linux虚拟机上使用git和github教程

1. GIT是什么？

Git是一个分布式版本控制／软件配置管理软件，原是Linux内核开发者Linus Torvalds为更好地管理Linux内核开发而设计。

相比CVS/SVN，Git 的优势：
－ 支持离线开发，离线Repository
－ 强大的分支功能，适合多个独立开发者协作
－ 速度块

2.GITHUB是什么？

GitHub 是一个共享虚拟主机服务，用于存放使用Git版本控制的软件代码和内容项目。

3.Linux虚拟机上使用git和github

3.1 注册github账号

此步骤比较简单，无需赘述。

3.2 虚拟机安装git客户端

我使用的是CentOS虚拟机，安装命令如下：

yum install git git-gui

[root@CentOS tuzhutuzhu]# ssh-keygen -t rsa -C "*****@**.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
63:68:68:ad:23:0f:8f:85:4a:cc:67:60:47:9e:7a:fa 15895214140@126.com
The key's randomart image is:
+--[ RSA 2048]----+

[root@CentOS tuzhutuzhu]#

3.5 测试是否能连接到GitHub

[root@CentOS tuzhutuzhu]# ssh git@github.com
The authenticity of host 'github.com (192.30.252.131)' can't be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'github.com,192.30.252.131' (RSA) to the list of known hosts.
Enter passphrase for key '/root/.ssh/id_rsa':
Permission denied (publickey).
[root@CentOS tuzhutuzhu]# 

# git config --global user.name "Firstname Lastname"
# git config --global user.email "your_email@youremail.com"
此处用户名为自己的实际姓名(自定义的)，而非登录用户名

创建完成：

3.8 创建本地新项目仓库，此步骤可按照上图GitHub中仓库创建完成后网页上的提示执行

# mkdir new-project(*1)
# cd new-project
# git init
# touch README
# git add README
# git commit -m 'first commit'
定义远程服务器别名origin
#
git remote add origin git@github.com:***/new-project.git(*2)
本地和远程合并，本地默认分支为master
# git push origin master 

在执行push操作时，可能会出现如下错误：

[root@CentOS vmware]# git push -u origin master
error: The requested URL returned error: 403 while accessing https://github.com/tuzhutuzhu/vmware.git/info/refs
fatal: HTTP request failed

1).vim .git/config
2).将[remote "origin"]部分的url按照如下格式设置：
        url = ssh://git@github.com/tuzhutuzhu/vmware.git
        fetch = +refs/heads/*:refs/remotes/origin/*

[root@CentOS vmware]# git push -u origin master

Enter passphrase for key '/root/.ssh/id_rsa':
Counting objects: 7, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (3/3), done.
Writing objects: 100% (7/7), 548 bytes, done.
Total 7 (delta 0), reused 0 (delta 0)
To ssh://git@github.com/tuzhutuzhu/vmware.git
* [new branch]
master -> master
Branch master set up to track remote branch master from origin.
[root@CentOS vmware]# 

这样，就将文件上传到GitHub上了。

还有另外一种解决方法，将url做如下变更：

原：url = https:github.com/tuzhutuzhu/helloworld.git 

现：url = https://tuzhutuzhu@github.com/tuzhutuzhu/helloworld.git 

有关git的详细操作，可以参考如下：
