oschina/git github使用指南

我的github仓库开通，https://git.oschina.net/zhjh256。

1、打开https://git.oschina.net/signup，没有账号的话，则新创建账号。

2、从https://github.com/git-for-windows/git/releases/download/v2.9.2.windows.1/Git-2.9.2-64-bit.exe下载并安装。

3、登录git.oschina.net，新建一个项目。

4、打开git bash，如下：

5、生成ssh公钥，如下所示：

$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/zjhua/.ssh/id_rsa):
Created directory '/c/Users/zjhua/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/zjhua/.ssh/id_rsa.
Your public key has been saved in /c/Users/zjhua/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:mOt2ztatHjrGTi8jGaekWo6EXtwy5jOl+12zqZFsVcs zjhua@WINDOWS-DV8B1PN
The key's randomart image is:
+---[RSA 2048]----+
| |
| |
| . |
| o o . |
| o S. E |
| .. ..+.+ |
|. .*++.@.+.. |
|..+B+.Bo@o=.. |
| .o+*o.X*B+. |
+----[SHA256]-----+

6、打开https://git.oschina.net/profile/sshkeys，将id_rsa.pub中的内容拷贝到相应位置，如下：

7、回到git bash，执行下列命令：

$ ssh -T git@git.oschina.net
The authenticity of host 'git.oschina.net (120.55.239.11)' can't be established.
ECDSA key fingerprint is SHA256:FQGC9Kn/eye1W8icdBgrQp+KkGYoFgbVr17bmjey0Wc.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'git.oschina.net,120.55.239.11' (ECDSA) to the list of known hosts.
Welcome to Git@OSC, HS专用!

出现红色代表配置成功。

或$ ssh -T git@githunb.com

8、创建git项目的本地副本。

$ git clone https://git.oschina.net/zhjh256/testgit.git

或 git clone git@github.com:hslightdb/auto_explain.git
Cloning into 'testgit'...
remote: Counting objects: 5, done.
remote: Compressing objects: 100% (3/3), done.
remote: Total 5 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (5/5), done.
Checking connectivity... done.

-------------增加项目或者修改内容---------------

9、提交本地修改

zjhua@WINDOWS-DV8B1PN MINGW64 /d/test/testgit (master)
$ git add *

zjhua@WINDOWS-DV8B1PN MINGW64 /d/test/testgit (master)
$ git status

参考 https://www.cnblogs.com/sober-orange/p/git-token-push.html，获取personel key解决。

$ git push https://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@github.com/hslightdb/citus-benchmarksql.git

10、打开https://git.oschina.net/zhjh256/testgit，看是不是已经提交了。。。

git默认不上传空的文件夹，如果处于项目结构完整性的考虑需要保留目录结构的话，需要在空文件夹中创建一个占位文件比如.gitkeep。

其他：

1、The file will have its original line endings in your working directory。

不影响提交，忽略即可。

2、fatal: empty ident name (for <pms@yhd-jqhadoop39.int.yihaodian.com>) not allowed

解决方法：设置user.email和user.name即可

admin@DESKTOP-LUSBR0A MINGW64 /D/ldpp/trunk/code/io-spider (master)
$ git config --global user.name "zhjh256"

admin@DESKTOP-LUSBR0A MINGW64 /D/ldpp/trunk/code/io-spider (master)
$ git config --global user.email "zhjh256@163.com"

3、删除项目

关于git暂存区，可以参考http://www.cnblogs.com/brothertao/archive/2011/04/01/2002444.html，http://www.cnblogs.com/DreamDrive/p/4155808.html。

检查是否没有内存、空间了？参考https://www.e-learn.cn/content/qita/660565。果然，空间不够了，如下：

zjhua@WINDOWS-MUOVTG8 MINGW64 /e/LightDB-EM-git
$ df -h
Filesystem Size Used Avail Use% Mounted on
D:/Program Files/Git 121G 118G 3.0G 98% /
C: 100G 92G 7.6G 93% /c
E: 121G 121G 7.5M 100% /e
F: 137G 135G 2.0G 99% /f

释放空间后，重新git clone即可。
