Git是一款注重速度、数据完整性、分布式支持和非线性工作流的分布式版本控制工具。Git最初由Linus Torvalds在2005年为Linux内核开发而设计，如今已经成为被广泛接受的版本控制系统。
和其他大多数分布式版本控制系统比起来，不像大多数客户端-服务端的系统，每个Git工作目录是一个完整的仓库，带有完整的历史记录和完整的版本跟踪能力，不需要依赖网络或者中心服务器。像Linux内核一样，Git也是在GPLv2许可证下分发的自由软件。
本篇教程我会演示如何安装 gitlit 服务器。gitlit的最新稳定版是1.6.2。Gitblit是一款开源、纯Java开发的用于管理、浏览和提供Git仓库服务的软件。它被设计成一款为希望托管中心仓库的小型工作组服务的工具。
mkdir -p /opt/gitblit; cd /opt/gitblit; wget http://dl.bintray.com/gitblit/releases/gitblit-1.6.2.tar.gz
列出解压后目录内容：
root@vps124229 [/opt/gitblit]# ls
./ docs/ gitblit-stop.sh* LICENSE service-ubuntu.sh*
../ ext/ install-service-centos.sh* migrate-tickets.sh*
add-indexed-branch.sh* gitblit-1.6.2.tar.gz install-service-fedora.sh* NOTICE
authority.sh* gitblit.jar install-service-ubuntu.sh* reindex-tickets.sh*
data/ gitblit.sh* java-proxy-config.sh* service-centos.sh*
默认配置文件在data/gitblit.properties，你可以根据需要自己修改。
启动gitlit服务：
通过service命令：
root@vps124229 [/opt/gitblit]# cp service-centos.sh /etc/init.d/gitblit
root@vps124229 [/opt/gitblit]# chkconfig --add gitblit
root@vps124229 [/opt/gitblit]# service gitblit start
Starting gitblit server
.
手动启动：
root@vps124229 [/opt/gitblit]# java -jar gitblit.jar --baseFolder data
