编写简单的.gitlab-ci.yml打包部署项目

服务器说明：

192.168.192.120：项目服务器

192.168.192.121：GitLab

为了可以使用gitlab的cicd功能，我们需要先安装GitLab Runner

安装GitLab Runner参考：

GitLab实现CICD自动化部署_gitlab cidi_程序员xiaoQ的博客-CSDN博客

手动在 GNU/Linux 上安装极狐GitLab Runner | 极狐GitLab
 

安装好GitLab Runner，我们主要编写.gitlab-ci.yml

在GitLab管理员界面，找到Settings -> CI/CD -> Variables，添加STAGING_PRIVATE_KEY变量

需要在192.168.192.120服务器执行ssh-keygen生成密钥对，其中STAGING_PRIVATE_KEY的值为私钥

在192.168.192.120服务器执行下面操作：

1.ssh-keygen，不要输入密码，直接回车

2.cat ~/.ssh/id_rsa，复制私钥到STAGING_PRIVATE_KEY

3.cd /root/.ssh/ && cat id_rsa.pub >> authorized_keys， 把 ssh 公钥添加到认证授权文件，这样可以不需要输入密码

 .gitlab-ci.yml内容：

# This file is a template, and might need editing before it works on your project.
# This is a sample GitLab CI/CD configuration file that should run without any modifications.
# It demonstrates a basic 3 stage CI/CD pipeline. Instead of real tests or scripts,
# it uses echo commands to simulate the pipeline execution.
#
# A pipeline is composed of independent jobs that run scripts, grouped into stages.
# Stages run in sequential order, but jobs within stages run in parallel.
#
# For more information, see: https://docs.gitlab.com/ee/ci/yaml/index.html#stages
#
# You can copy and paste this template into a new `.gitlab-ci.yml` file.
# You should not add this template to an existing `.gitlab-ci.yml` file by using the `include:` keyword.
#
# To contribute improvements to CI/CD templates, please follow the Development guide at:
# https://docs.gitlab.com/ee/development/cicd/templates.html
# This specific template is located at:

部分说明：# 不存在ssh-agent就下载安装
'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'# ssh-agent是一个密钥管理器，运行ssh-agent以后，使用ssh-add将私钥交给ssh-agent保管，其他程序需要身份验证的时候可以将验证申请交给ssh-agent来完成整个认证过程
eval $(ssh-agent -s)# ssh-add命令是把专用密钥添加到ssh-agent的高速缓存中,从而提高ssh的认证速度
ssh-add <(echo "$STAGING_PRIVATE_KEY")# scp -o StrictHostKeyChecking=no，ssh -o StrictHostKeyChecking=no中的
StrictHostKeyChecking=no去掉对主机的验证检查
scp -o StrictHostKeyChecking=no project.tar root@192.168.192.120:/root/gitlab/
ssh -o StrictHostKeyChecking=no root@192.168.192.120# 在192.168.192.120服务器执行以下命令
cd /root/gitlab && 
tar -xf project.tar && 
pwd && 
ls && 
echo 'exit' && 
exit
