1,检测系统中git的版本(版本很低)

yum info git

2,git最新源码下载地址

https://github.com/git/git/releases
	https://www.kernel.org/pub/software/scm/git/

3,下载最新的git

wget -P /opt/ https://www.kernel.org/pub/software/scm/git/git-2.14.1.tar.gz

4,解压

tar xzvf git-2.14.1.tar.gz

5,指定安装目录

./configure --prefix=/usr/local/git

6,安装依赖lib

yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
	yum install  gcc perl-ExtUtils-MakeMaker

7,编译安装

make && make install

8,配置环境变量

#git settings
	GIT_HOME=/usr/local/git
	export PATH=$JAVA_HOME/bin:$GIT_HOME/bin:$PATH

9,配置生效

source /etc/profile

10,检查git是否安装成功

git --version

11,创建git账户,密码也为git

useradd git
	passwd git

12,使用git登录并进入git目录

su - git
	 cd ~

13,在/home/git目录下创建.ssh目录,并进入

mkdir .ssh && cd .ssh

14,创建一个存储所有登录用户的公钥(id_rsa.pub),一行一个用户

touch authorized_keys

15,初始化git仓库

mkdir /var/git && cd /var/git
	git init --bare empty.git
	chown -R git:git empty.git

16,禁用shell

vi /etc/passwd
	git:x:1000:1000::/home/git:/usr/bin/git-shell

17,安装windows客户端git,地址https://git-for-windows.github.io/,一路默认安装

https://github.com/git-for-windows/git/releases/download/v2.14.1.windows.1/Git-2.14.1-64-bit.exe

18,打开git bash,直接输出命令生成公钥

ssh-keygen -t rsa -C "lcj@test.com"

19,将C:\Users\Administrator.ssh\id_rsa.pub文件内容写入到git服务器,用来验证

cat id_rsa.lcj.pub >> /home/git/.ssh/authorized_keys

20,使用idea或gitbash从git服务器上clone项目

git clone git@ip:/var/git/emtpy.git

21,设置个人信息

git config [--global] user.email 'lcj@test.com'
	git config [--global] user.name 'lcj'

22,一些问题及其解决方法

加权限
	chown -R git:git .ssh
	
	修改配置,启用ssh公钥认证
	vi /etc/ssh/sshd_config
	RSAAuthentication yes
	PubkeyAuthentication yes
	AuthorizedKeysFile .ssh/authorized_keys
	systemctl restart sshd
