# Git项目管理

## 1. Git使用用户配置

```bash
git config --global user.name "wang"
git config --global user.email "wangyuedong94@qq.com"

# 查看git配置信息
git config --list
```

## 2. Git基本命令

```bash
# 初始化本地仓库
git init

# 查看仓库git状态
git status

# 增加文件到缓存区
git add <file>

# 提交到本地仓库
git commit -m "Add file"

# 查看本地仓库提交历史记录
git log
git reflog

# 查看提交记录图
git log --decorate --all --graph --oneline

# 回退到之前版本
git reset --hard cef96r(版本编号)
```

## 3. 创建和切换分支

```bash
# 创建分支v0.1
git branch v0.1

# 切换到分支v0.1
git checkout v0.1

# 合并分支，在主分支操作，合并前解决所有同名文件冲突
git merge v0.1

# 删除分支
git branch -d v0.1

# 删除远程分支
git branch -dr remote/branch
git push origin --delete v0.1

# 查看分支
git branch
# 查看所有分支
git branch -a
# 查看远程分支
git branch -r
```

## 4. 远程仓库

```bash
# 添加远程仓库, 可以存在多个远程仓库github, gitlab, gitee
git remote add origin https://gitlab.com/(username)/(project).git
#origin为远程仓库别名

# 推送远程仓库
git push origin master
#git push [远程仓库名] [本地分支名]
#git push [远程仓库名] [本地分支名]:[远程分支名]
#git push origin master:test

# 推送远程仓库加-u
git push -u origin master
# -u设置了默认上传流远程仓库
git push

# 拉取远程仓库项目
git clone <远程仓库地址>

# 拉取远程项目分支v0.1
git clone -b v0.1 <远程仓库地址>

# 拉取远程分支
git fetch origin v0.1

# 拉取远程仓库更新
git pull origin master

# 查看所有远程仓库
git remote

# 设置新的远程仓库地址
git remote set-url origin https://gitlab.com/...

# 删除远程仓库
git remote rm origin 
```

## 5.凭证助手

清除凭证助手

```bash
git config --system --unset credential.helper
# 除了system外，还有global、local等范围
# 使用 git config --list 命令这是展示配置属性，只要不存在credential.helper表示清除成功
```

加认证测试

```bash
ssh -T git@gitee.com
```

或者

```bash
git config --global credential.helper store
# 清除成功后，每次远程操作pull/push/fetch时需要手动输入密码啊。
# 执行这个命令，开启凭证助手，一次输入密码认证成功后会被存储下来。
```
