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 -vgithub  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\Git\learngitλ git pushCounting objects: 2, done.Delta compression using up to 4 threads.Compressing objects: 100% (2/2), done.Writing objects: 100% (2/2), 223 bytes | 0 bytes/s, done.Total 2 (delta 1), reused 0 (delta 0)To https://gitee.com/hongdada/learngit.git   a48d040..875d588  master -> masterD:\代码\Git\learngitλ git push gitosc masterEverything up-to-dateD:\代码\Git\learngitλ git push github masterCounting objects: 2, done.Delta compression using up to 4 threads.Compressing objects: 100% (2/2), done.Writing objects: 100% (2/2), 223 bytes | 0 bytes/s, done.Total 2 (delta 1), reused 0 (delta 0)remote: Resolving deltas: 100% (1/1), completed with 1 local object.To https://github.com/hongdada/learngit.git   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\Git\learngitλ git remote  rm githubD:\代码\Git\learngitλ git remote rm gitoscD:\代码\Git\learngitλ git remote add all https://gitee.com/hongdada/learngit.gitD:\代码\Git\learngitλ git remote set-url --add all https://github.com/hongdada/learngit.git

推送：

D:\代码\Git\learngitλ git push all --allCounting objects: 2, done.Delta compression using up to 4 threads.Compressing objects: 100% (2/2), done.Writing objects: 100% (2/2), 269 bytes | 0 bytes/s, done.Total 2 (delta 0), reused 0 (delta 0)To https://gitee.com/hongdada/learngit.git   af6a587..48a0880  master -> masterCounting objects: 2, done.Delta compression using up to 4 threads.Compressing objects: 100% (2/2), done.Writing objects: 100% (2/2), 269 bytes | 0 bytes/s, done.Total 2 (delta 0), reused 0 (delta 0)To https://github.com/hongdada/learngit.git   af6a587..48a0880  master -> master

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
