github 提交报403 forbidden的错误解决

创建本地仓库与github的传输

这里假设你的仓库地址为/user/test.git，email地址为youremail@example.com，使用的时候替换成你自己的地址即可。首先注册github帐号，由于你的本地Git仓库和github仓库之间的传输是通过SSH加密的，所以需要使用ssh key：

1）创建SSH Key。在用户主目录下，看看有没有.ssh目录，如果有，再看看这个目录下有没有id_rsa和id_rsa.pub这两个文件，如果有的话，直接跳过此如下命令，如果没有的话，打开命令行，输入如下命令：

# ssh-keygen -t rsa -b 4096 -C "youremail@example.com"

id_rsa是私钥，不能泄露出去，id_rsa.pub是公钥，可以放心地告诉任何人。

2）通过ssh-agent来管理密钥

这里我们通过ssh-agent来管理密钥，ssh-agent是一个密钥管理器，运行ssh-agent以后，使用ssh-add将私钥交给ssh-agent保管，其他程序需要身份验证的时候可以将验证申请交给ssh-agent来完成整个认证过程。

# eval "$(ssh-agent -s)"

# ssh-add –l

4096 7d:8c:84:86:95:ce:47:29:d4:9b:39:8e:28:0c:62:c9 /root/.ssh/id_rsa (RSA)

3）登录github，打开”settings”中的SSH Keys页面，然后点击“Add SSH Key”，填上任意title，在Key文本框里黏贴id_rsa.pub文件的内容。

同步仓库并解决403报错

这时候对本地仓库和github进行同步

# git push -u origin master

error: The requested URL returned error: 403 Forbidden while accessing https://github.com/user/test.git/info/refs

fatal: HTTP request failed

提示403 Forbidden！

可以看到上面红色加粗的文字（The requested URL returned error: 401 Authorization Required），是权限问题导致的，可以修改.git/config文件追加用户名和密码：

1）编辑.git/config文件

2）在[remote “origin”]下找到找到url变量

3）修改url = https://github.com/user/test.git，修改为url = ssh://git@github.com/user/test.git，修改完了保存

4）通过git push origin master进行同步，已经可以成功了
