Linux 系统健康巡检脚本

客户应用系统服务器要做健康检查，操作系统为Red Hat Enterprise Linux 5.6，数据库为oracle 10g，写了如下shell脚本：

#!/bin/bash

echo "You are logged in as `whoami`";

if [ `whoami` != root ]; then

echo "Must be logged on as root to run this script."

exit

fi

CHECK_DATE=`date +%F`

echo "Running script at `date`"

CHECK_REPORT_PATH=/tmp/getinfo

ls -d $CHECK_REPORT_PATH

if [ $? -gt 0 ]

then

mkdir $CHECK_REPORT_PATH

fi

chmod -R 777 $CHECK_REPORT_PATH
