简介：

GitLab是利用Ruby on Rails一个开源的版本管理系统，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，与Github类似。

基本服务构成

• Nginx：静态web服务器。
• gitlab-shell：用于处理Git命令和修改authorized keys列表。
• gitlab-workhorse: 轻量级的反向代理服务器。
• 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）。
• unicorn：An HTTP server for Rack applications，GitLab Rails应用是托管在这个服务器上面的

  yum安装

• 配置Yum源

vim /etc/yum.repos.d/gitlab-ce.repo
[gitlab-ce]
name=Gitlab CE Repository
baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever
gpgcheck=0
enabled=1

• 更新Yum缓存

  yum makecache

  安装Gitlab社区版

  yum intall gitlab-ce        #自动安装最新版
  yum install gitlab-ce-x.x.x    #安装指定版本

  Gitlab常用命令

  gitlab-ctl start    # 启动所有 gitlab 组件；
  gitlab-ctl stop        # 停止所有 gitlab 组件；
  gitlab-ctl restart        # 重启所有 gitlab 组件；
  gitlab-ctl status        # 查看服务状态；
  gitlab-ctl reconfigure        # 启动服务；
  vim /etc/gitlab/gitlab.rb        # 修改默认的配置文件；
  gitlab-rake gitlab:check SANITIZE=true --trace    # 检查gitlab；
  gitlab-ctl tail        # 查看日志；

  Gitlab配置

  vi /etc/gitlab/gitlab

  # 登陆URL
  external_url 'http://10.10.30.109'
  # 时区
  gitlab_rails['time_zone'] = 'Asia/Shanghai'
  # smtp发件服务器
  gitlab_rails['smtp_enable'] = true
  gitlab_rails['smtp_address'] = "smtp.xxx.com"
  gitlab_rails['smtp_port'] = 465
  gitlab_rails['smtp_user_name'] = "xxx@xxx.com"
  gitlab_rails['smtp_password'] = "xxx"
  gitlab_rails['smtp_domain'] = "smtp.xxx.com"
  gitlab_rails['smtp_authentication'] = "login"
  gitlab_rails['smtp_enable_starttls_auto'] = true
  gitlab_rails['smtp_tls'] = true
  gitlab_rails['gitlab_email_enabled'] = true
  gitlab_rails['gitlab_email_from'] = 'xxx@xxx.com'
  gitlab_rails['gitlab_email_display_name'] = 'gitlab'
  # gitlab 自动备份
  gitlab_rails['manage_backup_path'] = true
  gitlab_rails['backup_path'] = "/data/backups/gitlab"
  gitlab_rails['backup_archive_permissions'] = 0644
  gitlab_rails['backup_keep_time'] = 7776000
  # gitlab数据存储目录
  git_data_dirs({
  "default" => {
   "path" => "/data/git-data"
  }
  })
  # gitlab_shell ssh端口
  gitlab_rails['gitlab_shell_ssh_port'] = 22

  Gitlab 使用

• Gitlab自动备份脚本

  [root@gitlab-30 ~]# cat /data/backups/gitlab/gitlab_backup.sh
  #/bin/sh
  /opt/gitlab/bin/gitlab-rake gitlab:backup:create CRON=1

• 每天凌晨两点自动备份

  0 2 * * * /bin/bash -x /data/backups/gitlab/gitlab_backup.sh  > /dev/null 2>&1

• Gitlab默认密码：

  
  [root@gitlab-30 ~]# cat /etc/gitlab/initial_root_password
  # WARNING: This value is valid only in the following conditions
  #          1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails['initial_root_password']` setting in `gitlab.rb`, it was provided before database was seeded for the first time (usually, the first reconfigure run).
  #          2. Password hasn't been changed manually, either via UI or via command line.
  #
  #          If the password shown here doesn't work, you must reset the admin password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.

Password: Ngkq54yCjmUq1S+3X5WTt/yq21N+sKJfFsP2n62tAOU=

NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.
