Set up your default identity

• From the terminal, enter ssh-keygen at the command line.
  The command prompts you for a file to save the key in:
  
  $ ssh-keygen //Generating public/private rsa key pair. //Enter file in which to save the key (/Users/emmap1/.ssh/id_rsa):

  1 2 3

  $ ssh-keygen //Generating public/private rsa key pair. //Enter file in which to save the key (/Users/emmap1/.ssh/id_rsa):

  
  Generating public/private rsa key pair.
  Enter file in which to save the key (/Users/emmap1/.ssh/id_rsa):
• Press the Enter or Return key to accept the default location.

• List the contents of ~/.ssh to view the key files.
  
  $ ls ~/.ssh //id_rsa id_rsa.pub

  1 2	$ ls ~/.ssh //id_rsa id_rsa.pub

Add the key to the ssh-agent

• To start the agent, run the following:
  
  $ eval `ssh-agent` //Agent pid 9700

  1 2	$ eval `ssh-agent` //Agent pid 9700

• Enter ssh-add followed by the path to the private key file:
  
  $ ssh-add ~/.ssh/<private_key_file> // ssh-add ~/.ssh/id_rsa

  1 2	$ ssh-add ~/.ssh/<private_key_file> // ssh-add ~/.ssh/id_rsa

 Add the public key to your Bitbucket settings

• In your terminal window, copy the contents of your public key file. If you renamed the key, replace id_rsa.pub with the public key file name.
  
  $ cat ~/.ssh/id_rsa.pub

  1	$ cat ~/.ssh/id_rsa.pub

• Copy Key ไปใส่ใว้ใน Bitbucket ดังรูป
  
  

จากนั้นก็ทำการ Clone มาที่ Server

* ใส่ . ตามหลังเพื่อไม่ให้ เอาโฟลเดอร์ของ Project มาด้วย
