一、MySQL备份脚本
#!/bin/bash
# script_name: db_backup.sh
# author: Michael Ho
# contact: herui1991@sina.cn
# 172.50.1.119 为专门的备份服务器,需要做一下服务器之间免密码登录
# 备份的数据库名
DOCKER_NAME=zzmysql
DATABASES=(
"managesystem"
)
USER="root"
PASSWORD="ZZ2018info"
BACKUP_DIR=/data/backup
LOGFILE=/data/backup/data_backup.log
DATE=`date +%Y%m%d_%H%M`
cd $BACKUP_DIR
# 开始备份之前,将备份信息头写入日记文件
echo "--------------------" >> $LOGFILE
echo "BACKUP DATE:" $(date +"%y-%m-%d %H:%M:%S") >> $LOGFILE
echo "-------------------" >> $LOGFILE
for DATABASE in ${DATABASES};do
# 物理机版
# /usr/local/mysql/bin/mysqldump -u$USER -p$PASSWORD --events -R --opt $DATABASE | gzip > ${BACKUP_DIR}\/${DATABASE}_${DATE}.sql.gz
# docker版
/usr/local/bin/docker exec $DOCKER_NAME mysqldump -u$USER -p$PASSWORD --events -R --opt $DATABASE | gzip > ${BACKUP_DIR}\/${DATABASE}_${DATE}.sql.gz
if [ $? == 0 ];then
echo "$DATE--$DATABASE is backup succeed" >> $LOGFILE
else
echo "Database Backup Fail!" >> $LOGFILE
curl -H "Content-type: application/json" -X POST -d ‘{"msgtype": "text","text": {"content": "‘$DATABASE‘备份失败"}}‘ https://oapi.dingtalk.com/robot/send?access_token=xxx
fi
done
# 判断数据库备份是否全部成功,全部成功就同步到异地备份服务器
if [ $? == 0 ];then
/usr/bin/rsync -zrtopg --delete /data/backup/* root@172.50.1.119:/home/data/mysql/backup/ > /dev/null 2>&1
else
echo "Database Backup Fail!" >> $LOGFILE
# 备份失败后向钉钉发出告警
curl -H "Content-type: application/json" -X POST -d ‘{"msgtype": "text","text": {"content": "同步到172.50.1.119失败"}}‘ https://oapi.dingtalk.com/robot/send?access_token=xxx
fi
# 删除30天以上的备份文件
find $BACKUP_DIR -type f -mtime +30 -name "*.gz" -exec rm -f {} \;
exit 0
二、注意事项
1.docker 、mysqldump一定要是绝对路径,否则加入到crontab是执行失败的,执行出来的文件是空的
2.access_token=xxxxxxxxxxxxxxxxxxxx 这个值是自己钉钉申请的token值
