1.fullbackup.sh 全量备份脚本 addbackup.sh增量备份脚本

[root@ape-bz2009 data]# ls   /data/shell/
addbackup.sh  fullbackup.sh

2.利用公钥免.ssh登录备份服务器

[root@ape-bz2009 ~]# ssh-keygen

3. 定制备份计划任务

[root@ape-bz2009 ~]# crontab  -e

0 1 * * 0 /data/shell/fullbackup.sh
0 * * * * 1-6 /data/shell/addbackup.sh  

[root@ape-bz2009 ~]# cd /data/shell/
[root@ape-bz2009 shell]# chmod +x fullbackup.sh 

4.执行备份脚本

#!/bin/bash 
#定义备份目录
databackupdir=/data/backup
addbackup=/data/addbackup
addbinlog=/data/addbinlog
#判断上条语句是否存在，如果不存在则创建
[ ! -d $databackupdir ] && mkdir $databackupdir
[ ! -d $addbackup ] && mkdir $addbackup
[ ! -d $addbinlog ] && mkdir $addbinlog
#定义备份日志文件
logfile=$databackupdir/mysqlbackup.log
#获取备份目录
#使用innobackupex工具全量备份数据库
innobackupex  --defaults-file=/etc/my.cnf  --user=root  --password='123456'   /data/backup
mysqladd=$(ls -lt $databackupdir |sed -n 2p|awk '{print $9}')

innobackupex  --defaults-file=/etc/my.cnf  --user=root  --password='123456' --incremental  $addbackup  --incremental-basedir=/data/backup/$mysqladd/

#备份binlog日志
n1=`awk '{print $1}' /data/backup/$mysqladd/xtrabackup_binlog_info`
n2=`awk '{print $2}' /data/backup/$mysqladd/xtrabackup_binlog_info`

mysqlbinlog --start-position=$n2 /data/mysql/$n1  > /$addbinlog/`date +%F`.sql
#压缩备份文件
if [ $? -eq 0 ];then
tar zcf $databackupdir
rsync -av $databackupdir [email protected]:/data/mysqlbackup
echo "BackupFileName:$databackupdir.gz" 
echo "DataBase Backup Success!"
else
echo "DataBackup Fail!"
fi

增量备份：

#!/bin/bash
#定义备份目录
addbackup=/data/addbackup
#判断上条语句是否存在，如果不存在则创建
[ ! -d $databackupdir ] && mkdir $ addbackup
#定义备份日志文件
logfile=$addbackup/addbackup.log
#使用innobackupex工具增量备份数据库
mysqladd=$(ls -lt $addbackup |sed -n 2p|awk '{print $9}')
filename=/data/addbackup/$mysqladd/xtrabackup_binlog_info
if [ ! -f "$filename" ]
then
    echo "Is not increase databak!"
    exit
fi
#增量备份数据  
innobackupex  --defaults-file=/etc/my.cnf  --user=root  --password='123456'    --incremental  /data/backup  --incremental-basedir=/data/backup/$mysqladd/
#增量备份binlog日志  
n1=`awk '{print $1}' /data/addbackup/$mysqladd/xtrabackup_binlog_info`
n2=`awk '{print $2}' /data/addbackup/$mysqladd/xtrabackup_binlog_info`
mysqlbinlog --start-position=$n2 /data/mysql/$n1  > /data/backup/`date +%F`.sql
#压缩备份文件
if [ $? -eq 0 ];then
tar zcf $databackupdir
rsync -av $databackupdir [email protected]:/data/mysqladdbackup
echo "BackupFileName:$databackupdir.gz" 
echo "DataBase Backup Success!"
else
echo "Is not incresase databak!"
fi

 

//查看备份服务器是否备份成功
[root@ape-bz2007 ~]# du -sh  /data/mysqlbackup/backup/
117M    /data/mysqlbackup/backup/

4.在备份服务器上进行日志清理

#!/bin/bash
#定义备份目录
databackupdir=/data/backup
addbackup=/data/addbackup
sqldelete( )
   {
   if [  -d $databackupdir ]
   then
     find $databackupdir  -type d -ctime +7 -ok -exec rm {} \;
         echo "databackup is delete!"
    else
    echo "please mkdir databackupdir!"
fi
}
sqladddelete()
{
  if [  -d $addbackup ]
   then
     find $databackupdir  -type d -ctime +7 -ok -exec rm {} \;
         echo "databackup is delete!"
   else
    echo "please mkdir addbackup!" 
fi
}
sqldelete
sqladddelete

5.  制定代码、静态文件的备份脚本

将以下脚本利用分发系统分发到web服务器上，制定任务计划自动执行。。

#Linux下网站数据定期自动备份与删除脚本
#!/bin/bash
#论坛网页目录自动备份脚本
#论坛数据库自动备份
#自动删除备份目录下面超过10天的文件
#脚本每天早上2点自动执行备份工作
BAKDIR=/data/wwwroot/dedecms.com/
BAKZRLOG=/data/wwwroot/zrlog.com/
BAKDISCUZ=/data/wwwroot/discuz.com/
MAXDAYS=10
find ${BAKDIR} -maxdepth 1 -type f -mtime +$(expr ${MAXDAYS} - 1) -exec echo "Delete {}" \; -exec rm "{}" \;
#将网站目录打包压缩 
tar zPcvf /wwwroot/bak/www.dedecms.name_$(date +%F).tar.gz  /data/wwwroot/dedecms.com/
find ${BAKZRLOG} -maxdepth 1 -type f -mtime +$(expr ${MAXDAYS} - 1) -exec echo "Delete {}" \; -exec rm "{}" \;
#将网站目录打包压缩 
tar zPcvf /wwwroot/bak/www.zrlog.name_$(date +%F).tar.gz  /data/wwwroot/zrlog.com/
find ${BAKDISCUZ} -maxdepth 1 -type f -mtime +$(expr ${MAXDAYS} - 1) -exec echo "Delete {}" \; -exec rm "{}" \;
#将网站目录打包压缩 
tar zPcvf /wwwroot/bak/www.discuz.name_$(date +%F).tar.gz  /data/wwwroot/discuz.com/

rsync -aev $databackupdir [email protected]:/data/wwwrootbak

exit 0


执行任务计划：
#crontab  -e
周日备份计划：
