Mysql用戶在數(shù)據(jù)庫Mysql的表用戶中,為了備份這個(gè)表,你可以這樣做：

mysqldump -u root -p mysql user > UserTableBackup.sql

對于備份所有mysql數(shù)據(jù)庫并為每個(gè)數(shù)據(jù)庫創(chuàng)建一個(gè)文件,你可以自己編寫shell腳本,遵循一些可以幫助你的代碼：

# Get all database list first

DBS="$($MYSQL -u $MyUSER -h $MyHOST -p$MyPASS -Bse 'show databases')"

echo `date +%Y%m%d_%H_%M_%S` - Backup Mysql Database Started >> /home/Backup/Backup.log

for db in $DBS

do

skipdb=-1

if [ "$IGGY" != "" ];

then

for i in $IGGY

do

[ "$db" == "$i" ] && skipdb=1 || :

done

fi

if [ "$skipdb" == "-1" ] ; then

FILE="$MBD/$db.$HOST.$NOW.gz"

# do all inone job in pipe,

# connect to mysql using mysqldump for select mysql database

# and pipe it out to gz file in backup dir :)

echo `date +%Y%m%d_%H_%M_%S` - Backup "$db.$HOST.$NOW.gz" Started >> /home/Backup/Backup.log

$MYSQLDUMP -u $MyUSER -h $MyHOST -p$MyPASS --default-character-set=utf8 $db | $GZIP -9 > $FILE

echo `date +%Y%m%d_%H_%M_%S` - Backup "$db.$HOST.$NOW.gz" Completed ! >> /home/Backup/Backup.log

fi

done
