github配置密钥SSH keys

当你github创建了一个仓库后，关联本地文件，可能出现以下情况：

• 初始化

$ git commit -m "init page"
[master (root-commit) d832761] init page
 1 file changed, 7 insertions(+)
 create mode 100644 index.html

• 关联本地文件

$ git remote add origin git@github.com:xxxxx/xxxxx.github.io.git

• remote远程

$ git push -u origin master
Permission denied (publickey).
fatal: Could not read from remote repository.

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

• 这是因为本机没有给github配置密匙

• 根据路径找到id_rsa.pub文件，复制里面的内容，粘贴到github的personal settings的SSH keys中
