sersync 实现数据实时同步镜像
rsync服务器端配置：
rsync地址：http://rsync.samba.org/
tar zxvf rsync-3.0.4.tar.gz
cd rsync-3.0.4
./configure
make && make install
vi /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
[web1]
path = /var/data
comment = web1 file
ignore errors
read only = no
write only = no
hosts allow = *
hosts deny = 192.168.1.12
list = false
auth users = backup
secrets file = /etc/server.pass
创建密码文件：格式：username：password
echo "123.com" > /etc/server.pass
chmod 600 server.pass
Iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 873 -s sersync_ip -j ACCEPT
启动rsync服务：/usr/local/bin/rsync –daemon
在sersync服务器的布置：
1）下载安装包：
[root@qyeee ~]# wget http://sersync.googlecode.com/files/sersync2.5_64bit_binary_stable_final.tar.gz
--2012-03-26 12:10:00-- http://sersync.googlecode.com/files/sersync2.5_64bit_binary_stable_final.tar.gz

GNU-Linux-x86/
GNU-Linux-x86/confxml.xml
GNU-Linux-x86/sersync2
2）将sersync根目录放到etc下：
[root@qyeee ~]# mv GNU-Linux-x86 /etc/sersync
[root@qyeee ~]# cd /etc/sersync/
[root@qyeee sersync]# ll
total 1596
-rwxr-xr-x 1 root root 2214 Jun 29 2010 confxml.xml
-rwxr-xr-x 1 root root 1617440 Jun 29 2010 sersync2
3）编辑主配置文件：
[root@qyeee sersync]# vi confxml.xml
<?xml version="1.0" encoding="ISO-8859-1"?>

<regexurl regex="false" match="cms.xoyo.com/site([/a-zA-Z0-9]*).xoyo.com/images"/>
</localpath>
</plugin>
</head>
4)创建密码认证文件：
[root@qyeee tmp]# echo "123.com" > /etc/server.pass
chmod 600 /etc/server.pass
关闭selinux
启动sersync服务：
./sersync2 -d
[root@qyeee tmp]# ps -ef | grep -v grep | grep rsync
root 29544 1 0 16:28 ? 00:00:18 ./sersync2 -d
测试ok！！
有扩展的地方请大家参与修改
