## 1.安装环境依赖 ##

安装jdk、maven  
去官网下载  
[https://www.oracle.com/java/technologies/javase-downloads.html][https_www.oracle.com_java_technologies_javase-downloads.html]  
[https://maven.apache.org/][https_maven.apache.org]  
分别解压到相应的目录下

![在这里插入图片描述][b99efd6aa06b4fc99764cc0ba975ef39.png]  
java和maven安装完成后在/etc/profile文件里面配置下

vim /etc/profile

export JAVA_HOME=/usr/local/jdk/jdk1.8.0_301
    export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
    export JRE_HOME=$JAVA_HOME/jre
    export MAVEN_HOME=/usr/local/maven/apache-maven-3.8.2
    export PATH=$JAVA_HOME/bin:$MAVEN_HOME/bin:$PATH

然后使文件生效

source /etc/profile

安装git

yum install -y git

## 2.配置jenkins ##

Manage Jenkins - Global Tool Configuration

配置jdk路径

查看git路径  
![在这里插入图片描述][2854b35b871d40f5b1b580fa7fd111a4.png]  
配置git  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3JqMjAxNzIxMTgxMQ_size_16_color_FFFFFF_t_70 1]

配置maven  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3JqMjAxNzIxMTgxMQ_size_16_color_FFFFFF_t_70 2]

## 3.创建项目，提交到git ##

创建一个简单的springboot项目  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3JqMjAxNzIxMTgxMQ_size_16_color_FFFFFF_t_70 3]

然后编写Dockerfile

#使用哪个镜像构建
    FROM openjdk:8-jdk-alpine
    #容器内挂载路径
    VOLUME /tmp 
    #把当前路径下的jar包拷贝到容器内
    COPY ./target/demo-0.0.1-SNAPSHOT.jar jenkinsdemo.jar
    #运行命令
    ENTRYPOINT ["java","-jar","./jenkinsdemo.jar", "&"]

提交到git  
先github/gitee/gitlab 创建一个仓库 New Repository  
比如gitee  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3JqMjAxNzIxMTgxMQ_size_16_color_FFFFFF_t_70 4]

创建完成

然后切换到当前项目目录下

把当前项目初始化为一个git项目

git init

添加README.md

touch README.md

把当前项目下的所有文件添加到暂存区

git add .

提交到本地仓库

git commit -m "jenkinsdemo v1.0"

设置远程仓库地址

git remote add origin 你的git地址,如xxx.git

提交到远程仓库的master分支

git push -u origin master

## 4.New Item 新建项目 ##

添加执行脚本

#!/bin/bash
    #maven打包
    mvn clean package
    echo 'package ok!'
    echo 'build start!'
    cd ./
    service_name="jenkinsdemo"
    service_prot=8099
    #查看镜像id
    IID=$(docker images | grep "$service_name" | awk '{print $3}')
    echo "IID $IID"
    if [ -n "$IID" ]
    then
        echo "exist $SERVER_NAME image,IID=$IID"
        #删除镜像
        docker rmi -f $service_name
        echo "delete $SERVER_NAME image"
        #构建
        docker build -t $service_name .
        echo "build $SERVER_NAME image"
    else
        echo "no exist $SERVER_NAME image,build docker"
        #构建
        docker build -t $service_name .
        echo "build $SERVER_NAME image"
    fi
    #查看容器id
    CID=$(docker ps | grep "$SERVER_NAME" | awk '{print $1}')
    echo "CID $CID"
    if [ -n "$CID" ]
    then
        echo "exist $SERVER_NAME container,CID=$CID"
        #停止
        docker stop $service_name
        #删除容器
        docker rm $service_name
    else
        echo "no exist $SERVER_NAME container"
    fi
    #启动
    docker run -d --name $service_name --net=host -p $service_prot:$service_prot $service_name
    #查看启动日志
    #docker logs -f $service_name
