一:在服务器上配置备份目录代码:
mkdir /var/lib/mysqlbackup
cd /var/lib/mysqlbackup
二:备份脚本:
vi dbbackup.sh
注:更改username,password和dbname。
输入代码:
#!/bin/sh
#Username to access the MySQL server
USERNAME="username"
# Username to access the MySQL server
PASSWORD="password"
# List of DBNAMES for Backup
DBNAME="dbname"
#date timestamp for log message
DATE=`/bin/date +%Y-%m-%d_%Hh%Mm`
#output file
OUTDIR="/var/lib/mysqlbackup/"
OUTFILE="ip_bindass".$DATE."sql.gz"
#working directory
DIR="/var/lib/mysqlbackup/"
#cd $DIR
# MySQL Backup
/usr/bin/mysqldump --database $DBNAME --opt --single-transaction
-u$USERNAME -p$PASSWORD | /usr/bin/gzip -9 > $OUTDIR$OUTFILE
更改备份脚本权限
chmod +x dbbackup.sh
三:用crontab定时执行备份脚本:
crontab -e
若每天下午3点20备份,添加如下代码:
20 15 * * * /var/lib/mysqlbackup/dbbackup.sh
