下载离线安装包
[root@sdw3 ~]# wget https://storage.googleapis.com/harbor-releases/release-1.9.0/harbor-offline-installer-v1.9.1.tgz
[root@sdw3 ~]# tar -xvf harbor-offline-installer-v1.9.1.tgz ; cd harbor   
[root@sdw3 harbor]# ./prepare 
[root@sdw3 harbor]# vi harbor.yml 
hostname: 192.168.106.237
docker-compose需要1.18以上的版本
curl -L https://github.com/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/docker/docker-compose
[root@sdw3 harbor]# ./install.sh 
剩下使用docker-compose控制
docker-compose start


docker-compose stop
