上篇文章瞭解到瞭如何使用新的版本的harbor，這篇文章來了解一下harbor架構的組成和執行時各個元件的使用方式。

具體說明

proxy

proxy就是使用nginx作為反向代理，而整個的核心則在於nginx的設定檔案，通過如下的設定檔案可以清楚的看到harbor所解釋的將各個其他元件整合在一起的說明內容，而實際的實現也基本上就是靠nginx的設定。

database

可以看到使用的是MariaDB 10.2.14, harbor的資料庫名稱為registry

[[email protected] harbor]# docker exec -it harbor-db sh
sh-4.3# mysql -uroot -pliumiaopw

資料庫表的資訊進行確認後可以看到，當前版本的這種使用方式下，資料庫的表有如下 20張表左右

使用注意事項：自定義埠號

在前一篇文章的例子中我們使用預設的80口作為harbor的埠，如果希望進行更改（比如改為8848），按照如下步驟進行修改即可

設定內容

可以通過檢視資料庫的properties或者api/systeminfo來確認harbor設定專案的詳細資訊
