mysql备份监控脚本

建一系列目录用于监控和备份

su - mysql

cd /mysql_backup

mkdir backup.1 backup.2 backup.3 monitor_log scripts

定时备份

#!/bin/sh
db_user="user"
db_passwd="password"
db_host="localhost"
backup_dir="/mysql_backup/master_backup"
time="$(date +"%Y-%m-%d-%H-%M")"
# mysql, mysqldump and some other bin's path
MYSQL="/usr/local/mysql/bin/mysql"
MYSQLDUMP="/usr/local/mysql/bin/mysqldump"
MKDIR="/bin/mkdir"
RM="/bin/rm"
MV="/bin/mv"
GZIP="/bin/gzip"
# check the directory for store backup is writeable
test ! -w $backup_dir && echo "Error: $backup_dir is un-writeable." && exit 0
# the directory for story the newest backup
test ! -d "$backup_dir/backup.0/" && $MKDIR "$backup_dir/backup.0/"
# get all databases
#all_db="$($MYSQL -u $db_user -h $db_host -p$db_passwd -Bse 'show databases')"
#for db in $all_db
#do
#$MYSQLDUMP -u $db_user -h $db_host -p$db_passwd --skip-lock-tables --single-transaction $db | $GZIP -9 > "$backup_dir/backup.0/$time.$db.gz"
#done

$MYSQLDUMP -u$db_user -p$db_passwd --all-databases --opt --add-drop-database --add-drop-table --events --triggers --routines --default-character-set=utf8 --master-data=2 --single-transaction --complete-insert --quote-names --log-error=$backup_dir/mysqldump$time.log | $GZIP -9 > "$backup_dir/backup.0/$time.all_mysql.gz"

循环删除

#!/bin/sh
backup_dir="/mysql_backup/master_backup"
time="$(date +"%Y-%m-%d-%H-%M")"
MKDIR="/bin/mkdir"
RM="/bin/rm"
MV="/bin/mv"

test ! -d "$backup_dir/backup.0/" && $MKDIR "$backup_dir/backup.0/"
# delete the oldest backup
test -d "$backup_dir/backup.3/" && $RM -rf "$backup_dir/backup.3"
# rotate backup directory
for int in 2 1 0
do
if(test -d "$backup_dir"/backup."$int")
then
next_int=`expr $int + 1`
$MV "$backup_dir"/backup."$int" "$backup_dir"/backup."$next_int"
fi
done
exit 0;
