# **Git 數據庫** ###### tags: `Git` `Github` * [Git 數據庫](https://w3c.hexschool.com/category/repo) ## **Git 流程圖** ![](https://i.imgur.com/8fbdpqz.png) ## **Github - 遠端數據庫** ### [Github](https://github.com/) ## **git remote add - 添加遠端數據庫** ### 1. Github創建數據庫(Repository) ![](https://i.imgur.com/cVZgBzn.png) #### Repository URL ![](https://i.imgur.com/nNvYsRR.png) ### 2. 本地新增遠端數據庫 #### Git Bash開啟資料夾，輸入指令 > #### git remote add <repository name> <repository url> :::info ``` git $ git remote add origin https://github.com/yehtony/Git_practice.git ``` *git remote add* 表示在本地添加遠端數據庫 。 ::: :::success ``` git $ git remote origin ``` 輸入 *git remote* 可以看到遠端數據庫名稱，代表添加成功。 ::: ## **git push - 更新遠端數據庫** ### 當本地資料新於遠端資料，推送本地資料來使資料同步 > #### git push <repository name> <branch name> :::info ``` git $ git push -u origin master Enumerating objects: 10, done. Counting objects: 100% (10/10), done. Delta compression using up to 12 threads Compressing objects: 100% (7/7), done. Writing objects: 100% (10/10), 905 bytes | 905.00 KiB/s, done. Total 10 (delta 1), reused 0 (delta 0), pack-reused 0 remote: Resolving deltas: 100% (1/1), done. To https://github.com/yehtony/Git_practice.git * [new branch] master -> master branch 'master' set up to track 'origin/master'. ``` *git push* 表示將本地資料推送到遠端數據庫。 *branch 'master' set up to track 'origin/master'* 表示成功將資料推送到遠端數據庫分支。 ::: ## **git pull - 抓取遠端數據庫(合併資料)** ### 當遠端資料異於本地資料，抓取遠端資料來使資料同步 > #### git pull :::info ``` git $ git pull remote: Enumerating objects: 9, done. remote: Counting objects: 100% (9/9), done. remote: Compressing objects: 100% (6/6), done. Unpacking objects: 100% (6/6), 1.35 KiB | 137.00 KiB/s, done. remote: Total 6 (delta 1), reused 0 (delta 0), pack-reused 0 From https://github.com/yehtony/Git_practice 97edecf..312c2b4 master -> origin/master Updating 97edecf..312c2b4 Fast-forward all.css | 5 +++-- index.html | 4 ++-- 2 files changed, 5 insertions(+), 4 deletions(-) ``` *git pull* 表示將遠端資料抓取至本地數據庫，可以看到 *Updating* 表示成功更新(分支同步)。 ::: :::success ``` git $ git log commit 312c2b4eb6ef6cdf2158044eb962e41794cd605c (HEAD -> master, origin/master) Author: YehTony <66704016+yehtony@users.noreply.github.com> Date: Tue Jun 14 18:54:39 2022 +0800 Update index.html commit 39ed4020684ed4cb909810b71effb84dc69fb735 Author: YehTony <66704016+yehtony@users.noreply.github.com> Date: Tue Jun 14 18:54:19 2022 +0800 Update all.css ``` *git log* 可以看到新的 *commit* ，是從遠端抓下來的資料。 ::: ![](https://i.imgur.com/mT8gE2a.png) **抓取遠端資料到遠端分支(origin/master)，並且本地分支(master)自動合併遠端分支，同步資料。** ## **git fetch - 抓取遠端數據庫(不合併資料)** > #### git fetch :::info ``` git $ git fetch remote: Enumerating objects: 7, done. remote: Counting objects: 100% (7/7), done. remote: Compressing objects: 100% (4/4), done. remote: Total 4 (delta 1), reused 0 (delta 0), pack-reused 0 Unpacking objects: 100% (4/4), 756 bytes | 151.00 KiB/s, done. From https://github.com/yehtony/Git_practice 97edecf..b6ed94c master -> origin/master ``` *git fetch* 表示將遠端資料抓取至本地數據庫，但是資料僅更新至遠端分支。 ::: :::success ``` git $ git log commit b6ed94c5ddd8851f9aee01bb4b81094e2e377ab0 (HEAD, origin/master) Author: YehTony <66704016+yehtony@users.noreply.github.com> Date: Fri Jun 17 23:39:03 2022 +0800 更改css ``` *git log* 可以看到新的*commit* HEAD只指向遠端分支。 ::: ![](https://i.imgur.com/4R0KIN1.png) **可以看到遠端資料只抓取到遠端分支(origin/master)，本地分支與遠端分支出現分岐。** ## **git clone - 複製遠端數據庫** #### Repository URL ![](https://i.imgur.com/4X86SRU.png) #### 新建一個資料夾並以Git Bash開啟 > #### git clone <repository url> :::info ``` git $ git clone https://github.com/yehtony/Git_practice.git Cloning into 'Git_practice'... remote: Enumerating objects: 16, done. remote: Counting objects: 100% (16/16), done. remote: Compressing objects: 100% (12/12), done. remote: Total 16 (delta 2), reused 9 (delta 1), pack-reused 0 Receiving objects: 100% (16/16), done. Resolving deltas: 100% (2/2), done. ``` *clone* 遠端數據庫到指定資料夾。 ``` git $ ls Git_practice/ ``` ``` git $ git remote origin ``` *ls* 可以看到資料夾新增了一個遠端複製下來的數據庫，它擁有一樣的版控， 且用 *git remote* 可以發現本地自動新增了該遠端數據庫。 :::
