1安裝
[root@server1 soft]# wget
http://rsync.samba.org/ftp/rsync/rsync-3.0.9.tar.gz
[root@server1 soft]# tar zxvf rsync-3.0.9.tar.gz
[root@server1 soft]# cd rsync-3.0.9
[root@server1 rsync-3.0.9]# ./configure
[root@server1 rsync-3.0.9]# make && make install
[root@server soft]# wget
http://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz
[root@server1 soft]# tar zxvf inotify-tools-3.14.tar.gz
[root@server1 soft]# cd inotify-tools-3.14
[root@server1 inotify-tools-3.14]# ./configure
[root@server1 inotify-tools-3.14]# make && make
install
[root@server1 ~]# yum -y install rsync
[root@server2 ~]# yum -y install rsync
2.配置ssh key信任
server1
[root@server1 ~]# useradd -m rsync
[root@server1 ~]# passwd rsync
server2
[root@server2 ~]# useradd -m rsync
[root@server2 ~]# passwd rsync
server1(創建key並配置server2的信任)
[root@server1 ~]# su - rsync
[rsync@server1 ~]$ ssh-keygen -t rsa (所有選項回車,使用默認設置)
server2(將公鑰添加到authorized_keys文件中)
[root@server2 ~]# su - rsync
[rsync@server2 ~]$ mkdir .ssh
[rsync@server2 ~]$ chmod 700 .ssh/
[rsync@server2 ~]$ mv ~/id_rsa.pub ~/.ssh/authorized_keys
server2(創建key並配置對server1的信任)
[rsync@server2 ~]$ ssh-keygen -t rsa
[rsync@server2 ~]$ scp ~/.ssh/id_rsa.pub
[email protected]:/home/rsync/
server1(將公鑰添加到authorized_keys文件中)
[rsync@server1 ~]$ mv ~/id_rsa.pub ~/.ssh/authorized_keys
分別重啓sshd服務
[root@server1 ~]# service sshd restart
[root@server2 ~]# service sshd restart
3.添加同步腳本
[root@server1 ~]# vi inotify_rsync.sh
#!/bin/sh
SRC=/home/rsync/test/
[email protected]:/home/rsync/test
INWT=/usr/local/bin/inotifywait
RSYNC=/usr/local/bin/rsync
$INWT -mrq -e create,move,delete,modify $SRC | while read
D E F;do
rsync
-aHqzt --delete $SRC $DST
done
[root@server1 ~]# chmod +x inotify_rsync.sh
[root@server1 ~]# cp inotify_rsync.sh /home/rsync/
[root@server1 ~]# su - rsync
[rsync@server1 ~]$ ./inotify_rsync.sh &
[1] 15305
[rsync@server1 ~]$ Couldn't watch /home/rsync/test/: No
such file or directory
[1]+ Done ./inotify_rsync.sh
[rsync@server1 ~]$ mkdir test
[rsync@server2 ~]$ mkdir test
測試
[rsync@server1 ~]$ cd test/
[rsync@server1 test]$ touch yhl.txt
[rsync@server1 test]$ Address 172.16.19.89 maps to bogon,
but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!
驗證
[rsync@server2 ~]$ cd test/
[rsync@server2 test]$ ls
