准备3台主机，（每台主机，都要安装好docker ,docker-compose）
主机一： 192.168.31.199
主机二： 192.168.31.200
主机三： 192.168.31.201
需要实现主要功能：
主机一安装jenkins拉取git仓库代码，生成docker镜像，在主机二中运行部署站点
主机三用来安装harbor仓库，保存docker镜像
主机一安装jenkins
docker run -u root -d -p 8080:8080 -p 50000:50000 -v ./jenkins-data:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock -v /usr/bin/docker:/usr/bin/docker --restart=always --name=jenkins jenkins/jenkins:lts主机三安装harbor
下载Harbor的压缩包（本课程版本为：v1.9.2）https://github.com/goharbor/harbor/releases上传压缩包到linux，并解压tar -xzf harbor-offline-installer-v1.9.2.tgz mkdir /opt/harbor mv harbor/* /opt/harbor cd /opt/harbor修改Harbor的配置vi harbor.yml修改hostname和porthostname: 192.168.66.102 port: 85安装Harbor./prepare ./install.sh启动Harbordocker-compose up -d 启动 docker-compose stop 停止 docker-compose restart 重新启动访问Harborhttp://192.168.31.201:85默认账户密码：admin/Harbor12345
