創建用戶
[kiosk@foundation6 ~]$ git config --global user.name "bobo"
[kiosk@foundation6 ~]$ git config --global user.email  [e-mail]
查看用戶信息
[root@foundation15 ~]# cat .gitconfig

    name = bobo
    email = [e-mail]

搭建倉庫
[root@foundation15 mnt]# mkdir  bobo
[root@foundation15 mnt]# cd  bobo
[root@foundation15 bobo]# ls
[root@foundation15 bobo]# git init

倉庫存放代碼
[root@foundation15 bobo]# vim   bobo.txt
[root@foundation15 bobo]# git add bobo.txt 
[root@foundation15 bobo]# git status 
# On branch master
# Initial commit
# Changesto be committed:
#   (use "git rm --cached <file>..." to unstage)
#   new file:   bobo.txt（顯示新的文件已經添加）

commit來提交
[root@foundation15 bobo]# git commit -m "demo"

版本的回退
[root@foundation15 bobo]# git log
commit 282b01d3a25a0a5a0343019dab8034322e0e89e3

#######################################################################
git reset 回退已經提交的倉庫
HEAD 表示當前版本
HEAD^ 表示上一個版本
HEAD^^ 表示上上一個版本
HEAD~100 表示當前往上100個版本 
######################################################################

[root@foundation15 bobo]# git reset --hard HEAD^
HEAD is now at 69d20ec demo
查看代碼已經改變
[root@foundation15 bobo]# cat  bobo.txt 
hello

如果版本回退後需要返回回退前  指定回退版本號就可以了
[root@foundation15 bobo]# git reset --hard 282b01d3a25a0a5a0343019dab8034322e0e89e3
HEAD is now at 282b01d hello
###############################################################
對於所有的出現過的版本號 可以通過  relog查看
[root@foundation15 bobo]# git reflog
282b01d HEAD@{0}: reset: moving to 282b01d3a25a0a5a0343019dab8034322e0e89e3

工作區和贊存區

• Git版本庫裏添加的時候，是分兩步執行的：

• 第一步是用git add把文件添加進去，實際上就是把文件修改添加到暫存區；

• 第二步是用git commit提交更改，實際上就是把暫存區的所有內容提交到當前分支。

• 因爲我們創建Git版本庫時，Git自動爲我們創建了唯一一個master分支，所以，現在，git commit就是往master分支上提交更改。
  所以說明需要提交的文件修改通通放到暫存區，然後，一次性提交暫存區的所有修改

1
    對於還沒有add的代碼  修改後撤回的操作爲
[root@foundation15 bobo]# > bobo.txt 
[root@foundation15 bobo]# cat  bobo.txt 
[root@foundation15 bobo]# git  checkout  bobo.txt 
[root@foundation15 bobo]# cat  bobo.txt 
wetos

2
對於修改後還沒有commit的代碼撤回
[root@foundation15 bobo]# > bobo.txt 
[root@foundation15 bobo]# cat  bobo.txt 
[root@foundation15 bobo]# git add *
[root@foundation15 bobo]# cat bobo.txt 
[root@foundation15 bobo]# git reset HEAD  bobo.txt （將文件退回工作區）
Unstaged changes after reset:
M   bobo.txt
[root@foundation15 bobo]# git checkout  bobo.txt 
[root@foundation15 bobo]# cat bobo.txt 
wetos

3 
對於提交後的代碼 只能通過版本回退來恢復了

Gitlab的安裝及使用

**

使用rpm包方式安裝

[root@foundation15 ~]# yum install  gitlab-ce-11.0.1-ce.0.el6.x86_64.rpm 
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Examining gitlab-ce-11.0.1-ce.0.el6.x86_64.rpm: gitlab-ce-11.0.1-ce.0.el6.x86_64
Marking gitlab-ce-11.0.1-ce.0.el6.x86_64.rpm to be installed

#############################################################
初始化配置 
修改配置文件
[root@foundation15 yum.repos.d]# vim  /etc/gitlab/gitlab.rb 
external_url 'http://172.25.15.250'


開始初始化gitlab
[root@foundation15 yum.repos.d]# gitlab-ctl reconfigure
等待初始化

啓動 再瀏覽器進行ssh等配置

物理機ssh-keygen創建 id_rsa.pub

ssh配置完成

測試 創建一個項目用於本地測試拉取

創建一個bobo組 再創建一個test項目 再寫東西進去就可以了

測試使用ssh免密拉取項目

[root@foundation15 mnt]# git clone [email protected]:bobo/test1.git
Cloning into 'test1'...
remote: Counting objects: 3, done.
remote: Total 3 (delta 0), reused 0 (delta 0)
Receiving objects: 100% (3/3), done.

