Docker安装步骤
1.配置好虚拟机(CentOS7及以上)且接外网
[root@echohye ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
2.卸载旧版本
(若之前没装过,此步省略)
/
表示连接符而已
yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine
3. 下载安装gcc相关库
yum install -y gcc
yum install -y gcc-c++
4.安装需要的软件包
yum install -y yum-utils
5.设置stable镜像仓库
# 官方的(不推荐,国内网速不友好)
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
# 阿里云yyds
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
6.更新yum软件包索引(可选)
yum makecache fast
7.安装Docker Engine
yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin
8.启动docker
systemctl start docker
[root@echohye ~]# ps -df | grep docker
root 5768 5203 0 23:20 pts/1 00:00:00 grep --color=auto docker
[root@echohye ~]# ps -ef | grep docker
root 5649 1 1 23:20 ? 00:00:00 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
root 5770 5203 0 23:20 pts/1 00:00:00 grep --color=auto docker
9.测试

11.阿里云镜像加速
注:当然不一定要用阿里云的镜像,也可以用国内其它的镜像
注册阿里云账号——>控制台——>菜单——>容器镜像服务
个人学习,就选了个人实例
创建之后,点击镜像工具——>镜像加速器
