Git环境配置

第一步：

生成ssh key，使用命令 “ssh-keygen -t rsa -C “your_email@youremail.com“”，your_email是你的email默认在用户的家目录下.ssh/id_rsa.pub文件里面

第二步：

回到github，进入Account Settings，左边选择SSH Keys，Add SSH Key,title随便填，粘贴key。

第三步：

测试ssh key是否成功，使用命令“ssh -T git@github.com”，如果出现You’ve successfully authenticated, but GitHub does not provide shell access 。这就表示已成功连上github。

如果出现“Agent admitted failure to sign using the key.Permission denied (publickey).”这个错误的话，在命令行下执行”ssh-add”，这样就可以了。

第四步：

配置Git的配置文件，username和email

1 2	git config --global user.name "your name" //配置用户名 git config --global user.email "your email" //配置email

clone至本地以及push到Github

clone

1	git clone https://github.com/chenguolin/scrapy.git

1	git pull origin master

push

1	git add xxx

1	git commit -m

1	git push origin master

代码冲突常见解决方法

如果系统中有一些配置文件在服务器上做了配置修改,然后后续开发又新添加一些配置项的时候,

在发布这个配置文件的时候,会发生代码冲突:

error: Your local changes to the following files would be overwritten by merge:
protected/config/main.php
Please, commit your changes or stash them before you can merge.

如果希望保留生产服务器上所做的改动,仅仅并入新配置项, 处理方法如下:

git stash
git pull
git stash pop
然后可以使用Git diff -w +文件名来确认代码自动合并的情况.

反过来,如果希望用代码库中的文件完全覆盖本地工作版本. 方法如下:

git reset –hard
git pull
其中git reset是针对版本,如果想针对文件回退本地修改,使用

1	git checkout HEAD file/to/restore

英文版pull和push教程

In below section, I am writing step by step how I pushed the code in Github repo successfully
Follow the given below steps from where(Desktop/Server) you want to push the code into Github repo :

Step 1:

Clone the github repo into your system. (You should first create a repo in Github)

Get repo url at right hand sidebar of your repo page. Replace your github repo’s HTTPS url with https://github.com/USER-NAME/REPO-NAME.git

1	git clone https://github.com/USER-NAME/REPO-NAME.git

For EXAMPLE:

1	git clone https://github.com/sharadchhetri/testrepo.git

After cloning will be finished, you will find the directory name matching with the name of Github repo name you just cloned.

Step 2 : （Unnecessary）

Copy your code or files to REPO-NAME directory

For example, I have saved my codes in my desktop at /home/sharad/MyCode directory. Here, I am copying all codes and child directories into REPO-NAME directory .

1	cp -rvf /home/sharad/MyCode/* /home/sharad/testrepo

Step 3 :

Change to git cloned directory i.e REPO-NAME.

1	cd REPO-NAME

Step 4 :

Set Github account username and email id for authentication

1 2	git config --global user.email "your-email-id@example.com" git config --global user.name "Your-Github-UserName"

Step 5:

Set Github URL. (This section is actually solution of this problem)

1	git remote set-url origin https://Your-Github-UserNAme@github.com/Your-Github-UserNAme/REPO-NAME

For EXAMPLE.

1	git remote set-url origin https://sharadchhetri@github.com/sharadchhetri/testrepo.git

Step 6:

Now add all files and directory by using below given command inside REPO-NAME directory
(There is a dot in command, can you see that!)

git add .

Step 7:

Now write comment on commit

1	git commit -m 'my first commit'

Step 8:

Now push the code in Github repo.
Be ready with your github account password because it will ask.

1	git push -u origin master

I hope the solution also work for you.
