源码搭建git，并连接github

一、环境

1、下载源码包

https://mirrors.edge.kernel.org/pub/software/scm/git/

2、安装编译环境

#yum install gcc gcc-c++ zlib zlib-devel perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker  curl-devel expat-devel gettext-devel openssl-devel


二 、安装

#tar -xvf git-2.9.5.tar

#cd git-2.9.5/

#./configure  --prefix=/home/Git

#make && make install

# vi /etc/profile

export PATH=$PATH://home/Git/bin

#source   /etc/profile

三、初始化和账户

# git init
Reinitialized existing Git repository in /home/.git/
# git config --global user.name "zjz"
# git config --global user.email "157@qq.com"
# git config --list
user.name=zjz
user.email=157@qq.com
core.repositoryformatversion=0
core.filemode=true
core.bare=false
core.logallrefupdates=true

四、git用ssh连接github

1、生成本地ssh key

#ssh-keygen -t rsa -C 'git@github.com'

2、复制 公钥，在github 中添加ssh key

# cat .ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDJuDgCtLqplUxi/fH6GvWFR4FcbbWvi2wWUVKNsmmsMhd3mvN8NlYVMaNaoNiuOaZw/N0oKtv5j/PxOnhFEgDlQmgAU5oqLWXfulUe/di1xsLSIbcVV9ff5Uy8RbUwFPQuHaW2TVv2M7FpGoLXUSVm+luHFsjj7emNmuv7q2wh97xXiJPMbywCgWh0+YiO8t5MunihIYegfP8QGd4Zl+6qmwxvPDhVIPd4tRU+exGBEL6k47cmIJRQCmG9XW80WQFYHznoimmzGS5YDLjEQO6NX8YA/CzZYGwtMO20B9QP/ORN/XAYLHjzcvyc0RdHIXaVXyVWkMcrd1t+alS2U+c1 git@github.com
3、在github找到账户设置

4、进行认证（但不能远程连接）

# ssh -T git@github.com

5.在本地添加远程仓库用户名

# git config --global user.name 'xiaohong'

6.在本地添加远程仓库邮箱
# git config --global user.email '512050951@163.com'

7.启用默认的颜色设置
# git config --global color.ui true

8.查看配置

# git config --list
user.name=xiaohong
user.email=512050951@163.com
color.ui=true
#  ls .gitconfig
.gitconfig
# cat .gitconfig
[user]
    name = xiaohong
    email = 512050951@163.com
[color]
    ui = true

9.连接远程仓库
# git remote -v
origin    git@github.com:zjz5740-zjz/zhang.git (fetch)
origin    git@github.com:zjz5740-zjz/zhang.git (push)

10.设置远程仓库地址

# git  init （初始化很重要，不然后续出错）
Initialized empty Git repository in /root/.git/
# git remote add origin git@github.com:zjz5740-zjz/zhang.git

11.克隆远程仓库文件

# git clone git@github.com:zjz5740-zjz/zhang.git
Cloning into 'zhang'...
remote: Enumerating objects: 6, done.
remote: Counting objects: 100% (6/6), done.

remote: Total 6 (delta 0), reused 0 (delta 0), pack-reused 0
Receiving objects: 100% (6/6), done.
Checking connectivity... done.
# ls
anaconda-ks.cfg   zhang

12.上传文件

# git init && ls  (初始化)
cdn.txt  kail.txt
# git remote add origin git@github.com:zjz5740-zjz/zhang.git    （如果报错，执行git remote rm origin ）
# git add . （建立当前文件夹下所有的文件，为准备上传的文件）
#  git commit -m 'this is first commit'   （提交上传说明）
[master aec3079] this is first commit
 1 file changed, 1 deletion(-)
 delete mode 160000 zhang
# git push -u origin master   （上传报错）

解决办法：

# git pull --rebase origin master  （错误的主要原因是github中的README.md文件不在本地代码目录中注：pull=fetch+merge）

小结：带着错误，多百度。
