FreeBSD+Rsync文件同步

安装,服务端和客户端安装一样
woody-207#cd /usr/ports/net/rsync
woody-207#make install

配置rsync服务端
woody207# ee /usr/local/etc/rsyncd.conf
添加以下内容
[www]
comment = web server backup
path = /www
auth users = woody
uid = root
gid = wheel
secrets file = /usr/local/etc/rsyncd.secrets
read only = no

配置rsyncd.secrets
woody-207#ee /usr/local/etc/rsyncd.secrets //加入以下内容

woody:RXHOEqat6Dhon4HRsM31 // 认证所需的用户名/密码 建议设置强密码

woody-207#chmod 600 /usr/local/etc/rsyncd.secrets

配置rc.conf
rsyncd_enable="YES"

启动rsync的daemon模式
ee /usr/local/etc/rc.d/rsyncd
修改这一行内容，使用IPV4协议
command_args="-4 --daemon"

启动
woody-207# /usr/local/etc/rc.d/rsyncd start

检查Rsync daemon启动状态
woody-207# sockstat | grep rsync
root     rsync      586   3  dgram  -> /var/run/logpriv
root     rsync      586   4  tcp4   *:873                 *:*

RSYNC客户端配置
1、配置rsyncd.secrets
woody-207#ee /usr/local/etc/rsyncd.secrets //加入以下内容

RXHOEqat6Dhon4HRsM31 //Rsync Server上的认证密码,不用输入用户名

woody-207#chmod 600 /usr/local/etc/rsyncd.secrets

2、进行第一次同步
/usr/local/bin/rsync -avzP --delete --password-file=/usr/local/etc/rsyncd.secrets woody@192.168.1.207::www /www/backup/

将上面的同步命令写进shell script里面，加一个#!/bin/sh就可以了。

*/1     *       *       *       *       root    /root/rsync.sh

Linux平台下解决方案
rsync: failed to connect to ip地址: Connection refused (111)
rsync error: error in socket IO (code 10) at clientserver.c(94)

rsync进程没有被执行

# rsync --daemon

手写配置文件
/etc/rsyncd.conf
pid file = /var/run/rsync.pid
port = 873
uid = root
gid = root
use chroot = no

[database]
comment = web server backup
path = /var/lib/mysql/test
auth users = mysql
uid = mysql
gid = mysql
secrets file = /usr/local/etc/rsyncd.secrets
read only = no
hosts allow = 192.168.1.208

[root@mysql252 mysql]# more /usr/local/etc/rsyncd.secrets
mysql:RXHOEqat6Dhon4HRsM

rsync --daemon
