## 启用 Gitea Actions 内置的 CI/CD （持续集成、持续交付和持续部署）解决方案

### 配置 Gitea 服务器
```bash
cat << EOF >> gitea/gitea/conf/app.ini
[actions]
ENABLED=true
EOF
docker-compose restart gitea
```

### 生成  Gitea Runner 配置文件
```
mkdir gitea_runner && cd gitea_runner
docker run --entrypoint="" --rm -it gitea/act_runner:latest act_runner generate-config > config.yaml
```

### docker-compose 安装 Gitea Runner 部署
- docker-compose.yml
```yaml
version: "3"

services:
  gitea_runner:
    container_name: gitea_runner
    image: gitea/act_runner:latest
    # 如果使用服务器容器名称作为 URL HOST 的话，需要先启动 Gitea
    depends_on:
      - gitea
    environment:
      CONFIG_FILE: /config.yaml
      # Gitea 服务器地址（也可以是内网地址或者容器内部地址）
      GITEA_INSTANCE_URL: https://gitea.uing.vip
      # 获取地址 https://gitea.uing.vip/admin/actions/runners/
      GITEA_RUNNER_REGISTRATION_TOKEN: ""
      # Runner名称（可选）。如果留空，将使用主机名
      GITEA_RUNNER_NAME: ""
      GITEA_RUNNER_LABELS: ""
    volumes:
      - ./gitea_runner/config.yaml:/config.yaml
      - ./gitea_runner/data:/data
      - /var/run/docker.sock:/var/run/docker.sock
```

## 配置仓库启用 Gitea Actions

1. 打开仓库设置 https://gitea.uing.vip/\<owner\>/\<repo\>/settings
2. 找到并勾选 **启用 Actions** ，并 **更新仓库设置** 保存设置

![enable_actions](/static/img/d32bf0a67ee84027af617b96fac509dc.1693367900388.png)

3. 在仓库代码下新建目录 **.gitea/workflows/**，新建 Yaml 文件编写 Gitea Actions 执行代码
```bash
git clone git@gitea.uing.vip:cainiao/gitea_runner.git

cd gitea_runner && mkdir -p .gitea/workflows/

cat <<"EOF" > .gitea/workflows/demo.yaml
name: Gitea Actions Demo
run-name: ${{ gitea.actor }} is testing out Gitea Actions 🚀
on: [push]

jobs:
  Explore-Gitea-Actions:
    runs-on: ubuntu-latest
    steps:
      - run: echo "🎉 The job was automatically triggered by a ${{ gitea.event_name }} event."
      - run: echo "🐧 This job is now running on a ${{ runner.os }} server hosted by Gitea!"
      - run: echo "🔎 The name of your branch is ${{ gitea.ref }} and your repository is ${{ gitea.repository }}."
      - name: Check out repository code
        uses: actions/checkout@v3
      - run: echo "💡 The ${{ gitea.repository }} repository has been cloned to the runner."
      - run: echo "🖥️ The workflow is now ready to test your code on the runner."
      - name: List files in the repository
        run: |
          ls ${{ gitea.workspace }}
      - run: echo "🍏 This job's status is ${{ job.status }}."
EOF

git add .gitea/workflows/demo.yaml
git commit -m "add .gitea/workflows/demo.yaml"
git push
```
4. 在仓库的 Actions 下查看到执行过程及结果：https://gitea.uing.vip/\<owner\>/\<repo\>/actions

Gitea - 代码项目管理

## 从主仓库更新代码到 fork 仓库
```shell
git remote -v
git remote add github https://github.com/chenxiangfang/Main.git
git fetch github
git merge github/master
git push
```

## 从 github 中拉取变更同步到本地，并提交到 fork 仓库
```shell
git fetch github
git merge github/master
git push
git fetch github --all
git push origin --all
```

## 配置 Git 提交时的邮箱和用户名
```shell
# 全局修改
git config --global user.email "XXX@XXX.com"
git config --global user.name "cainiao"
# 当前仓库修改
git config user.email "XXX@XXX.com"
git config user.name "cainiao"
```

## 设置 HTTP/HTTPS 免密登录（git clone 第二次不需要再次输入密码了）
```bash
# Windows
git config --global credential.helper wincred
# macOS
git config --global credential.helper osxkeychain
```

## 设置 HTTP 代理
```bash
# 设置代理
git config --global http.proxy http://proxyUsername:proxyPassword@proxy.server.com:port
git config --global https.proxy https://proxyUsername:proxyPassword@proxy.server.com:port

# 取消代理
git config --global --unset http.proxy
```

## 线上Git仓库把 **master** 主分支改为了 **main** 主分支
```bash
# Switch to the "master" branch:
git checkout master

# Rename it to "main":
git branch -m master main

# Get the latest commits (and branches!) from the remote:
git fetch

# Remove the existing tracking connection with "origin/master":
git branch --unset-upstream

# Create a new tracking connection with the new "origin/main" branch:
git branch -u origin/main
```

## 我的一些全局 Git 配置
```shell
git config --global http.proxy socks5://127.0.0.1:1080
git config --global https.proxy socks5://127.0.0.1:1080

git config --global user.email "565499699@qq.com"
git config --global user.name "Xiangfang Chen"

git config --global core.autocrlf false
git config --global core.filemode false
git config --global core.preloadindex true
git config --global core.fscache true
git config --global branch.autosetuprebase always
git config --global core.longpaths true
```

> fatal: unsafe repository(XXXX is owned by someone else.)
```shell
# windows:
takeown /r /d y /f <PATH>
# linux:
chown -R username:group <PATH>

# 或者忽略全部文件夹
git config --global --add safe.directory "*"
```

> Filename too long.
```shell
git config --global core.longpaths true
