先安装jdk、maven、git必需环境

一、安装maven

1.下载

wget https://archive.apache.org/dist/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

2.下载下来之后解压，并在/etc/profile中添加mave环境

export MAVEN_HOME=/usr/local/maven
    export PATH=$PATH:$MAVEN_HOME/bin

3.生效

source /etc/profile

4.查看

mvn -verison

二、git安装

yum -y install git

git config --global user.name "test"

git config --global user.email "test@ll.com.cn"

三、安装jenkins

1.下载

wget  http://mirrors.jenkins.io/war-stable/2.263.1/jenkins.war

2. 在下载jenkins.war的目录下，启动，并将端口号改掉

nohup java -Xms256m -Xmx256m -jar jenkins.war --httpPort=8089  > ./jenkins.log 2>&1 &

3.在启动的时候，日志中会打印出来初始密码，也可以

cat /root/.jenkins/secrets/initialAdminPassword

4.在浏览器中输入 ip:端口号  访问页面，会让输入上一步的密码

5.进入用户自定义插件页面，建议选择安装官方推荐插件

6.插件安装完成之后，继续配置用户名密码

四、jenkins配置

进入  系统管理--全局工具配置

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lhbnlmMjAxNg_size_16_color_FFFFFF_t_70 4][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lhbnlmMjAxNg_size_16_color_FFFFFF_t_70 5][]

五、项目部署

1.新建任务

2.项目配置

2.1丢弃旧的构建

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lhbnlmMjAxNg_size_16_color_FFFFFF_t_70 7][]

2.2源码管理

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lhbnlmMjAxNg_size_16_color_FFFFFF_t_70 8][]

2.3构建环境

2.4build    clean install -Dmaven.test.skip=true

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lhbnlmMjAxNg_size_16_color_FFFFFF_t_70 10][]

2.5 点击Add post-build step，选择 Excute Shell

在此处加入自己项目的脚本，（如果是cloud项目，多复制几个修改一下即可）例如：

#!/bin/sh
    export EUREKA=eureka.jar
    
    export EUREKA_port=8761
    
    export dir=/root/.jenkins/workspace/project
    
    	## BEGIN--EUREKA-----------------------------------------------------------------------------------------------------------------
    	P_ID=`ps -ef | grep -w $EUREKA_port | grep -v "grep" | awk '{print $2}'`
    	if [ "$P_ID" == "" ]; then
    		echo "===EUREKA process not exists or stop success"
    	else
    		kill -9 $P_ID
    		echo "EUREKA killed success"
    	fi
    
    	echo "===EUREKAR stop success==="
    	## 启动EUREKA
    	echo "--------启动EUREKA start--------------"
        BUILD_ID=DONTKILLME
    	
    	nohup java -Xms128m -Xmx128m -jar $dir/eureka/target/$EUREKA --server.port=$EUREKA_port  > $dir/eureka.log 2>&1 &
    	
    	EUREKA_pid=`lsof -i:$EUREKA_port|grep "LISTEN"|awk '{print $2}'`
    	until [ -n "$EUREKA_pid" ]
    		do
    		  EUREKA_pid=`lsof -i:$EUREKA_port|grep "LISTEN"|awk '{print $2}'`  
    		done
    	echo "EUREKA pid is $EUREKA_pid" 
    	echo "--------EUREKA start success--------------"
    	## END--EUREKA---------------------------------------------------------------------------------------------------------------------

2.6保存之后，就可以构建项目了

六、配置jenkins开机自启

vi jenkins.sh

# !/bin/bash
    
    pid=`ps -ef | grep jenkins.war | grep -v 'grep'| awk '{print $2}'| wc -l`
    
      if [ "$1" = "start" ];then
      if [ $pid -gt 0 ];then
      echo 'jenkins is running...'
    else
       nohup /usr/local/jdk/jdk8/bin/java -Xms256m -Xmx256m  -jar /usr/local/jenkins/jenkins.war --httpPort=8096 > /usr/local/jenkins/jenkins.log  2>&1 &
       echo 'jenkins is started...'
    
      fi
      elif [ "$1" = "stop" ];then
      exec ps -ef | grep jenkins | grep -v grep | awk '{print $2}'| xargs kill -9
      echo 'jenkins is stop..'
    else
      echo "Please input like this:"/usr/local/jenkins/jenkins.sh start" or "/usr/local/jenkins/jenkins.sh stop""
      fi

chmod +x  jenkins.sh

### 在/etc/rc.d/rc.local文件底部，添加内容： ###

# jenkins              
     /usr/local/jenkins/jenkins.sh start
