linux+jenkins+github+.net core CI/CD 快速部署

目标：
代码提交后，在jenkins点击build，编译通过后能让linux更新.net core 文件和重新运行

步骤：

1.腾讯云搞一台免费linux服务器:https://cloud.tencent.com/
2.服务上安装jenkins https://www.jenkins.io/doc/book/installing/linux/#red-hat-centos
3.腾讯云防火墙开放8080端口， 另一台电脑访问jenkins地址http://{公网IP}:8080/
4.jenkins获取密码Unlock解锁，安装git和github插件,msbuild，创建Pipeline 加入脚本（文章最后）
5.github设置webhook http://{公网ip}:8080/github-webhook/ application/json
6.腾讯云防火墙开放5000端口 .net core 默认5000  注意配置服务为0.0.0.0:5000 不是localhost
7.linux 新建服务

7.1 sudo nano /etc/systemd/system/{service}.service
7.2 加入以下配置
[Unit]
Description={project} .NET Core 6.0 Web API
After=network.target

[Service]
WorkingDirectory=/opt/{project}
ExecStart=/usr/share/dotnet/dotnet /opt/{project}/{project}.dll
Restart=always
RestartSec=10
SyslogIdentifier={project}
User={你的linux用户名} 
Environment=ASPNETCORE_ENVIRONMENT=Production
Environment=ASPNETCORE_URLS=http://0.0.0.0:5000 # 添加这一行

[Install]
WantedBy=multi-user.target

7.3
sudo systemctl daemon-reload
sudo systemctl enable roadtodreams
sudo systemctl restart roadtodreams
sudo systemctl status roadtodreams

Pipeline脚本：

pipeline {
    agent any

    environment {
        DEPLOY_PATH = '/opt/{project}'  // 设置部署路径
        DOTNET_ROOT = '/usr/share/dotnet'
        PATH = "/usr/share/dotnet:$PATH"
        TARGET_FRAMEWORK = 'net6.0'  // 指定目标框架
        PROJECT_PATH = '{project}/{csproj}.csproj'  // 替换为你的项目路径
    }

    stages {
        stage('Checkout') {
            steps {
                // 检出代码
                git branch: 'main', url: 'https://github.com/{name}/{project}.git'
            }
        }

        stage('Build') {
            steps {
                script {
                    // 恢复依赖项
                    sh "dotnet restore ${PROJECT_PATH}"
                    // 构建项目
                    sh "dotnet build ${PROJECT_PATH} --configuration Release"
                    // 发布项目，指定目标框架
                    sh "dotnet publish ${PROJECT_PATH} --configuration Release --framework ${TARGET_FRAMEWORK} --output ./publish"
                }
            }
        }

        stage('Deploy') {
            steps {
                script {
                    // 确保部署目录存在
                    sh "sudo mkdir -p ${DEPLOY_PATH}"
                    // 将发布文件复制到部署路径
                    sh "sudo cp -r ./publish/* ${DEPLOY_PATH}"
                }
            }
        }

        stage('Run') {
            steps {
                script {
                    // 停止正在运行的实例（假设使用的是 systemd 服务）
                    sh "sudo systemctl stop {service}"
                    // 启动新实例
                    sh "sudo systemctl start {service}"
                    // 你可以添加检查服务状态的命令
                    sh "sudo systemctl status {service}"
                }
            }
        }
    }
}
