最近项目组在推行自动构建，在每次build完了之后，需要自动把文件部署到linux服务器上，因此根据项目的具体的情况，写了一个shell脚本，供自动构建工具来调用执行部署。
粗略的思路就是：停止系统-->备份现有的环境-->部署新build的文件-->修改需要修改的配置文件(如果需要)-->启动系统
大致脚本如下：
#!/bin/bash
DAY=`date +%Y-%m-%d-%H:%M:%S`
#the path for deleting the log and tmp
APP_MAIN_PATH=/data/yousystem/jboss-5.1.0.GA/server/default
#the key word for searching the process id
PID_MSG=yousystem/
#msg of the file which is running now,backup it.
APP_FILE_NAME1=yousystem.war
APP_FILE_PATH1=/data/yousystem/jboss-5.1.0.GA/server/default/deploy
#msg of the start file which is used to start the system
APP_START_FILE=app-run.sh
APP_START_PATH=/data/yousystem
#msg of the update file
BUILD_FILE_NAME1=yousystem.war
BUILD_FILE_PATH=/data/backup/autobuild/build_files_backup
#msg of the old files for backup
OLD_FILE_PATH=/data/backup/autobuild/old_files_backup
#path of the shell script log
SHELL_LOG_PATH=/data/backup/autobuild
