ssh key 生成步驟
一、設置git的user name和email：
$ git config --global user.name "lei.li"
$ git config --global user.email "lei.li@gmail.com"
二、生成SSH密鑰過程：
1.查看是否已經有了ssh密鑰：cd ~/.ssh
如果沒有密鑰則不會有此文件夾，有則備份刪除
2.生存密鑰：
$ ssh-keygen -t rsa -C “haiyan.xu.vip@gmail.com”
按3個回車，密碼為空。
Your identification has been saved in /home/tekkub/.ssh/id_rsa.
Your public key has been saved in /home/tekkub/.ssh/id_rsa.pub.
The key fingerprint is:
………………
最后得到了兩個文件：id_rsa和id_rsa.pub
3.添加密鑰到ssh：ssh-add 文件名
ssh-agent bash -login -i
ssh-add ~/.ssh/kaka_rsa
將生成公鑰文件放到服務器端(由服務器管理員來放置)
gerrit網站配置
進入設置界面
1.設置用戶名郵箱(用戶名和郵箱要和上面設置git的用戶名和郵箱一致，否則會出現下面錯誤)
2.設置SSH Public Keys
--------------------------------
gpg: Can't check signature: public key not found
error: could not verify the tag 'v1.12.26.ts'
出錯原因是曾使用repo sync從其它庫sync過代碼，刪掉~/.repoconfig即可：
$ rm -rf ~/.repoconfig

原因：配置的git user.email信息與gerrit注冊的郵箱不一致。
解決：
repo forall -c 'git config user.email fenglong.zhong@spreadtrum.com'
repo forall -c 'git config user.name fenglong.zhong'
重新提交你的commit
git reset --soft HEAD~
git commit
執行git push。
