【GitLab 介绍】
GitLab 是一个基于 Git 实现的在线代码仓库托管软件，你可以用 gitlab 自己搭建一个类似于 Github 一样的系统，一般用于在企业、学校等内部网络搭建 git 私服。
功能：Gitlab 是一个提供代码托管、提交审核和问题跟踪的代码管理平台。对于软件工程质量管理非常重要。
版本：GitLab 分为社区版（CE） 和企业版（EE）。
配置：建议CPU2核，内存2G以上。
Gitlab 的服务构成：
Nginx：静态 web 服务器。
gitlab-shell：用于处理 Git 命令和修改 authorized keys 列表。（Ruby）
gitlab-workhorse: 轻量级的反向代理服务器。（go）
GitLab Workhorse 是一个敏捷的反向代理。它会处理一些大的 HTTP 请求，比如文件上传、文件下载、Git push/pull 和 Git 包下载。其它请求会反向代理到 GitLab Rails 应用，即反向代理给后端的 unicorn。
logrotate：日志文件管理工具。
postgresql：数据库。
redis：缓存数据库。
sidekiq：用于在后台执行队列任务（异步执行）。（Ruby）
unicorn：An HTTP server for Rack applications，GitLab Rails 应用是托管在这个服务器上面的。（Ruby Web Server，主要使用 Ruby 编写）

Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
sudo gitlab-ctl reconfigure
For a comprehensive list of configuration options please see the Omnibus GitLab readme

【配置】
# 修改 gitlab 配置文件
# 先关闭 gitlab 服务
gitlab-ctl stop
# gitlab 默认监听 80 端口，修改服务器自定义端口
# 第一处
vi /opt/gitlab/embedded/conf/nginx.conf
36 listen 666;
37 server_name localhost;
# 第二处
vi /etc/gitlab/gitlab.rb
29 # external_url 'http://gitlab.example.com'
# 将 external_url 变量的地址修改为 gitlab 所在 centos 的 ip 地址
30 external_url 'http://8.8.8.8'
765 ### Advanced settings
766 # unicorn['listen'] = 'localhost'
767 unicorn['port'] = 666
768 # unicorn['socket'] = '/var/opt/gitlab/gitlab-rails/sockets/gitlab.socket'
769 # unicorn['pidfile'] = '/opt/gitlab/var/unicorn/unicorn.pid'
770 # unicorn['tcp_nopush'] = true
771 # unicorn['backlog_socket'] = 1024【重新配置】
