真的滿麻煩，也不能在shellscript把密碼直接放入，

只好讓兩台server client -> server 免除認證，

步驟1. 至client server(這邊對我來說是jenkins這台server)

//client 建立自己的ssh ras憑證
$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
c3:e9:25:65:00:c8:65:cb:e8:fe:4e:7e:ce:06:a4:9d root@kvm8.deyu.wang
The key's randomart image is:
+--[ RSA 2048]----+
|   . o+..        |
|    o+ . .       |
|    . o   o      |
|   .  .. +       |
|    .+ .S .      |
|   .. E. +       |
|    . ...        |
|     + .o        |
|     .++o        |
+-----------------+

// 將client的pub放到server，該user 家目錄下
$ scp ~/.ssh/id_rsa.pub serverUser@serverIP:~/

步驟2. 切換到 目標Server

// ssh 目標server，這時進去還需要需入密碼
$ ssh serverUser@serverIP

// 把剛剛client傳過來的id_rsa.pub寫入authorized_keys
$ cat ~/id_rsa.pub >> ~/.ssh/authorized_keys

// 離開
$ exit

// 測試ssh連線，如設定成功，就不需要密碼即可以進入
$ ssh serverUser@serverIP

當你將本機端的 Git 加入到遠端的 repository 像是 GitHub …等，若之後你又另外建立新的的 repository 或是要將它搬移至其他遠端數據庫例如 GitLab。此時要刪除原本的 remote origin 該怎麼做？

可參考以下方式

# 專案引入git功能
$ git init

# commit 一些記錄點後
$ git add .
$ git commit -m "[INIT] Add react."
...
$ git commit -m "[INIT] Add react-router."
...
...

# 當測試完成後想要跟遠端專案做link的方式
# ssh
$ git remote add origin ssh://<username>@bitbucket.org/<username>/<project>

# or https
$ git remote add origin https://<username>@bitbucket.org/<username>/<project>

# 移除 remote
$ git remote remove origin

# 觀看目前git remote設定
$ git remote -v

# 設定local分支與遠端分支對齊
$ git branch --set-upstream-to=origin/master master

# 設定push資訊
$ git push -u
$ git push --set-upstream origin master
