数据库备份的脚本，记录下，还需优化下

由于公司数据比较重要，隔一段时间就需要备份，就写了个简单的shell来维护下。。。

#!/bin/bash

#backup database

if [ $# -ge 1 ] ; then

  databaselist=$@

else

  databaselist="dodo_account dodo_edu"

fi

 

for database in $databaselist

do

if [ ! -e /home/guimingming/backup_databases/$database ]

then 

   mkdir -p /home/guimingming/backup_databases/$database

fi

 

mysqldump --opt -hxx.xx.xx.x -u{username} -p{pwd} $database |gzip > /home/guimingming/backup_databases/$database/$database$(date +"%Y-%m-%d %H:%M:%S").sql.gz

if [ $? -eq 0 ]

then

   echo "$(date +"%Y-%m-%d %H:%M:%S") Database ---$database---  Backup Successfully Completed "

   find /home/guimingming/backup_databases/$database/ -name $database* -ctime +1 -exec rm -rf {} ;

else

    echo "$(date +"%Y-%m-%d %H:%M:%S") Database  ---$database---  Backup unsuccessfully,please check out the reason " 

fi

 

done

 

 

#!/bin/bash 

# 假设将database_name数据库名改为database_name_2_2016_06_28 

# MyISAM直接更改数据库目录下的文件即可  

mysql -uroot  -e 'create database if not exists database_name;' 

list_table=$(mysql -uroot -Nse "select table_name from information_schema.TABLES where TABLE_SCHEMA='database_name_2'")  

for table in $list_table 

do

mysql -uroot -e "rename table database_name_2.$table to database_name.$table" 

done

#mysql -u root database_name_2<database_name_220160628-frm
