+# 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
