案例3：Jenkins后端工程构建

Jenkins中创建HIS-BACKEND工程

#Maven打包参数：Maven执行打包操作时需要调用pom.xml文件，所以需要指定pom.xml文件位置
clean package -Dmaven.test.skip=true    #清理旧文件、跳过测试直接打包

测试HIS-BACKEND工程构建

#Jenkins主机确认HIS-BACKEND构建情况
[root@Jenkins ~]# ls /var/lib/jenkins/workspace/            #确认拉取HIS-BACKEND代码
HIS-BACKEND  HIS-FONTEND
[root@Jenkins ~]# ls /var/lib/jenkins/workspace/HIS-BACKEND/
HIS-api  HIS-common  HIS-demo  HIS-mbg  HIS-service  pom.xml
[root@Jenkins ~]# ls /var/lib/jenkins/workspace/HIS-BACKEND/HIS-api/

案例6：HIS项目全流程

清理Jenkins工作目录

#手工清理Jenkins工作目录
[root@Jenkins ~]# rm -rf /var/lib/jenkins/workspace/*
[root@Jenkins ~]# 

前端全流程

#更新HIS-FONTEND工程
    1、构建前清理/opt/his/web/下原有代码
    2、构建后自动解压fontend.tar.gz压缩包
    3、删除fontend.tar.gz压缩包
    
#构建前操作
rm -rf /opt/his/web/*       #清理旧版本文件

#构建后操作
cd /opt/his/web/            #切换到前端代码存放目录
tar -xf fontend.tar.gz      #解压fontend.tar.gz压缩包
rm -rf fontend.tar.gz       #清理fontend.tar.gz压缩包

后端全流程

#更新HIS-FONTEND工程
    1、构建前终止HIS后端jar进程
    2、清理/opt/his/目录下原有jar包
    3、发送jar后远程启动jar包
    
#构建前操作
jps | grep jar | awk '{print $1}' | xargs kill      #查找HIS后端jar包pid并杀死进程
rm -rf /opt/his/HIS-api-1.0-SNAPSHOT.jar            #清理旧版本jar包

#构建后操作
cd /opt/his/                                                    #切换到jar包目录
nohup java -jar HIS-api-1.0-SNAPSHOT.jar > ./his.log 2>&1 &     #后台启动jar包
