Rsync 简单配置，实现文件及文件夹同步功能：
yum install rsync
touch /etc/rsyncd.conf
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock
#secrets file = /etc/rsyncd.pas
motd file = /etc/rsyncd.motd
read only = no
hosts allow = 10.90.3.118
list = no
uid = root
gid = root
use chroot = no
max connections = 30
strict modes = no
[rdata]
path = /data/rsync_data/
read only = no
/etc/rsyncd.conf
启动：
rsync --daemon --config=/etc/rsyncd.conf
同步文件夹 需要 rsync -Rr 文件夹名 ip::目标模块
例子：
rsync index.html [email protected]::rdata
rsync -Rr images [email protected]::rdata
