# **前提工作** #

## 1、创建opt目录(所有东西安装在此) ##

cd /
    mkdir /opt  #jdk maven安装目录
    mkdir /opt/jar/helloworld  #jar shell脚本目录

## 2、获取安装包（Jenkins+JDK+Maven+shell脚本） ##

### 2.1安装JDK ###

cd /opt
    #解压
    tar -zxvf  jdk-8u131-linux-x64.tar.gz
    #修改配置
    vim /etc/profile

配置环境变量

#jdk
    export JAVA_HOME=/opt/jdk1.8.0_131
    export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
    export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin

### 2.2安装Maven ###

cd /opt
    tar -zxvf  apache-maven-3.6.1-bin.tar.gz
    vim /etc/profile

配置环境变量

#maven
    export MAVEN_HOME=/opt/apache-maven-3.6.1
    export PATH=${PATH}:${MAVEN_HOME}/bin

### 2.3安装Git ###

sudo apt-get install git # 安装git
    
    git config --global user.name "evio"
    
    git config --global user.email "977905698@qq.com"

# 二、项目准备 #

## 1、gitee创建新仓库 ##

## 2.创建SpringBoot项目 ##

拉取代码创建Springboot项目

## 三、准备脚本（脚本存放目录 cd  /opt/jar/helloworld） ##

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 4][]

## 3.1.stop.sh ##

echo "Stopping SpringBoot Application"
    pid=`ps -ef | grep  helloworld-0.0.1-SNAPSHOT.jar  | grep -v grep | awk '{print $2}'`
    if [ -n "$pid" ]
    then
       kill -9 $pid
    fi

## 3.1.bak.sh ##

#备份文件目录
    bakfile="/opt/jar/helloworld/helloworld-0.0.1-SNAPSHOT.jar"
    #备份1和备份2目录是否存在
    if test -e $file1
    then
        echo '========================'    
    else
        echo '===备份1目录不存在，创建目录==='
            mkdir -p $file1
    fi
    if test -e $file2
    then
        echo '========================'
    else
        echo '===备份2目录不存在,创建目录==='
            mkdir -p $file2
    fi
    
    
    
    #获取备份1和备份2的文件个数
    filecount1=`ls $file1 | wc -w`
    filecount2=`ls $file2 | wc -w`
    
    #如果备份1文件数小于5  存入备份1
    if  [ $filecount1 -lt 5 ]
    then
    	echo " =====备份1副本个数: $filecount1 ==  备份2副本个数: $filecount2===== "
    	echo " =====正写入备份1===== "
    	mv   $bakfile  $file1/${bakfile##*/}.`date +%Y%m%d%H%M%S`
    	echo " ======备份完毕====== "
    fi
    
    #如果备份1等于5  备份2小于5 存入备份2
    if  [ $filecount1 -eq 5 -a  $filecount2 -lt 5 ]
    then
    	echo " =====备份1副本个数: $filecount1 ==  备份2副本个数: $filecount2===== "
    	echo " 正写入备份2 "
    	 mv    $bakfile  $file2/${bakfile##*/}.`date +%Y%m%d%H%M%S`
    	echo "=====备份完毕===== "
    fi
    
    #如果备份1等于5  备份2等于5 清空备份2 备份1 存入备份2 清空备份1 存入备份1
    if  [ $filecount1 -eq 5 -a  $filecount2 -eq 5 ]
    then
    	echo " =====备份1副本个数: $filecount1 ==  备份2副本个数: $filecount2===== "
    	echo " =====正写入备份1===== "
    	#清空备份2
    	rm  -rf $file2/*

     	mv   $bakfile  $file1/${bakfile##*/}.`date +%Y%m%d%H%M%S`
    	echo " =====备份完毕===== "
    fi

## 3.3.replace.sh ##

mv /var/lib/jenkins/workspace/helloworld/hive/target/helloworld-0.0.1-SNAPSHOT.jar    /opt/jar/helloworld

## 四、配置Jenkins ##

### 4.1安装Jenkins ###

sudo rpm -ih jenkins-2.176.2-1.1.noarch.rpm
    
    
    
    自动安装完成之后： 
    
    /usr/lib/jenkins/jenkins.war    WAR包 
    
    /etc/sysconfig/jenkins       配置文件
    
    /var/lib/jenkins/        默认的JENKINS_HOME目录
    
    /var/log/jenkins/jenkins.log    Jenkins日志文件

在jenkins配置文件中配置 需要“vi /etc/init.d/jenkins”，把java路径加上，如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 5][]

启动命令

sudo service jenkins start

启动正常，可以访问：http://localhost:8080

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 6][]

指定目录查询登录密码

进入用户自定义插件界面，建议选择安装官方推荐插件，因为安装后自己也得安装:

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 7][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 8][]

等待一段时间之后，插件安装完成，配置用户名密码:

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 9][]

###  4.2配置Jenkins ###

进入 系统管理-》全局工具配置

**1、设置 jdk（前面安装的java，但是显示不在 jenkins 里的错误，所以这里再手动安装）**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 10][]

**2、设置 Git**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 11][]

**3、设置 Maven**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 12][]

**4、安装 [Maven Integration plugin][] 插件**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 13][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 14][]

## 五、部署项目 ##

**1、首页点击新建：输入项目名称**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 15][]

下方选择构建一个maven项目，点击确定。

勾选**丢弃旧的构建**，选择是否备份被替换的旧包。我这里选择备份最近的5个

如果你没有第二个选项，需要安装 [Maven Integration plugin][] 插件

2、勾选丢弃旧的构建，选择是否备份被替换的旧包。我这里选择备份最近的5个

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 16][]

3、源码管理，配置Git相关信息

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 17][]

4、构建环境中勾选“Add timestamps to the Console Output”，代码构建的过程中会将日志打印出来

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 18][]

5、在Build中输入打包前的mvn命令，如：

clean install -Dmaven.test.skip=true -Ptest

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 19][]

6、Post Steps 选择 Run only if build succeeds  点击Add post-build step，选择 Excute Shell

cd /opt/jar/helloworld/
    sh stop.sh
    sh bak.sh
    sh replace.sh
    BUILD_ID=dontKillMe nohup java -jar /opt/jar/helloworld/helloworld-0.0.1-SNAPSHOT.jar &

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMwOTA0OTg1_size_16_color_FFFFFF_t_70 20][]

![20190725213345683.png][]
