Sshd+rsync to realize the principle of data synchronization is simple

The client connects to the server through SSHD, and the server synchronizes the data to the client

First look at the server's kernel information

Server Side

[Root@server ~]# Uname-a

Linux server.test.com 2.6.18-194.el5 #1 SMP Tue 21:52:43 EDT i686 i686 i386 gnu/linux

Client Side

[Root@client ~]# Uname-a

Linux client.test.com 2.6.18-194.el5 #1 SMP Tue 21:52:43 EDT i686 i686 i386 gnu/linux

First, both the client and the server need to configure the Yum source, where I use the local Yum source

Installing rsync and XINETD Services

[Root@server ~]# yum Install rsync xinetd-y

[Root@client ~]# yum Install rsync xinetd-y

Modify/etc/xinetd/

[Root@server ~]# Vi/etc/xinetd.d/rsync

Change Disable=yes to Disable=no

and restart the XINETD service.

[Root@server ~]#/etc/init.d/xinetd Restart

stopping xinetd: [OK]

Starting xinetd: [OK]

The client server does the same operation

Client and server-side SSH services are turned on

[Root@server ~]#/etc/init.d/sshd Restart

stopping sshd: [OK]

Starting sshd: [OK]

On the server

[Root@server/]# Mkdir/data

[Root@server/]# Cd/data

[Root@server data]# mkdir Server

[Root@server data]# CD server/

[Root@server server]# pwd

/data/server

[Root@server server]# Du-sh Test.rar

249M Test.rar

uploaded a file in the server Test.rar

Then create a new file

[Root@server server]# Touch TT

[Root@server server]# ls

Test.rar TT
