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
[email protected]
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 ---$database--- Backup Successfully Completed\r\n"
find /home/guimingming/backup_databases/$database/ -name $database\* -ctime +1 -exec rm -rf {} \;
else
echo "$(date +"%Y-%m-%d %H:%M:%S") Database ---$database--- Backup unsuccessfully,please check out the reason\r\n"
fi
done
#!/bin/bash
# 假设将database_name数据库名改为database_name_2_2016_06_28
# MyISAM直接更改数据库目录下的文件即可
mysql -uroot -e ‘create database if not exists database_name;‘
list_table=$(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
