Gitlab部署和基础使用
一. 环境准备
1.1 Ubuntu 环境
- 允许 root 远程 ssh 连接
~$ sudo su - root
[sudo] password for stevenux:
~# passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
~# vim /etc/ssh/sshd_config
...
PermitRootLogin yes
PasswordAuthentication yes
...
- 网络配置
root@gitlab-server:~# cat /etc/netplan/01-netcfg.yaml
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
version: 2
renderer: networkd
ethernets:
eth0:
dhcp4: no
dhcp6: no
addresses: [192.168.100.146/24]
gateway4: 192.168.100.2
nameservers:
addresses: [192.168.100.2, 223.6.6.6]
- 配置国内的软件源，比如：阿里云
root@gitlab-server:~# cat /etc/apt/sources.list
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
- 安装必要的库和基础工具
root@gitlab-server:~# apt update
root@gitlab-server:~# apt install iproute2 ntpdate tcpdump telnet traceroute nfs-kernel-server \
> nfs-common lrzsz tree openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev ntpdate \
> tcpdump telnet traceroute gcc openssh-server lrzsz tree openssl libssl-dev libpcre3 libpcre3-dev \
> zlib1g-dev ntpdate tcpdump telnet traceroute iotop unzip zip ipmitool -y
1.2 CentOS 环境
~# yum install vim gcc gcc-c++ wget net-tools lrzsz iotop lsof iotop bash-completion -y
~# yum install curl policycoreutils openssh-server openssh-clients postfix -y
~# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
~# systemctl disable firewalld
~# sed -i '/SELINUX/s/enforcing/disabled/' /etc/sysconfig/selinux
~# hostnamectl set-hostname gitlab.example.com
~# reboot
二. 安装 Gitlab
2.1 下载安装包安装并配置
官方 RPM 安装包下载地址
RPM 包国内下载地址
适用于 ubuntu 的.deb 包国内下载地址
2.1.1 下载并安装
root@gitlab-server:~# wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/ubuntu/pool/bionic/main/g/gitlab-ce/gitlab-ce_12.3.0-ce.0_amd64.deb
root@gitlab-server:~# dpkg -i gitlab-ce_12.3.0-ce.0_amd64.deb
Selecting previously unselected package gitlab-ce.

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
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
2.1.2 配置
gitlab 配置文件为：/etc/gitlab/gitlab.rb
root@gitlab-server:~# vim /etc/gitlab/gitlab.rb
root@gitlab-server:~# grep "^[a-Z]" /etc/gitlab/gitlab.rb
external_url 'http://192.168.100.146'
gitlab_rails['gitlab_email_from'] = '[email protected]'
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.qq.com"
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = "[email protected]"
gitlab_rails['smtp_password'] = "vbydcytaggtzbbag"
gitlab_rails['smtp_domain'] = "qq.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true
user['git_user_email'] = "[email protected]"
alertmanager['admin_email'] = '[email protected]'
2.1.3 初始化服务
执行刷新配置并启动服务：
使用 gitlab-ctl reconfigure 命令
root@gitlab-server:~# gitlab-ctl reconfigure
...
...
Recipe: gitlab::gitlab-rails
* execute[clear the gitlab-rails cache] action run
- execute /opt/gitlab/bin/gitlab-rake cache:clear
Recipe: <Dynamically Defined Resource>
* service[gitaly] action restart
- restart service service[gitaly]
Recipe: gitaly::enable

gitlab Reconfigured!
2.1.4 gitlab 命令行常用命令
gitlab-rails该命令用于启动控制台进行特殊操作，比如修改管理员密码、
打开数据库控台( gitlab-rails dbconsole)等。
# dbconsole 子命令进入postgreSQL数据库
root@gitlab-server:~# gitlab-rails dbconsole
psql (10.9)
Type "help" for help.
gitlabhq_production=> \db
List of tablespaces
Name | Owner | Location
------------+-------------+----------
pg_default | gitlab-psql |
pg_global | gitlab-psql |
(2 rows)
gitlabhq_production=>\quit
gitlab-psql进入数据库命令行
root@gitlab-server:~# gitlab-psql
psql (10.9)
Type "help" for help.
gitlabhq_production=# \db

