1. 安装环境

  • 系统版本： Red Hat Enterprise Linux Server release 7.4 (Maipo)

2. 安装步骤

2.1 yum源码

配置系统yum源

  • 镜像yum源，挂在iso镜像，搭建本地yum，/etc/yum.repos.d/local.repo 
[local]
name=local
baseurl=file:///iso
enabled=1
gpgcheck=0
  • docker-ce的阿里yum源码
cd /etc/yum.repos.d/  &&  wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
  • 安装docker-ce
yum clean all 
yum install docker-ce
  • 如果遇到下面报错，说明依赖有问题
正在解决依赖关系
--> 正在检查事务
---> 软件包 docker-ce.x86_64.3.19.03.4-3.el7 将被 安装
--> 正在处理依赖关系 container-selinux >= 2:2.74，它被软件包 3:docker-ce-19.03.4-3.el7.x86_64 需要
--> 正在处理依赖关系 containerd.io >= 1.2.2-3，它被软件包 3:docker-ce-19.03.4-3.el7.x86_64 需要
--> 正在处理依赖关系 docker-ce-cli，它被软件包 3:docker-ce-19.03.4-3.el7.x86_64 需要
--> 正在检查事务
---> 软件包 containerd.io.x86_64.0.1.2.10-3.2.el7 将被 安装
--> 正在处理依赖关系 container-selinux >= 2:2.74，它被软件包 containerd.io-1.2.10-3.2.el7.x86_64 需要
---> 软件包 docker-ce.x86_64.3.19.03.4-3.el7 将被 安装
--> 正在处理依赖关系 container-selinux >= 2:2.74，它被软件包 3:docker-ce-19.03.4-3.el7.x86_64 需要
---> 软件包 docker-ce-cli.x86_64.1.19.03.4-3.el7 将被 安装
--> 解决依赖关系完成
错误：软件包：containerd.io-1.2.10-3.2.el7.x86_64 (docker-ce-edge)
          需要：container-selinux >= 2:2.74
错误：软件包：3:docker-ce-19.03.4-3.el7.x86_64 (docker-ce-edge)
          需要：container-selinux >= 2:2.74
 您可以尝试添加 --skip-broken 选项来解决该问题
 您可以尝试执行：rpm -Va --nofiles --nodigest

将container-selinux安装包下载本地

wget http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.107-3.el7.noarch.rpm
yum localinstall container-selinux-2.107-3.el7.noarch.rpm
  • 安装docker-ce
 yum install docker-ce

2.2 启动docker服务

启动docker系统服务，通过systemctl status docker查看进程状态，正常为active(running)


systemctl start docker
systemctl enable docker
systemctl status docker

2.3 更改docker配置

2.3.1 查看docker信息
[08:13:18-localhost:~/docker]#  docker info

2.3.2 修改镜像存储位置

从docker info中可以看到docker root dir: /var/lib/docker下面

$ cat /etc/docker/daemon.json
{
    "graph": "/docker/images/"
}

$ systemctl restart docker
  • 查看是否改成功
