rsync是一款開源的、快速的、多功能的、可實(shí)現(xiàn)全量及增量的本地或遠(yuǎn)程數(shù)據(jù)同步備份的優(yōu)秀工具。rsync軟件適用于unix/linux/windows等多種操作系統(tǒng)平臺。下面這篇文章主要介紹了Linux下rsync命令的相關(guān)資料，需要的朋友可以參考借鑒。

介紹

rsync命令是一個(gè)遠(yuǎn)程數(shù)據(jù)同步工具，可通過LAN/WAN快速同步多臺主機(jī)間的文件。rsync使用所謂的“rsync算法”來使本地和遠(yuǎn)程兩個(gè)主機(jī)之間的文件達(dá)到同步，這個(gè)算法只傳送兩個(gè)文件的不同部分，而不是每次都整份傳送，因此速度相當(dāng)快。 rsync是一個(gè)功能非常強(qiáng)大的工具，其命令也有很多功能特色選項(xiàng)，我們下面就對它的選項(xiàng)一一進(jìn)行分析說明。

常用場景

無密碼同步

服務(wù)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

客戶端

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

有密碼同步

服務(wù)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

客戶端

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

寫入同步

服務(wù)端

vim /etc/rsyncd.conf

#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 
[write_data]
path = /web/rsync/write_data
use chroot = no
max connections = 15
read only = no
list = no
ignore errors = yes
timeout = 120
auth users = hadoop
secrets file = /etc/rsyncd.passwd

mkdir -p /web/rsync/write_data

客戶端

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或者網(wǎng)段

#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 
[write_data]
path = /web/rsync/write_data
use chroot = no
max connections = 15
read only = no
list = no
ignore errors = yes
timeout = 120
auth users = hadoop
secrets file = /etc/rsyncd.passwd
hosts allow = 192.168.2.32 192.168.1.0/24
