ssh key 生成步骤
一、设置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密钥过程：
1.查看是否已经有了ssh密钥：cd ~/.ssh
如果没有密钥则不会有此文件夹，有则备份删除
2.生存密钥：
$ ssh-keygen -t rsa -C “haiyan.xu.vip@gmail.com”
按3个回车，密码为空。
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:
………………
最后得到了两个文件：id_rsa和id_rsa.pub
3.添加密钥到ssh：ssh-add 文件名
ssh-agent bash -login -i
ssh-add ~/.ssh/kaka_rsa
将生成公钥文件放到服务器端(由服务器管理员来放置)
gerrit网站配置
进入设置界面
1.设置用户名邮箱(用户名和邮箱要和上面设置git的用户名和邮箱一致，否则会出现下面错误)
2.设置SSH Public Keys
--------------------------------
gpg: Can't check signature: public key not found
error: could not verify the tag 'v1.12.26.ts'
出错原因是曾使用repo sync从其它库sync过代码，删掉~/.repoconfig即可：
$ rm -rf ~/.repoconfig

原因：配置的git user.email信息与gerrit注册的邮箱不一致。
解决：
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
执行git push。
