cd rsync-3.1.1
./configure --prefix=/usr/local/rsync --disable-ipv6
make
make install

ln -s /usr/local/rsync/bin/rsync /usr/bin/rsync

server端配置

vi /usr/local/rsync/rsyncd.conf

pid file = /var/run/rsyncd.pid
port = 873
pid = root
gid = root
use chroot = no
max connections = 200

--指定rsync访问的密码,密码不需要和系统账号密码相同

vi /usr/local/rsync/rsyncd.passwd

rsync:rsyncpass

ln -s /usr/local/rsync/rsyncd.conf /etc/rsyncd.conf
ln -s /usr/local/rsync/rsyncd.motd /etc/rsyncd.motd
ln -s /usr/local/rsync/rsyncd.passwd /etc/rsyncd.passwd

chmod 600 /usr/local/rsync/rsyncd.passwd

chown root:root /usr/local/rsync/rsyncd.passwd

启动rsync

/usr/bin/rsync --daemon --config=/etc/rsyncd.conf

加入开机启动

echo "/usr/bin/rsync --daemon --config=/etc/rsyncd.conf" >> /etc/rc.d/rc.local

检查是否加入成功开机启动

cat /etc/rc.d/rc.local

/usr/bin/rsync --daemon

netstat -lntp | grep 873

tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN 10689/rsync
tcp 0 0 :::873 :::* LISTEN 10689/rsync

客户端配置

(1).新建客户端密码文件(客户端不带用户名)

vi /etc/rsyncd.passwd

rsyncpass

chmod 600 /etc/rsyncd.passwd

rsync -vzrtopg --progress --delete root@192.168.5.189::test /ocpyang/ --password-file=/etc/rsyncd.passwd

(3).新建同步脚本

vi /rsync.sh

#!/bin/bash
rsync -vzrtopg --progress --delete  root@192.168.5.189::test /testbak/ --password-file=/etc/rsyncd.passwd

(4).手动同步文件

cd /

./rsync.sh

(5).自动同步:每隔五分钟同步一次

crontab -e

0,5 /rsync.sh
