker daemon. 
        2. The Docker daemon pulled 
        the 
        "hello-world" image 
        from 
        the Docker Hub.
            (Assuming 
        it was 
        not already locally available.) 
        3. The Docker daemon created 
        a 
        new container 
        from that image which runs 
        the executable that produces 
        the output you are currently reading. 
        4. The Docker daemon streamed that output 
        to 
        the Docker client, which sent 
        it 
        to your terminal.
    To 
        try something more ambitious, you can run 
        an Ubuntu container 
        with:
     $ docker run -
        it ubuntu bash
    For more examples 
        and ideas, visit: 
        http://docs.docker.com/userguide/

二、使用yum包安装

  1. 使用有sudo权限的帐号登录系统。

  2. 更新yum包。

    $ sudo yum 
    update 
  3. 添加docker源。

    $ cat >/etc/yum
    .repos.d/docker
    .repo <<-EOF
    [dockerrepo]
    name=Docker Repository
    baseurl=https:
    //yum.dockerproject.org/repo/main/centos/7 enabled=
    1 gpgcheck=
    1 gpgkey=https:
    //yum.dockerproject.org/gpg EOF
  4. 使用yum命令安装docker。

    $ sudo yum 
    install docker-
    engine 
  5. 启动docker服务。

    $ sudo service docker start
  6. 确认docker是否安装成功。

    $ sudo docker 
    run hello-world

Cannot connect to the Docker daemon. Is 'docker -d' running on this host?
试试 sudo systemctl start docker

用第一种方法使用安装脚本安装的docker 安装完之后为什么没有 /etc/sysconfig/docker文件啊?

服务器启动之后执行:
sudo docker run hello-world
报错了
