先建立SSH Key
利用ssh-keygen產生ssh key，為了方便，我的passphrase是空白，這樣git操作時就不用問密碼了
brook@vista:~$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/brook/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/brook/.ssh/id_ras.
Your public key has been saved in /home/brook/.ssh/id_ras.pub.
The key fingerprint is:
be:5a:86:da:2f:9f:b1:fb:97:f1:bc:bd:30:ba:2a:56 brook@vista
The key's randomart image is:
+--[ RSA 2048]----+

brook@vista:~$ cat /home/brook/.ssh/id_ras.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDcyqsKymOWqwb3OhfYWaFltoKZQnlbJqAEkSf1vPCOxKzZLvCQm+tOxnikTdDDY61qqr+GnitSDbiaBOLELRwg2LAa/MYATK52Di1VI6E9MRVknzdWureV5n10GGQ7zwL3kwXE6pnExwD6gm54hP9LzDM2/tsnLAcP+fvWyu53LCtaRmLC/0kCnAi57gl2d0Hpnp0Zaj/hOyy6DFoVYzBERC7zeem47OZ+NOQ77zd7l+HLujVL2DmS03iZ/e+I89dJIPWFoZbV6d9JlcVXnSkX/jC97HeBYYmELLLZ/vLk6PKNQ1axYgS0/xyodi1XwVTFOYfdk69HGKUOWfQ4B4sj brook@vista
brook@vista:~$
產生出來的Public Key就貼到Setting/SSH Public Keys中，如下圖
Create New Project
接下來就是建立一個新的Project，基本上只要點選Create New Project並填入名稱大致就完成了
接著我將Project的Submit Type設定為FF，因為我不太喜歡有很多merge的log存在
Clone/Push/Pull Project
基本上跟一般git操作沒兩樣，差在gerrit每個commit需要change-id，必須push到refs/for/branch_name等待review，這觀念可以參考下圖
brook@vista:~$ git clone ssh://brook@vista:29418/brook
Cloning into 'brook'...

Review and Submit
基本上Gerrit就是個網頁review system，直接網頁點選就可以完成review/submit等動作
Open頁面顯示待review之commit
點選+2，只有+2才能被submit
點選Submit，code才能真正被merge到project中
Merge頁面顯示被merge的commit
