一、Gitlab概述
GitLab是一个利用 Ruby on Rails 开发的开源应用程序，实现一个自托管的Git项目仓库，可通过Web界面进行访问公开的或者私人项目。
GitLab拥有与Github类似的功能，能够浏览源代码，管理缺陷和注释。可以管理团队对仓库的访问，它非常易于浏览提交过的版本并提供一个文件历史库，
它还提供一个代码片段收集功能可以轻松实现代码复用，便于日后有需要的时候进行查找。二、安装及配置
1、环境准备
操作系统:CentOS release 6.8 (Final)
Gitlab软件版本:gitlab-ce-9.3.0-ce.0.el6.x86_64.rpm
IP:172.16.8.112、关闭防火及SELinux
可以参考如下:
http://blog.csdn.net/xiegh2014/article/details/530317813、使用yum源安装
rpm -ivh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm
yum install curl policycoreutils openssh-server openssh-clients postfix -y
curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
yum install -y gitlab-ce
yum install -y git也可以使用国yum源，速度会快点
vim /etc/yum.repos.d/gitlab-ce.repo
[gitlab-ce]
name=gitlab-ce
baseurl=http://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7
repo_gpgcheck=0
gpgcheck=0
enabled=1
gpgkey=https://packages.gitlab.com/gpg.key4、启动及配置gitlab服务
gitlab-ctl reconfigure
漫长的等待.................................5、gitlab常用管理
gitlab-ctl start
gitlab-ctl restart
gitlab-ctl stop配置完成之后端口查看状态（需要用到80端口）
gitlab-ctl status
