rsync远程备份服务器

架构的拓朴图如下：

部署实施：

Rsync服务端（备份服务器）：

[[email protected] ~]# uname -r

3.10.0-327.el7.x86_64

#是否安装Rsync服务

[[email protected] ~]# rpm -qa | grep rsync

rsync-3.0.9-17.el7.x86_64

#建立用于备份的账户

[[email protected] ~]# useradd backup

[[email protected] ~]# passwd backup

#建立配置文件

[[email protected] ~]# vim /etc/rsyncd.conf

uid = root

gid = root

use chroot = yes

address = 127.76.88.55

port = 873

log file = /var/log/rsyncd.log

pid file = /var/run/rsyncd.pid

[backup114]

path = /backup/61.177.274.152

read only = false

auth users = backup

secrets file = /etc/rsyuser.db

[backup2]

path = /backup/192.168.10.2

read only = false

auth users = backup

secrets file = /etc/rsyuser.db

[backup143]

path = /backup/183.3.277.122

read only = false

auth users = backup

secrets file = /etc/rsyuser.db

[backup107]

path = /backup/61.111.244.117

read only = false

auth users = backup

secrets file = /etc/rsyuser.db

#建立授权备份的账户文件

[[email protected] ~]# vim /etc/rsyuser.db

backup:backup

[[email protected] ~]#chmod 600 /etc/rsyuser.db

#建立备份目录

[[email protected] backup]# mkdir /backup

[[email protected] backup]#chown -R backup.backup backup

[[email protected] backup]#mkdir -pv {61.177.274.152,192.168.10.2,183.3.277.122,61.111.244.117}

#启动服务

[[email protected] ~]# rsync --daemon

Rsync客户端(客户端操作基本一致，只是备份目录需要根据实际情况决定）：

#建立密码文件：

[[email protected] ~]# cat > /etc/rsync.pass

backup

[[email protected] ~]#chmod 600 /etc/rsync.pass

#建立备份脚本，并且保留20天的备份数据：

#!/bin/bash

cd /root

tar -zcf phpstudy$(date +%F).tar.gz /phpstudy

rsync -arz --password-file=/etc/rsync.pass /root/phpstudy$(date +%F).tar.gz  [email protected]::backup114/

find /root -mtime +20 -name "*.tar.gz" -exec rm -fr {} \;
