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\Git\learngit λ git push Counting 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 -> master D:\代码\Git\learngit λ git push gitosc master Everything up-to-date D:\代码\Git\learngit λ git push github master Counting objects: 2, done.

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\learngit λ git remote rm github D:\代码\Git\learngit λ git remote rm gitosc D:\代码\Git\learngit λ git remote add all https://gitee.com/hongdada/learngit.git D:\代码\Git\learngit λ git remote set-url --add all https://github.com/hongdada/learngit.git
推送：

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
