1. 安装 openssh-server ,用于建立SSH服务。html
sudo apt-get install openssl-server
使用命令ps -e|grep ssh,查看ssh服务是否启动。linux
若是正常启动,则会显示相似信息:1966 ? 00:00:00 ssh-agent android
2. 建立用户名为git的用户,用来管理和运行git服务。git
sudo user del -r git // 删除已经存在的叫git的用户;
sudo adducer git // 添加用户名叫git的用户;
进入git用户目录下,建立目录.ssh,而后在.ssh目录下建立名为authorized_keys的文件;github
cd /home/git
sudo mkdir .ssh
cd .ssh
touch authorized_keys
将客户端的公钥(生成方法见后文)拷贝到authorized_keys文件中;shell
cat path/id_rsa.pub >> /home/git/.ssh/authorized_keys
安装 git-coreubuntu
sudo apt-get install git-core
3. 初始化服务端仓库vim
git —bare init /home/git/test1.git
注:该命令会生成一个空仓库,此时test1.git对应的地址则为git@hostIp:/home/git/test1.gitbash
或者:服务器
mkdir test1.git
cd test1.git
git —bare init
4. 客户端运行ssh-keygen -t rsa生成密钥;
生成密钥后,在.ssh目录下,会有两个文件id_rsa和id_rsa.pub文件,id_rsa.pub为公钥,经过命令scp /home/git/.ssh/id_rsa.pub gitServer:/home/git将client上生成的公钥拷贝到gitServer上;
服务端把公钥添加到authorized_keys文件中后,客户端就能经过路径访问到git仓库了;
生成密钥时,会要求你确认保存公钥的位置(默认为~/.ssh/id_rsa),而后会让重复一个密码两次,若是不想在使用公钥的时候输入密码,则留空;
假定hostIp为192.168.1.100
git clone git@192.168.1.100:/home/git/test1.git
5. 经常使用git命令
>1. git clone
语法:git clone 版本库网址 本地库名称(可省略)
>2. git remote
此命令用于管理远程主机名,在没有参数的状况下能够列出全部主机名;
git remote
origin
显示origin是在使用clone命令,克隆远程版本库时git自动为远程主机命令;
经过git remote -v 查看版本库的地址;
>3. git fetch
语法:git fetch origin(git fetch origin master)
默认状况下,git fetch origin将会更新远程主机origin上全部分支,若是只想更新某个分支则在主机名后加分支名
>4. git push
语法:git push 远程主机名 本地分支名:远程分支名
若是省略远程分支名,则表示将本地分支推送与存在最终关系的远程分支,若是远程分支不存在,则会被建立;
git push origin master,表示将本地master分支推送到origin主机的master分支;
若是省略本地分支名,则表示要删除远程主机中的分支,如git push origin : master,则表示删除origin主机中的master分支;
>5. git pull
语法:git pull 远程主机 远程分支:本地分支 如:git pull origin master:master,表示将远程主机origin中的master分支更新到本地分支master;
6. 每次添加一个新项目都须要经过shell登入主机并建立一个纯仓库,咱们不妨以gitServer做为git用户和仓库所在的主机名,若是你在网络内部运行该主机,而且在DNS中设定gitServer指向该主机,则如下这些命令都是可用的:
cd myproject git init git add . git commit -m “initial commit” git remote add origin git@gitServer:test1.git git push origin master
建立一个版本库仓库
这样,其它人的克隆和推送也同样
git clone git@gitServer:/test1.git vim README git commit -am ‘fix for the README file’ git push origin master
7. 做为一个额外的防御措施,能够用git自带的git-shell工具来把git用户的活动限制在仅与git相关。把它设为git用户登入的shell,那么该用户就不能拥有主机正常的shell访问权,为了实现这一点,须要指明用户的登入shell为git-shell,而不是 bash 或者 csh,能够经过编辑/etc/passwd文件
sudo vim /etc/passwd
在文件末尾,找到相似此行
git:x:1000:1000::/home/git:/bin/sh
将bin/sh改成/usr/bin/git-shell
git:x:1000:1000::/home/git:/usr/bin/git-shell
如今git用户只能用ssh链接来推送和获取git仓库,而不能直接使用主机shell。
