# 推送到多个远程托管服务器

将代码推送到多个远程托管服务器，多重备份保证安全性，比如推送到`github`和`coding`

有两种情况

1. 同时推送代码到多个仓库
2. 指定推送的地址，比如本次操作仅推送到`github`，不推送到`coding`

首先查看当前已追踪的远程仓库地址

    $ git remote -v
    origin	https://git.dev.tencent.com/zjZSTU/TEST.git (fetch)
    origin	https://git.dev.tencent.com/zjZSTU/TEST.git (push)

当前已追踪了`coding`服务器上的仓库，需要加入`github`仓库

*针对多个远程仓库的推送，使用`SSH`传输协议可以提高操作便捷性*

## 同时推送

### 命令行操作

添加`github`仓库地址

    $ git remote set-url --add --push origin https://github.com/zjZSTU/TEST.git
    $ git remote -v
    origin	https://git.dev.tencent.com/zjZSTU/TEST.git (fetch)
    origin	https://github.com/zjZSTU/TEST.git (push)

再重新添加`coding`的仓库地址

    $ git remote set-url --add --push origin https://git.dev.tencent.com/zjZSTU/TEST.git
    $ git remote -v
    origin	https://git.dev.tencent.com/zjZSTU/TEST.git (fetch)
    origin	https://github.com/zjZSTU/TEST.git (push)
    origin	https://git.dev.tencent.com/zjZSTU/TEST.git (push)

这样就可以同时推送到多个远程仓库

    $ git push -u origin master 
    Username for 'https://github.com': zjZSTU
    Password for 'https://zjZSTU@github.com': 
    ...
    ...
    To https://github.com/zjZSTU/TEST.git
    d19a01e..4b76b5d  master -> master
    Branch master set up to track remote branch master from origin.
    Username for 'https://git.dev.tencent.com': zjZSTU
    Password for 'https://zjZSTU@git.dev.tencent.com': 
    ...
    ...
    To https://git.dev.tencent.com/zjZSTU/TEST.git
    d19a01e..4b76b5d  master -> master
    Branch master set up to track remote branch master from origin.

### 文件操作

修改`.git`文件夹下的`CONFIG`文件

    # 原先
    [remote "origin"]
    fetch = +refs/heads/*:refs/remotes/origin/*
    url = https://git.dev.tencent.com/zjZSTU/TEST.git

    # 修改为
    [remote "origin"]
    fetch = +refs/heads/*:refs/remotes/origin/*
    url = https://git.dev.tencent.com/zjZSTU/TEST.git
    pushurl = https://github.com/zjZSTU/TEST.git
    pushurl = https://git.dev.tencent.com/zjZSTU/TEST.git

在`origin`小节中添加属性`pushurl`，设置多个远程仓库地址

## 指定推送

指定推送操作和同时推送操作能够同时并存在同一个仓库中

默认情况下使用`origin`作为远程仓库名，可以添加另外的名字，在旗下指定新的远程仓库

当前操作如下：默认`origin`指向`coding`，添加`github`指向`github`仓库，添加`all`指向`github`和`coding`

### 命令行操作

添加`github`远程

    $ git remote add github https://github.com/zjZSTU/TEST.git
    $ git remote -v
    github	https://github.com/zjZSTU/TEST.git (fetch)
    github	https://github.com/zjZSTU/TEST.git (push)
    origin	https://git.dev.tencent.com/zjZSTU/TEST.git (fetch)
    origin	https://git.dev.tencent.com/zjZSTU/TEST.git (push)

添加`all`远程

    $ git remote add all https://github.com/zjZSTU/TEST.git
    $ git remote set-url --add --push all https://git.dev.tencent.com/zjZSTU/TEST.git
    $ git remote set-url --add --push all https://github.com/zjZSTU/TEST.git
    $ git remote -v
    all	https://github.com/zjZSTU/TEST.git (fetch)
    all	https://git.dev.tencent.com/zjZSTU/TEST.git (push)
    all	https://github.com/zjZSTU/TEST.git (push)
    github	https://github.com/zjZSTU/TEST.git (fetch)
    github	https://github.com/zjZSTU/TEST.git (push)
    origin	https://git.dev.tencent.com/zjZSTU/TEST.git (fetch)
    origin	https://git.dev.tencent.com/zjZSTU/TEST.git (push)

上传代码

    # 上传到coding
    git push -u origin master
    # 上传到github
    git push -u github master
    # 同时上传
    git push -u all master

### 文件操作

修改`.git`文件夹下的`CONFIG`文件，添加`github`和`all`小节

    [remote "github"]
        url = https://github.com/zjZSTU/TEST.git
        fetch = +refs/heads/*:refs/remotes/github/*
    [remote "all"]
        url = https://github.com/zjZSTU/TEST.git
        fetch = +refs/heads/*:refs/remotes/all/*
        pushurl = https://git.dev.tencent.com/zjZSTU/TEST.git
        pushurl = https://github.com/zjZSTU/TEST.git
