mysqldump备份脚本一例

参考三思老师书中所写，感觉挺好用，记录下来，虽然是抄袭，但是手抄还是很累的,其中用到的其他脚本，在博客中已经记录：

mysql_full_backup.sh
#!/bin/sh
#Created by Clark 201710131716

source /data/mysqldata/scripts/mysql_env.ini

DATA_PATH=/data/mysqldata/backup/mysql_full
DATA_FILE=${DATA_PATH}/dbfullbak_`date +%F`.sql.gz
LOG_FILE=${DATA_PATH}/dbfullbak_`date +%F`.log
MYSQL_PATH=/usr/local/mysql/bin
MYSQL_DUMP="${MYSQL_PATH}/mysqldump -u${MYSQL_USER} -p${MYSQL_PASS} -S /data/mysqldata/${HOST_PORT}/mysql.sock -A -R -x --default-ch
aracter-set=utf8"

echo > $LOG_FILE
echo -e "=== Jobs started at `date +%F' '%T' '%w` ====\n" >>$LOG_FILE
${MYSQL_DUMP} | gzip > $DATA_FILE
echo -e "*** Excuted finshed at `date +%F' '%T' '%w`====" >>$LOG_FILE
echo -e "*** Backup file size: ` du -sh ${DATA_FILE}`====\n" >>$LOG_FILE

echo -e "---- Find expired backup and delete those files ----" >>${LOG_FILE}
for tfile in $(/bin/find $DATA_PATH/ -mtime +6)
do
                if [ -d $tfile ] ; then
                        rmdir $tfile
                elif [ -f $tfile ] ; then
                        rm -f $tfile
                fi
                echo -e "---- Delete file:$tfile -----" >> ${LOG_FILE}
done

echo -e "\n==== Jobs ends at `date +%F' '%T' '%w` ====\n" >> $LOG_FILE

另外，三思老师书还有一个数据库按照表备份的脚本，写的也非常好，这里我就不抄袭了，有兴趣的同学，可以去书中寻找，在274页。
