簡潔版如下：
服務器端(目標服務器)：192.168.1.1
客戶端(源服務器)： 192.168.1.2
【服務器端部署】
iptables -I INPUT -s 192.168.1.2/32 -p tcp --dport 873 -j ACCEPT
service iptables save
whereis rsync || yum -y install rsync xintd
sed -i "s/= yes/= no/" /etc/xinetd.d/rsync
vim /etc/rsyncd.conf
uid = root
gid = root
use chroot = no
max connections = 10
strict modes = yes
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
[testYHT]
path = /data/yhtlog/
comment = testYHT file
ignore errors
read only = no
write only = no
hosts allow = 192.168.1.2
hosts deny = *
list = false
uid = root
gid = root
auth users = yhtuser
secrets file = /etc/rsyncd.secrets
vim /etc/rsyncd.secrets
yhtuser:123456
chmod 600 /etc/rsyncd.conf
chmod 600 /etc/rsyncd.secrets
service xinetd restart
【客戶端部署】
whereis rsync || yum -y install rsync
vim /etc/rsyncd.secrets
123456
chmod 600 /etc/rsyncd.secrets
vim /usr/bin/rsync.sh

注意：
如果服務端防火牆配置了只允許客戶端公網IP，則服務器端rsync配置文件也得配置公網IP，而客戶端同步腳本也得配置公網IP，否則全是內網
inotify參數
-m 是保持一直監聽
-r 是遞歸查看目錄
-q 是打印出事件
-e create,move,delete,modify,attrib 是指 “監聽 創建 移動 刪除 寫入 權限” 事件
