環境搭建：(服務器,客戶端)
首先關閉selinux與iptables
# vi /etc/sysconfig/selinux
SELINUX=disabled
# setenforce 0
# service iptables stop
在使用sersync之前，我們必須安裝配置好rsync服務器
rsync (客戶端)
一.安裝rsync
# yum install rsync -y
# yum install xinetd -y
二.啓動rsync依賴服務
# service xinetd start
# chkconfig xinetd on
三.配置：
# vim /etc/rsyncd.conf
uid = root
gid = root
use chroot = no
max connections = 4
port = 873
[test] # rsync模塊名，後面配置sersync會用到
path = /home/ftp
comment = ftp #自定義
ignore errors
read only = no
list = no
auth users = user
secrets file = /etc/rsync.pas
hosts allow = *
# hosts deny = 0.0.0.0/0
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
四.創建同步目錄
# mkdir -p /home/ftp
五.配置認證文件
# echo "user:123456" > /etc/rsync.pas
# chmod 600 /etc/rsync.pas
# rsync --daemon --config=/etc/rsyncd.conf
六.重啓xinetd使其配置生效：
# /etc/init.d/xinetd restart
七.設置開機啓動：
# echo "rsync --daemon --config=/etc/rsyncd.conf" >> /etc/rc.local
sersync (服務器端)
一.下載sersync源碼包
# wget --no-check-certificate https://raw.githubusercontent.com/orangle/sersync/master/release/sersync2.5.4_64bit_binary_stable_final.tar.gz
二.安裝sersync
# tar zxvf sersync2.5_32bit_binary_stable_final.tar.gz
# mv GNU-Linux-x86/ /usr/local/sersync/
三.配置sersync
1.首先創建連接rsyncd的密碼文件
# echo "123456" >/etc/rsync.pas
# chmod 600 /etc/rsync.pas
2.配置confxml.xml
# vim /usr/local/sersync/confxml.xml

3.創建服務器端sersync同步目錄
# mkdir -p /home/ftp
4.設置環境變量：
# echo "export PATH=$PATH:/usr/local/sersync/" >> /etc/profile
# source /etc/profile
5.啓動sersync
# sersync2 -r -d -o /usr/local/sersync/confxml.xml
重啓操作如下：
# killall sersync2
# sersync2 -r -d -o /usr/local/sersync/confxml.xml
6.設置開機啓動
# echo "sersync2 -r -d -o /usr/local/sersync/confxml.xml" >> /etc/rc.local
驗證：
(服務器端)
# cd /home/ftp
# touch 1
# echo "test" > 1
(客戶端)
# cd /hoem/ftp
# ls
1
# cat 1
test
