使用rsync服务通过inotify实现触发式自动同步数据

Posted 2020-11-01

  实验拓扑：HK36（Server 192.168.2.102）====HK46（Client 192.168.2.190）

  实验要求：对HK46 /data/目录备份到HK36的/backup/下

 

（1）      rsync服务依赖于xinetd超级服务管理，首先安装xinetd服务

[[email protected] ~]# yum -y install xinetd

（2）      进入rsync修改配置文件信息，将disable = yes改为no，重启服务，查看873端口是否起来

[[email protected] ~]# service xinetd restart

Stopping xinetd:                                           [  OK  ]

Starting xinetd:                                           [  OK  ]

[[email protected] ~]# netstat  -anptu | grep 873

tcp        0      0 :::873                      :::*                        LISTEN      2729/xinetd

（3）      创建非系统测试用户，并对目录/backup赋予用户nobody权限

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

uid = nobody

gid = nobody

address = 192.168.2.102

pid = 873

host allow = 192.168.2.190

use chroot = yes

max_connetion = 5

pid file = /var/run/rsyncd.pid

lock file = /var/run/rsyncd.lock

log file = /var/log/rsyncd.log

motd file = /etc/rsyncd.motd

[backup]

path = /backup/

comment = data for backup

read only = no

auth users = gz

list = yes

[[email protected] backup]# chown nobody:nobody /backup/

[[email protected] backup]# vim /etc/rsyncd.motd  创建登入模板文件

welcome to backup data!

[[email protected] backup]# vim /etc/rs.passwd 创建密码

gz:ggrr50152412

（4）      测试，HK46下创建备份目录测试：

[[email protected] /]# mkdir /backup/

[[email protected] /]# mkdir /data/

[[email protected] data]# ls

22  55  a  aaaaa  erer  kd  s  test

[[email protected] data]# rsync -avz  ./  --delete   [email protected]::backup 

（5）      上传inotify并解压安装

[[email protected] ~]# tar -xvf inotify-tools-3.14.tar.gz -C /usr/local/src/

[[email protected] inotify-tools-3.14]#./configure --prefix=/usr/local/inotify-tools;make;make install

（6）      直接调用命令

[[email protected] ~]# ln -s /usr/local/inotify-tools/bin/* /usr/bin/

[[email protected] ~]# vim /root/passfile 创建密码文件

ggrr50152412

[[email protected] data]# chmod 600 /root/passfile并赋予600权限

（7）      测试

（8）      编辑脚本，并赋予执行权限

#!/bin/bash

backup_Server=192.168.2.102

/usr/bin/inotifywait -mrq --format '%w%f' -e create,close_write,delete /data/ | while read line

do

cd /data/

 rsync -az ./ --delete [email protected]$backup_Server::backup --password-file=/root/ passfile

done

[[email protected] ~]# vim inotify.sh

 

（9）      测试成功
