Linux全网站重要数据备份解决方案

1)要求:

1.领导要求每天00点整备份N台Web服务器内的重要数据，包括备份系统配置文件，网站程序目录，访问日志，并通过rsync命令推送到服务器B上保留，：

备份目录以IP保存，打包的文件按照时间名字保存

2.Web 服务器保留打包后7天的备份数据即可，备份服务器保存6个月的数据

2)实施

第一步:搭建起rsync服务备份及测试成功

服务器端:

1.关闭防火墙和selinux

service iptables stop

setenforce 0

2.安装rsync

yum install rsync -y

3.编辑/etc/rsyncd.conf

#rsync_config______________start
#created by ZhangDejin
##rsyncd.conf##
uid = rsync
gid = rsync
use chroot = no
max connections = 200
timeout =300
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
[oldboy]
path = /oldboy/
ignore errors
read only = false
list = false
hosts allow = 192.168.200.0/24
hosts deny = 0.0.0.0/32
auth users = rsync_backup
secrets file = /etc/rsync.passwd
#rsync_config__________end

4.配置rsync用户及服务器验证用的用户和密码文件

useradd rsync

mkdir /backup

echo "rsnyc_backup:haha123" > /etc/rsync.passwd

chmod 600 /etc/rsync.passwd

注意:密码文件权限一定不高于600，否则服务会报错

5.启动rsync服务

rsync --daemon

客户端；

yum install rsync -y

echo "haha123" > /etc/rsync.passwd

chmod 600 /etc/rsync.passwd

测试备份:

rsync -avz /backup/ rsync_backup@192.168.200.128::backup --password-file=/etc/rsync.passwd
sending incremental file list
./
aa

sent 72 bytes  received 30 bytes  204.00 bytes/sec
total size is 0  speedup is 0.00

第二步:实现本地打包备份脚本开发

1.编写脚本backup.sh

#!/bin/bash
ip=$(ifconfig eth1 |sed -n '2p'|awk -F "[ :]+" '{print $4}')

[ ! -d /backup/$ip ] && mkdir -p /backup/$ip

cd /backup/$ip
/bin/tar zcf bak_$(date +%F).tar.gz /var/www/html /etc/rc.local /server/scripts/ /etc/sysconfig/iptables /var/spool/cron/root /app/logs/
/usr/bin/rsync -az /backup/ rsync_backup@192.168.200.128::backup --password-file=/etc/rsync.passwd
find /backup -type f -name "*.tar.gz" -mtime +7 |xargs rm -f

2.测试脚本

3.添加定时任务

echo "00 00 * * * /bin/sh /server/scripts/bak.sh >/dev/null 2>&1" >> /var/spool/cron/root

4.在服务器端添加定时任务

echo "00 00 * * * /bin/find /backup/ -type d  -name "192.168.1.*" -mtime +180 |xargs rm -f

只检索192.168.1.0的目录，优化find的检索速度
