Git push提交时报错Permission denied(publickey)...Please make sure you have the correct access rights and the repository exists.

一、git push origin master 时出错

错误信息为：
Permission denied(publickey).

fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

可能：

可能没联网

可能没配置好.git/conf文件

可能是与github上的账号没建立密钥对

二、解决办法

配置文件: 进入你的仓库，下面有个.git目录里面有conf配置文件，直接vim .git/conf
修改成如下:如果不是git提交是https方式，url和pushurl自己改成自己仓库的地址就好

 11
 12 [remote "origin"]
 13     url = git@github.com:s--enten--/--an.git
 14     fetch = +refs/heads/*:refs/remotes/origin/*
 15     pushurl = git@github.com:s--enten--/--an.git.git
 16 [branch "master"]
 17     remote = origin
 18     merge = refs/heads/master

建立密钥：

1. ssh-keygen -t rsa -C "youremail@example.com"

   注意，上述youremail@example.com是指github账户的注册邮箱

2. ssh -v git@github.com

   上述命令执行后，出现的提示最后两句是

   No more authentication methods to try.

   Permission denied (publickey).

3. ssh-agent -s

   上述命令执行后，出现的提示最后两句是

   SSH_AUTH_SOCK=/tmp/ssh-GTpABX1a05qH/agent.404; export SSH_AUTH_SOCK;

   SSH_AGENT_PID=13144; export SSH_AGENT_PID;

   echo Agent pid 13144;

4. ssh-add ~/.ssh/id_rsa

   上述命令执行后，出现提示

   Identity added: . . . (这里是一些ssh key 文件路径)

   Could not open a connection to your authentication agent.

5. 若第4步中出现上述提示，则执行此步骤，否则执行6

   eval 'ssh-agent -s'

   ssh-add ~/.ssh/id_rsa

6. vim ~/.ssh/id_rsa.pub

   上述命令执行后id_rsa.pub文件内容将输出到终端，复制里面的密钥（内容一般是以ssh-rsa 开头，以github账号的注册邮箱结尾的，全部复制下来）

7. 进入github账号，在settings下，选SSH and GPG keys, 点击new SSH key
