概要
使用GitHub时，经常遇到速度慢甚至无法连接的情况（墙），而且GitHub创建私有仓库是需要收费的，有以上需求的可以考虑使用国内的Git托管服务码云。
相比于GitHub，码云有以下优势：
- 首先，在语言的使用上，当然中文交流更畅快、更有效率；
- 其次，国内 IT 行业有自己的特点，天然决定了对开源软件的需求也有自己的特点，比如小程序这个东西，只有国内有，做个开源的小程序托管在码云比 GitHub 明显更有优势，因为关注着都是国内的开发者；
- 然后，开源不仅仅是大项目，像 OpenStack、Tensorflow 这样的大厂大作，确实有 GitHub 就够了，但是这样的大型项目毕竟不是普遍情况。现在编程越来越普及，每个人都可以参与和贡献开源项目，去做一些有意思的东西分享出来，那么从受众、交流便利度、访问速度等方面，码云都有优势
配置公钥
mac下运行
$ ssh-keygen -t rsa -C "XXXXX"
ssh-key
将生成的公钥内容按照如下方式配置到个人码云上
add-sshkey
sshkey
新建项目
newproj
配置远程库关联
首先执行$ git remote -v查看本地关联的远程库，如果没有任何关联，可以执行$ git remote add gitee git@gitee.com:trymesoft/myblog.git添加远程库。
如果存在说明当前目录之前关联过Git远程库，可以在一个新的目录执行$ git init初始化一个新的本地仓库，也可以执行$ git remove rm "XXX"删除， 还可以再添加一个不重名的远程库。
提交的时候指定push，例：$ git push gitee master,这样一来，我们的本地库就可以同时与多个远程库互相同步：
push

有的时候，我们按上述过程配置完成后，执行$ ssh -T v git@gitee.com时，会出现以下错误：
