Git 仓库 SSH、HTTP、Gitweb (Nginx)

转载：https://www.cnblogs.com/wangxiaoqiangs/p/6179610.html

需要安装：yum -y gcc automake epel-release install fcgi-devel

简介:

自己搭建 Git 仓库，实现 SSH 协议、配合 Nginx 实现 HTTP 协议拉取、推送代码。

利用 Nginx 实现 Gitweb 在线浏览代码，使用 Gitweb-theme 更新默认 Gitweb 样式。

一、安装 Git

shell > yum -y install git

shell > git --version  # yum 安装的 git 版本比较低，所以我选择源码编译的方式安装
git version 1.7.1

shell > yum -y remove git

shell > yum -y install perl cpio autoconf tk zlib-devel libcurl-devel openssl-devel expat-devel gettext-devel perl-ExtUtils-MakeMaker

shell > cd /usr/local/src; wget https://www.kernel.org/pub/software/scm/git/git-2.10.0.tar.gz

shell > tar zxf git-2.10.0.tar.gz && cd git-2.10.0

shell > autoconf && ./configure && make && make install

shell > git --version
git version 2.10.0

 

二、Git SSH 协议

1、创建 Git 仓库

shell > mkdir -p /data/git && cd /data/git

shell > git init --bare sample.git

2、客户端 clone 仓库

shell > git config --global color.ui true
shell > git config --global user.name 'wang'
shell > git config --global user.email '[email protected]'

# 初始化 git 客户端

shell > git clone [email protected]:/data/git/sample.git  # 输入 1.22 的 root 密码  
[email protected]'s password: 

shell > cd sample
shell > cp /etc/passwd .
shell > git add passwd
shell > git commit -m 'add passwd'
shell > git push -u origin master

shell > git status
# On branch master
nothing to commit (working directory clean)

# 已经将新增的文件 passwd 提交到了远程 git 仓库的 master 分支

shell > rm -rf sample
shell > git clone [email protected]:/data/git/sample.git
[email protected]'s password: 

shell > ls sample
passwd

# 这就实现了 SSH 本地用户授权访问 git 仓库
# 如果 SSH 非标准端口时，需要这样访问：git clone ssh://[email protected]:16543/data/git/sample.git
# 现在你想把 git 仓库 sample.git 授权别人访问，怎么办？
# 首先你得给每个人创建用户，他们才能 clone 代码，但是不能写入。
# 其次你要把这些用户加入到一个组，然后把 sample.git 属组改为这个组，并且给这个组写入权限。
# 或者创建一个公共用户，修改 git 仓库 sample.git 属主为这个公共用户，然后大家都使用这个用户访问代码库。

三、Git HTTP 协议

1、创建、配置 Git 仓库

shell > useradd -r -s /sbin/nologin www-data  # 创建运行用户

shell > mkdir -p /data/git && chown www-data.www-data /data/git && cd /data/git

shell > git init --bare sample.git && chown -R www-data.www-data sample.git

shell > cd sample.git && mv hooks/post-update.sample hooks/post-update

shell > git update-server-info

2、安装、配置 Nginx ( 使其支持 CGI )

shell > cd /usr/local/src
shell > git clone https://github.com/lighttpd/spawn-fcgi.git
shell > cd spawn-fcgi && ./autogen.sh && ./configure && make && make install

shell > yum -y install fcgi-devel

shell > cd /usr/local/src
shell > git clone https://github.com/gnosek/fcgiwrap.git
shell > cd fcgiwrap && autoreconf -i && ./configure && make && make install

shell > vim /etc/init.d/fcgiwrap  # 配置启动脚本

#! /bin/bash

    auth_basic_user_file /usr/local/nginx-1.10.2/conf/pass.db;

    location ~ ^.*\.git/objects/([0-9a-f]+/[0-9a-f]+|pack/pack-[0-9a-f]+.(pack|idx))$ {

# 自己按需修改 nginx.conf，user www-data www-data; 不要忘记加入 include vhost/*.conf;
# 注意 认证文件 pass.db 路径
# 注意 git-http-backend 路径
# 第一个 location 用于静态文件直接读取
# 第二个 location 用于将指定动作转给 cgi 执行
# 根目录指向 git 仓库目录

shell > /usr/local/nginx-1.10.2/sbin/nginx

shell > yum -y install httpd-tools  # 安装 htpasswd 命令

shell > cd /usr/local/nginx-1.10.2/conf

shell > htpasswd -c pass.db wang  # 添加用户时执行 htpasswd pass.db username

3、客户端 clone

shell > git config --global color.ui true
shell > git config --global user.name 'wnag'
shell > git config --global user.email '[email protected]'

# 初始化 git 客户端

shell > git clone http://git.server.com/sample.git  # 输入用户名、密码即可
正克隆到 'sample'...
Username for 'http://git.server.com': wang
Password for 'http://[email protected]': 
warning: 您似乎克隆了一个空仓库。

shell > cd sample.git
shell > cp /etc/passwd .
shell > git add passwd
shell > git commit -m 'add passwd'
shell > git push
Username for 'http://git.server.com': wang
Password for 'http://[email protected]':

# htpasswd 创建新用户，就可以协作了。

四、Gitweb 在线代码预览

# 按照我的方法安装 Git ，Gitweb 已经集成了，我们要做的就是找到并配置 Gitweb 。

shell > /usr/local/share/gitweb  # Gitweb 路径

shell > ls /usr/local/share/gitweb  # gitweb.cgi 脚本、static 这是个目录，里面是静态文件 css 、js 、logo 等
gitweb.cgi  static

shell > vim /etc/gitweb.conf  # 生成配置文件

# path to git projects (.git)
$projectroot = "/data/git";

# directory to use for temp files
$git_temp = "/tmp";

# target of the home link on top of all pages
$home_link = $my_uri || "/";

# html text to include at home page
$home_text = "indextext.html";

# file with project list; by default, simply scan the projectroot dir.
$projects_list = $projectroot;

# javascript code for gitweb
$javascript = "static/gitweb.js";

# stylesheet to use
$stylesheet = "static/gitweb.css";

# logo to use
$logo = "static/git-logo.png";

# the 'favicon'
$favicon = "static/git-favicon.png";

# 注意 Git 仓库路径、静态文件路径

shell > /usr/local/share/gitweb/gitweb.cgi  # 手动执行开是否报错，Status: 200 OK 正常，以下为报错及解决方法

# 全局中指定了 gitweb 根目录，最后配置区域加入了 gitweb 的相关配置。
# 现在浏览器访问 git.server.com 就可以预览 Git 代码库及其中的代码了。

五、Gitweb-theme 样式

# 如果觉得 gitweb 默认样式不好看，可以拿该样式替换

shell > cd /usr/local/src
shell > git clone https://github.com/kogakure/gitweb-theme.git
shell > cd gitweb-theme
shell > ./setup -vi -t /usr/local/share/gitweb --install  # -t 指定 gitweb 根目录，一路 y 即可

# 这时刷新浏览器，就会发现界面的变化
