github远程仓库常用命令实战

• 创建ssh key
  ssh-keygen -t rsa -C "email@example.com"

• 生成ssh的秘钥

Administrator@USER-QKAROI6I4J MINGW64 /c/opt/demo2 (master)
$ ssh-keygen -t rsa -C "test@163.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Administrator/.ssh/id_rsa):
Created directory '/c/Users/Administrator/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Passphrases do not match.  Try again.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Administrator/.ssh/id_rsa.
Your public key has been saved in /c/Users/Administrator/.ssh/id_rsa.pub.
The key fingerprint is:test@163.com
The key's randomart image is:

• 切换到密钥目录

Administrator@USER-QKAROI6I4J MINGW64 /c/opt/demo2 (master)
$ cd /c/Users/Administrator/.ssh

Administrator@USER-QKAROI6I4J MINGW64 ~/.ssh
$ ls

• 查看密钥文件

Administrator@USER-QKAROI6I4J MINGW64 ~/.ssh
$ cat id_rsa.pub

• 测试是否连接到github

Administrator@USER-QKAROI6I4J MINGW64 ~/.ssh
$ ssh -T git@github.com
The authenticity of host 'github.com (13.250.177.223)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'github.com,13.250.177.223' (RSA) to the list of known hosts.
Enter passphrase for key '/c/Users/Administrator/.ssh/id_rsa':

access.
 

• 添加远程仓库
  切换到本地仓库，输入以下命令将该仓库关联到github上

Administrator@USER-QKAROI6I4J MINGW64 /c/opt/repodemo2 (master)
$ git remote add origin  git@github.com:test/repodemo2.git

• 将本地仓库推送到github上

Administrator@USER-QKAROI6I4J MINGW64 /c/opt/repodemo2 (master)
$ git push -u origin master
Warning: Permanently added the RSA host key for IP address '113.229.188.59' to the list of 

known hosts.

• 提交到github中

$ git push
warning: push.default is unset; its implicit value has changed in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the traditional behavior, use:

  git config --global push.default matching

To squelch this message and adopt the new behavior now, use:

  git config --global push.default simple

When push.default is set to 'matching', git will push local branches
to the remote branches that already exist with the same name.

Since Git 2.0, Git defaults to the more conservative 'simple'
behavior, which only pushes the current branch to the corresponding
remote branch that 'git pull' uses to update the current branch.

See 'git help config' and search for 'push.default' for further information.
(the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
'current' instead of 'simple' if you sometimes use older versions of Git)
