通过yum源安装:
由于官网的yum源太慢,下面使用阿里云的Yum源进行安装
rm -rf /etc/yum.repos.d/*
#CentOS 7 安装docker依赖三个yum源:Base,Extras,docker-ce
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.aliyun.com/docker-
ce/linux/centos/docker-ce.repo
yum clean all
yum -y install docker-ce
systemctl enable --now docker
删除 docker
[root@centos7 ~]#yum remove docker-ce
#删除docker资源存放的相关文件
[root@centos7 ~]#rm -rf /var/lib/docker
范例: CentOS 7 基于阿里云的安装docker方法
阿里云说明:
https://developer.aliyun.com/mirror/docker-ce?spm=a2c6h.13651102.0.0.3e221b11sUMKNV
# step 1: 安装必要的一些系统工具
yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 添加软件源信息
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-
ce/linux/centos/docker-ce.repo
# Step 3: 更新并安装Docker-CE
yum makecache fast
yum -y install docker-ce
# Step 4: 开启Docker服务
service docker start
# 注意:
# 官方软件源默认启用了最新的软件,您可以通过编辑软件源的方式获取各个版本的软件包。例如官方并没有
将测试版本的软件源置为可用,您可以通过以下方式开启。同理可以开启各种测试版本等。
# vim /etc/yum.repos.d/docker-ee.repo
# 将[docker-ce-test]下方的enabled=0修改为enabled=1
#
# 安装指定版本的Docker-CE:
# Step 1: 查找Docker-CE的版本:
# yum list docker-ce.x86_64 --showduplicates | sort -r
# Loading mirror speeds from cached hostfile
# Loaded plugins: branch, fastestmirror, langpacks
# docker-ce.x86_64 17.03.1.ce-1.el7.centos docker-ce-

范例: 在CentOS 7上安装指定版本的docker
# docker-ce.x86_64 17.03.1.ce-1.el7.centos @docker-ce-
stable
# docker-ce.x86_64 17.03.0.ce-1.el7.centos docker-ce-

# Available Packages
# Step2: 安装指定版本的Docker-CE: (VERSION例如上面的17.03.0.ce.1-1.el7.centos)
yum -y install docker-ce-[VERSION]
#示例
[root@centos7 ~]#yum -y install docker-ce-19.03.12-3.el7
范例: 在CentOS 7上安装指定版本的docker
[root@centos7 ~]#cat /etc/redhat-release
