搭配Jenkins使用的服务器部署备份升级脚本

简介

主要搭配Jenkins使用，Jenkins将编译好的二进制文件上传至服务器指定文件夹中，然后执行该脚本进行原有程序备份并替换为新版程序。

参数说明

• backupList 需要备份的文件列表，使用的是shell中的数据，使用一个空格分割，不限制数量
• backupPath 需要备份的路径
• backupLimit 备份数量限制
• upgrageFilePath 新版本程序路径，一般为jenkins上传上来的临时路径

使用

• ./脚本名.sh B 备份
• ./脚本名.sh U 升级
• ./脚本名.sh BU 备份后升级
