mysqldump中怎么備份MYSQL數據庫

這篇文章將為大家詳細講解有關mysqldump中怎么備份MYSQL數據庫，文章內容質量較高，因此小編分享給大家做個參考，希望大家閱讀完這篇文章后對相關知識有一定的了解。

 
1、備份腳本內容

[david_yeung@localhost ~]$ cat fast_backup
#!/bin/sh
#
# Created by david yeung.
#
# 20080707.
#
# Backup 's full data.
#
DBNAME=$1
BACKUPDIR=/home/david_yeung/backup_new
USERNAME=backup_user
PASSWD=123456
TARNAME="$BACKUPDIR"/backup"$1"`date '+%Y%m%d'`
# Add your own database name here.
case "$1" in
  my_site);;
  *) exit;;
esac
# Get all the tables' name.
NUM=`/usr/local/mysql/bin/mysql -u$USERNAME -p$PASSWD -s -vv -e "show tables" -D $DBNAME|wc -l`
HEADNUM=`expr ${NUM} - 3`
TAILNUM=`expr ${NUM} - 7`
ARR1=`/usr/local/mysql/bin/mysql -u$USERNAME -p$PASSWD -s -vv -e "show tables" -D $DBNAME| head -n"$HEADNUM" | tail -n "$TAILNUM"`
ARR2=($ARR1)
i=0
while [ "$i" -lt "${#ARR2[@]}" ]
do
 tmpFileName=${ARR2[$i]}
 # The real dump process.
 /usr/local/mysql/bin/mysqldump -u$USERNAME -p"$PASSWD" "$DBNAME" "$tmpFileName" >> "$TARNAME"
 let "i++"
done

2、因為我們一直用存儲過程，所以得單獨備份出來。

[david_yeung@localhost ~]$ cat fast_sp
#!/bin/sh
# Created by david yeung 20080122.
#
# Backup site's routine.
TARNAME=/home/david_yeung/backup_new/spBackup"$1"`date '+%Y%m%d'`
/usr/local/mysql/bin/mysqldump -ubackup_user -p123456 -n -t -d -R my_site > "$TARNAME"
 
3、丟到計劃任務里面去，就不管了。

[root@localhost backup_new]# crontab -l
0 01 * * * /home/david_yeung/fast_backup my_site
0 0 * * 5 /home/david_yeung/fast_sp
