一、CICD是什么
CI/CD是指持续集成(Continuous Integration)和持续部署(Continuous Deployment)或持续交付(Continuous Delivery)
1.1 持续集成(Continuous Integration)
持续集成是一种软件开发实践,团队成员频繁地将他们的工作集成到共享的代码仓库中。其主要特点包括:
-
频繁提交代码:开发人员可以每天多次提交代码,确保代码库始终保持最新状态。
-
自动化构建:每次提交后,自动触发构建过程,包括编译、测试、静态分析等。
-
快速反馈:如果构建失败或测试不通过,能够快速地向开发人员提供反馈,以便及时修复问题。
1.2 持续部署(Continuous Deployment)
持续部署是在持续集成的基础上,将通过所有测试的代码自动部署到生产环境中。其特点如下:
-
自动化流程:从代码提交到生产环境的部署完全自动化,无需人工干预。
-
高频率部署:可以实现频繁的部署,使得新功能能够快速地提供给用户。
-
风险控制:需要有强大的测试和监控体系来确保部署的稳定性和可靠性。
1.3 持续交付(Continuous Delivery)
持续交付与持续部署类似,但不一定自动部署到生产环境,而是随时可以部署。其重点在于确保软件随时处于可发布状态。
CI/CD 的好处包括:
-
提高开发效率:减少手动操作和等待时间,加快开发周期。
-
尽早发现问题:通过频繁的集成和测试,问题能够在早期被发现和解决。
-
降低风险:减少了大规模部署时可能出现的问题,提高了软件的质量和稳定性。
-
增强团队协作:促进团队成员之间的沟通和协作,提高团队的整体效率。
常见的 CI/CD 工具包括 Jenkins、GitLab CI/CD、Travis CI 等。这些工具可以帮助团队实现自动化的构建、测试和部署流程。
二、git工具使用
2.1 git简介
Git 是一个分布式版本控制系统,被广泛用于软件开发中,以管理代码的版本和变更。 主要特点:
-
分布式
-
每个开发者都有完整的代码仓库副本,这使得开发者可以在离线状态下进行工作,并且在网络出现问题时也不会影响开发。
-
即使中央服务器出现故障,开发者仍然可以在本地进行开发和查看项目历史。
-
-
高效的分支管理
-
Git 中的分支创建和切换非常快速和简单。开发人员可以轻松地创建新的分支来进行新功能的开发或修复 bug,而不会影响主分支。
-
合并分支也相对容易,可以使用多种合并策略来满足不同的需求。
-
-
快速的版本回退
-
如果发现某个版本存在问题,可以快速回退到之前的版本。
-
可以查看每个版本的详细变更记录,方便了解代码的演进过程。
-
-
强大的提交管理
-
每个提交都有一个唯一的标识符,可以方便地引用和查看特定的提交。
-
提交可以包含详细的提交信息,描述本次提交的更改内容。
-
-
支持协作开发
-
开发者可以将自己的更改推送到远程仓库,供其他开发者拉取和合并。
-
可以处理多个开发者同时对同一文件进行修改的情况,通过合并冲突解决机制来确保代码的完整性。
-
Git必看秘籍:https://git-scm.com/book/zh/v2
2.2 git的工作流程
Git 有三种状态:已提交(committed)、已修改(modified) 和 已暂存(staged)。
-
已修改表示修改了文件,但还没保存到数据库中。
-
已暂存表示对一个已修改文件的当前版本做了标记,使之包含在下次提交的快照中。
-
已提交表示数据已经安全地保存在本地数据库中。
这会让我们的 Git 项目拥有三个阶段:工作区、暂存区以及 Git 目录。
2.3 部署git
2.3.1 安装git
[root@getlab-node1 ~]# dnf install git -y
设定命令补全功能:
[root@getlab-node1 ~]# echo "source /usr/share/bash-completion/completions/git" >> ~/.bashrc
[root@getlab-node1 ~]# source ~/.bashrc
[root@getlab-node1 ~]#
2.3.2 初始化
获取 Git 仓库通常有两种方式:
-
将尚未进行版本控制的本地目录转换为 Git 仓库。
-
从其它服务器克隆 一个已存在的 Git 仓库。比如: git clone
初始化版本库
[root@getlab-node1 ~]# mkdir xiaoding
[root@getlab-node1 ~]# cd xiaoding/
[root@getlab-node1 xiaoding]#
[root@getlab-node1 xiaoding]#
[root@getlab-node1 xiaoding]# git init
hint: Using 'master' as the name for the initial branch. This default branch name
hint: is subject to change. To configure the initial branch name to use in all
hint: of your new repositories, which will suppress this warning, call:
hint:
hint: git config --global init.defaultBranch <name>
hint:
hint: Names commonly chosen instead of 'master' are 'main', 'trunk' and
hint: 'development'. The just-created branch can be renamed via this command:
hint:
hint: git branch -m <name>
Initialized empty Git repository in /root/xiaoding/.git/
[root@getlab-node1 xiaoding]# ls -a
. .. .git
[root@getlab-node1 xiaoding]#
[root@getlab-node1 xiaoding]# ls .git/
branches config description HEAD hooks info objects refs
[root@getlab-node1 xiaoding]#
设定用户信息:
[root@getlab-node1 xiaoding]# git config --global user.name "xiaoding"
