jenkins部署java項目在本地(三)


(1)新建maven構建的java項目

pom.xml的配置

(2)新建jenkins項目,開始配置

(3)前面就是配置項目的描述,以及源碼關聯 和以往的配置一樣

(4)在Pre-step這一欄配置中 選擇 execute shell

(5)在execute shell 框框中填寫腳本命令 (也可以把腳本命令寫在本機某個位置,然后執行該腳本 比如 把命令都放到 /home/start.sh 文件中 ,然后再在腳本中就寫 sh /home/start.sh)

(6)腳本命令詳解 (#代表注釋內容,第一行不屬於注釋,不能省略)

#!/bin/bash
cd /usr/local/tool/jenkins_program/jenkins_jar #進入指定目錄
#得到進程ID pid,kill該進程
pid=`cat /usr/local/tool/jenkins_program/jenkins_jar/pid` #得到/usr/local/tool/jenkins_program/jenkins_jar/目錄下 pid文件中的內容
if [ -n "$pid" ]  
then
   echo "kill -9 的pid:" $pid
   kill -9 $pid    #kill進程ID為 pid 的進程
fi

#將要執行的jar 復制到指定目錄下  (這里可以不用寫,如果寫的話   /usr/lib/jenkins/workspace/jenkins_jar/target/jenkins_jar.jar 是你jenkins中工作區間中你的項目的jar包存放位置

/usr/local/tool/jenkins_program/jenkins_jar 是你的目標執行該jar的位置,如果你打算直接在工作區間目錄下執行,這個可以省略不寫)
cp /usr/lib/jenkins/workspace/jenkins_jar/target/jenkins_jar.jar  /usr/local/tool/jenkins_program/jenkins_jar

#執行jar,並將進程掛起,保存進程ID到 pid文件
echo "Execute shell Finish"
BUILD_ID=dontKillMe nohup java -jar /usr/lib/jenkins/workspace/jenkins_jar/target/jenkins_jar.jar  &
echo "$!" > pid #得到剛剛啟動的進程id,寫到/usr/local/tool/jenkins_program/jenkins_jar目錄下的pid文件中,這就是上面cd語句的作用

BUILD_ID=dontKillMe :防止殺死剛剛啟動的進程

nohup java -jar /usr/lib/jenkins/workspace/jenkins_jar/target/jenkins_jar.jar  &   #執行項目jar包,將進程啟動並且掛起

(7)配置完后可以執行構建了,結果會直接在Console Output輸出
