今天本地Git Push 代码推送远程分支，提示如下错误信息：

zzg@LAPTOP-8R0KHL88 MINGW64 /e/idea_workspace (master)
    $ git push
    ssh: Could not resolve hostname github.com: No address associated with hostname
    fatal: Could not read from remote repository.
    
    Please make sure you have the correct access rights
    and the repository exists.

Google 一下，大家的建议是重新配置ssh Key。

**重新生成GitHub SSH Key 值，请参考如下指令**

zzg@LAPTOP-8R0KHL88 MINGW64 /e/idea_workspace (master)
    $ git config user.name
    zhouzhiwengang
    
    zzg@LAPTOP-8R0KHL88 MINGW64 /e/idea_workspace (master)
    $ git config user.email
    zhouzhiwengang@163.com
    
    zzg@LAPTOP-8R0KHL88 MINGW64 /e/idea_workspace (master)
    $ ssh-keygen -t rsa -C "zhouzhiwengang@163.com"
    Generating public/private rsa key pair.
    Enter file in which to save the key (/c/Users/zzg/.ssh/id_rsa):
    /c/Users/zzg/.ssh/id_rsa already exists.
    Overwrite (y/n)? y
    Enter passphrase (empty for no passphrase):
    Enter same passphrase again:
    Your identification has been saved in /c/Users/zzg/.ssh/id_rsa
    Your public key has been saved in /c/Users/zzg/.ssh/id_rsa.pub
    The key fingerprint is:
    SHA256:ikXfYyRhWd/897SdPdU+Q/NKTgoZVFm4a4/4qzICidw zhouzhiwengang@163.com
    The key's randomart image is:
    +---[RSA 3072]----+
    |        oo. .+.  |
    |       ... ooo   |
    |      . . o ..o  |
    |     . . =  .  ..|
    | . o .. S =  . o*|
    |  o Eo . . +o .o@|
    |    ...   oo oo**|
    |      . o ...=..+|
    |       . o.o+.o  |
    +----[SHA256]-----+
    
    zzg@LAPTOP-8R0KHL88 MINGW64 /e/idea_workspace (master)
    $ eval $(ssh-agent -s)
    Agent pid 909
    
    zzg@LAPTOP-8R0KHL88 MINGW64 /e/idea_workspace (master)
    $ ssh-add /c/Users/zzg/.ssh/id_rsa
    Identity added: /c/Users/zzg/.ssh/id_rsa (zhouzhiwengang@163.com)
    
    zzg@LAPTOP-8R0KHL88 MINGW64 /e/idea_workspace (master)
    $ clip < /c/Users/zzg/.ssh/id_rsa.pub

执行以上指令完成本机SSH Key值生成，并将生成的Key 拷贝至Git 账户/Setting/SSH key 设置。

温馨提示：SSH Key 生成时，会提示本地已经存在是否覆盖，选择y,再Enter回车。

**重新尝试git 代码推送**

zzg@LAPTOP-8R0KHL88 MINGW64 /e/idea_workspace (master)
    $ ssh -T git@github.com
    ssh: Could not resolve hostname github.com: No address associated with hostname

错误含义：域名解析无法找到GitHub.

Google 一下，大家的解决办法时，将GitHub IP地址配置至hosts文件。

**解决Github 域名方法问题：**

第一步：查询Github 真实IP地址，可以通过[ https://www.ipaddress.com/][https_www.ipaddress.com]查询。

第二步：在本机：C:\\Windows\\System32\\drivers\\etc\\hosts 文件中，添加如下配置：

# Copyright (c) 1993-2009 Microsoft Corp.
    #
    # This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
    #
    # This file contains the mappings of IP addresses to host names. Each
    # entry should be kept on an individual line. The IP address should
    # be placed in the first column followed by the corresponding host name.
    # The IP address and the host name should be separated by at least one
    # space.
    #
    # Additionally, comments (such as these) may be inserted on individual
    # lines or following the machine name denoted by a '#' symbol.
    #
    # For example:
    #
    #      102.54.94.97     rhino.acme.com          # source server
    #       38.25.63.10     x.acme.com              # x client host
    
    # localhost name resolution is handled within DNS itself.
    #	127.0.0.1       localhost
    #	::1             localhost
    140.82.113.4 github.com

**至此，我的Git代码推送恢复正常。**