[root@getlab-node1 xiaoding]# git config --global user.email "xiaoding@xiaoding.org"
[root@getlab-node1 xiaoding]#
查看当前文件状态:
[root@getlab-node1 xiaoding]# git status
On branch master
No commits yet
nothing to commit (create/copy files and use "git add" to track)
[root@getlab-node1 xiaoding]#
[root@CICD-node1 timinglee]# git status -s #简化输出
2.3.3 git的使用方法
2.3.3.1 常用方法
[root@getlab-node1 xiaoding]# echo xiaoding > README.md
[root@getlab-node1 xiaoding]# git status
On branch master
No commits yet
Untracked files:
(use "git add <file>..." to include in what will be committed)
README.md
nothing added to commit but untracked files present (use "git add" to track)
[root@getlab-node1 xiaoding]# git status -s
?? README.md #?? 新建文件未添加到版本库
[root@getlab-node1 xiaoding]# git add README.md
[root@getlab-node1 xiaoding]# git status -s
A README.md #A 已添加到暂存区
[root@getlab-node1 xiaoding]#
提交暂存区的数据:
[root@getlab-node1 xiaoding]# git commit -m "add README.md"
[master (root-commit) 52a1911] add README.md
1 file changed, 1 insertion(+)
create mode 100644 README.md
[root@getlab-node1 xiaoding]# git status -s #无任何显示,标识已经提交到版本库
[root@getlab-node1 xiaoding]#
再次修改:
[root@getlab-node1 xiaoding]# vim README.md
xiaoding
xiaoding
[root@getlab-node1 xiaoding]# git status -s
M README.md #右M 表示文件在工作区被修改
[root@getlab-node1 xiaoding]#
撤销修改:
[root@getlab-node1 xiaoding]# git checkout -- README.md
[root@getlab-node1 xiaoding]# cat README.md
xiaoding
[root@getlab-node1 xiaoding]#
重新修改:
[root@getlab-node1 xiaoding]# echo timinglee> README.md
[root@getlab-node1 xiaoding]# git add README.md
[root@getlab-node1 xiaoding]# git statrus -s
git: 'statrus' is not a git command. See 'git --help'.
The most similar command is
status
[root@getlab-node1 xiaoding]# git status -s
M README.md #左M表示文件已经在版本库中并被跟踪,
[root@getlab-node1 xiaoding]#
从暂存区撤销:
[root@getlab-node1 xiaoding]# git restore --staged README.md
[root@getlab-node1 xiaoding]# git status -s
M README.md
[root@getlab-node1 xiaoding]#
重新提交:
[root@getlab-node1 xiaoding]# git add README.md
[root@getlab-node1 xiaoding]# git status -s
M README.md
[root@getlab-node1 xiaoding]#
更新文件:
[root@getlab-node1 xiaoding]# echo timingding >> README.md
[root@getlab-node1 xiaoding]# git add README.md
[root@getlab-node1 xiaoding]# echo timingding >> README.md
[root@getlab-node1 xiaoding]# git status -s
MM README.md #MM表示有一部分在暂存区,还有一部分没有提交
[root@getlab-node1 xiaoding]#
如果现在提交只能提交在暂存区中的部分:
[root@getlab-node1 xiaoding]# git commit -m "update v2"
[master 5b49e73] update v2
1 file changed, 2 insertions(+), 1 deletion(-)
[root@getlab-node1 xiaoding]# git status -s
M README.md #右M还在
[root@getlab-node1 xiaoding]#
查看已暂存和未暂存的修改变化:
[root@getlab-node1 xiaoding]# echo timingding >> README.md
[root@getlab-node1 xiaoding]# git diff
diff --git a/README.md b/README.md
index 065bdae..e683b61 100644

