Git 同时与多个远程库互相同步

情形:有两个git服务器，比如github,gitosc,有个项目同时在两个服务器上，要互相同步

其实命令还是比较简单的，比如一个现有的git项目，在github,gitosc中分别创建好对应的项目。

1：移除现在旧有的远程服务器origin

git remote rm origin

2:关联gitosc远程库

git remote add gitosc https://gitee.com/hongdada/learngit.git

git push -u gitosc master

关联github远程库

 git remote add github https://github.com/hongdada/learngit.git

git push -u github master

3.查看远程库信息

λ git remote -v
github  https://github.com/hongdada/learngit.git (fetch)
github  https://github.com/hongdada/learngit.git (push)
gitosc  https://gitee.com/hongdada/learngit.git (fetch)
gitosc  https://gitee.com/hongdada/learngit.git (push)

这样就ok了，就布置好了，下面就是操作

D:代码Gitlearngit
λ git push

   a48d040..875d588  master -> master

D:代码Gitlearngit
λ git push gitosc master
Everything up-to-date

λ git push github master

remote: Resolving deltas: 100% (1/1), completed with 1 local object.

   a48d040..875d588  master -> master

可以看出我第一次是直接git push，没有指定远程库名称，默认推送到了gitosc中，开始还以为一次性推送到了2个服务器呢，剩下的github需要指定名称推送。

如果一次性推送呢

方法一：

D:代码Gitlearngit
λ git remote  rm github

D:代码Gitlearngit
λ git remote rm gitosc

D:代码Gitlearngit
λ git remote add all https://gitee.com/hongdada/learngit.git

D:代码Gitlearngit
λ git remote set-url --add all https://github.com/hongdada/learngit.git

推送：

D:代码Gitlearngit
λ git push all --all

看到有2个推送说明

修改前打开项目.git文件夹内的config文件

[core]
    repositoryformatversion = 0
    filemode = false
    bare = false
    logallrefupdates = true
    symlinks = false
    ignorecase = true
[branch "master"]
    remote = gitosc
    merge = refs/heads/master
[branch "dev"]
[remote "github"]
    url = https://github.com/hongdada/learngit.git
    fetch = +refs/heads/*:refs/remotes/github/*
[remote "gitosc"]
    url = https://gitee.com/hongdada/learngit.git
    fetch = +refs/heads/*:refs/remotes/gitosc/*

 修改后查看：

[core]
    repositoryformatversion = 0
    filemode = false
    bare = false
    logallrefupdates = true
    symlinks = false
    ignorecase = true
[branch "master"]
[branch "dev"]
[remote "all"]
    url = https://gitee.com/hongdada/learngit.git
    fetch = +refs/heads/*:refs/remotes/all/*
    url = https://github.com/hongdada/learngit.git

 方法二：根据上面的配置可以引出第二种一起修改多远程的方式，直接修改配置文件.git/config

删除all

git remote rm all

查看配置文件：

[core]
    repositoryformatversion = 0
    filemode = false
    bare = false
    logallrefupdates = true
    symlinks = false
    ignorecase = true
[branch "master"]
[branch "dev"]

修改配置文件为：

[core]
    repositoryformatversion = 0
    filemode = false
    bare = false
    logallrefupdates = true
    symlinks = false
    ignorecase = true
[branch "master"]
[branch "dev"]
[remote "all"]  
    url = https://github.com/hongdada/learngit.git 
    url = https://gitee.com/hongdada/learngit.git
