git倉(cāng)庫(kù)遷移的兩種解決方案

Git倉(cāng)庫(kù)遷移而不丟失log的方法

• 要求能保留原先的commit記錄，應(yīng)該如何遷移呢？
• 同時(shí)，本地已經(jīng)clone了原倉(cāng)庫(kù)，要配置成新的倉(cāng)庫(kù)地址，該如何修改呢？
• 注意：如果使用了代碼審核工具Gerrit，那么在進(jìn)行操作之前需要將Gerrit關(guān)掉，等成功恢復(fù)后再將Gerrit開(kāi)戶即可

1、使用git push --mirror

先了解一些git的基本參數(shù)介紹
git clone --bare

GIT-CLONE(1)                      Git Manual                      GIT-CLONE(1)

NAME
       git-clone - Clone a repository into a new directory

SYNOPSIS
       git clone [--template=<template_directory>]
                 [-l] [-s] [--no-hardlinks] [-q] [-n] [--bare] [--mirror]
                 [-o <name>] [-b <name>] [-u <upload-pack>] [--reference <repository>]
                 [--depth <depth>] [--recursive] [--] <repository> [<directory>]
        --bare
            Make a bare GIT repository. That is, instead of creating <directory> and placing the administrative files
           in <directory>/.git, make the <directory> itself the $GIT_DIR. This obviously implies the -n because there
           is nowhere to check out the working tree. Also the branch heads at the remote are copied directly to
           corresponding local branch heads, without mapping them to refs/remotes/origin/. When this option is used,
           neither remote-tracking branches nor the related configuration variables are created.

git push --mirror

--mirror
           Instead of naming each ref to push, specifies that all refs under refs/ (which includes but is not limited
           to refs/heads/, refs/remotes/, and refs/tags/) be mirrored to the remote repository. Newly created local
           refs will be pushed to the remote end, locally updated refs will be force updated on the remote end, and
           deleted refs will be removed from the remote end. This is the default if the configuration option
           remote.<remote>.mirror is set.

1、建立新倉(cāng)庫(kù)

• 1). 從原地址克隆一份裸版本庫(kù)，比如原本托管于 GitHub，或者是本地的私有倉(cāng)庫(kù)

git clone --bare git://192.168.10.XX/git_repo/project_name.git

• 2). 然后到新的 Git 服務(wù)器上創(chuàng)建一個(gè)新項(xiàng)目，比如 GitCafe，亦或是本地的私有倉(cāng)庫(kù)，如192.168.20.XX

su - git
cd /path/to/path/
mkdir new_project_name.git
git init --bare new_project_name.git

• 3). 以鏡像推送的方式上傳代碼到 GitCafe 服務(wù)器上。
  請(qǐng)確保已經(jīng)添加了公鑰到新的機(jī)器上

cd project_name.git
git push --mirror git@192.168.20.XX/path/to/path/new_project_name.git

• 4). 刪除本地代碼

cd ..
rm -rf project_name.git

• 5). 到新服務(wù)器上找到 Clone 地址，直接Clone到本地就可以了。

git clone git@192.168.20.XX/path/to/path/new_project_name.git

這種方式可以保留原版本庫(kù)中的所有內(nèi)容。

2、切換remote_url

先查看remote的名字

git branch -r

假設(shè)你的remote是origin，用git remote set_url 更換地址

git remote set-url origin remote_git_address

remote_git_address更換成你的新的倉(cāng)庫(kù)地址。

第二種切換remote_url的方法更直接，直接更改.git/conf配置文件里的ip地址就行。

Yesterday is history.
Tomorrow is a mystery.
But today is a gift.
That is why it's called the present.
The old game: give a wolf a taste, then keep him hungry.
