1、配置环境变量

• 配置git全局用户名

git config --global user.name "qujunorz"
git config --global user.email "qujunorz@gmail.com"#gerrit中注册的用户名与邮箱

• 修改.git/config

[remote "gerrit"]url = ssh://qujunorz@$代码url地址fetch = +refs/heads/*:refs/remotes/gerrit/*

• 创建.git/hooks中的commit-msg文件
  #为了避免错误“remote: ERROR: missing Change-Id in commit message footer”

• 修改ssh_config

KexAlgorithms +diffie-hellman-group1-sha1

• 上传ssh公钥至服务器

2、代码上传操作

• 克隆代码到本地

git clone $代码在gerrit中地址

• 新建一个分支

git branch -a
#列出本地或远程的所有分支
git branch -r
#列出远程分支
git branch [branch_name]
## 新建分支

• 切换到分支

git checkout  [branch_name]
或者不使用git branch新建，直接git checkout -b实现新建与切换
git checkout -b [branch_name]

• 修改文件并提交

touch aecho “revise” >a
git add a
#添加新文件，如果只是修改或者删除则不需要
git addgit commit -a
#将修改内容提交到仓库中
git commit --amend
#对于已经提交过的代码，如果需要修改，可以借助 git commit --amend 来进行。

• 查看状态并向master提×××并请求

git status
#查看是否已经
commitgit  log
#查看提交日志
git-review master

3、报错

sign_and_send_pubkey: signing failed: agent refused operation
Permission denied (publickey).
fatal: Could not read from remote repository.Please make sure you have the correct access rightsand the repository exists.

• 使用ssh-add命令添加私钥
