Linux是一套免费使用和自由传播的类Unix操作系统，是一个基于POSIX和UNIX的多用户、多任务、支持多线程和多CPU的操作系统。它能运行主要的UNIX工具软件、应用程序和网络协议。
介绍
rsync命令是一个远程数据同步工具，可通过LAN/WAN快速同步多台主机间的文件。rsync使用所谓的“rsync算法”来使本地和远程两个主机之间的文件达到同步，这个算法只传送两个文件的不同部分，而不是每次都整份传送，因此速度相当快。 rsync是一个功能非常强大的工具，其命令也有很多功能特色选项，我们下面就对它的选项一一进行分析说明。
常用场景
无密码同步
服务端：vim /etc/rsyncd.conf
#This is the rsync daemon configuration
#global settings
pid file = /var/run/rsyncd.pid
port = 873
lock file = /var/run/rsyncd.lock
log file = /var/log/rsync.log
gid = root
uid = root
#module settings
[share_data]
path = /web/rsync/share_data
use chroot = no
max connections = 15
read only = yes
write only = no
list = no
ignore errors = yes
timeout = 120
/usr/bin/rsync --daemon
mkdir -p /web/rsync/share_data客户端
rsync -avz --progress root@192.168.1.98::share_data /home/hadoop/share_data限制流量同步
rsync -avz --bwlimit=50 --progress root@192.168.1.98::share_data /home/hadoop/share_data有密码同步
服务端
vim /etc/rsyncd.conf
#This is the rsync daemon configuration
#global settings
pid file = /var/run/rsyncd.pid
port = 873
lock file = /var/run/rsyncd.lock
log file = /var/log/rsync.log
gid = root
uid = root
#module settings
[auth_data]
path = /web/rsync/auth_data
use chroot = no
max connections = 15
read only = yes
write only = no
list = no
ignore errors = yes
timeout = 120
auth users = hadoop
secrets file = /etc/rsyncd.passwd
echo "hadoop:password123" > /etc/rsyncd.passwd
chmod 600 /etc/rsyncd.passwd
mkdir -p /web/rsync/auth_data客户端
echo "password123" > /home/hadoop/rsyncd.passwd
chmod 600 /home/hadoop/rsyncd.passwd
rsync -avz --progress --password-file=/home/hadoop/rsyncd.passwd hadoop@192.168.1.98::auth_data /home/hadoop/auth_data或者是
export RSYNC_PASSWORD="password123"
rsync -avz --progress hadoop@192.168.1.98::auth_data /home/hadoop/auth_data写入同步
服务端
vim /etc/rsyncd.conf

auth users = hadoop
secrets file = /etc/rsyncd.passwd
mkdir -p /web/rsync/write_data客户端
echo "123" > /home/hadoop/write_file
export RSYNC_PASSWORD="password123"
rsync -avz --progress --delete /home/hadoop/write_file hadoop@192.168.1.98::write_data 限定IP或者网段
#global settings
pid file = /var/run/rsyncd.pid

lock file = /var/run/rsyncd.lock
log file = /var/log/rsync.log
gid = root

timeout = 120
auth users = hadoop
secrets file = /etc/rsyncd.passwd
hosts allow = 192.168.2.32 192.168.1.0/24更多命令参考
