一、Gitlab概述
GitLab是一個利用 Ruby on Rails 開發的開源應用程序，實現一個自託管的Git項目倉庫，可通過Web界面進行訪問公開的或者私人項目。
GitLab擁有與Github類似的功能，能夠瀏覽源代碼，管理缺陷和註釋。可以管理團隊對倉庫的訪問，它非常易於瀏覽提交過的版本並提供一個文件歷史庫，
它還提供一個代碼片段收集功能可以輕鬆實現代碼複用，便於日後有需要的時候進行查找。
二、安裝及配置
1、環境準備
操作系統:CentOS release 6.8 (Final)
Gitlab軟件版本:gitlab-ce-9.3.0-ce.0.el6.x86_64.rpm
IP:192.168.66.102
2、關閉防火牆和設置iptables
Centos6.x
/etc/init.d/iptables stop
chkconfig iptables off
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
grep SELINUX=disabled /etc/selinux/config
setenforce 0
Centos7.x
systemctl stop firewalld.service
systemctl disable firewalld.service
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
grep SELINUX=disabled /etc/selinux/config
setenforce 0

3、使用yum源安裝
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
也可以使用國yum源，速度會快點
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.key
4、啓動及配置gitlab服務
gitlab-ctl reconfigure
漫長的等待.................................
5、gitlab常用管理
gitlab-ctl start
gitlab-ctl restart
gitlab-ctl stop
配置完成之後端口查看狀態（需要用到80端口）
gitlab-ctl status
