MySQL备份时排除指定数据库的方法

#!/bin/bash
# Description: backup mysql data
# Author: lee
FILE="mysql_`date +%F`"
BACKDIR="/mysqlbackup"
CONF_FILE="/etc/my.cnf"
mysql -uroot -e 'show databases'|egrep -v "Database|information_schema|performance_schema" \ |xargs mysqldump -uroot --databases > $BACKDIR/$FILE.sql && cp $CONF_FILE $BACKDIR/$FILE.cnf \
&& echo -e "Machine: Oracle\nIP: 172.16.10.12\nStatus: MySQL is backup complete" | \ mail -s "MySQL BackUP Complete" lee@126.com

#!/bin/sh
for j in `mysql -uroot -e "USE spservice;SHOW TABLES" | grep -v Tables`
do
  case $j in
    mo_log|mt_log|report_info)
      :
      ;;
    *)
    mysqldump -uroot --default-character-set=gbk --opt spservice $j >> $j.sql
  esac
done
>>表名不固定 #!/bin/sh
for j in `mysql -uroot -e "USE spservice;SHOW TABLES" | grep -v Tables`
do
  for i in "$@"
  do
    if [ $j != $i ];then
      mysqldump -uroot --default-character-set=gbk --opt spservice $j >> $j.sql
    fi
  done
done
>>更简洁的方法
#!/bin/sh
for j in `mysql -uroot -e "USE spservice;SHOW TABLES" | grep -v Tables`
do
  echo $@ | grep -wq "\<$j\>"
  if [ $? -ne 0 ];then
    mysqldump -uroot --default-character-set=gbk --opt spservice $j >> $j.sql
  fi
done
>>使用方法
sh exclude.sh mo_log mt_log report_log
#定义一个shell数组
tables=(mo_log mt_log report_log)
sh exclude.sh ${tables[@]}