2.1.5 验证 nginx 端口
nginx 的 80 端口是在初始化 gitlib 的时候启动的，因此如果之前的
有程序占用会导致初始化失败或无法访问！
root@gitlab-server:~# lsof -i:80
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 14408 root 8u IPv4 100257 0t0 TCP *:http (LISTEN)
nginx 14422 gitlab-www 8u IPv4 100257 0t0 TCP *:http (LISTEN)
nginx 14423 gitlab-www 8u IPv4 100257 0t0 TCP *:http (LISTEN)
2.1.6 登录 gitlab web 界面

2.4 创建组
2.4.1 创建一个组
使用管理员账户 root 创建一个开发组。一个组里面可以有多个项目分支，可以
将开发添加到组里面进行设置权限，不同的组就是公司不同的开发项目或者服务
模块，不同的组添加不同的开发即可实现对开发设置权限的管理。
Admin Area --> Dashboard --> New group

三. Git 基础使用
3.1 Gitlab 的数据保存方式
SVN 和 CVS
每次提交的文件都单独保存，即按照文件的提交时间区分不同的版本，保存至不同
的逻辑存储区域，后期恢复的时候直接基于之前版本恢复。
Gitlab
Gitlab 与 SVN 的数据保存方式不一样，gitlab 虽然也会在内部对数据进行逻辑划
分保存，但是当后期提交的数据如果和之前提交过的数据没有变化，其就直接快照之
前的文件，而不是在将文件重新上传一份在保存一遍，这样既节省了空间又加快了代
码提交速度。
3.2 Git 基础使用
git config --global user.name "name" # 设置全局用户名
git config --global user.email [email protected] # 设置全局邮箱
git config --global --list # 列出用户全局设置
git add index.html # 添加指定文件到暂存区
git commit -m "init" # 提交文件到工作区
git status # 查看工作区的状态
git push # 提交代码到服务器
git pull # 获取仓库代码到本地
git log # 查看操作日志
vim .gitignore # 定义忽略文件
git reset --hard HEAD^^ # git版本回滚， HEAD为当前版本，加一个^为上一个，^^为上上一个版本
git reflog # 获取每次提交的ID，可以使用--hard根据提交的ID进行版本回退
git reset --hard 5ae4b06 # 回退到指定id的版本
git branch # 查看当前所处的分支
git checkout -b develop # 创建并切换到一个新分支
git checkout develop # 切换分支
3.3 Git 基本概念
工作区：clone 的代码或者开发自己编写的代码文件所在的目录，通常是代码所在
的目录名称，也就是整个项目的根目录。
暂存区：用于存储在工作区中对代码进行修改后的文件所保存的地方，使用git add 添加。
本地仓库：用于提交存储在工作区和暂存区中改过的文件地方，使用 git commi 提交
远程仓库：多个开发共同协作提交代码的仓库，即 gitlab 服务器仓库
四. Gitlab 数据备份恢复
4.1 停止 Gitlab 相应的数据服务
停止 Gitlab 的数据服务需要停止两个组件：
Sidekiq: 是一个 Ruby 后台作业处理器，它从 Redis 队列中提取作业并进行处理。
后台作业允许 GitLab 通过将工作转移到后台来提供更快的请求/响应周期
Unicorn: 是一个 Ruby 应用服务器，用于运行核心 Rails 应用程序，该应用程序
在 GitLab 中提供面向用户的功能，其处理的请求来源于 nginx 的代理转发。
root@gitlab-server:~# gitlab-ctl stop unicorn
ok: down: unicorn: 0s, normally up
root@gitlab-server:~# gitlab-ctl stop sidekiq
ok: down: sidekiq: 0s, normally up
4.2 备份数据
使用gitlab-rake gitlab:backup:create命令就可以创建一个完整的 gitlab
备份，使用gitlab-rake gitlab:backup:restore命令恢复，迁移到其它的
gitlab 服务器恢复也可以，保持两台服务器的 gitlab 版本相同，注意备份文件
的权限即可。该命令会备份 gitlab 仓库、数据库、用户、用户组、用户密钥、
权限等信息。postgresql 等的配置文件时未备份的。
