今天是Git系列課程第二課,上一課我們已經學會在本地建立一個空倉庫,痞子衡今天要講的是如何將本地倉庫與遠端建立聯絡。
1.將本地倉庫掛上遠端git remote
本地建好了倉庫,我們希望能夠掛到遠端伺服器上,方便與其他人共享。目前最流行的遠端Git伺服器當然是github,此時你需要在github上註冊賬戶並線上建立一個倉庫,此處我們輸入倉庫名為gittest
點選"Create repository"之後便彈出如下畫面,最重要的是我們可以得到一個遠端倉庫的地址:git@github.com:JayHeng/gittest.git。
有了遠端倉庫地址,我們便可以開始將本地倉庫與遠端倉庫建立聯絡:
// 與遠端建立連線之前需要保證本地倉庫為非空,即至少需要一次本地提交
jay@pc MINGW64 /d/my_project/gittest (master)
$ echo "# gittest" >> README.mdjay@pc MINGW64 /d/my_project/gittest (master)
$ git add README.mdwarning: LF will be replaced by CRLF in README.md. The file will have its original line endings in your working directory.
jay@pc MINGW64 /d/my_project/gittest (master)
$ git commit -m "first commit"[master (root-commit) 5fe04f8] first commit 1 file changed, 1 insertion(+) create mode 100644 README.md
// 本地有了提交之後,開始與遠端的地址建立聯絡
jay@pc MINGW64 /d/my_project/gittest (master)
$ git remote add origin git@github.com:JayHeng/gittest.git// 確認本地與遠端的聯絡
jay@pc MINGW64 /d/my_project/gittest (master)
$ git push -u origin masterThe authenticity of host 'github.com (xxx.xx.xxx.xxx)' can't be established. RSA key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'github.com,xxx.xx.xxx.xxx' (RSA) to the list of known hosts. git@github.com: Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
很不幸,我們似乎沒有與遠端建立正確的聯絡,提示“Permission denied”,這是因為github賬號沒有設定ssh公鑰資訊所致,需要前往github網站的"account settings",依次點選"Setting -> SSH and GPG Keys"->"New SSH key",將本地的rsa key(id_rsa.pub裡的字串)填寫進去,下面是生成本地rsa key的方法:
// 建立本地rsa key(如果沒有的話,一直enter/yes;此處痞子衡已經生成過,故直接用之前的key)
jay@pc MINGW64 /d/my_project/gittest (master)
$ ssh-keygen -t rsaGenerating public/private rsa key pair. Enter file in which to save the key (/c/Users/jay/.ssh/id_rsa): /c/Users/jay/.ssh/id_rsa already exists. Overwrite (y/n)? n
在github網站設定好正確rsa key之後便可以再次嘗試與將本地與遠端進行連線:
// 再試一次確認本地與遠端的聯絡
jay@pc MINGW64 /d/my_project/gittest (master)
$ git push -u origin masterWarning: Permanently added the RSA host key for IP address 'xxx.xx.xxx.xxx' to the list of known hosts. Counting objects: 3, done. Writing objects: 100% (3/3), 213 bytes | 213.00 KiB/s, done. Total 3 (delta 0), reused 0 (delta 0) To github.com:JayHeng/gittest.git * [new branch] master -> master Branch 'master' set up to track remote branch 'master' from 'origin'.
好了,大功告成,此時我們已經成功將本地與遠端建立了聯絡,本地分支叫master,對應的遠端分支是origin。
2.克隆遠端倉庫到本地git clone
Git是可以遠端協作的,這意味著任何人建立的共享遠端倉庫都可以被複制到任何機器上,只需要知道遠端倉庫地址即可。
// 將遠端repo克隆到本地
jay@pc MINGW64 /d/my_project
$ git clone git@github.com:JayHeng/gittest.gitCloning into 'gittest'... remote: Counting objects: 3, done. remote: Total 3 (delta 0), reused 3 (delta 0), pack-reused 0 Receiving objects: 100% (3/3), done.
有了遠端共享,再也不用擔心本地倉庫丟失了,想clone就clone,so easy!
