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

--> 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

}
$ systemctl restart docker
