rsync+inotify同步备份

系统内核要求2.6.13以上

目标服务器，rsync服务端配置，也就是被同步到的服务器

uname -r    //查看系统内核版本
yum -y install rsync
vi /etc/rsyncd.conf
	uid = rsync
	gid = rsync
	max connections = 200
	pid file = /var/run/rsyncd.pid
	log file = /var/log/rsyncd.log
	lock file = /var/run/rsyncd.lock
	timeout = 900
	read only = false
	[redis_dump]
	path = /data/redis_dump.bak/
	hosts allow = 192.168.88.130
	hosts deny = *         //先允许再拒绝
	secrets file = /etc/rsync.pass
	auth users = rsync
	read only = no
	fake super = yes       //新版本需要这个参数，否则无法同步
echo "rsync:123456" > /etc/rsync.pass
chmod 600 /etc/rsync.pass    //权限一定为600，否则同步是没有权限
chown -R rsync:rsync redis_dump.bak    //备份目录属主和属组一定要是rsync配置文件中指定的用户
systemctl start rsyncd

源服务器，rsync客户端，也就是被同步的服务器

yum provides inotifywait
yum -y install inotify-tools-3.14-9.el7.x86_64
vi /data/inotify_bak.sh
	#!/bin/bash
	src=/data/redis_dump/
	pass=/etc/rsync.pass
	/usr/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f%e' -e modify,delete,create,attrib $src |while  read files;do
    rsync -avH --port 873 --progress --delete $src [email protected]::redis_dump --password-file=$pass
    echo "${files} was rsynced" >> /tmp/rsync.log 2>&1
    done
chmod +x /data/inotify_bak.sh
echo "123456" > /etc/rsync.pass     //认证用户的密码
chmod 600 /etc/rsync.pass
nohup sh /data/inotify_bak.sh &

然后再源服务器创建一些文件测试一下，再到目标服务器看看有没有被同步过去
