设置 harbor 开机自动启动：
systemctl enable harbor

查看 harbor 服务状态，运行中：

[root@k8s-master harbor]# systemctl status harbor

使用 docker-compose 先查看 harbor 容器的状态，都是 Up (healthy)，表示正常运行中：

[root@k8s-master harbor]# docker-compose ps -a

6月 05 16:13:32 k8s-master systemd[1]: Stopped Harbor.

使用 docker-compose 查看 harbor 容器的状态，看不到任何容器，连关闭中的容器也没有：

[root@k8s-master harbor]# docker-compose ps -a
Name   Command   State   Ports
------------------------------

再次启动 harbor 服务：
systemctl start harbor

使用 docker-compose 查看 harbor 容器的状态，看到正在启动中的容器：

[root@k8s-master harbor]# docker-compose ps

registryctl         /home/harbor/start.sh            Up (health: starting)

过一会重新查看 harbor 服务状态和 harbor 容器状态，已经全部正常：

通过这种操作可以得出结论，此种方式的本质是删除 harbor 组件的容器，重新创建。跟使用 docker-compose 重启容器的方式完全不同，后者只是重启容器，不是删除重建。

所以本文重启 harbor 的方式，需谨慎使用！！！

通过对比 harbor 重启前后容器的 ID 也能进一步确定这个结论：
重启前的容器 ID：

[root@k8s-master harbor]# docker ps | grep harbor-core
5469180f3cd1   goharbor/harbor-core:v1.10.10                       "/harbor/harbor_core"    8 minutes ago        Up 8 minutes (healthy)                                                 harbor-core

重启后的容器 ID：

[root@k8s-master harbor]# docker ps | grep harbor-core
67cb29a68e1c   goharbor/harbor-core:v1.10.10                       "/harbor/harbor_core"    22 minutes ago   Up 22 minutes (healthy)                                                harbor-core

如果需要 harbor 的容器只是重启，而不是重新创建，在服务脚本 /lib/systemd/system/harbor.service 中就不能使用 docker-compose 的 up 和 down 这两个命令，而是要是改为 start 和 stop 。

如果希望很方便的重启 harbor ，还可以使用另外一种方法，请参考文章：
