欢迎来到【一个大西瓜】的博客

不曾为梦想奋斗,拿什么去燃烧青春。有梦之人亦终将老去,但少年心气如昨。
太阳每一个时刻都同时是夕阳和朝阳,每天她沉入西边,意味着她同时从另一面土地升起。

Github下载提速与Git常用命令

Github下载提速

第一步:打开codeload.github.com.ipaddress.com 找到你浏览器上实际显示的IP地址分别查询github.global.ssl.fastly.net和github.com, 例图 :

 

第二步:按win+r唤起运行框,输入cmd,然后再依次ping一下上面的两个地址

第三步:打开你C:\Windows\System32\drivers\etc\hosts文件,在文件末尾追加如下一行即可,IP地址选第二步测试TTL值小的那个。 192.30.253.121 codeload.github.com


另外分享一下我的github hosts,可能对你所在地区来说不是最优版本,最优hosts的选择可以参考上面三个步骤

# Github
151.101.44.249 http://github.global.ssl.fastly.net

第四步 更新DNS缓存

windows:

// 查看DNS缓存内容
ipconfig /displaydns

// 删除DNS缓存内容
ipconfig /flushdns

linux:

sudo dscacheutil -flushcache

 

Git常用命令

环境的构建

查看版本的命令:

git --version

查看git的安装目录:

which git

常用命令

#使用git命令初始化文件夹,即创建git本地仓库
$ git init
Initialized empty Git repository in /Users/Mac/Desktop/myapp/.git/
#配置全局变量
$ git config --global user.name "***"
$ git config --global user.email '****@qq.com'
#将index.jsp 添加到git仓库中
$ git add index.jsp
#获取git本地仓库状态
$ git status
#使用通配符添加文件到本地仓库,此命令表示将需要添加的本地仓库的所有html文件添加到本地仓库
$ git add *.html
#此命令表示将需要添加的本地仓库的所有文件添加到本地仓库
$ git add .
#从git本地仓库中移除index.jsp文件
$ git rm --cached index.jsp
#将已添加到本地仓库的文件全部提交,当输入此命令时,会切换到一个编辑页面,此时需输入此次提交的备注信息,保存退出即可
$ git commit
#此命令中参数'-m'后添加备注信息
$ git commit -m 'another change'
#创建.gitignore文件,该文件的作用是忽略文件中的指定文件,即不用添加提交的文件
$ touch .gitignore
#演示创建分支的方法,在分支下修改文件,除非合并,否则不会实质性修改主线的内容
$ git branch login
#切换到master角色下
$ git checkout master
#在master角色下合并分支命令
$ git merge login
#以下演示同步到GitHub上
#查看是否已有远程连接
$ git remote
#创建远程连接命令,"***"此内容需要在GitHub指定查看上复制
$ git remote add origin git@github.com:****/***.git
#将本地仓库中的文件推送到GitHub仓库上
$ git push -u origin master
#由于之前已建立连接,故此时只需直接即可push
$ git push
#从GitHub仓库中克隆项目到本地仓库
$ git clone **@github.com:***/homework.git
