　　Debian6.0 squeeze
Server1:192.168.1.104
Server2:192.168.1.105
　　安装之前需要Server1与Server2之间SSH互相信任 请参考以下文章：

　　Server1创建/root/test
#mkdir /root/test
　　Server2创建/root/test
#mkdir /root/test
　　#/usr/bin/unison&
推送到后台安静模式运行
　　如果Server1的/root/test想同步到Server2的/root/test2
需要在Server1创建/root/test  Server2创建/root/test2
配置文件为 root = ssh://192.168.1.105//root/test2/
　　其中要注意的是：
1.force去掉前面的#  那就是Server1单向同步到Server2
2.silent = true 是以安静模式运行 否则一直会有以下提示
　　root@localhost:~#  /usr/bin/unison
Contacting server…
Connected [//localhost//root/test ->  //unixidc//root/test]
Looking for changes
  Waiting for changes from  server
Reconciling changes
Nothing to do: replicas have not changed since  last sync.

　　3.path  是指定你需要同步的目录，用ignore指定path中需要排除的目录及文件
　　4.要双向同步的目录都不允许为空 否则unison进程会自动结束  并提示Aborting…
