2.变量文件

[root@host163 opt]# cat /mnt/vars_config.conf

3.备份脚本

[root@host163 opt]# cat /mnt/backup_redis.sh|egrep -v "^$"
#!/bin/bash
#use ruby 2.3.3
source /usr/local/rvm/scripts/rvm
/usr/local/rvm/bin/rvm use 2.3.3 --default
source /mnt/vars_config.conf
#check dir and mkdir new dir if dir not exist
if [ ! -d "$OUTPUT_DIR" ]
 then
   mkdir -p  "$OUTPUT_DIR"
fi
function sent_alert() {
           #get time that 8 hours ahead now
           date -d'+ 480min' --rfc-3339=seconds |sed 's/ /T/g' >bjsj_startat.txt
           date -d'+ 481min' --rfc-3339=seconds |sed 's/ /T/g' >bjsj_endat.txt
           #replace the space with T
           sed -i "s#rfcstartat#`cat bjsj_startat.txt`#" jsondata.txt
           sed -i "s#rfcendat#`cat bjsj_endat.txt`#" jsondata.txt
           curl -XPOST -d"`cat jsondata.txt`" $ALERT_URL
	   }
#begin dump redis data
"$REDISDUMP_CMD" -u $HOST_PORT >"$OUTPUT_DIR"/redis$DATETIME-json
if [[ $? -ne 0 ]];then
                echo "$FAILALERT"  > jsondata.txt
		sent_alert $FAILALERT
                exit 1
fi
echo "$SUCCESSALERT"  > jsondata.txt
sent_alert $SUCCESSALERT
#remove the old data created 6days ago
/bin/find $BACKUP_DIR -mtime +10 -type d -exec rm -rf  {} \;

 执行脚本：

bash backup_redis.sh
