在当今快速发展的互联网时代，版本控制系统如Git已成为软件开发中不可或缺的一部分，它不仅帮助开发者有效管理代码变更历史，还促进了团队协作和项目交付的效率，而在众多Linux发行版中，Ubuntu以其稳定性、易用性和广泛的社区支持而受到开发者的喜爱，本文将详细阐述如何在Ubuntu系统上搭建一个功能齐全的Git服务器，以供本地或远程开发团队使用。

一、准备工作

在开始之前，确保你的Ubuntu系统已经更新到最新版本，并且安装了必要的软件包，可以使用以下命令进行更新：

sudo apt-get update
sudo apt-get upgrade

为了安全起见，建议禁用root登录并设置一个强密码，可以通过以下命令实现：

sudo passwd root

二、安装Git

我们需要安装Git，打开终端，输入以下命令进行安装：

sudo apt-get install git

安装完成后，可以通过以下命令检查Git是否安装成功：

git --version

如果显示了Git的版本号，说明安装成功。

三、配置SSH密钥

为了安全地访问Git服务器，我们需要为每个用户生成一对SSH密钥，禁用密码验证：

ssh-keygen -t rsa -b 4096 -C "your.email@example.com"

将公钥复制到~/.ssh/authorized_keys文件中（记得替换user为你的实际的用户名称）：

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

将私钥添加到~/.ssh/config文件中，以便将来直接使用用户名登录：

echo "UserKnownHostsFile /dev/null" >> ~/.ssh/config
echo "StrictHostKeyChecking no" >> ~/.ssh/config

四、创建Git仓库

现在我们已经配置好了SSH密钥，接下来就是创建Git仓库，创建一个目录来存储你的项目代码：

mkdir myproject.git && cd myproject.git/

然后初始化一个新的Git仓库：

git init --bare --shared=group --progress --recurse-submodules --depth=1 --prefix=myproject .git/HEAD:refs/heads/master .git/config:config .git/logs:logs .git/info:info .git/info/exclude:info-exclude .git/info/grafts:info-grafts .git/hooks:hooks .git/objects:objects .git/refs:refs .git/refs/heads:refs-heads .git/refs/tags:refs-tags .git/trees:trees .git/index:index .git/packed-refs:packed-refs 8080:http://localhost:8080 4043:https://localhost:4043 22:https://localhost:22 tmp:tmp user@localhost:user@localhost user@localhost+123::user@localhost+123 user@localhost%40example.com::user@localhost%40example.com user@localhost %7Emyproject%7E::user@localhost %7Emyproject%7E user@localhost %7Emyproject%7E %7Emyproject%7E::user@localhost %7Emyproject%7E %7Emyproject%7E::user@localhost %7Emyproject%7E user@localhost +file1::file1 user@localhost +file2::file2 user@localhost +file3::file3 user@localhost +file4::file4 user@localhost +file5::file5 user@localhost +file6::file6 user@localhost +file7::file7 user@localhost +file8::file8 user@localhost +file9::file9 user@localhost +file10::file10 user@localhost +file11::file11 user@localhost +file12::file12 user@localhost +file13::file13 user@localhost +file14::file14 user@localhost +file15::file15 user@localhost +file16::file16 user@localhost +file17::file17 user@localhost +file18::file18 user@localhost +file19::file19 user@localhost +file20::file20 user@localhost +file21::file21 user@localhost +file22::file22 user@localhost +file23::file23 user@localhost +file24::file24 user@localhost +file25::file25 user@localhost +file26::file26 user@localhost +file27::file27 user@localhost +file28::file28 user@localhost +file29::file29 user@localhost +file30::file30 user@localhost +file31::file31 user@localhost +file32::file32 user@localhost +file33::file33 user@localhost + file40:: file40" >> .git/config ## Add and commit initial repository data to therepo directory, then create therepo subdirectory and add it to.gitignore in that directory to ignore this subdirectory from future commit operations. This is useful for managing large projects with multiple developers on a single machine, or for creating a private repository that you can share with others while keeping the actual code files private. For example, if you have a project namedmyproject, you might want to use--bare option to initialize a bare repository atmyproject.git directory, and then add your project code tomyproject directory outside ofmyproject.git directory, and finally addmyproject directory to.gitignore insidemyproject.git directory to ignore it from future commit operations. This will allow you to keep your project code separate from your repository configuration, and make it easier to manage and share your project with others without revealing your repository configuration details.
