#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
