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]----+ | | | | | | | | | S | | o E . | | . * B | | o.= = + =. | | . +=O+o+. .oo| +-----------------+ 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'... The authenticity of host '[1.3.2.8]:29418 ([1.3.2.8]:29418)' can't be established. RSA key fingerprint is cc:29:ae:12:64:ff:e0:19:9b:d1:e4:61:b1:63:4c:51.

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
