1. GitLab簡介

GitLab 是一個(gè)用于倉庫管理系統(tǒng)的開源項(xiàng)目贤姆。使用Git作為代碼管理工具，并在此基礎(chǔ)上搭建起來的web服務(wù)并思÷可通過Web界面進(jìn)行訪問公開的或者私人項(xiàng)目。它擁有與Github類似的功能宋彼，能夠?yàn)g覽源代碼弄砍，管理缺陷和注釋∈涮椋可以管理團(tuán)隊(duì)對(duì)倉庫的訪問音婶，它非常易于瀏覽提交過的版本并提供一個(gè)文件歷史庫。團(tuán)隊(duì)成員可以利用內(nèi)置的簡單聊天程序(Wall)進(jìn)行交流莱坎。它還提供一個(gè)代碼片段收集功能可以輕松實(shí)現(xiàn)代碼復(fù)用衣式。

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`       配置你的URL在external_url選項(xiàng)里
configuration in /etc/gitlab/gitlab.rb file.                      通過這個(gè)文件里配置你的URL
Then, you can start your GitLab instance by running the following command:
  sudo gitlab-ctl reconfigure               用這個(gè)命令重新配置gitlab

For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md

[root@git ~]#: vim /etc/gitlab/gitlab.rb 
  13 external_url 'http://10.0.0.20'    配置你的ip地址
[root@git ~]#: gitlab-ctl reconfigure          

看到這個(gè)結(jié)果就顯示配置成功

Gitlab配置文件說明

gitlab‐ctl reconfigure # 更改配置文件后需重新配置
/opt/gitlab/ # gitlab的程序安裝目錄
/var/opt/gitlab # gitlab目錄數(shù)據(jù)目錄
/var/opt/gitlab/git‐dfata # 存放倉庫數(shù)據(jù)
gitlab‐ctl status # 查看目前gitlab所有服務(wù)運(yùn)維狀態(tài)
gitlab‐ctl stop # 停止gitlab服務(wù)
gitlab‐ctl stop nginx # 單獨(dú)停止某個(gè)服務(wù)
gitlab‐ctl tail # 查看所有服務(wù)的日志

Gitlab的服務(wù)構(gòu)成：

nginx： 靜態(tài)web服務(wù)器
gitlab‐workhorse: 輕量級(jí)的反向代理服務(wù)器
logrotate：日志文件管理工具
postgresql：數(shù)據(jù)庫
redis：緩存數(shù)據(jù)庫
sidekiq：用于在后臺(tái)執(zhí)行隊(duì)列任務(wù)（異步執(zhí)行）,（Ruby）
unicorn：An HTTP server for Rack applications婶博，GitLab Rails應(yīng)用是托管在這個(gè)服務(wù)器上面的。（Ruby
Web Server,主要使用Ruby編寫）

Gitlab漢化：

1荧飞、下載漢化補(bǔ)丁
[root@git ~]#:git clone https://gitlab.com/xhang/gitlab.git
2凡人、查看版本信息
[root@git ~]#: cat gitlab/VERSION
11.10.0
[root@git ~]#: cd gitlab
3、對(duì)比版本叹阔、生成補(bǔ)丁包
[root@git gitlab]#: git diff v11.10.0 v11.10.0-zh > ../11.10.0-zh.diff
4挠轴、停止服務(wù)器
gitlab‐ctl stop
5、打補(bǔ)丁
patch ‐d /opt/gitlab/embedded/service/gitlab‐rails ‐p1 < /root/11.10.0‐zh.diff
6耳幢、啟動(dòng)和重新配置
gitlab‐ctl start
gitlab‐ctl reconfigure

3. Gitlab配置

如果之前沒有g(shù)itlab岸晦，就要按照先創(chuàng)建組再創(chuàng)建項(xiàng)目，創(chuàng)建人員再添加到組里睛藻。也就是說項(xiàng)目屬于組的委煤，把要管理項(xiàng)目的人員也添加到組里，那這個(gè)人員就可以管理這個(gè)項(xiàng)目修档。

3.1 創(chuàng)建一個(gè)組

image.png

image.png

3.2 創(chuàng)建一個(gè)項(xiàng)目

image.png

image.png

image.png

這個(gè)就跟之前創(chuàng)建github的界面差不多了

3.3 刪除之前github創(chuàng)建的

[root@git ~]#: cd git_data/
[root@git git_data]#: git remote
origin
[root@git git_data]#: git remote remove origin
[root@git git_data]#: git remote

3.4 創(chuàng)建遠(yuǎn)程倉庫

[root@git git_data]#: git remote add origin git@10.0.0.20:test/git_data.git

3.5 添加ssh認(rèn)證并推送代碼

[root@git ~]#: cat .ssh/id_rsa.pub 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC41tBVR4hlbt3UBdRHDZrHlZWPVUtukum6Etseub4N826QhKeZ/BZmtJu/dUgi322odazuObUU6Z1ee5PV37DLREyayrevkcG/VwOycGaq4J78029wMW5Kq1mDvHGlXgw2x5kFl0s+6dtMSECudzuOAZYrS9QgaCP+h/hSB8JKD/rKW56QvEQ9hpK/wRdgF/xNgDao0EPxwjGgALZbIPYzu41jqGjFvavf1Ucu5EicJelw8ZDc6e3MQ8RvioC42vlroC87B/6tsQjLlp5Y1WZFBm9tpzgWoZ2EKhzRROC7LVEbPF98cM1o1DxL5kMfM7T3bP7G1dE8LrQ/3HsNk5NH root@git

我們這么做的目的就是實(shí)現(xiàn)共同開發(fā)，讓所有的開發(fā)人員都能連接帶我的gitlab

3.6 開通用戶

設(shè)置密碼

3.7 把用戶添加到組里

4. 開啟另外一臺(tái)jenkins服務(wù)器添加ssh

[root@jenkins ~]#: ssh-keygen -t rsa

添加ssh密鑰
克隆代碼

4.1 jenkins配置git

[root@jenkins git_data]#: git config --global user.email "dev@email.com"
[root@jenkins git_data]#: git config --global user.name "dev"

推送代碼

測(cè)試環(huán)境下gitlab默認(rèn)開啟了保護(hù)分支府框，不讓dev用戶推送代碼到master主分支上吱窝。
關(guān)閉保護(hù)分支在管理端操作

再次推送

5 保護(hù)分支

不允許開發(fā)用戶直接往master推送。只能推送到dev分支上迫靖，然后進(jìn)行請(qǐng)求合并院峡，用管理員用戶在進(jìn)行代碼合并。

5.1 創(chuàng)建dev分支推送代碼

[root@jenkins git_data]#: git checkout -b dev
Switched to a new branch 'dev'
[root@jenkins git_data]#: echo 22 >> test.txt 
[root@jenkins git_data]#: git commit -am 'add 2'

6 合并分支

6.1 第一次合并分支dev用戶操作

6.2 第二次合并

刪除dev用戶并切換到master

[root@jenkins git_data]#: git checkout master
Switched to branch 'master'
[root@jenkins git_data]#: git branch
  dev
* master
[root@jenkins git_data]#: git branch -d dev
warning: deleting branch 'dev' that has been merged to
         'refs/remotes/origin/dev', but not yet merged to HEAD.
Deleted branch dev (was 2562c60).
[root@jenkins git_data]#: git branch
* master

拉取新的代碼系宜，在創(chuàng)建因分支前一定要保持master代碼時(shí)最新的
