环境：
Rsync Server 192.168.0.160
Rsync Client 192.168.0.159
（一）配置Rsync Server
1.安装rsync2.6.5
./configure --prefix=/opt/rsync2.6.5
make
make install
2.配置以服务器模式启动
#vi /etc/x.netd.d/rsync
# default: off
# description: The rsync server is a good addition to an ftp server, as it # allows crc checksumming etc.
service rsync
{
disable = no
socket_type = stream
wait = no
user = root
server = /usr/bin/rsync
server_args = --daemon --config=/opt/rsync2.6.5/etc/rsyncd.conf
log_on_failure += USERID
}
3.建立服务器端目录结构
etc man var
4.配置服务器端配置文件
#vi /opt/rsync2.6.5/etc/rsyncd.conf
log file = /opt/rsync2.6.5/var/rsyncd.log
pid file = /opt/rsync2.6.5/var/rsyncd.pid
lock file = /opt/rsync2.6.5/var/rsyncd.lock
secrets file = /opt/rsync2.6.5/etc/rsyncd.secrets
motd file = /opt/rsync2.6.5/etc/rsyncd.motd
read only = yes
hosts allow = 192.168.0.159
hosts deny = 192.168.100.0/24
list = yes
uid = root
gid = root
use chroot = no
max connections = 4
syslog facility = local5
[mailstore]
path = /mss
comment = whole mailstore area
auth users = mailstore
[maildb]
path = /db
comment = db data
auth users = maildb
[maildatabase]
path = /var/lib/mysql/userdb
comment = mysql databases
auth users = maildatabase
# vi /opt/rsync2.6.5/etc/rsyncd.secrets
mailstore:123456
maildb:maildb
maildatabase:maildatabase
5.设置服务器端配置文件的权限
# chmod 600 rsyncd.conf rsyncd.secrets
-rw------- 1 root root 795 Aug 23 06:21 rsyncd.conf
-rw------- 1 root root 37 Aug 23 06:23 rsyncd.secrets
(注意：这个安全设置很重要，如果不这样做客户机连接服务器时会提示：
@ERROR: auth failed on module smb_recover_files
rsync: connection unexpectedly closed (102 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(165)
服务器端日志将出现错误提示：
2005/08/23 06:32:01 [8388] secrets file must not be other-accessible (see strict modes option)
2005/08/23 06:32:01 [8388] continuing without secrets file
2005/08/23 06:32:01 [8388] auth failed on module smb_recover_files from documentserver (192.168.0.159)
）
（二）配置Rsync Client
1.安装Rsync2。6。5
./configure --prefix=/opt/rsync2.6.5
make
make install
2.编写自动连接服务器端脚本，该脚本可以同时连接多个Rsync Server服务器，并可以从一个Rsync Server同时连接多个备份点。
# vi rsync_client.sh
#!/bin/sh
# shenxiaoran/foundir.com 2005.7.20
# This script gets files from server to local directory to backup.
# It's a month rotating incremental backup.
#
[ -f /etc/profile ] && . /etc/profile
