?準備環境：

rsync服務器：172.16.3.21

sersync2服務器：172.16.3.23

一、?rsync服務器

先把原來的rsync包刪掉yum?remove?rsync-2.6.8-3.1?-y,

然后到http://rsync.samba.org/下載rsync包我用的包如下圖所示

?

利用securecrt上傳本地

[root@acong?tongbu1]#?cd?/home/lincong/tools/

[root@acong?tools]#?ll

total?52084

drwxr-xr-x?19?root?root?????4096?Sep?20??2006?linux-2.6.18

二、?sersync2服務器：??

這里有兩個連接一個是針對64位的，一個是32位的，所以一定要選好否則后面出錯了你排查不到原因，所以在這里叮囑一下。?

wget?http://sersync.googlecode.com/files/sersync2.5_64bit_binary_stable_final.tar.gz?

wget?http://sersync.googlecode.com/files/sersync2.5_32bit_binary_stable_final.tar.gz?

[root@acong?tools]#?tar?zxf?sersync2.5_32bit_binary_stable_final.tar.gz?

測試1：sersync端?

在sersync端新建一個文件，看rsync端否同步?

[root@acong?tongbu1]#?touch?test.sh?

[root@acong?tongbu1]#?ll?

total?0?

-rw-r--r--?1?root?root?0?Aug??3?03:04?test.sh?

查看下rsync端?

[root@acong?tongbu1]#?ll?

total?0?

-rw-r--r--?1?root?root?0?Aug??3?03:04?test.sh?

結論：成功！?

#############################?

測試2：在sersync端先刪除剛才建立的test.sh，在建立一個acong.sh?

[root@acong?tongbu1]#?touch?acong.sh?

[root@acong?tongbu1]#?ll?

total?0?

-rw-r--r--?1?root?root?0?Aug??3?03:09?acong.sh??##只有這一個文件?

查看下rsync端?

[root@acong?tongbu1]#?ll?

total?0?

-rw-r--r--?1?root?root?0?Aug??3?03:09?acong.sh??##也是一樣的?

結論：成功！?

#############################?

測試3：在rsync端建立文件，sersync端是否能一樣呢?

[root@acong?tongbu1]#?touch?xiaolin?

[root@acong?tongbu1]#?ll?

total?0?

-rw-r--r--?1?root?root?0?Aug??3?03:09?acong.sh?

-rw-r--r--?1?root?root?0?Aug??3?03:11?xiaolin?

[root@acong?tongbu1]#?ll?

total?0?

-rw-r--r--?1?root?root?0?Aug??3?03:09?acong.sh?

結論：不成功，因為畢竟不是互為同步的。?

通過以上配置可以實現對目錄的監控，以及實時的進行增量的數據同步。
