                      软件版本:rsync-3.0.9
服务器端配置
>需要安装xinetd服务

yum install xinetd -y #rhel

apt-get install xinetd -y #ubuntu

>安装

wget http://rsync.samba.org/ftp/rsync/rsync-3.0.9.tar.gzwget http://rsync.samba.org/ftp/rsync/rsync-patches-3.0.9.tar.gztar zxvf rsync-3.0.9.tar.gztar zxvf rsync-patches-3.0.9.tar.gzcd rsync-3.0.9./configuremake && make install

1.创建配置文件

vim /etc/rsyncd.conf

; port=873uid=rootgid=rootmax connections=10log file=/var/log/rsyncd.logpid file=/var/run/rsyncd.pidlock file=/var/run/rsyncd.locksecrets file=/etc/rsyncd.passwd; hosts allow=192.168.11.0/27; hosts deny=192.168.11.0/255.255.255.224timeout=600 [backdir]comment= for client backpath=/home/backdir/read only = no;exclude=test;exclude from=/path/to/file;include from=/path/to/fileauth users=caide.me[share]comment= backup share filepath=/home/share/read only = yesauth users=caide.me

2.创建密码文件(/etc/rsyncd.passwd)

echo "caide.me:caide.me.passwd" > /etc/rsyncd.passwdchmod 600 /etc/rsyncd.passwd

3.创建xinetd监听任务(/etc/xinetd.d/xinetd_rsync)

vim /etc/xinetd.d/xinetd_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/local/bin/rsync        server_args     = --daemon        log_on_failure  += USERID}

service xinetd restart
