第一个mysql自动备份脚本。

#!/bin/bash

#auto backup mysql database for test

#by hag

backCMD=/usr/bin/mysqldump

dbuser=root

dbpasswd=admin123

databasename=test

backup_dir=/opt/backup/mysql

if [ ! -d $backup_dir ]; then

    mkdir -p $backup_dir

fi

if [ $UID -ne 0 ]; then

  echo "must be root can  run the script!"

fi

$backCMD -u$dbuser -p$dbpasswd $databasename > $backup_dir/nimeide.sql

if [ $? -eq 0 ]; then

 echo " this backup mysql successfully!"

  else

  echo " this backup mysql failed!"

fi
