关于linux下文件实时双向同步问题

我按照网上的文档通过inotify+unison实现了两台centos服务器的实时双向同步，文档中给了一个shell脚本，我想增加一台服务器与之前两台服务器一起实现双向同步，不太懂shell，不知道怎么改，求大神帮忙，下面是两台服务器的脚本：

server1地址：192.168.20.1
shell：
#/bin/bash
ip2="192.168.20.2"
src2="/home/server1/"
dst2="/home/server2/"
/usr/local/bin/inotifywait -mrq -e create,delete,modify,move $src2 | while read line; do
/usr/local/bin/unison -batch $src2 ssh://$ip2/$dst2
echo -n "$line " >> /var/log/inotify.log
echo `date | cut -d " " -f1-4` >> /var/log/inotify.log
done

server2 地址192.168.20.2
shell
#/bin/bash
ip1="192.168.20.1"
src1="/home/server2/"
dst1="/home/server1/"
/usr/local/bin/inotifywait -mrq -e create,delete,modify,move $src1 | while read line; do
/usr/local/bin/unison -batch $src1 ssh://$ip1/$dst1
echo -n "$line " >> /var/log/inotify.log
echo `date | cut -d " " -f1-4` >> /var/log/inotify.log
done

#server1地址：192.168.20.1

ip3="192.168.20.3"
