# Git多远程仓库同步工作流
|
||||
|
||||
## 仓库配置
|
||||
|
||||
- **upstream**: `http://192.168.189.2:8418/amr.core/web-amr` (镜像仓库，只读)
|
||||
- **origin**: `http://192.168.189.2:8418/xudan/web-map` (你的仓库，可读写)
|
||||
|
||||
## 日常工作流程
|
||||
|
||||
### 1. 从镜像仓库获取最新代码
|
||||
|
||||
```bash
|
||||
# 获取镜像仓库的最新代码
|
||||
git fetch upstream
|
||||
|
||||
# 查看镜像仓库的更新
|
||||
git log HEAD..upstream/master --oneline
|
||||
```
|
||||
|
||||
### 2. 合并镜像仓库的最新代码到本地
|
||||
|
||||
```bash
|
||||
# 方法1: 使用merge (推荐，保留完整历史)
|
||||
git merge upstream/master
|
||||
|
||||
# 方法2: 使用rebase (如果你想要线性历史)
|
||||
git rebase upstream/master
|
||||
```
|
||||
|
||||
### 3. 推送到你的仓库
|
||||
|
||||
```bash
|
||||
# 推送到你的仓库
|
||||
git push origin master
|
||||
```
|
||||
|
||||
## 完整的同步脚本
|
||||
|
||||
### 方法1: 使用merge
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
echo "开始同步镜像仓库..."
|
||||
|
||||
# 获取镜像仓库最新代码
|
||||
git fetch upstream
|
||||
|
||||
# 检查是否有新的提交
|
||||
if git log HEAD..upstream/master --oneline | grep -q .; then
|
||||
echo "发现镜像仓库有新的提交，开始合并..."
|
||||
|
||||
# 合并镜像仓库的代码
|
||||
git merge upstream/master
|
||||
|
||||
# 推送到你的仓库
|
||||
git push origin master
|
||||
|
||||
echo "同步完成！"
|
||||
else
|
||||
echo "镜像仓库没有新的提交，检查本地是否有未推送的修改..."
|
||||
|
||||
# 检查是否有本地修改需要推送
|
||||
if git log origin/master..HEAD --oneline | grep -q .; then
|
||||
echo "发现本地有未推送的修改，推送中..."
|
||||
git push origin master
|
||||
echo "推送完成！"
|
||||
else
|
||||
echo "没有需要同步的内容。"
|
||||
fi
|
||||
fi
|
||||
```
|
||||
|
||||
### 方法2: 使用rebase (如果你想要更干净的历史)
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
echo "开始同步镜像仓库..."
|
||||
|
||||
# 获取镜像仓库最新代码
|
||||
git fetch upstream
|
||||
|
||||
# 检查是否有新的提交
|
||||
if git log HEAD..upstream/master --oneline | grep -q .; then
|
||||
echo "发现镜像仓库有新的提交，开始rebase..."
|
||||
|
||||
# rebase到镜像仓库的最新代码
|
||||
git rebase upstream/master
|
||||
|
||||
# 推送到你的仓库 (可能需要force push)
|
||||
git push origin master --force-with-lease
|
||||
|
||||
echo "同步完成！"
|
||||
else
|
||||
echo "镜像仓库没有新的提交，检查本地是否有未推送的修改..."
|
||||
|
||||
# 检查是否有本地修改需要推送
|
||||
if git log origin/master..HEAD --oneline | grep -q .; then
|
||||
echo "发现本地有未推送的修改，推送中..."
|
||||
git push origin master
|
||||
echo "推送完成！"
|
||||
else
|
||||
echo "没有需要同步的内容。"
|
||||
fi
|
||||
fi
|
||||
```
|
||||
|
||||
## 推荐的工作流程
|
||||
|
||||
1. **每天开始工作前**: 运行同步脚本，确保有最新的镜像仓库代码
|
||||
2. **进行本地开发**: 正常开发你的功能
|
||||
3. **提交本地修改**: `git add` 和 `git commit`
|
||||
4. **推送前再次同步**: 运行同步脚本，确保没有冲突
|
||||
5. **推送到你的仓库**: `git push origin master`
|
||||
|
||||
## 处理冲突
|
||||
|
||||
如果在合并时遇到冲突：
|
||||
|
||||
1. 解决冲突文件
|
||||
2. `git add` 冲突文件
|
||||
3. `git commit` 完成合并
|
||||
4. `git push origin master`
|
||||
|
||||
## 注意事项
|
||||
|
||||
- 使用 `--force-with-lease` 而不是 `--force` 来避免意外覆盖其他人的提交
|
||||
- 定期清理本地分支: `git branch -d <branch-name>`
|
||||
- 如果镜像仓库有大量更新，考虑创建一个新分支来处理合并
