Jenkins一键打包部署SpringBoot应用（精简版）

今天药忘吃喽~ 2023-02-09 14:14 32阅读 0赞

## 1. 概述 ##

Jenkins是一个开源的、提供友好操作界面的持续集成(CI)工具，起源于Hudson，主要用于持续、自动的构建/测试软件项目、监控外部任务的运行。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。通常与版本管理工具(SCM)、构建工具结合使用。常用的版本控制工具有SVN、GIT，构建工具有Maven、Ant、Gradle。

## 2. 说明 ##

这里不赘述相关概念和原理，仅描述如何将你的springboot应用通过jenkins实现一键打包部署的关键步骤  
环境： centos7 + docker

## 3. 步骤 ##

### 3.1 准备springboot应用，pom中需要有打包插件的配置 ###

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

### 3.2 Linux安装maven ###

（也可以直接在jenkins里配置自动安装）

1.  下载
    
        cd /opt/software
        wget https://downloads.apache.org/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz
2.  解压
    
        tar -zxvf apache-maven-3.6.3-bin.tar.gz -C /opt/module/
3.  配置环境变量
    
        vim /etc/profile
    
    在末尾加入如下配置
    
        export M2_HOME=/opt/module/apache-maven-3.6.3
        export PATH=$PATH:$M2_HOME/bin
    
    刷新配置
    
        source /etc/profile
    
    验证
    
        mvn -v
    
    ![在这里插入图片描述][20200519114320789.png]
4.  设置国内镜像地址加速
    
        vim conf/settings.xml
    
    在mirrors标签内新增如下配置
    
        <mirror>
            <id>alimaven</id>
            <mirrorOf>central</mirrorOf>
            <name>aliyun maven</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
        </mirror>

### 3.3 基于Docker安装Jenkins ###

1.  下载镜像
    
        docker pull jenkins/jenkins:lts
2.  运行容器  
    如果要使用自定义安装的maven，这里一定需要做好maven安装路径映射和仓库路径映射
    
        docker run --privileged=true -v /root/jenkins_home:/var/jenkins_home -v /opt/module/apache-maven-3.6.3:/opt/module/apache-maven-3.6.3 -v /root/.m2/repository:/root/.m2/repository -p 8080:8080 -p 50000:5000 --name jenkins -u root  jenkins/jenkins:lts

3.  访问jenkins  
    http://ip:8080/  
    第一次比较慢，输入初始密码解锁jenkins
4.  因插件安装非常慢，先不要安装插件，执行以下命令修改下载的服务器地址为国内镜像
    
        sed -i 's/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' /root/jenkins_home/updates/default.json && sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' /root/jenkins_home/updates/default.json
5.  重启jenkins，并重新登录
    
        docker restart jenkins
6.  安装推荐插件
7.  创建第一个管理员用户
8.  实例配置，默认即可，此时jenkins进入就绪状态  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L20wXzM3NjEzNTAz_size_16_color_FFFFFF_t_70 1]  
    这里建议重启一次
9.  自定义插件安装  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L20wXzM3NjEzNTAz_size_16_color_FFFFFF_t_70 2]  
    选择插件：  
    ![在这里插入图片描述][20200519115250372.png]
10. maven配置  
    在Global Tool Configuration找到maven配置  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L20wXzM3NjEzNTAz_size_16_color_FFFFFF_t_70 3]
11. ssh配置  
    先配置root帐号密码  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L20wXzM3NjEzNTAz_size_16_color_FFFFFF_t_70 4]  
    在系统配置中配置ssh并测试  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L20wXzM3NjEzNTAz_size_16_color_FFFFFF_t_70 5]
12. 授权策略  
    这里配置从简![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L20wXzM3NjEzNTAz_size_16_color_FFFFFF_t_70 6]

### 3.4 将代码上传git ###

本文采用gitee

### 3.5 创建jenkins任务 ###

1.  新建任务

2.  设置git仓库地址及设置git帐号密码  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L20wXzM3NjEzNTAz_size_16_color_FFFFFF_t_70 8]  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L20wXzM3NjEzNTAz_size_16_color_FFFFFF_t_70 9]
3.  构建配置  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L20wXzM3NjEzNTAz_size_16_color_FFFFFF_t_70 10]  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L20wXzM3NjEzNTAz_size_16_color_FFFFFF_t_70 11]
4.  构建环境设置  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L20wXzM3NjEzNTAz_size_16_color_FFFFFF_t_70 12]  
    脚本参考
    
        cd /root/jenkins_home/workspace/jenkins-demo
        app_name='jenkins-demo'
        docker stop ${app_name}
        echo '----stop container----'
        docker rm ${app_name}
        echo '----rm container----'
        docker build -t jenkins-demo .
        docker run -d  TZ="Asia/Shanghai"  -p 8900:8800 --name ${app_name} jenkins-demo
        echo '----start container----'

### 3.6 创建dockerfile ###

可以提前在springboot项目根目录创建，内容参考

FROM java
    MAINTAINER dacai
    ADD ./target/jenkins-demo-1.0-SNAPSHOT.jar /app/app.jar
    ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app/app.jar"]

### 3.7 执行jenkins任务 ###
