概述

背景：由于服务器更新，需要把部署在A服务器的GitLab仓库迁移到B服务器上面。

实战

GitLab仓库地址从http://192.168.20.149:8090/迁移到http://192.168.0.149:8090/。背景知识：项目信息在.git/config文件有所显示。先查看一下原始.git/config文件：

[core]
	repositoryformatversion = 0
	filemode = false
	bare = false
	logallrefupdates = true
	symlinks = false
	ignorecase = true
[remote "origin"]
	url = http://192.168.20.149:8090/zhsh/file-center.git
	fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
	remote = origin
	merge = refs/heads/master
[branch "dev"]
	remote = origin
	merge = refs/heads/dev

首先将原来的origin重命名一下：
git remote rename origin origin1

再指定需要迁移到的目标地址：
git remote add origin http://192.168.0.149:8090/zhsh/file-center.git

上传到新服务器：
git push origin --all

这一步，需要先在GitLab Web端创建一下Group，否则报错：

libpng warning: iCCP: cHRM chunk does not match sRGB
remote: The project you were looking for could not be found.
fatal: repository 'http://192.168.0.149:8090/zhsh/file-center.git/' not found

git push origin --all重试，成功。去GitLab Web端看一下项目信息：

commit提交记录都有保留，目的达到。

再来看看.git/config文件，已经更新为：

[core]
	repositoryformatversion = 0
	filemode = false
	bare = false
	logallrefupdates = true
	symlinks = false
	ignorecase = true
[remote "origin1"]
	url = http://192.168.20.149:8090/zhsh/file-center.git
	fetch = +refs/heads/*:refs/remotes/origin1/*
[branch "master"]
	remote = origin1
	merge = refs/heads/master
[branch "dev"]
	remote = origin1
	merge = refs/heads/dev
[remote "origin"]
	url = http://192.168.0.149:8090/zhsh/file-center.git
	fetch = +refs/heads/*:refs/remotes/origin/*
