1.安装docker
#查看linux内核
uname -r
#安装软件包
yum install -y yum-utils
#直接参考网上教程
参考：centos7安装Docker详细步骤（无坑版教程）-腾讯云开发者社区-腾讯云 (tencent.com)
2 用docker部署mysql
#拉取镜像
[root@hdp01 ~]# docker pull mysql:5.7.29

3. 安装docker-compose
[root@hdp01 ~]# sudo curl -L https://get.daocloud.io/docker/compose/releases/download/1.29.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed

[root@hdp01 ~]# sudo chmod +x /usr/local/bin/docker-compose
[root@hdp01 ~]# ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
#查看版本信息
[root@hdp01 ~]# docker compose version
Docker Compose version v2.21.0
4. 安装Harbor
步骤一：将harbor-offline离线包放到虚拟机指定目录下并解压
编辑
步骤二：配置harbor.yml文件
编辑
步骤三：安装并启动Harbor
（注意：docker compose version)
[root@hdp01 harbor]# ./install.sh
[Step 0]: checking if docker is installed ...
Note: docker version: 24.0.6
[Step 1]: checking docker-compose is installed ...
Note: docker-compose version: 2.21.0
[Step 2]: loading Harbor images ...
Loaded image: goharbor/notary-signer-photon:v0.6.1-v1.10.0
[Step 3]: preparing environment ...
[Step 4]: preparing harbor configs ...
prepare base dir is set to /opt/tools/habor/harbor
WARNING:root:WARNING: HTTP protocol is insecure. Harbor will deprecate http protocol in the future. Please make sure to upgrade to https

5.配置、使用Harbor
#查看当前镜像
[root@hdp01 harbor]# docker images

nginx latest 605c77e624dd 2 years a
#任务：将nginx：1.18.0上传到Harbor仓库
#修改/etc/docker/daemon.json文件，修改内容如下

"https://fsp2sfpr.mirror.aliyuncs.com/"
],
"insecure-registries":["192.168.33.133"]
}
#登录harbor
[root@hdp01 harbor]# docker login -u admin -p 123456 192.168.33.133

总结：
本节是关于docker安装与配置以及Harbor使用的一些理论知识和操作演示，在docker部署django项目前需要各位了解与亲自实操，下一节我会分享如何使用docker+nginx+uwsgi去部署django 项目，如果你都是一步一步按照我的步骤来，你会学到很多，欢迎各位靓仔，大佬关注加点赞，感谢支持！
