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

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。
