Always use rsync over ssh

Since rsync does not provide any security while transferring data it is recommended that you use rsync over ssh . This allows a secure remote connection. Now let us see some examples of rsync.

rsync command common options--delete : delete files that don't exist on sender (system) -v : Verbose (try -vv for more detailed information) -e "ssh options" : specify the ssh as remote shell -a : archive mode -r : recurse into directories -z : compress file data Task : Copy file from a local computer to a remote server

Copy file from /www/backup.tar.gz to a remote server called openbsd.nixcraft.in

$ rsync -v -e ssh /www/backup.tar.gz jerry@openbsd.nixcraft.in:~

Output:

Password: sent 19099 bytes received 36 bytes 1093.43 bytes/sec total size is 19014 speedup is 0.99

Please note that symbol ~ indicate the users home directory (/home/jerry).

Task : Copy file from a remote server to a local computer

Copy file /home/jerry/webroot.txt from a remote server openbsd.nixcraft.in to a local computer /tmp directory:

$ rsync -v -e ssh jerry@openbsd.nixcraft.in:~/webroot.txt /tmp

Password

Task: Synchronize a local directory with a remote directory$ rsync -r -a -v -e "ssh -l jerry" --delete openbsd.nixcraft.in:/webroot/ /local/webrootTask: Synchronize a remote directory with a local directory$ rsync -r -a -v -e "ssh -l jerry" --delete /local/webroot openbsd.nixcraft.in:/webrootTask: Synchronize a local directory with a remote rsync server$ rsync -r -a -v --delete rsync://rsync.nixcraft.in/cvs /home/cvsTask: Mirror a directory between my "old" and "new" web server/ftp

You can mirror a directory between my "old" (my.old.server.com) and "new" web server with the command (assuming that ssh keys are set for password less authentication)

$ rsync -zavrR --delete --links --rsh="ssh -l vivek" my.old.server.com:/home/lighttpd /home/lighttpd

===================================================

当需要把服务器上的文件复制到另外的机器上，可用rsync来同步文件。

一、服务器端配置：

# yum -y install xinetd

# vi /etc/xinetd.d/rsync

将如下代码

复制代码代码如下:

service rsync

{

disable = yes

socket_type = stream
