Jenkins 是什么？

Jenkins 是一个可扩展的持续集成引擎。

主要用于：

持续、自动地构建/测试软件项目。
监控一些定时执行的任务。

Jenkins 拥有的特性包括：

易于安装-只要把jenkins.war部署到servlet容器，不需要数据库支持。
易于配置-所有配置都是通过其提供的web界面实现。
集成RSS/E-mail通过RSS发布构建结果或当构建完成时通过e-mail通知。
生成JUnit/TestNG测试报告。
分布式构建支持Jenkins能够让多台计算机一起构建/测试。
文件识别:Jenkins能够跟踪哪次构建生成哪些jar，哪次构建使用哪个版本的jar等。
插件支持:支持扩展插件，你可以开发适合自己团队使用的工具。

准备工作

环境

JDK:1.8  
Jenkins:2.83
Centos:7.3

安装

下载

cd /opt
wget http://mirrors.jenkins.io/war/2.83/jenkins.war

启动

关闭防护墙

systemctl stop firewalld.service

启动服务

java -jar jenkins.war

Jenkins 就启动成功了！它的war包自带Jetty服务器

访问

浏览器访问：http://localhost:8080/

第一次启动Jenkins时，出于安全考虑，Jenkins会自动生成一个随机的按照口令。

注意控制台输出的口令，复制下来，然后在浏览器输入密码：

*************************************************************
Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:

84a2f219030f45568c89e6602af60877 

This may also be found at: /root/.jenkins/secrets/initialAdminPassword

*************************************************************

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:

接下来是进入插件安装进度界面:

配置用户名密码:

初始化成功后进入 Jenkins 首页:

全局工具配置.Jdk,Mavem,git Docker,等配置，安装

构建项目

新建项目

这里，选择构建一个自由风格的软件项目；

源码管理

Jenkins支持多种源码管理服务器；

构建配置

选择 Execute shell 构建 输入一下命令并且保存

mvn clean package

部署脚本

把脚本放到 /etc/rc.d/init.d 下赋权限 chmod 777 spring-boot.sh

#!/bin/bash

SpringBoot=$2

if [ "$1" = "" ];
then
    echo -e "\033[0;31m 未输入操作名 \033[0m  \033[0;34m {start|stop|restart|status} \033[0m"
    exit 1
fi

if [ "$SpringBoot" = "" ];
then
    echo -e "\033[0;31m 未输入应用名 \033[0m"
    exit 1
fi

function start()
{
    count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`
    if [ $count != 0 ];then
        echo "$SpringBoot is running..."
    else
        echo "Start $SpringBoot success..."
        BUILD_ID=dontKillMe nohup java -jar $SpringBoot > /dev/null 2>&1 &
    fi
}

function stop()
{
    echo "Stop $SpringBoot"
    boot_id=`ps -ef |grep java|grep $SpringBoot|grep -v grep|awk '{print $2}'`
    count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`

    if [ $count != 0 ];then
        kill $boot_id
        count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`

        boot_id=`ps -ef |grep java|grep $SpringBoot|grep -v grep|awk '{print $2}'`
        kill -9 $boot_id
    fi
}

function restart()
{
    stop
    sleep 2
    start
}

function status()
{
    count=`ps -ef |grep java|grep $SpringBoot|grep -v grep|wc -l`
    if [ $count != 0 ];then
        echo "$SpringBoot is running..."
    else
        echo "$SpringBoot is not running..."
    fi
}

case $1 in
    start)
    start;;
    stop)
    stop;;

部署语法

mvn clean package

cp /etc/rc.d/init.d/spring-boot.sh /root/.jenkins/workspace/file-manager/target

cd /root/.jenkins/workspace/file-manager/target

./spring-boot.sh restart file-manager-1.0-SNAPSHOT.jar

请注意配置构建脚本的时候的写法,没有BUILD_ID=dontKillMe 是不可以的

BUILD_ID=dontKillMe nohup java -jar $SpringBoot > /dev/null 2>&1 &
