• Linux Ubuntu搭建git服务器


    1. 安装 openssh-server ,用于创建SSH服务。

    sudo apt-get install openssl-server

    使用命令ps -e|grep ssh,查看ssh服务是否启动。

    如果正常启动,则会显示类似信息:1966 ?    00:00:00 ssh-agent 

    2. 创建用户名为git的用户,用来管理和运行git服务。

    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,创建目录.ssh,然后在.ssh目录下创建名为authorized_keys的文件;

    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;

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

    安装 git-core

    sudo apt-get install git-core

    3. 初始化服务端仓库

    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.git

    或者:

    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,通过命令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,客户端就能通过路径访问到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),然后会让重复一个密码两次,如果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. 常用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,在没有参数的情况下可以列出所有主机名;

      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;

      通过git remote -v 查看版本库的地址;

    >3. git fetch

      语法:git fetch origin(git fetch origin master)

      默认情况下,git fetch origin将会更新远程主机origin上所有分支,如果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

      如果省略远程分支名,则表示将本地分支推送与存在最终关系的远程分支,如果远程分支不存在,则会被创建;

      git push origin master,表示将本地master分支推送到origin主机的master分支;

      如果省略本地分支名,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需要通过shell登入主机并创建一个纯仓库,我们不妨以gitServer作为git用户和仓库所在的主机名,如果你在网络内部运行该主机,并且在DNS中设定gitServer指向该主机,则以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

    创建一个版本库仓库

    这样,其它人的克隆和推送也一样

    git clone git@gitServer:/test1.git
    vim README
    git commit -am ‘fix for the README file’
    git push origin master

    7. 作为一个额外的防护措施,可以用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,需要指明用户的登入shell为git-shell,而不是 bash 或者 csh,可以通过编辑/etc/passwd文件

    sudo vim /etc/passwd

    在文件末尾,找到类似此行

    git:x:1000:1000::/home/git:/bin/sh

    将bin/sh改为/usr/bin/git-shell

    git:x:1000:1000::/home/git:/usr/bin/git-shell

    现在git用户只能用ssh连接来推送和获取git仓库,而不能直接使用主机shell。
