rsync+sersync 实时同步安装配置
环境搭建：(服务器,客户端)
首先关闭selinux与iptables
# vi /etc/sysconfig/selinux
SELINUX=disabled
# setenforce 0
# service iptables stop
在使用sersync之前，我们必须安装配置好rsync服务器
rsync (客户端)
一.安装rsync
# yum install rsync -y
# yum install xinetd -y
二.启动rsync依赖服务
# service xinetd start
# chkconfig xinetd on
三.配置：
# vi /etc/rsyncd.conf
uid = root
gid = root
use chroot = no
max connections = 4
port = 873
[test] # rsync模块名，后面配置sersync会用到
path = /home/ftp
comment = ftp #自定义
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.创建同步目录
# mkdir -p /home/ftp
五.配置认证文件
# echo "user:123456" > /etc/rsync.pas
# chmod 600 /etc/rsync.pas
# rsync --daemon --config=/etc/rsyncd.conf
六.重启xinetd使其配置生效：
# /etc/init.d/xinetd restart
七.设置开机启动：
# echo "rsync --daemon --config=/etc/rsyncd.conf" >> /etc/rc.local
sersync (服务器端)
一.下载sersync源码包
# wget http://sersync.googlecode.com/files/sersync2.5_64bit_binary_stable_final.tar.gz
二.安装sersync
# tar zxvf sersync2.5_32bit_binary_stable_final.tar.gz
# mv GNU-Linux-x86/ /usr/local/sersync/
三.配置sersync
1.首先创建连接rsyncd的密码文件
# echo "123456" >/etc/rsync.pas
# chmod 600 /etc/rsync.pas
2.配置confxml.xml
# vim /usr/local/sersync/confxml.xml
按照注释进行修改

3.创建服务器端sersync同步目录
# mkdir -p /home/ftp
4.设置环境变量：
# echo "export PATH=$PATH:/usr/local/sersync/" >> /etc/profile
# source /etc/profile
5.启动sersync
# sersync2 -r -d -o /usr/local/sersync/confxml.xml
重启操作如下：
# killall sersync2
# sersync2 -r -d -o /usr/local/sersync/confxml.xml
6.设置开机启动
# echo "sersync2 -r -d -o /usr/local/sersync/confxml.xml" >> /etc/rc.local
验证：
(服务器端)
# cd /home/ftp
# touch 1
# echo "test" > 1
(客户端)
# cd /hoem/ftp
# ls
1
# cat 1
test
