git@github.com: Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
在自己的服务器上面开git
git初始化创建目录
cd /home/git //git仓库
mkdir wx.qiaomaimai
cd wx.qiaomaimai
git init --bare
--Initialized empty Git repository in /home/git/wx.qiaomaimai/---表示创建成功
修改用户组权限
chown -R git:git wx.qiaomaimai
后面就是git clone就可以了

楼主下载git闲置了一段时间，某天心血来潮突然想也写一个项目，就打算用git来管理代码。
当楼主在github上建好仓库以后，就准备开始clone，当楼主去找/Users/***/.ssh/id_rsa.pub发现没有（cd ~/.ssh这里可以先简单的检测下，没有就重新生成），
然后就百度了一下，用ssh-keygen -t rsa -C “你的邮箱”这个命令直接生成，之后在/Users/***/.ssh/目录下就生成了两个文件，
到这里的时候，楼主以为就可以搞定了，然后就开始去clone，
直接复制/Users/***/.ssh/id_rsa.pub的内容，然后在github的SSH and GPG keys新建了一个，填上title粘贴上内容，然后回到终端git clone “你的地址”
结果就报了这个
Cloning into 'xxxx'...
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
然后楼主各种百度，发现解决这个问题的办法，就是复制/Users/***/.ssh/id_rsa.pub的内容到github上新建的keys上啊，为什么就不行呢？
。。。
。。。。
。。。。。
各种百度，各种查，真的是一万个草泥马啊。。。。。
于是楼主就决定开始重头再来，把刚才生成的/Users/***/.ssh/*，全部删除掉，
第一步，先验证一下用户名邮箱，git config --global --list，楼主之前就放了一个错误，没有验证就直接复制内容去粘贴了，一般第一次安装都是没有的。
第二步，git config --global user.name "yourname"，git config --global user.email myemail@qq.com 设置全局用户名和邮箱，
第三步，ssh-keygen -t rsa -C "这里换上你的邮箱"，生成秘钥，
接着以为这次总算可以OK了，然后又复制了一遍之前的操作，接着去clone，
！
！
！
！
啃爹啊，结果还是报
Cloning into 'xxxx'...
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
心碎有没有，楼主感觉自己都快奔溃了，到底是为什么呢？
心里一直反复的说要镇定要镇定，然后又是各种百度，最后终于在一位老哥的博客上找到答案了尼玛的太啃爹了
这里提供一下地址https://blog.csdn.net/chaoyueziji123/article/details/54669555
首先测试一下
ssh git@github.com
Warning: Permanently added the RSA host key for IP address '13.250.000.000' to the list of known hosts.
PTY allocation request failed on channel 0
Hi ******! You've successfully authenticated, but GitHub does not provide shell access.
结果是这样的，大概意思就是这个IP地址RSA主机密钥永久的添加到了你的主机列表中，您已经成功地进行了身份验证，但GITHUB不提供shell访问。
解决办法：
1.ssh -v git@github.com
测试ssh连接是否成功，我的现实如下，跟老哥的不太一样，可以连起来看

然后下面两步就关键了，
先使用 ssh-agent -s
SSH_AUTH_SOCK=/var/folders/c6/_lb54v1d4v14_0j4_nt_1vj00000gp/T//ssh-B57Gx7MencHN/agent.32676; export SSH_AUTH_SOCK;
SSH_AGENT_PID=32677; export SSH_AGENT_PID;
echo Agent pid 32677;
再使用 ssh-add ~/.ssh/id_rsa
Identity added: /Users/faye/.ssh/id_rsa (/Users/faye/.ssh/id_rsa)
最后测试 ssh -T git@github.com
Hi nitt! You've successfully authenticated, but GitHub does not provide shell access.
当显示这一句的时候，就万事大吉了，接着就可以愉快的去clone了，
Cloning into '*****'...
remote: Counting objects: 3, done.
remote: Compressing objects: 100% (2/2), done.
remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0
Receiving objects: 100% (3/3), done.
到这里楼主想说，git这个东西还是很值得去研究的，但是楼主比较懒散，一般只会搞明白怎么去使用就好了
所以以楼主的经验就是一步一步搞
第一步，git config --global --list 验证邮箱
第二步，git config --global user.name "yourname"，git config --global user.email myemail@qq.com 设置全局用户名和邮箱，
第三步，ssh-keygen -t rsa -C "这里换上你的邮箱"，生成秘钥，
第四步，到git仓库，添加秘钥，
第五部，ssh -T git@github.com 测试一下通不通，不通就是ssh-agent -s ssh-add ~/.ssh/id_rsa 操作这两步
最后clone，药到病除！！！！
