git新增遠端倉庫後不能push

Question

自己有一個阿里雲的ECS（CentOS7），需要把專案放到上面去，但不想通過github，想直接在本地git倉庫中添加遠端倉庫，直接push到ECS上。
在ECS中先建立了專案目錄，並且初始化了倉庫：$ git init
在本地倉庫中加入遠端倉庫：

$ git remote add ECSmaster ssh://username@IP/~/path/.git

添加好之後卻不能push，錯誤訊息如下：

$ git push -u ECSmaster master
username@IP's password:

To ssh://username@IP/~/cloudNote/.git

$ git remote show ECSmaster

以上操作參考的是這篇文章：http://www.cnblogs.com/xiaoya901109/archive/2012/08/03/2620664.html

Answer 1

伺服器上初始化倉庫時應該加上--bare參數
git init --bare

Answer 2

遠端伺服器輸入以下：
git config 'receive.denyCurrentBranch' warn

這種錯誤是出於git的一種保護措施 master->master 怕誤操作