查看拉取內容
[root@foundation15 test1]# cat test1 
bobo

與網頁創建的一致
倉庫搭建完成

git 代碼上傳

創建一個index.html

[root@foundation15 test1]# git add *
[root@foundation15 test1]# git commit -m "add index.html"
[master af7e6dc] add index.html
 1 file changed, 1 insertion(+)
 create mode 100644 index.html
[root@foundation15 test1]# ls
index.html  test1
#####################################################################3
git  push就可以提交代碼
[root@foundation15 test1]# git push
warning: push.default is unset; its implicit value is changing in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the current behavior after the default changes, use:

  git config --global push.default matching

To squelch this message and adopt the new behavior now, use:

  git config --global push.default simple

See 'git help config' and search for 'push.default' for further information.
(the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
'current' instead of 'simple' if you sometimes use older versions of Git)

Jenkins的搭建與使用

**

1. 基於JAVA的開源的自動化系統平臺

2. 加速自動化CI，CD任務及流水線,所有類型的任務：構建，測試，部署等

3. 豐富的插件生態系統支持功能擴展，1400+插件和SCM，測試，通知，報

告，Artfact，觸發，外部集成等，基於Web的管理和使用界面

安裝使用
本次使用docker來搭建

拉取鏡像
[root@foundation15 ~]# docker pull jenkins:latest
latest: Pulling from library/jenkins
～～～～～～～～
Digest: sha256:eeb4850eb65f2d92500e421b430ed1ec58a7ac909e91f518926e02473904f668
Status: Downloaded newer image for jenkins:latest
拉取後可以保存下來  主機更換後不用再下載

[root@foundation15 mnt]# docker save -o  jenkins.tar   jenkins

[root@foundation15 mnt]# ll jenkins.tar 
-rw------- 1 root root 714778112 Aug 23 09:16 jenkins.tar


開啓服務
需要注意  再一臺物理機運行 gitlab與jenkins時 他們的端口都是相同的  所以這裏將 8888作爲jenkins的使用端口
[root@foundation15 mnt]# docker run -it --name jenkins1 -v $HOME/jenkins:/var/  -p 8888:8080 -p 55000:50000 -p 45000:45000 jenkins:latest 
Running from: /usr/share/jenkins/jenkins.war

再瀏覽器中打開
http://172.25.15.250:8888 設置密碼登陸即可

當出現unlock時

根據提示在對應目錄下找到解鎖碼輸入即可
我在docker中搭建的服務 所以進入docker查看即可

解鎖後設置密碼即可

搭建項目來鏈接gitlab

創建新的項目來接受gitli的信息

選擇gitlib

添加認證 輸入gitlab的用戶密碼

再添加選擇gitlab的http與版本即可即可

[root@foundation15 ~]# rpm -qa|grep gitlab
gitlab-ce-11.0.1-ce.0.el6.x86_64

選擇構建的操作 這裏選擇輸出代碼文件
選擇構建的刷新時間

保存退出

開始構建

顯示控制檯即可

基本的搭建完成

開始測試 本地主機上傳新代碼

[root@foundation15 test1]# git add *
[root@foundation15 test1]# git commit -m "add  bobo.txt"
[master 9df3cb8] add  bobo.txt
 1 file changed, 1 insertion(+)
 create mode 100644 bobo.txt

   0c28b4d..9df3cb8  master -> master

等待代碼構建添加即可

搭建成功

實時觸發器
下載gitlibhook插件即可

在配置時打開高級選項 生成key 將網址 一併複製在gitlab上

出現無法訪問本地時
在useradmin settting中 找到最下方的設置打開即可

測試是否添加成功

返回值200 成功
添加新代碼文件測試是否ok

[root@foundation15 test1]# vim   hello.txt
[root@foundation15 test1]# git add *
[root@foundation15 test1]# git commit  -m "add"
[master c06e5c1] add