[root@getlab-node1 xiaoding]#
跳过使用暂存区,只能在提交过的在版本库中存在的文件使用如果文件状态是"??"不能用此方法:
[root@getlab-node1 xiaoding]# git commit -a -m "update v3"
[master ab608f4] update v3

[root@CICD-node1 xiaoding]# git checkout -- ding.txt
[root@CICD-node1 xiaoding]# ls

从版本库中删除文件:
[root@getlab-node1 xiaoding]# git rm ding.txt
rm 'ding.txt'
[root@getlab-node1 xiaoding]# git status -s

2.3.3.2 git对于文件如何忽略
在做软件开发时对源码编译会产生一些临时文件,我们在提交时需要忽略这些临时文件
[root@getlab-node1 xiaoding]# mkdir dir1/
[root@getlab-node1 xiaoding]# touch dir1/.file2
[root@getlab-node1 xiaoding]# git status -s
?? dir1/
[root@getlab-node1 xiaoding]#
[root@getlab-node1 xiaoding]# echo .file1 > .gitignore
[root@getlab-node1 xiaoding]# git status -s
?? .gitignore
?? dir1/
[root@getlab-node1 xiaoding]#
[root@getlab-node1 xiaoding]# echo ".*" > .gitignore
[root@getlab-node1 xiaoding]# git status -s
[root@getlab-node1 xiaoding]#
三、gitlab代码仓库
3.1 gitlab简介
-
GitLab 是一个用于仓库管理系统的开源项目,使用 Git 作为代码管理工具,并在此基础上搭建起来的 web 服务。
-
GitLab 具有很多功能,比如代码托管、持续集成和持续部署(CI/CD)、问题跟踪、合并请求管理等。它可以帮助开发团队更好地协作开发软件项目,提高开发效率和代码质量。

3.2 gitlab 的部署实施
3.2.1 部署gitlab
部署gitlab需要内存大于4G
[root@getlab-node1 ~]# yum install -y curl policycoreutils-python openssh-server perl
[root@getlab-node1 ~]# dnf install gitlab-ce-17.1.6-ce.0.el9.x86_64.rpm
3.2.2 配置gitlab
修改配置文件:
[root@getlab-node1 ~]# cd /etc/gitlab/
[root@getlab-node1 gitlab]# ls
gitlab.rb
[root@getlab-node1 gitlab]# vim gitlab.rb
32 external_url 'http://172.25.254.50'
修改配置文件后需利用gitlab-crt来生效:
[root@getlab-node1 ~]# gitlab-ctl reconfigure
3.2.3 登陆gitlab
用户名默认为 root
。如果在安装过程中指定了初始密码,则用初始密码登录,如果未指定密码,则系统会随机生成一个密码并存储在 /etc/gitlab/initial_root_password
文件中, 查看随机密码并使用 root
用户名登录。
注意:出于安全原因,24 小时后,/etc/gitlab/initial_root_password
会被第一次 gitlab-ctl reconfigure
自动删除,因此若使用随机密码登录,建议安装成功初始登录成功之后,立即修改初始密码。
原始密码:
[root@getlab-node1 gitlab]# 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: EjhFCCHKf6M8GNd7BlN2CFmmVO+OBp0k1rVbDSADII0=
# NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.

四、Jenkins
4.1 Jenkins简介
-
Jenkins是开源CI&CD软件领导者, 提供超过1000个插件来支持构建、部署、自动化, 满足任何项目的需要。
-
Jenkins用Java语言编写,可在Tomcat等流行的servlet容器中运行,也可独立运行
CI(Continuous integration持续集成)持续集成强调开发人员提交了新代码之后,立刻进行构建、(单元)测试。
CD(Continuous Delivery持续交付) 是在持续集成的基础上,将集成后的代码部署到更贴近真实运行环境(类生产环境)中
4.2 部署Jenkins

添加完成后报错依然存在,因为ssh首次连接主机是需要签名认证,需要手动输入yes
还有两太主机之间一定要做好解析
可以在这里连接输入yes:
不想输入yes,可以修改配置:
[root@jenkins-node1 .ssh]# vim /etc/ssh/ssh_config
Host *
StrictHostKeyChecking no
# ForwardX11 no
# PasswordAuthentication yes
# HostbasedAuthentication no
[root@jenkins-node1 .ssh]# ssh -l root 172.25.254.50
